- Bosch ABS... probably the last thing you have thought might be of use to your bike - BUT, is it a performance of safety benefit? I check out Bosch's new eBike ABS at Verbier ebike festival.
ETHICS, DISCLAIMER and TRANSPARENCY: Verbier E-Bike Festival hired me to visit the recent festival event to film and feature content on my channel. BOSCH are one of the headline sponsors of the E-Bike Festival, so are indirectly are linked to the video here. Neither Bosch, or the organisers of Verbier E-Bike Festival, have had any editorial or narrative control over the video.
This paid partnership with Verbier E-Bike Festival has allowed me time to film this bike (and others), test various feature of the new Bosch Smart System, ABS, and also film and edit over multiple days working with an independent film crew to help capture and produce video content.

For new riders commuting to work on an ebike riding on wet, slick roads with mixed surfaces I think that ABS would be fantastic. Especially people who are slightly older and don't have years of built up muscle memory and quick reaction speeds. For emtb use I can see how it might help new riders coming into the sport, but I worry that this is just more tech that is impossible to service or repair. We already see many motors that are like iphones. One tiny thing breaks (eg: force sensor) and replacement pars are not available, like an iphone when anything breaks you are told to replace the entire unit.
And unlike iPhones, you can’t buy a fully guaranteed refurb at a discounted price, nor a policy for fix or replace after the original guarantee ends…
@@Coolcmsc I'm quite fortunate enough to live less than 30miles from a company called - "performance line bearings'. He can refurb a lot of out of warranty motors, my 2019 brose for sure.
But this tech right here, i think you could be right. It's going to take a brainiac to sus out. Also depends on what kind of warranty length they offer. Surely if the warranty is spent,they can't moan when people start to strip down this unit to see what is what.
apple got sued for those practices a while back, now they do offer replacement parts.
I don't use apple I use Samsung, because they didn't need to use ads to lie about their product to get sales.
anyways, I have insurance on my phone since I'm always outside, anything breaks I just get an entirely new phone, I use the service probably once or twice a year (the limit is twice a year for me)
usually insurance is too expensive to be worth it, but not phone insurance. I saved a lot of money just having my phones replaced,
sometimes they even just send me the newer version of a phone if they can't replace it,
@@mikee8244 the more software there is, the more software engineers there must be. Some hobbyist will crack the tech and the next and the next. It will all become "affordable" to service and maintain eventually. :)
As long as there is an off. I dont see this getting regulated like motorcycles that go on road...but eventually the tech will be there
I like how you clarified early that the ABS only does its thing on the front wheel, despite using sensors on both front and back. Great video!
I think it was a safety choice as locking just the rear keeps the bike tracking straight
q
Abs can only work if it has sensors on multiple wheels
I don't actually get that part. If the rear wheel speed is the reference point for the abs system, when you apply brake on the rear wheel as well as the front, wouldn't the system lose its reference point?
@@ermanakbay
Nope, because if both wheels are in solid ground they're both going the same speed.
If you apply front brake only, you'll slow both wheels.
If you apply it very hard the front wheel will show down faster than the rear so the abs will detect that the front is starting to lock up as the rear wheel is still turning.
It's just making sure the front wheel is always turning the same speed or more than the rear.
It probably uses motion detection as well to help.
On loose steep sections I really enjoy the challenge of not locking up the brakes. I find it super rewarding when you get it right and if you fully lock both it can be hilarious fun and the fear of not being able to stop is what makes it so fun.
Aside drifting the rear for cornering and stunts, in strait descends or emergency braking, not locking the wheels, any of them, is something that separates experienced riders from beginners. ;)
@ i've been cycling for more than a decade now and realized that unless someone is in a real competition, nobody cares about separating experienced vs beginners except those who want to be egoistic gatekeepers ;)
I've learned to not lock wheels ever since i learned how to ride a bike when i was a kid, and i was beginner back then.
Will be interesting to see an intermediate rider nervous about going down a steep dusty rock slab( thinking something like original sin at whistler) and then a beginner rider with abs show up and execute it perfectly with no sliding just by fully grabbing the front brake.
And then that very same rider getting on a non abs bike and dieing :/
Will also be interested to see what happens when the batteries run out or the ABS computer malfunctions haha
true true but i still believe that everyone should properly learn how to modulate brakes, not just rely on ABS. (just like how we learnt in cars with no abs)
@@godzillaxred then again no one learns to do that these days in cars. Its been decades since non ABS cars were even sold. In fact onw people say it is harmful to learn that as this may lead to wrong reactions with ABS enabled cars. I agree with your point for bikes though, as this is a basic skill and non ABS bikes will always be around.
