- Pinion's new Motor Gearbox unit ditches the traditional derailleur, cassette and chain. Virtually maintenance free, electronic shifting, auto shift, even when stationary, this is a stunning piece of tech!
Eurobike 2023. 
Спорт
Now this is the revolution I was waiting for. No more bent or torn off derailleurs, no more chain and cassette cleaning after a muddy ride, no more chain lubing and fussing over drivetrain service and finally possibility to shift under load with a gearbox. We need this on all ebikes, it's high time to say goodbye cassette!
Totally agree with you! 100% what we need! I am switching to Linkglide this summer but hopefully my next bike will have this system!
Yes its fantastic , i have a recumbent trike with a super long ,ugly ,ugly ,ugly chain and gear system , this would instantly transform it into something so much more user friendly .
If this came as an assembly that needed a tailor made frame …… i would happily alter the frame to accomodate it.
Again …. I want one !
You still have to change the oil in the unit. Also, given how bike industry is, anyone who buys this in the next 5 years is gonna be the beta tester. Im sticking with my chain for the time being.
Incorrect.
You hit it on the nail
That is why this ebike motor is a paradigm shift in ebike evolution.
It completely changes the trajectory of ebike design and philosophy.
But the most important is the technology that it opened.
Now, Bosch, Shimano, Yamaha, Brose, TQ, and the other top ebike motor makers could not simply ignore this marvel of ebike motor technology.
The most innovative product to hit MTB in decades. I really want an ebike with this!
This is some awesome tech, game changing even!
I'd like to comment specifically on the belt: I have a Pinion Gearbox on my hardtail MTB with a Gates Carbon belt. I also have a single speed MTB with a Gates belt, and they have both been great. The belts last about 3 times as long as a chain. They are built to automotive standards. However, the fibers are arranged to be strong lengthwise, not necessarily widthwise. So when handling the belts, you need to be somewhat careful with them. Folding them, prying them into place, twisting them while in place, or banging them into rocks can potentially damage or weaken them.
Also, in dryer climates they do start to squeak a bit and need to be sprayed with silicone lubricant after about every 50 miles or so. Pouring water on it stops it for a few miles, but the silicone spray really helps. You do not need to clean the belt before spraying it, a dusting of material along with the spray seems to be helpful out here in the desert. Take care of your belt and it will take care of you!
I remember seeing the first E-Bike and then the little motors that people started getting for their bikes... etc... I recalled seeing a small motor on like a 12 speed back in the late 70s... early 80 - 81.. But this is So impressive... I mean its Actually about time... ive bn waiting 10+ years for a true Boom in Tech that I kinda gave up waiting... This is So Awesome... This is what they have Started doing with Motorcycles a year or so ago A company did a model of their Motorcycles then Yamaha just put in for their own pattern in this kind of gearbox.. So we are all going to see some major improvements in so many areas of life. Just Imagine a gear box like this in every vehicle eventually. Many wouldn't that be Awesome , Especially if they are built like this. Great Video Bud.. Thanks... P.S. Subbed
This is a paradigm shift in the evolution of ebikes.
It’s hard to deny seeing something like this and not thinking, “This is the future.”
@@andrewwastaken2he future is when there is an ebike with motor that is powerful enough to not need gears in the first place. There are mid drive units that are capable of putting out 5000 watts at almost twice the torque of this thing but of course we will never see a clean integration of those into the bike frame because people are pissy about ebikes having too much power.
like a bafang midmotor and an autoshift Nuvinci rear hub…except better because of the weight distribution.
@@mtvkelby1377how about how cars are unfathomably more inefficient
Its cool just like their regular gearboxes. But it's not going to be anything but a niche product. I spent 10yrs working for 2 of the top 10 bike shops in the country and we were lucky to sell 3 a year. This will never become popular enough to change the industry
This is the way
This is the way
weight and reliability will be the thing, but this makes way more sense on ebikes than pedal bikes. wouldnt be surprised if this does end up being the standard, this time
Legend has it the gears are forged using beskar.
Please when is this available?
You said exactly what I was thinking!
I have been waiting 5yrs to see this, I always wanted a gearbox bike, and also wanted an ebike I thought it'd be great to see them mashed together, it's finally here!
Valeo+effigear year ago .....
Ryan, I want you to be first in line because you are so excited.
Very low power motor, difficult serviceability and very high cost.
Please be first in line.
