100 kW
Coming from my semi-serious 20 incher build, I wanted a bike that was more usable as a bike, more agile and nervous, but not neccesarly more powerfull.
I was seeing the limits of 20's and 250wh was not enougth when I got used to the 4kw peaks.
The 80-85 I had failed mecanically (phases shorting to the can... vibrations are a bitch) and killed one of my ss190-200 in the process. That's when I decided to take the whole bike apart and do something better
Solving the low end torque issue was one of the objectives, so i decided to go with a pocket bike clutch, and i found a very nice unit for only 25euros, that has a 1/5 #25 chain geardown!
I picked 16 headway cells back in december, I know those cells are far from perfect and way outdated compared to lipo, but as a RC guy I know how those can fail (don't ask me how )
With this bike i will use a 63-74 motor and a trustable ss190-200 on 8s2p, with the option to reconfigure for 16s1p and a sensorless ebike controller if I find one capable of reving this 180kv motor on 48+ volts.
Enuf talkin' :
I hope to get it runing soon, i still need to order a sproket adapter for the rear wheel and wire the pack and electronics.
Big plus to this build : removable from the bike in less than 5 minutes as motor and batts are one single unit!
