Andy Kirby performs a pedal-assist range test, using moderate power levels and encountering occasional hills. He documents various checkpoints and the corresponding battery voltage. At 6.1 miles, the battery voltage drops by three volts. Andy continues the test, reaching 10 miles and then turning around. The battery voltage remains stable at 37 volts for a significant portion of the test. He faces challenging terrain, discusses puncture prevention, and experiences changing weather conditions. Despite the obstacles, the e-bike covers a total distance of 18.6 miles with a battery voltage of 33 volts, showcasing an impressive range for this setup. The video concludes by highlighting the bike's performance and suggesting that 15-20 miles can be achieved depending on factors such as weight.
good idea for a basic conversion, but I would suggest that you fit a adjustable hinge on the display so that you can easily see the display all the times when riding will be a great improvement on the one your are promoting you will out do the swytch bike system totally
Feature request for gen2, would it be possible to charge with usb c power delivery? You could then use any modern laptop charger at the office to top it up while you're there which would reduce range fears for commuters without need to carry a charger which would be nice 😊 I'm a 100kg+ rider and it's hilly around here.
15-20 miles is about the max commuting distance on a bike I'd reckon(anything more will just take too much time) Slap some saddle bags on the back, bring ur charger to work and you're good to return home.
Seems to be on a par, range-wise, with the Swytch gen 3, but not as good as my gen 2 which I can get a least 30 miles from. Will be interesting to see if delivery times and customer service are any better than Swytch.
You know what be good on that design is a pop up display you can see well riding the bike and see how much range you have lefted without having to lean over the handlebars to see the display or get off the bike
@@andykirby Maybe they should integrate bluetooth and an app to display on an iWatch. Better yet, a simple clear piece of glass to project on like a automotive HUD.
Be good to have a second kit with a rear wheel keeping the red light for the rear or carrier and the white light for the front kit so you always have a back up
I do the low gear thing commuting home from work. This is a great looking bit of kit. I've always wondered why their aren't more of these kits about. Particularly batteries with in built controllers. I'd love to see a similar kit to this but mid drive. With under saddle mounted battery.
Iv'e always thought that if wheels are turning you should be able to recharge the battery while in motion. Bikes, cars, whatever. There might be a way to use the pedals somehow? If I could figure something out to do this, I would donate it to the public so it would be free energy.
That track playing, is that Hellen on the vocals? It might be a good idea to do a teardown of the hub motor, I've had a Swytch motor and the outer ring gear is plastic, I've had to 3d print a new one, even at that, I'm looking to cast one out of metal. Just interested to see the build quality on the gears?
I’ve got an old Electra Rat Rod cruiser that I’d love to put one of these on, it’s very heavy but it rolls like a train, when you get it up to speed it just rolls with very little effort at all and just keeps going. I reckon this would be ideal.
I really need one of these, after having a seizure and ending up in a canal in my land rover am now on 2 wheels only ( and just 1 when I can on my Unicycle, honest) but this is something I can afford and use daily. I also live on a boat so was embarrassing but have towpaths to go down like you.

@@andykirby this is a game changer and can switch my bike back to "normal" mode when I want to go out for exercise and don't mind getting sweaty. I'll keep an eye on your site for when it's available. Cheers dude 🙂
That's all well and good, but you only really need the assist uphill. Where I live in Sheffield its down hill in every direction going out but steep uphill all the way back when you need it. So I'd need 7 miles of uphill power. It's steep and I'm 98kg, would it do it??
You could glue neodimium magnets round a rim and an array of coils along a mudguard to generate power from the downhill, and maybe have the mudguard able to move up away from the mag field on the uphill so no drag. Oops, been watching too much Robert Murray Smith . . .
I have a 26'' wheel folding Dahon Jack. I fold it for the train everyday but take the handlebars off the stem using an Allan key. Could I still do this with your unit? (battery off, of course). Thanks.
can the mk2 version have an external battery socket so we can plug in for extra range... I live in mountains and i find it a worry that someone obese won´t be able to pedal up the mountain without a spare

Internal resistance of a Lithium Ion battery decreases with heat which allows electrons to flow in and out of the battery faster...BUT they can overheat and that's when bad things can happen like thermal runaway. They generally work better when warm vs cold.

I see your point but this is more about commuting. If you want to get to work or do an errand without getting sweaty or taking the car then ebikes are useful.
FyldeFlyer. You are right of course, but health issues affect some people. I finally added a friction drive e-assist kit to my road bike when I hit 90 and the hills got a bit much. The hills are OK now, but I still get a good work out, depeding on the length and gradient
I don't think the BMS in my bike will allow you to flatten the cells down to 3.3 volts per cell....🤔🤔😳🇬🇧 I wouldn't like to push them that low TBH Chinese cells and BMS suicide is a well known phenomenon...🤔😳🇬🇧
I'm guessing its based around 3500mAh cells, 2 in parallel and 10 in series to give you 20 cells in total. This is quite a common configuration for ebikes and e-scooters. It's not a huge range but still a very usable range for most people. It would be more efficient with a throttle though so you only use power when you need it. Perfectly legal in the UK to have a throttle on an ebike kit. Department for Transport made a statement some years ago stating throttles were legal on ebike kits.
Close to 19 miles isn't that bad considering it's such a small battery but it also ruins the point of getting an Ebike in the first place when you only get like 20 miles of range. That is just absolutely useless in my eyes.
My round trip commute would be around 15 miles and can charge at the office as this thing is so small so it could do a 30 mile round trip in theory. Just need charging times and how big is the charger answering. Leaving a charger at work could be an option as well. I think it looks ace myself for commuting.
Not really, This thing is perfect for people who live like 5-8 miles away from their workplace. could easily ride in full power each way without running it flat.

Is it necessary for the battery pack to be pointing downwards? It looks odd, like it should be facing straight forward…

Great piece of kit, would you be able to deliver to Australia?

Does the front light do much or why not angle the box higher so you can see the panel?
In reality you wouldn't be using assist along a tow path thats flat, so distance can be much more if you only use it when needed😊

An effortless 20 miles is something. I'd like to see a test with minimal assist, rather than pushing it to the limit