You can join Rob and be the spokesmodel champion.
On our left as I pass you on an ebike with 2 x's the power and 1/3 the cost.
@@lukewalker1051no derailleur, no drive train maintenance. This has to be the future. Eventually they will figure out some sort of synchronized and you will be able to shift at full power too.
Same - genuinely surprising it took so long to hit the market. Cost aside, this design makes so much sense.
Completely agree. I am over chains, cassettes, and derailleur. The only problem is this bike in the vid is probably $13k 😂
So exciting! Congrats again to Pinion for this world first innovation and we're looking forward to a strong partnership! 🤩
It isn't a worlds first innovation. This has been used in a ton of motorsport applications.
@@notfiveo Is it like US$15,000?
As someone who has been riding bikes for 54 years I never thought I'd see something like this. Our kids are really going to be in a better world which makes me feel so much better. Good job Pinion!
Adding a bunch of electronics to a thing that already did what is supposed to is not making the world better.
@@cholst1it does
They will more than likely fatter and weaker too.
Yeah our kids are gonna be in such a better world, pedophiles everyhwere, satanic shirts at target and a school board who doesn't protect them yayyyyy
Not to criticise the amazing work they present here. But the elegance of traditional bikes also comes from the simplicity of production, low price and resilliance. I wonder how much maintenance is needed for this system.
Once again I appreciate new technology developpement and this looks revolutionary. But it wont be accesible for the average Joe...
(I guess a way longer and precise list of Pro and Con could be made by a bike specialist, I am just a Joe ^^ )
I love it when a company both listens to what their customers want and leads them based on the possibilities that the technology can bring. I love super lightweight road bikes but I also love exploring rugged countryside.
Don't need an ebike to explore the "rugged countryside"😉
these guys dont need customer ideas. they ride, they engineer, they work hard. they are not stupid. this took a lot of time and money. not customers ideas. truth.
@@veganpotterthevegannobody cares what you need.
They could make a gravel bike, just do a different switcher, one for each side, smaller and be done with it... doesn't even need to integrate with the brake leaver.
@@gregknipe8772 nearly EVERY company takes customer wants into account when they design things.
This is more than amazing. First time in my life I'm considering changing a bike because of technology upgrade. Wow.
That's possibly the best advert for an e-bike motor I've ever watched. The revolution we've been waiting for. I hope to see it on a commuter bike soon!
Excited to see the use of a belt drive. Long time coming. I could almost hear your heart pumping faster with excitement Rob lol
This is a game changer! 💪💪💪This makes more sense than traditional drivetrain. I can't wait for more companies to build their ebikes around this system.
Let's hope it works on the trail as I can't see you opening it up with your multi tool to do a quick adjustment.
This makes more sense then a traditional drivetrain? But you guys seem to fail to mention how easy it is to have spare parts/ repair a traditional drivetrain on the go compared to something like this…your definitely letting your excitement get ahead of you.
@TheOnlyKontrol if it's not something you're interested in dont buy it when it comes out. There's plenty of us who are tired of bashing and breaking derailleurs, snapping chains etc who are stoked for this.
@therealgoody heavy and inefficient are the only 2 drawbacks, both of which don't matter on an ebike. That's why it makes more sense on an ebike you get all the benefits 💪
Considering how many reducer gears (or belts) you have inside all mid drive motors, this makes all the sense! What's the point of having all those gears inside and still needing a cassette to change gear ratio?
having everything combined in one unit is great for countless reasons….when something does go wrong, the complexity of repairs is greater, however. Beyond many cyclists ability. But if it’s as durable and trouble free as advertised, I’d like to try one out. cheers from northern Canada!
@@Lorin-GabrielLeaua-fm1lw yes…serviceability is a key point
Delighted for Pinion... superb, always been totally behind this technology 100%. I've been wanting this to happen for many, many years and to retire the antiquated derailleur technology which has served the cycle industry well for many decades but is being kept artificially alive. Hopefully this will be the next big leap forward in not just EMTB motors but the cycle gearing industry overall by developing new gearboxes, we have had several enclosed units over the years but this new impetus could help revolutionize the cycle industry.👍
that belt tensioner looks great, the rest i could take or leave. good to see a pinion with a trigger shifter
So excited for this! I’ve used and loved Pinion’s gearbox before, and I always thought that integrating an electric motor would be perfect.