@@nelly5538 id imagine it’s hooked directly to the ebike battery
Another potential benefit for this tech are for people who suffer from arm pump from super long descents because let's face it, when your arms are sore, brake modulation takes a nose dive and risk of accidents can increase. Having ABS on is good safety solution even for advanced riders that use extremely large rotors where modulation is non-extent with the on-off behavior.
Never had this mythical "zero modulation" problem.
@@FightFilms I drink and drive every opportunity I get, haven’t killed anyone yet!
I've never really had that problem with the brakes. I get it's a decent idea. But pushing the brakes isn't really that big of an effort. Sure it can be quite tiring, but not really dangerous. Also you don't brake at full force most of the time, you brake lightly to avoid locking the wheels so it's not really that much strength that you apply
@@ernestomartinezros9046 technically, the ABS will always outperform humans and shorten braking distance while maintaining optimum traction and stability. the best humans can react is around 120ms while the sensor can respond near instantaneously. The best human control can do is just threshold braking
As you said, trying it on wet roots would be the ticket! Could be a game changer.
I've been curious about this since it turned up at the trade shows, thanks for giving us a look at it in action. Definitely something I'd love a chance to mess around with, the jury will remain out until I ride it but it looks pretty impressive!
Based on me growing up riding motorcycles on and off-road with no ABS and then with ABS it’s 100% better in every scenario apart from when you want to do stoppies
Yeah that's always been my main concern
it's not 100% better in every scenario.
motorcycles go extremely fast compared to mtb.
motorcycles are on flat smooth terrain.
mtb is on rugged inconsistent trails that require more control,
there are many instances where you WANT your wheels to lock up to perform slides and other maneuvers.
abs prevents wheel locking, no more sliding out your back tire at will, you now have to fight against abs to do it.
also, I'm a motorcyclist. in the world of stunt motorcycling, they prefer not to use abs breaks, because they are better at using their brakes than the system is.
the abs system doesn't know what you're trying to do, it just prevents wheel locking.
mtb is cycling sport that requires higher control,
automatic braking systems (abs) is a downgrade in terms of control.
@@selfactualizer2099 someone didn't watch the video.
@@selfactualizer2099 did you watch the video? It's only front wheel
@@selfactualizer2099 First of all you clearly didn't watch the full video. Secondly you can just turn it off if you don't feel like using it for your particular ride.
Great review Rob, loving the new tech and excited for the future
Super interesting. I wonder if theres something in the UCI rulebook to stop this being used in world cup DH racing, with a tiny battery pack powering it. That test where the bike consistently stopped over a whole bike length short, vs no ABS - Imagine the time saving on a WC DH track with that technology and a pro rider.
Absolutely mad. Well done Bosch and Magura.
Of course the ABS is going to outperform Rob Regular here but you'd see a different story with a professional on the bike. His weight distribution on the bike is horrible for braking to begin with. It's consistent for both tests which is OK but not indicative of a pro rider doing the same test. It's not a coincidence that ABS is not used in many forms of motorsport. ABS is more for people not used to fine brake control or conditions where unpredictable events can require sudden unexpected hard braking. This doesn't happen on a world cup downhill track. All your lines and braking points are predetermined at practice. In conclusion I think it would do next to no good in that application.
@@frankthetankricard I think it would be an easy 5 seconds per run for a WC rider. When racing DH the pro riders will, as you say, plan their braking points. However it will be a risk vs reward approach, where braking deep into a loose corner would risk a small mistake for too little gain. With more margin for error as rob has here, you’d see pro riders just pushing harder, because the risk of making a mistake is lowered and the feel of the bike more consistent.
A pro probably wouldnt need it just like moto gp riders dont use abs. They just dont lock up
@@BanjoDo that’s absurd, they don’t use it because it’s not allowed in the rules. Motorsport ABS systems modulate the brake pedal much more accurately and react more quickly than any human ever could - period. It doesn’t matter how good a rider or driver you are, skill doesn’t actually matter - a human brains simply can’t react and modulate the lever at a high enough frequency.
I think you guys are projecting than an extraordinary amount of human skill could in some way replicate ABS. It can’t.
@@Chrissy-H You bring up some good points too. I'm not entirely convinced but we'll see soon. There will be more testing data as the technology becomes common.
