So today im making about $800, and i want to start my ebike project!
Where i live, i'm about 10 miles from my school, and the speed limit is 45mph. I'm pretty sure i can charge it when i get to school also if the charger isnt too large. But, after all of my research, i've come across one problem. It is possible to get a bike going that fast, but the range is greatly decreased.
What i need:
10 miles range (minimum)
capable of going 45mph for 7 of those miles
has to meet safety standards to be registered as a motorcycle or scooter
My starting point:
A full suspension mountain bike with disc braking
A 48 volt 1000 watt motor kit form monster scooter parts
Turnigy Lipo batteries and connections from hobbyking
Charger from hobbyking
home fabricated battery and motor mounts
some meters to give me approx. speed
and i'll add lights and things like that later.
I want to do the gearing exactly like : http://www.youtube.com/watch?v=m8u0N2elaTk
although im not sure where to buy the tensioner he has mounted right next to the motor.
some suggestions would be great as well as some constructive criticism. if you think i should be starting with a motorcycle frame or something please let me know. thanks!