I can’t emphasise enough, just how much better the rear suspension performs with the cassette and derailleur removed👌
It's finally here!! Stoked to try this sometime soon hopefully - been holding off on the electricity and turning the classic analogue Pinion in anticipation of this!
I hope the electrics and software hold up over time, It's been my main picking point with buying and Ebike.
Looks amazing. When does a mtb become a motorbike?! (what constitutes an mtb?)
Looks the dugs danglies!! Any thoughts / insights on whether Deviate are looking to do an ebike frame with this?
@@mikkg05 I genuinely have no idea, I doubt it atm.
No chain, no cassette, no broken or bent derailleur hanger, this is the wave of the future ❤
Be an early adaptor Rod. You need to buy one now even though you have no idea what the tradeoffs are.
@@lukewalker1051 gearbox and belt drive bikes have been around for a while now
@@dezzydiamond7121 The trade off is that you might as well get a Surron or a Stark when they come out. This thing is pointless in terms of mountain bikes.
@@bindingcurvenot on high end emtb though.
Way overdue and much appreciated!
Been riding a Pinion 12 speed [P-12} with belt drive for over a year now. Fat tires in snow and on ice in winter. Med tires on mud, gravel, and rock in summers. It works flawlessly. I NEVER have to look at the chain to see if it needs maintenance. It's such a relief that every ride, I can just finger check tire pressure and brake sensitivity and go. This system will be even better when I'm a bit older and possibly in need of battery/motor assist. Wish it would fit in place of the C-12 on my current frame, but that's a minor point for such a well-designed product. Thanks.
This is so exciting, I can’t wait to try the next generation of eMTB 😍
If this is reliable it’ll be game changing. Kudos to the pinion team, pioneering. Now we just need bike manufacturers to agree to a universal motor and battery mount so we can put whatever motor we want in their frames 🙌
Pinion hasn't pioneered this. Valeo did.
im sensing new Strava records for you David , all that unsprung weight moved to sprung and mass centralised it has to be good for you.
@@kwhatten And its all inspired by the tech from motorsports industries.
Finally some real innovation and problem solving from the bike industry. This gearbox was pretty niche for analog bikes but makes total sense combined with an ebike motor. Good job Pinion!
They also work great already with rear wheel motors on speed pedelecs such as my commute bike (Klever X-Speed Alpha). But for offroad/full suspension bikes that's obviously a big no-no. Well done PINION!
And it will continue to be niche because this thing costs an arm and a leg.
this is amazing!!!
Thank you rob for bringing this to us, but now you made me want to change my ebikes.
This is amazing actually. Only issue is going to be the pricing. Pinion has a massive advantage on this one and bike manufacturers are going to ask for a premium.
Not really, Valeo/Effigear has the same tech since 1 year ago and I count 2 other startups with similar tech.
@@hokkosQuite often when something this obvious but revolutionary pops up in multiple places around the same time it's because some old patent has expired. I can't say if that's the case here yet but it wouldn't surprise me in the slightest.
this is a 8699 euro bicycle
A manual pinion gearbox is at 2000+€. Add motor and batterie you will be in the 3500€ ballpark without a bike 😁. this is a premium product. But because it wiil be mass produced compared to the manual pinion gerabox the price will come down.
My Bosch Rohloff E14 combo does most of those things already and has done for years… Gates belt drive, big gear range, sealed gearbox, no cassette or derailleur, electronic shift, starting gear, gear change when stationary or pedalling, annual oil change, etc.
Great to see there will soon be another option though 👌
The system you quote is good BUT bad for full suspension emtbs. The unsprung mass of the hub has a big negative effect on suspension performance.
@@leedove7255 the difference between the Rohloff and Gates and a SRAM 1x12 set up is less than 200 grams... and for the wet weather performance (especially in mud - i live in the UK) i'll take that 200 grams any time. My water bottles weigh more than that 🙂
It is not the increase in overall mass which I agree is small but the location of the extra mass. I am comparing it to the Pinion system not a sram cassette and mech setup.
@@leedove7255 ah yes. Fair comment 👍
But I’ve been running my set up for a few years already and this pinion isn’t actually available to buy yet…
I was just thinking about the Bosch and R14 combo compared to this. One other benefit of this pinion setup I could see would be wheel/tire swaps, creating a sort of dirt bike/supermoto setup. (One set for mountain terrain, one set for more paved surfaces) Since there wouldn’t be a need for having an extra $1k+ hub on the spare rear wheel as there would be in the case of the Bosch/R14 setup.