I'll be fascinated to see open-source variations of this technology applied in such a way that the rider can tune the ABS to do some "strange" things. Application on other personal vehicles (scooters, skateboards, etc.) could be quite intriguing...
Great explanation of how the system works Rob. Many thanks!
Cracking vid, especially the end bit of reflection. Well done. 👍🏻
I love the fact that you use metric unlike most other MTB-RUclipsrs 👍🏻👍🏻👍🏻
It is amazing to see this kind of tech on a bike. Even as a car mechanic, it is Super fun to se how this system help people ride faster. BUT. I think if people learn to just trust the system fully. And just sends the the breaks to 100%, and expects the system to safe then, and it somehow fails, as complicated systems dos from time to time. They will eate it harder then they would on a non abs bike. It is a dubbeld edge sword.
That sayd great video!
No car mechanic would say that you’re safer without ABS 😂
I think ABS will become more and more common going forward. I can even see it being used front and back, as sacrilegious as that might sound. I fully expect a company to come out with a combined front/back ABS break and a single traditional rear lock up brake, so you can still get back out.
great video mate. enjoyed that one
Love it Rob .... just the same as the skeptics regarding emtbs (I was one), but I learned my lesson. I'll try it first before I make comment but I've no doubt that my next emtb will have the bosch ABS.
Hey Rob rides emtb! Wicked good look at ABS! I've always applied both brakes in all braking situations. I'm not a rear wheel skider! A lot of the trails I ride are not regularly maintained so I don't want to cause excessive erosion! Ride ride ride!
great video. everything i wanted to learn about this system
Great video!
Perfect option for winter 👍. Nice video, thx
Great video Rob , and i hope that fall did not hurt to much , you really put yourself out there mate to make these videos .
As an old car guy that used to work in the motor industry , i have always thought that next to the seat belts in cars , ABS was the greatest single safety feature ever invented for vehicles , and seeing the title of ABS on bikes i was unsure how it go , but clearly it is also a benefit on bikes too .
Cheers .
Great video-thanks! I’d love to try this on my 250W mid-drive, here in Colorado. Instant subscribe.
Hopefully we'll see all disks with the right pattern built in as a matter of course to make retrofitting ABS from any manufacturer easier.
Yayy good one Rob!! Nice to see you in Verbier 😁
Having abs doesn't make your body position good for example,and just because it won't let you lock up the front,that doesn't mean you'll have good modulation,you still need actual braking skills. But it's still a cool thing
I guess if you once try it there is no going back.. great video Rob!!
Great vid - great music!
The final coment I think is the most important. If we get used to this technology will be worse riders for it? will this push us further into dangerous situations or what happens when it fails?
exactly, i'm not a fan...
I know i'm late to this, but as a motorcycle rider... ABS is absolutely incredible. in 10 years of (very defensive) riding, i've triggered it maybe 5 times, but one of those absolutely saved my life - being able to apply 100% braking power in a split second is miles better than what 99.9% of riders can do. Another one probably saved my bike from going down. It really blows my mind how a 400lbs bike just stops on a dime, it's insane.
Now sure, on a bicycle the difference is much smaller, and especially on MTB it's much more about the experience and your own skill. But if you ever take that e-bike on a road, I can only recommend it.
And i'll never ride a motorcycle without ABS in traffic - yes i never really learned how to manually brake well, but i'm glad i didn't have to, and had full power brakes available as a new rider. If i ever end up getting an e-bike i'll definitely look into it, as i commute on bicycle and would definitely enjoy the increased safety, even if i'm always a defenisve rider in traffic.
Rob excelente video👍
Thanks for your statement on the independence of your review, much appreciated and important in this sphere. Interesting review. Look forward to trying it myself.
This actually looks very beneficial, I've flown over the bars after squeezing the front brakes too hard on a trail. If this technology becomes widespread, I'd love to add it to my bikes
Won't help you since going otb is the result of your weight distribution in relation to the braking force.
If anything, the added braking power you can exploit with abs will make it more likely that you'll over balance if grip level increases. The computer can avoid locking up, but it can't tell how much you need to stop. If you are relying on the abs unit to modulate for you, you will be simply using 'as much grip as there is'.
Without actually having to know that yourself, you lose some control.
Nice footage 👍🏻
Exactly as I expected. I like it for some scenarios, but going back to non-ABS means crash. That is a worry.
Wet grass going downhill gives me the willies so I'd love this !!
Rob, your videos are so well done, beautifully filmed, and precise, objective facts that anyone should grasp. I always look forward to them. Thank you. ABS does look like the future must-have or at least should-have tech.
