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.

All that time and expense for less than 19 miles range at 15mph?

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

Thinking of getting one of these kits for my homemade ebike so it could be AWD looks a great little conversion kit ✌👍

I'm impressed Andy

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?

Well done and good luck Andy - new subscriber... Havent really ridden a bike for 20 years or more.. This really got me excited.. Now I want to move to a country that doesn't rain all the time but hey ho, cant be too choosy :) _ I agree with comments on the other video, a screen you can see would be awesome and the ability for additional batteries would make it pretty cool... solar panel t-shirts next ?

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.

Being an e-bike rider, i value range the most. This looks like a good piece of kit.

Thats very good for such a small battery hauling 200lb rider. I was expecting 15 on the flat only.

Excellent music choice!

Who is singing on your music tracks there Andy? I love your music you now? The best from LB1NH 🙂

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.

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.

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.

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.

A fork that was not engineered for ebike will fail and you can get injured. You will not regret $15/torque arm to do this right. If you do not want to do anything to the fork then you can do a mid-drive conversion instead.