This is incredible. Never thought I’d be this excited about a new motor. This is a very real revolution in the industry, and the competing companies better have their engineers on competing with this right now.
It will blow your mind in performance, as well as your bank.
Just Awesome. I hope a good variety of emtb manufactures get onboard with this as an option in their ranges.
This is amazing. I know bike component companies have tried to do this for many years with little to no success. I’m not sure what all the disadvantages have been in the past and how this might eliminate those issues with e-power. Will be really interesting to see this tech develop. I bet it isn’t too far off, and then we might see CVT type transmissions soon after.
Not sure Components companies tried. Am pretty sure they bought out lots of patents, so there is no competition and they can keep on selling us their products...
There is already cvt Type, lookup enviolo automatic
I’m thinking, to our perception, while riding, this setup with its predictable gear mode would likely seem like a CVT.
That is, till we ride one with a CVT 😂.
This is the Mega Revolution. I've been waiting for this. Congratulations, the best idea and progress in recent years No chain No derailleurs Zero cleaning
Thank you from Truckee California
An improvement not mentioned is that of the chainline.
No more wildly angled chains stretching to reach the 52t cog.
Yep, if you didn't want the belt drive and go chain and sprockets, the chain would last for ages.
This is absolutely amazing ! Though I don't ride ebikes and probably won't until I'm a bit older, this appeals to me for a really durable cargo bike build
That's like saying, "cars are neat but I don't think I'll drive until my horse dies and I sell my buggy"
Pinion making my dreams come true! This is a huge step-change in e-bike tech like what we're seeing with electric vehicles. Great presentation by the Pinion rep. I can't wait for gearbox, belt drive, and electronic shifting tech to come down in cost in the years to come. Good riddance to chains! I hope they are working on regenerative electronic braking next to eliminate freewheel whiz and minimize physical brake wear (and of course gain back energy on those descents).
Revolutionary... I've been thinking about a gear system that would remove the derailer from the rear. I thought of a system that was in the rear hub, didn't think of it in this location, it's brilliant!
This is the future right now. What manufacturers are going to run this system then, and there's the price. Can't wait to see it in action. 👌🏻 ❤️
Instantly loving this! This is the way ebikes should be made and I will definitely consider one for my next bike now. Well done, Pinion!
Now I want to ride one. Thank you.
Absolutely killer bike. Love that shifter.
Awesome news report Rob. That is the most interesting development I've seen in eBiking. This would totally make me look at bike brands I've never considered before. Let's hope many manufacturer's get on board with it. How come they didn't offer you a ride ???
It’s a great start. Look forward to refined versions in the future. One issue is that it sits lower than the BB and in particular that ‘spring’ - and that is a huge issue in technical terrain. So good to see innovation!
On a standard bike, the chainring also extends way below the BB...
@@altair7001 sounds like theirs room for a bash guard! lol cheers!
Awesome ! Can't wait to get my hands on one.
This is the motor I have been waiting for :-) Been riding EMTB for 5 years and we have 3 in the household. My next next will have this motor! Only negative is that tensioner hanging underneath, looks like it may be prone to rock strikes (a DW high pivot design could fix this and make the rear sus even better) . With all the talk of the new Bosch 600w peak power this seems to offer the same.
This doesn't offer the same as the SX, the SX are much smaller, lighter and weaker, this is more like an regular CX with a gearbox.
@@Echoes-cx torque but sx power 🫤
Why not just get a normal mountain bike and use the ol legs.
@@corail53 I have several "normal" MTB's from trail to DH. I also like EMTB's.
I use a Rohloff derailleur on my bike, but this might be even better because of the centered weight. The only weak point I can see is that the belt tensioner will catch on a log and break it off.
Great interview .. I want one.
Coming from a life with motorcycles, this is what I have been waiting for.
As someone who drives bike a lot in the city, I admire this technology and I hope it will become available, and most importantly, affordable, for city bikes.
Awesome! Thank you you Pinion, thank you Rob. It’s been overdue about 30 years. Now, next step, add regenerative braking, maybe some sort of clutch engagement on the rear hub when the brakes are activated to spin the motor via the belt to recharge the battery. (Even if it added a pound or Kg. Then… perfect!👌😉
unfortunately, you can't regen motors with the belt tensioned by jockey wheels like that, since you'd need the belt tension to flip sides when braking (pedalling pulls along the top of the chain, but braking is reverse, so bottom pulls). maybe if it was more like a single speed bike frame, tensioned by the whole rear axle screwing in and out...