Holy Sh** that's cool! Now you made me wanna have one!
this is absolutely siiiiick!!! although i would hate for racing to become MORE pay to win than it already is becoming. I love it for certain use cases but man... its a tough one morally. Seems like it takes a lot of the thrill out of riding, but I guess I just need to try it for myself! sick vid.
I think it’s necessary to recognise that money is also part of one’s skill set, and is no more or less valid than any other factors such as luck, talent or hard work is for that matter.
So imo, pay to win is a very valid way to win too. Some may invest in time to practice and win, others invest money to buy speed. Nothing wrong either way.
@@slowcyclist4324 that is an absolutely valid point bro.
Bosch Smart System 2 on this bike too. That new mini bluetooth remote is nice.
For those not interested, capable or new to mtbing I can somewhat see the appeal. Personally I think (IMO) people should take the time and effort to learn bike craft rather than just substitute a skill with a technology.
The same can be said about suspension, or bigger wheels. Long travel 29-ners go over stuff really easy. Why don't we ride 26 hardtails instead and take some time and effort to learn skills?
@@Kefir0 actually no, that's completely different. Advancements in suspension and differing wheel sizes are directly correlated with professional mtbers seeking performance enhancement (e.g. "super" enduro and progressive geometry), I'm not aware of any enduro, downhill or xc professionals looking for ABS. The introduction of ABS (IMO) is for the reasons I previously stated.
@@SR104 Correct, better suspension, and better tyres are performance improvements, where ABS isn't a performance improvement, its a safety net.
@@benjy288 Better braking is most definitely a performance improvement. It is also a safety net, but aside from improvements in acceleration the same can be argued that all performance improvements are safety nets. I don't know how you can watch the video where they proved the ABS system stops noticeably sooner with less risk and claim that isn't a performance improvement. Bike stops sooner, that's an improvement. Just like the transition from V brakes to disc brakes which gave improved braking distances/ power was most definitely a performance improvement and not just a safety net.
As far as no professional riders asking for ABS, it is a novel technology for bikes. People generally don't ask for something that is not an option. Unless it is officially banned it will most undoubtedly make it's way onto every racer's bike as it is an undeniable performance improvement. Riders may not even wish to use it, but if they want to be competitive there will be no choice but to adapt once it is available. F1 cars are banned from using automatic transmissions, so they use paddle controlled DSG gearboxes because they shift faster and more reliably than a human with a gear lever and clutch pedal can.
Gate keep less. Ride whatever you like however you like and let other people do the same.
@@kft4764 ABS doesn't give you better braking performance, it doesn't give you more grip, it only stops you from locking the wheel, all this video showed was that this guy didn't feel confident enough to brake harder with ABS off, hence why he stopped quicker with it on, and performance improvements like better tyres and suspension aren't safety nets, they won't stop you from crashing, they will give you a bigger safety margin at a given speed, but you'll more than likely just end up riding faster because of it.
There's no way a professional downhill mtb rider would want ABS, it would more than likely be a liability, motocross bikes don't have ABS, motogp bikes don't have ABS, if it were a performance improvement motogp would be using it like they use traction control, but its not a performance improvement, its just a safety net.
Brilliant tech!
Great. Could imagine it would work very well on ultra steep loose descents too! Would love to see how it handles ice and slick mud too. What next, 2wd ebikes for the ultimate traction?
Seems like it works well. My biggest issue is that it's one more peice of tech that could easily break and surely will not be user serviceable
Knowing Bosch. Almost def not
super reliable zero maintenance on motos. same tech. I want to hate it but it will be a gamechanger.
@@jamesmarchant5837 the problem is going to be liability. If people temper with their Abs and then crash it there will be insurance claims. Definitely in the US. And then it's getting complicated if the end user fucked it up or if it was an inherent problem with the system from the beginning
@@drdentz i'll point to motorcycles again. It's a closed system, the most prevalent "hack" is to pull the fuse and disable the system... Which you can just do here.
I really don't see any reason to tamper with the system if you can already just disable it
Thank You Rob, for this Video.
this system with shimano levers is something i would totally slap on my gravity e-bike^^
since bosch is competing with shimano on e-bike system stuff it will probably not be on shimano breaks ever sadly. but maybe magura is comming up with actual usefull break levers one day^^
Modulating the brakes is all part of the skill and challenge of riding, this could take part of the riding experience away.
