Been interested in building a diy e-bike for several years and finally pulled the trigger on an ebay special, branded as CSC conversion kit, 26" rear wheel 1500watts. I picked up a UPP Triangle battery 52V-20ah with 50A BMS to go along with it and a couple torque arms off amazon. I tuned up this 90s cro-moly steel Marin and got the kit installed. It all came together nicely and is a lot of fun
I was a little worried the bike would feel sketchy going the rated top speed of 50-60kmph, but the bike feels good cruising at the top speed. I was also worried that the v-brakes wouldn't be good enough but with new brake pads there is tons of stopping power and I can stop very fast if I want to.
I have to say I'm really happy with my first ebike, and of course I immediately need to try and make it better! I'm happy with the top speed (although I wouldn't complain if it went faster) but I'd really like to try and make it torquier. I don't really have a specific range that I am trying to achieve and want to make the ride fun first and foremost!
I'm thinking that upgrading the controller is a thing to consider. The display shows it pushing around 1600w on full throttle but not any more than that. My battery supposedly has a 50A BMS, and it seems like people get away with pushing a lot more than 1500w through these motors in short bursts anyways. The kit came with a generic "14 mosfet 35A controller" Can anyone recommend a good option for upgrading the controller? would the KT 18mosfet 45A controller be a good choice? square wave or sinewave?
From what I've read there are only a few dozen motor manufacturers that get rebranded by a hundred sellers, is there a way to identify what motor I have? Here are some pics if anyone can help shed some light. And is there a way to figure out how many turns this motor has? So far what I've read is more turns = more torque but also more heat.
The UPP battery seems good so far, and was a good value. The case is rugged and it came with a 4A charger. UPP told me that it contains Chinese 18650s at 2500mAh. So at 20Ah that would make this a 14s8p battery. To max out the 50A BMS the cells would need a discharge rate of 6.5A, I'll have to try and find out about that spec.
Any helpful information appreciated! Thanks!