@@BrennanLetkeman correct! Also because of the small amount of weight of a bicycle the amount of regen you get is minimal due to drive losses and with current technology not worth the added complexity and weight.
This is massive. I'd recommend waiting a few years while early buyers beta test them but this could be the future
right i see the belt drive being a problem
This is amazing!! Less maintenance had me sold!
For the 1st time in a long time... im looking forward to testing one of these
I didn't understand one thing. if you are left on foot without a battery, the shifter which seems to be powered by the battery does not work either, did I say right?
Like the Di2 electronic shifters, most likely the motor stops assisting way before the power to shift runs out. You'll probably have hours of shifting to get home.
Wow! That looks amazing! I was disappointed you didn't get to ride it though Rob. Will you be making a video showing you riding the bike in different terrain? Did you ride it off camera? How was it? Do you think this will be coming to other bike manufacturers soon? Next level bike tech for sure!
holy crap I've been waiting for this!!
Boom! Mind blown . Finally, this is what everyone’s been asking for!
A few questions :
What happens when you run out of battery ? Is it locked in whatever gear you where last in ? Or does it automatically go into a default gear that will still allow you to still use the bike as just a normal one gear bike ?
Can you buy spare batterys , gearbox and motor parts on line , or can you buy the whole motor gearbox assembly?
Will there be a kit for the general public ?
How much will it cost ?
I want one ?
😂
I could IMAGINE at least that when the battery level is low enough to cut out motor assistance, there will still be enough juice to do X amount of shifts
@@Draxel Yep , and perhaps some sort of a warning to select an appropriate gear before running out of juice if need be .
Cheers .
There’s around 1000 shifts left when the battery hasn’t got enough power for motor 👍
Yes. 1000 shifts approx.
Hey Rob rides emtb! I love the coming gearbox revolution because of almost all the benefits the pinion rep pitched. I hope there will be a chain version of this or a belt that has some sort of mud clearance holes. Belts don't work on off road motorcycles because the belts heat up from flexing and mud dries and packs into the holes the sprocket teeth engage into. Chains are self clearing. You must love that discreet control pod! Ride ride ride!
I have a Gates belt drive on my emtb and it works better than any chain - especially in mud.
agree, mud will be a big issue for this belt system
You can still use a chain like any current pinion gearbox bike but the gates belt is already very capable off road. I have a friend with a Zerode and a belt drive and he has had zero issues with it, mud or no mud.
@@streddaz its true, they are pretty capable. but they can have problems too.
ruclips.net/video/JO8466-4NSs/видео.html -- this guy broke one when he installed it wrong, and yeah, don't do that, but, still getting stuck out there in the muck sucks
@@pox05 His broken belt had nothing to do with mud. It was improper installation. He even says as much in your link
This bike looks Amazing, I’m going to try and find one ASAP for me and my grandson 👍👍
Wow game changer for emtb!
RIP - derailleur/cassette/chain, you won't be missed.
I think Pinion just 1 upped Shimanos auto shift! This is truly proper! All mid drive ebikes will go to this, its obvious now.
I have a pinion gearbox on my Zerode Katipo and love it. If Zerode put this in a bike and made their first eMTB, I'll buy it in a second to replace my current eMTB. Or, would love to see Pole put this in the Pole Voima (which is my current eMTB). Again, I'd buy it instantly. Will be interesting to see what brands bring this to market in their frames. If the geo works for me, they will get my business because chain/derailleur is my only dislike of my last two eMTB and, having enjoyed my Zerode, I'm now sold on gearboxes and belt drives.
Yes, and updated Taniwha with a motor would be awesome!
He tackled all of the most burning questions head on, this gave me a lot of confidence in the product.
That is just amazing. I was waiting for it.
Not only great for MTBs, but this would be exceptional for a real-world commuter! I've had a few Alfine 8-11 units and for hard-core city use there is nothing better, overall. This, though, is such a huge improvement. Can't wait!!!
How is this good for mountain bikes? The whole point of a mountain bike is to well bike. Use your legs if you can (this system is more ideally suited to those awesome mountain recumbent bikes).