Reading the comments, this crowd is certainly different. Remove as many opportunities to learn skill.
That would be a theme for a real challenge with other mountain bikers
In the future i won't be surprised if we'd have AI-assisted self balancing and self pedalling eMTBs too.
Adding weight, cost, complexity, and pulling the skill ceiling down is the future of the sport.
Horse!
I do have that ! It's called regenerative braking, and in combination with torque sensor it's much more efficient than the middrive motor.
Complètement dingue on va finir par inventer la motocross si ça continue 😱 ah zut quelqu'un me souffle dans l'oreillette que ça existe déjà ?!?! 🤭🤭
That's exactly what I was thinking, going back on a non ABS Brake will be dangerous. I'm sure it kind of destroys u're brake finger feeling by the fact u're not the one controlling the pressure!
Seems like a really nice and good working system but may not for everybody. It's nice that Magura is pushing forward and this will probably take some work back from the dentists😉
Also magura levers are very unreliable. It adds cost if they fail, and you can't replace them with shimano levers.
2:35 "Variation" in front and rear-The fly in ointment seems to be if you apply both brakes, and lock up the rear, the system will think it's acceptable to lock up the front as well. Unless it implements some kind of algorithm to detect the rate of deceleration as part of the operation.
5:45 This test indicates the rear is not sensed as was stated earlier though.
Excellent video. I'm sure this will be the future of MTB.
Funny, that’s what a lot analog MTB riders said about eMTB’s until they rode one up a trail.🥴
😆true!
Thats what will happen to class one riders when they ride class 3 :)
I don't need it, but I want to be able to lock up the brakes intentionally for advanced moves. With proper brakes you can modulate and have power.
I suspect that riders at the highest level, with a complete understanding and possession of their bike * may * be able to outdo an abs system. however, for * at least * 90% of riders, this system is a gamechanger.
I do fear for the braking instinct I've developed not being learned, the long term no-service reliability for someone who knows nothing about their bike is an area of concern. additionally, I think braking is good to learn for biking everywhere (what do your braking instincts tell you when you get on a loaner or beater bike?)
I was able to ride a 30 year old hardtail with horrible tires in the rain recently, and I think my braking instinct was the deciding factor between a sloshed-with-mud-miserable crash, and a slightly less muddy safe ride.
Off road abs is amazing on modern adventure motorcycles, it will only get better.
Rob, please, release the evaluation of your latest CHEEB, i'm waiting! Cheers!
This would be amazing on a Surron or Talaria!
Great video about the ABS system. Can you tell us what glasses you are wearing? what is the chest-mounted camera setup?
Would be nice to see how it works on a steep, muddy and with wet roots trail.
More gadgets = more things can break during ride.
Looks amazing, can’t wait until it’s available for everyone. It’ll be like Airwiz etc at first so will be on £10K bikes first.
@Tom Stanton did it long ago. The funny thing is that his design looks a lot like the Bosch one.
What I don't like is added complexity and weight. And I honestly don't know how I could live without locking my front wheel up? I mean switchbacks are one of the nicest trail features.
Rob I like your channel a lot. Those glasses when riding: YES. Those glasses when not riding: HARD NO
What model are the glasses / goggles you are wearing in this video?
Okay, but HOW does it work? How does it modulate the braking power while keeping the system pressurized? Is it the same hydraulic circuit for the rider and for the ABS controller, or are they separated and pressure from the lever is just a setpoint for the controller?
But, How long will it take for UCI to ban it in competition? 😂 for reals tho, EXCELLENT video! It’s the first I’ve watched of your channel, about to watch some more. 👍
Might even be more beneficial for gravel/road bikes with a rigid front fork.
Moving the weight back quickly to do panic breaking is not always feasible. Modulating disk brakes with a rigid fork, more forward geometry and light bike isn't always easy.
I'm certain I would get down those insanely steep loose downhills faster and with considerably fewer washouts if I had ABS. So it's probably both fun and confidence inspiring. But as with all performance enhancing technology I'm hesitant when it takes away from my skills development. But the same thing could be said about having more powerful brakes, which also improves confidence and faster descents.
So I think my biggest concern would be that a lot of the new bike technology we see increases our speed on the trails, which is a potential increased hazard in it self 🤷
Are you going to make a video on the new Evil Epocalypse? ☺
Barely any motorcycle even had ABS 10 years ago. It's crazy that ebikes already have it
Great as a piece of tech but I’ve been riding for 50 years and love it for the challenge not because it’s easy and don’t even get me started on the cost of some of these bikes since Convid
Looks like Mondraker 2023 will have that system then by the looks of that test bike 3:19
Interesting it works when the rear is locked and when the front is rotating faster than the rear. So there must be a line of code dedicated to when the rear is locked, otherwise it wouldn't know how much abs to apply ???
