Re: What eBike kit to get for my Electra Townie 21D?

48v Ying Chen is the way to go. It only does 20mph but it gets there fast. It's an xofo cassette geared hub motor(comparable to a bafang bpm) and has a super nice LCD computer. They have 3 different prices depending on how long of a warranty you want. I opted for no warranty and couldn't be happier....

Re: What eBike kit to get for my Electra Townie 21D?

Hi and welcome to the forums! 1. If the 21d has from suspension then yes I would recommend a rear with at least 1 torque arm. I would use 2 because they're cheaper than a messed up frame or worse. 2. For 20 miles on a 1000w direct drive kit, a 15ah ping should be good. 20ah is better and worth it if...

Thoughts or Info on Brushless Gearless Mini Hub Motor CST

Hi, I wanted to post up and see if anyone has ordered or used one of these yet. I've seen the Bafang geared CST motors but this is the first time I've seen a direct drive CST compatible rear hub motor. I'm thinking of running it at 48v and possibly 40A (Hua Tong) on a hard tail MTB for offroad trail...

Help identifying small direct drive hub motor.

Hi, I picked up a bike off craigslist thinking it was a larger geared hub like a bafang BPM. I opened it up this morning and to my surprise it's a small direct drive. I couldn't believe my eyes. It's a front hub, no disk adapter, wires thru the axle, and has silver covers with some numbers and a cir...

Hi Deadmul3, Yes, I did get them hooked up. I just matched the color for color on the CON62 controller for both the hall sensors and the phase wires.

I just realized I never followed up on this one. The CON62 that I have does indeed work with the LED meter while not using the PAS. The sensor wires are required though. My wire colors match perfectly with a bafang, I think swxb. After getting my throttle wires matching, I found my second problem wa...

Re: Help with CON62 250w controller from greenbikekit.com

It sounds like your red wire in the throttle is shorted to the signal wire. Are you able to try a different throttle? Or, could you use a meter to see if they're shorted on the throttle you have?

Thank you for such a fast response Jimmie. And thank you for trying to deliver the accurate information.

Re: Bargain wheel set with nexus 8 speed & hub motor

My best guess based on the performance I'm getting is the Cute Q100 328r. The simulator shows that motor on a 700c wheel going 21.2 mph on 36v (12s) LiFe using a custom 14A controller. Real world using my RC watt meter and phone GPS with a 36v 12s LiFeP04 12ah battery I get right about 21-22mph with...

For whatever it's worth here's what I have to add and want to know about on this thread. Yes, LiFePo4 cells have some level of sag. If you put together a 12s pack and the operating voltage is 36v after sag, then you have a 36v pack. Why are you expecting a 41v pack with 12s? This doesn't make sense ...
