First Ebike project
first ebike project
An old pushy with a 1000 watt 48 volt 700c rear wheel motor kit
Manual 180mm disc brake.
Had to make a mount bracket for the rear disk brake.
the stock wheel caliper brake on the front.
Have also added lights and directional blinkers made from wheel reflectors and (blinking) LED's powered by a separate little 9v battery
Am working on integrating a rear brake light.
Lots of torque, can do 65kph but regulated to 35kph because of instability due to the battery mounted too high, poor braking.
Other problem was with the peddle assist lead from the motor controller being too short and couldn't mount the magnetic pickup rotor on the one piece crank.
Has done 300km over 18 months just riding to the shops.
Security: Battery has a locking mechanism built in.
Hardened chain with crypto padlock (make them work for it)
Pro's: around 15 km (without pedal assist) per charge depending on terrain, no parking problems,
Con's: no suspension (some of the footpaths are really rough around here).
Rear spokes need regular tensioning and weight of Ni cad battery pack combined with being mounted too high,
It's the only practical place for this type of bike frame, tried to mount it lower down between the pedals but it was still a bit too wide on the narrow side.