Spring 2023-Sram: no more derailleur hanger
Summer 2023- Pinion: no more derailleur
😂😂😂
Things went quickly nowadays😁
Can't wait the the long range touring/commuter cargo bike version! I know this is a mountain bike, but still amazed that mirror is not included, as for me is number 1 safety add on, better than a helmet for keeping you safe. While I'm dreaming, wouldn't mind wider hubs with bigger bearings, wider hubs also make it easier to replace spokes (don't care about slightly more weight). To save weight, make it stiffer and allow easier replacement of belt, make it single arms instead of forks.
I'm keen to see your test ride on this beasty, thank you.
I hope these work out. Time will tell on reliability.
Yes, hopefully the motors wont break too easily. Because now you have to buy motor with gearbox if it breaks 😅
I won't have money for en e-bike for about a decade, but this makes my heart race. This is a total paradigm shift and I think the big brands can take notes, especially regarding the automatic shifting integration. I'm not sure how I feel about auto shift, but the way they implement it makes so much sense.
That's about how long it took me to get a good bike !
@@guringai I actually bought my very own good bike 2 years ago, so now I'm tapped out again 😂. I love the sport, but it's EXPENSIVE 😜.
Its a piece of art and transportation at the same time
If these guys (Pinion) do not bury their heads into their butts (like Shimano and Bosch), and make this serviceable. They could eat the entire market.
If this somehow would fit to replace the catastrophic ep8 (I am about to pop in the 3rd one and have no hope it would last 1000km) ... they would sell like hotcakes.
ps: I have no idea what hotcakes are ...
Or restrict it electronically also qualifies for burying head. Right now only bafang allows unrestricted setting with the Uart
@@TheAETHER22 Well, yes and no. If you want to allow it on the streets (as a bicycle) and bike parks, it has to be a CLASS 1 bike.
@@TheAETHER22 At that point, just get a SuRon, some companies actually have to exist in the E.U.
Looks amazing! But what's the spring under the bottom bracket, it tensions the belt drive? Seems very prone to rock hits, not?
Matey , that is pretty much out of the way , to hit that with a rock would be a very very extreme case , i guess if it really worried you , you could fabricate a guard for it , but its small potatoes , if you managed to hit that tensioner with a rock , then you are riding in an extremely harsh manner , and deserve a good kick in the bollocks for not having some mechanical sympathy for your bike.
It's the same tensioner that on current Pinion bikes and they have pretty much sorted the bugs out of it and I haven't heard of it being prone to damage.
@@mikldude9376or harsh terrain. I ride EWS enduro trails daily in the Tweed Valley and the bash guard on my YT Decoy Shimano motor has a lot of marks on it. It may not be an issue but cannot be dismissed as bad riding, just depends on the use case.
Almost unbelievable an incredible piece of kit🍻
Wow amazing! This is the way. Now I might actually consider switching.
This is a game changer!! Next bike I’ll buy will have this!! Awesome 🤩
About time. This I have been waiting for.
Finally, after two years of searching,,
This Is It @!
Cheers
Pretty cool. A whole segment about a bike that no one rode.
Got to love that Gates Carbon Drive. Clean and quiet.
Its crazy they managed to get the motor and gearbox so small, incredible how far electric motor tech has gotten.
this is huge! id love to try this out, especially for bikepacking
Really like the idea of automatic shifting only while coasting. I often have to guess how to shift, when I rolled down a slope or up to a junction/corner.
I worked on car and truck transmissions and this is a real transmission just smaller , it's a lovely set up
This is an amazing bit of kit 👌
Great development, congrats! I want a Cargo bike with that
Done and DONE. I have a pinion and would NEVER go back to derailleur and don’t want rear hub motor. This is the solution we’ve been waiting for. Wow!
Brilliant. Just brilliance.
Amazing piece of tech!
Seriously beautiful bicycle in so many ways.
The under-frame tensioner spring looks cobby and vulnerable, but a torsion spring or another solution should be pretty easy.
Genius. It’s about time!
Thank God -- we still have innovative people --- This looks promising for cost efficient exercise and urban transportation
This is so cool! My how the world / technology has evolved in the last two decades.. The gear train looks fantastic!
would love to try this!
Revolutionary system. Absolutely brilliant. 👍
This is why I've been holding off upgrading to a new bike..
This is just a totally new level.
This would be really good for my. My Turbo Levo has taken so much wear to its chain and gears, with the chain having snapped 4 under the sheer force put into it.
It is a beautiful bike ! ❤️
Looks great! Would like to test one in the future
