That sounds like an awesome little bike! What is your pack voltage and controller? Were you able to put a sprocket on the shaft of the 1000w motor?

Hello people, I am thinking of building a medium-powered (30-35mph) honda ct-70 conversion using this motor, but I'm having a hard time finding good information or builds using it. The other motors in this 'family' - the qs 120 2kw and qs 138 3kw motor all seem to be very underrated in terms of...

This looks like an awesome project. Keep up the great work, I would definitely be interested if you started selling these.

A mighty mini does look tempting, especially with the decrease in complexity and peace of mind compared to lipo. Does anybody have opinions on This 7.8Ah 48v pack made from 20R cells? For the price of $200 it seems like a steal. https://em3ev.com/shop/preditor-l-47v-8-4ah-11-8ah-frame-battery/

What does your LiFePO4 pack consist of?

I am planning on implementing a mid-mounted motor so I can retain use of the rear cassette, so hopefully that will help with my motor's flexibility/hill climbing? Thank you for the link, I am playing with it now. I think this will definitely help me understand the power requirements for my use case.

Yes, weight was the other problem I thought I would run into, but I was not too concerned by it with a small Ah pack. I found your system interesting, I have not come across the battery medics before, and they look like a good cheap option. So if I understand correctly, you use the battery...

Hmmmm... I see, the problem with adding more capacity is my costs will dramatically increase. I suppose I will do more research on LiPo.. Realistically, I doubt that I will use 30A for more than a couple minutes at a time, although this would be my first e-bike, so I am unsure what typical loads...

Hello, I am looking to build an e-bike to get me to and from class (2 miles, some somewhat serious hills). I have the controller/motor setup planned, but want some opinions on battery choice. I have been reading a lot, and am a little nervous about LiPo chemistry, as I have no experience with...
