Nerd-Cycle

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.

The batter gives me enough juice to go about 25 without pedalling at about 37km/h (45km/h if I pedal).

Does the battery recharge when you are going downhill, or pedaling? One of these passed me when I was out biking the other day (20km about Ramsey Lake). He had an easy time of it on the uphill, but I could catch him on the flats.

Have fun, and be careful about texting and biking at the same time.

Paul,

It does recharge when I brake. You could not catch up to me I promise (48V battery is not standard). I would also pedal like a mad-man to ensure that wouldn't happen...

Thanks for the comments everybody, we do read them and they keep us motivated to keep posting,
