I've been wanting to bike the 12km to work, but it was a little too far. So I did what any respectable person would do, I cheated. More specifically I ordered an electric hub motor and battery directly from China and installed it on my bike. Overall a fun project, and the bike is a blast to ride.
Twist throttle on the right, cruise control control on the left and handlebar bag in the centre. I took apart an old speaker set I had and rebuilt it into a the bag. The clear patch allows me to control my IPhone through it.
Wiring that I had to shorten and put into this nifty box.
The motor and controller is inside the hub. Note the shape of the axles which allows for it to torque against the drop-outs. Pretty nifty idea.