This should be interesting in a world cup downhill event
Will this increase or decrease the amount of brake bumps on trails?
Rob, I do love your channel, I thought you said you are going to buy, with your own money, a Poli Voima? In regard to this antilock thing, up front, on the road, I agree to degree. However, I have to say what you say about skidding the rear brake is what we all do...ahhhh no, I do my level best to never skid the brakes no matter what the situation creates. For one reason, bike control, for another skidding on the trail eventually ruins the trail. I am sure you understand what I am saying where some favorite downhills have been ruined by the shudder bumps that the rear brake skidding creates. I would rather you promote riding without skidding. I am a pretty aggressive rider (now since 1970 before there were any MTB bikes) I have learned to be as fast as I want to be, faster when I want to be than my fellow riders yet not skid the rear wheel. It can be done artfully and be as fast as ever
@Rob: Thanks for the impressive video. Do you happen to know, if the ABS mode was set to "Trail" or "Allroad"? "Trail" would have been closer to "no ABS" than the soft "Allroad".
How does it degrade when the battery goes flat? Eg face out, cut out, warning sound? How long does the ABS battery last?
What happens if you pull the front brake while doing a wheelie?
Neat. Made me think differently about this.
Can't wait for the self driving bikes. Trail keep assist and eye tracking software complete with monthly subscription.
I personally can't wait for self driving cars with monthly subscriptions on everything but the infotainment system which can be used for displaying ads ;-))
If the rear wheel can lock, and the front wheel depends on the speed difference between the front and rear wheels, how does it work when the rear is locked?
Probably checks for rotation on the front wheel alone if the rear wheel isn't rotating?
It likely looks for the speed the front wheel is slowing down. I think it's possible the rear wheel sensor is used for the speedometer partially. Maybe rear speed sensors will be used for traction control in the future, which may be far fetched but who knows
When you were braking in a straight line with ABS on you were locking the rear wheel. If the system measures difference in wheel speeds, how can it work with the rear wheel not rotating?
It just takes additional information from the rear wheel. It will intervene if the front wheel is rotating slower than the rear. It’s not doing anything if it’s the other way around and it relies on the front sensor only.
Hope they still make “analog” bikes
The divide keeps growing and growing. MTB is splitting up into different disciplines. A hardtail rider without motors or gadgets is doing a different sport than an e-MTB rider with electronics and assists everywhere, even if they ride the same trail.
i wonder what happens if you try a stoppie with that system
Maybe the stand still would differ a lot when doing a hard break with the right technique?
Abs has some benefits. I never cared much about my back wheel slipping because mostly I can control it. Yes you can compensate by yourself but it takes a lot of control.
That's the battery/ power requirements for the ABS controller ?
So how does it sense the front & rear wheel speed differential & not lock up the front wheel, when the rear wheel is locked up? Must have additional single wheel sensing, eg speed reduction more than x means the front wheel, is locking up, if it can't sense- use the rear wheel for speed comparison. Nice tech
Would be keen to see the comparison if you didn’t lock the rear wheel and/or put your weight back more. Threshold and panic braking are different honks. Threshold braking is smooth and at the limit of the tires whereas panic is full grab
shame they didn't do dual wheels, like enduro motorbikes, which have the option to turn the rear abs off for slippy trail sections but enable it for more grippy areas.
I regularly lock the front to move sideways into a berm... just a second, leaning all the way back, but this way you can steer into the berm while still skipping staight... i dont want abs, its nonense on a trail, street and high speed yes, but on the trail.... i think someone that can stop fast, move around smooth and fast is in my opinion the one with the most skill.
Perhaps this type of system would result in a single lever braking system just like with cars you don’t have different brake pedals for front and rear.
I believe that the most EMTB riders who have well-skilled may not be required ABS brake system on their e-bikes. Because all is about how to use the brakes properly to stop and achieve stopping power. However, well done, Bosch.
So when you want to lock the front for a second, to lift the rear and move it around, the ABS will put a stop to that. It wont lock. More weight/more complexity.
The index finger can be trained to run the brakes, its about learning to ride a bike.
ABS is already in that finger, with practice.
Can this be ran with a manual bike/ not e-bike?
