Is there a way to change this?

Good morning everyone! When I set the assist level on my TSDZ2 to maximum and turn off the bike, the next time I turn it on again, it will be on ECO. Is there a way to always have it on maximum assist when turning it on? TYVM in advance!

Oh, and does anyone know what happens if I buy a battery from pswpower, unitpackpower or any other chinese company, install it on a customer's bike and the battery goes up in flames over the course of the years? How would the liability situation look like?

Well, unfortunately I don't have any formal qualifications in electronics or as a mechanic. All of my knowledge comes from forums, youtube and years of tinkering. I'm fairly confident that my batteries are on the same level as the batteries that I've bought in china and the UK - but proving that...

Thank you for your insight, Mr @Woosh I'm aware of the cost of the components and they are fine with me. One big advantage of building them myself would be next-day availability instead of waiting for weeks. I'm not in the position to have dozens of batteries in a local warehouse. I also will...

Hey guys. Over the last year, I've done 10+ ebike conversions and built the batteries myself every time, so I have a small bit of experience. I recently met the owner of a bike shop and he is impressed by the value for money of my ebike-conversions and asked me if I would be willing to do...

Just in case you missed it on the website: The G060 is a fatbike motor with a much wider axle than 135mm and won't fit most frames. If you're already aware of that, then never mind :)

And I would have to pay courier motorcycle insurance, which would be the same price as one new hub motor per month.

I was under the assumption that hub motors would last much longer if I replace the nylon gears every 5000km or so. I can replace them myself and also lace hub motors into rims, so that would not cause any additional costs. I live in Brighton, which is very hilly. I'm a bit concerned that a 250W...

Yes, 90USD for the motor + 85USD shipping, if you order a single motor. Would definitely be going for the CST (cassette) version. I'm using 11-42 10 speed cassettes on all my bikes and there isn't anything comparable as a screw-on freewheel.

Btw, Bonnie from Xiongda would happily send me a YTW-05 with "250W" laser engraving.

Does anyone know how the G040.250.DC compares to the Bafang CST? https://www.bafang-e.com/oem-area/components/component/motor/rm-g040250dc/ I've read something along "G040 (formerly CST)" several times on aliexpress.

I found that out after burning through several sets of them (and they are quite expensive and rather hard to find). The G310 is a really nice and quiet, but really not durable enough for my usage.

Thank you, your input was very helpful. Is the gear reduction ratio of any importance here? (The G310 runs at 1:11) I've tried to find the Bafanc CST with a 250W label for quite a while now - with no success so far. If anyone has a source, I'd be all ears! Could you let me know which 250W...

I've seen that one on the Bafang OEM website, but never found a website that actually sells the 250W G040 version. Asked 2 sellers on alibaba, but their response was rather confusing. Regarding the nylon cogs: The G310 uses non-standard nylon gears that look like this:

Hello everyone! At the moment, my main job is to deliver food on my DIY ebike and I usually ride 80+ miles, 6-7 days a week in a rather hilly town (Brighton). I'm currently using a Bafang G310 rear hub motor, but it's not really up to the task and I have to replace the internal nylon gears...

Hey everyone. My Bafang G310 has 6 screws that hold the cover plate in place and over the course of 6 months, I stripped 4 of the 6 threads. The screws are fine, but the threads in the motor hoursing just don't grip any more. Any advice how I can fix this? TYVM in advance!

My concern is that the same thing might happen again. The hose clamp attachment sounds much more secure.

I'm looking for an alternative to Grin's Triple Bob downtube hose clamp battery mount with UK/EU availability, since shipping fees from Canada to England are 33USD. https://www.ebikes.ca/shop/electric-bicycle-parts/battery-accessories/triple-bob.html# Last week my bike fell over and the...

Thank you very much, Nealh! Great find! Which one of the cells (preferably 18650) would you pick for a 250W 10s9p system that's optimised for capacity and cycle life? I would have picked the MJ1 again, but WheezyRider's comment regarding internal resitace made me a little nervous.
