What's so special about the bosch crandrive? Is it that so much more efficient than a hub motor?

I've been looking a long time for a good electric folding bike... until I realised none of them really answer my needs. Decide on the (non electric) folding bike that fits you the best, then convert it. You'll have the best electric bike :)

Not sure what it is lol. Can check that tomorrow :)

Yeaaaaah, I'm so thankful of all of you guys. Would never achieve that without all your help :)

Thanks. Going to see how I can enable regen :) Quick field report from today cycling: - I'm actually cycling slower than usual because I don't want to go too fast. Going fast on these small wheel seem dangerous. Some cyclist are faster than me, I think I'm taking too much precautions :lol...

yes, I'll be careful! Actually I don't know at what speed I'm running now, but I woudn't want to run any faster. The small tyres don't grip that well on the ground. I'm probably much slower than I think but with these small wheels it looks like I'm going so fast. I will do a report as soon as...

Here is the folded brompton: It rolls!!! :D It goes fast too. I don't have a speedometer on the brompton yet (as the cycle analyst plug wasn't compatible), but I think I'm around 25-30mph. :D Almost there. The controller is not that stealthy... I may put it inside the bag. Not...

Quick update on my brompton: - Purchased a spare 72V 45A controller from zenid: Zenid e-Bike Parts Received it within 2 days (in the UK). It doesn't have regen or can't be configured, but it's a very good spare controller. - Put my battery in a camera bag:

Thanks for the summary Flecc. These damn Conhismotor are really not reliable :(

They do not want to recognise anything: Me: "Ok, I can understand that I'm wrong. But can you explain me why I had a maximum distance of 27 km when I had my battery for the first month, and now I only have a maximum distance of 21 km?" Conhismotor: "Maybe you do not charge full electricity...

Thanks guys for the advice. I decided to test my battery today: - At home at 22 degree celcius - At full throttle no load which is equivalent to 2amps - Had a break after 2 hours to allow the battery and motor to rest. - Did 2 amps continuous until low voltage cutoff So it was the...

Before considering any kit, you should first check the dropout width of your rear and front dropout. If you have a dropout of 120mm (as for my Pacific if reach), you'll have very limited choice of motor.

The battery is about 6-7 months old. Just had an answer from Conhismotor: "I think you have some misunderstand in battery capacity, battery capacity only decide the lasting distance for one full charge, but not as your calculation 360-250=110W missing. For example 36V 7AH battery use for 36V...

yeah, but as rog said there is no way to check the initial capacity. I even opened the open to look at the cell individually and there was nothing written!!! I'm sure conhismotor is trying to con me lol

Yeah, just had the diagnostic from Lyen: The FET has burnt. Probably too much amps or wrong hall/phase sequence. Have to send back the controller for reparation :(

I know how much capacity is remaining (around 250wh). But I'd like to know what's the initial capacity of the batteries. They said it's a 7AH battery but I believe it was a 10AH battery.

Hello there, I'm now discussing with Conhismotor about my 36V10AH Limn2O4 battery that only has 250W remaining on the battery pack. So 2/3 of its capacity. The seller told me the pack was at 36V7AH so it's normal to only have 250wh of capacity. But I believe my pack is a 10AH rather than a...

Tom, Tonxing are good motor. But only for up to 15 mph. If you plan to go faster, you have to consider other motors.

22V6AH means 132wh capacity. Compared to the 37V9.6AH at 355wh it's almost a third of its capacity. So the price tag of the lightweight battery is even more expensive lol. Assuming their motor is good, you better get batteries from any other place than BionX.

How can a 360wh battery cost 1000£? For that price I can buy 5 NMC battery at 150-200£ that will have similar weight and last only 1 year but would have much better value lol
