I've ridden it to work and back (11.2 miles each way) for the past three days. Until I get my BMS working, I'm charging it when at work and at home.
Acceleration is good, but It draws 250 amps on hard acceleration. It takes 60 amps to cruise at 48 mph.
Great job on the build.... awesome project. Why did you cut the tank like that? to swap batteries easily?
what is your front/rear sprocket ratio? I'm at 4:1, and ordering a 60tooth rear so I can do 5:1.
Is that 250A on the battery side or motor side?
My EM hits ~80A on Battery side at 72V, but I get 350A on the motor side under heave acceleration, with a 6.7" ADC motor, custom Synkromotive controller and that 4:1 ratio. We topped out at 63 or so (see my evfr http://www.youtube.com/frodus17
Keep some cooling on that motor. Does it have a built in fan? Thats the great thing about 6/7" motors, they've got a fan in the shaft output end that sucks from the brushes, through the field windings and out the face.
