All depends on slope, time and weight... Still glad to see your progress

Time will show! Weight is 78 kg/170 lbs. The hills are quite steep here, but not that long. I guess gearing down with a larger wheel sprocket will make life easier for the motor. It will also make it safer for my kids when they want to try it -- this thing is starting to go blazingly fast!

I tested the 80T wheel sprocket now. WOW - this is fun!

It accelerates so fast I need to be careful on the throttle.

I have attached a Wattsup meter. I'm pulling peaks of 30A@48V... almost 1500W :-O

This poor 250W motor is working harder than I expected.

Ok, I stress tested it a bit more this weekend. I rode for some 45 minutes or so together with my daughter (total weight of 107 kg). The motor started smoking :-O

Conclusion: 12S is fine for one person short trips, but it's pushing the limits.
