This should have been one of the very first posts though... anyway so many things are not in sequence here...

My first experiments with electrical propulsion started off the e-bicycles. I got a kit from china and converted a normal geared bicycle into electric. My Prof kindly approved this in return for engaging some undergraduate students in projects which would count towards their final degree. Hub motors are so cool, they eliminate the need for a transmission from motor to wheels and it really, its much less hassle.

This was the first attempt at electrifying the bicycle, i got 3 12Ah SLA batteries each weighing 4kg somehow attached to the frame. 12Kg hanging from the frame, wires flying here and there hooking up the controller in the rear carriage and i still managed to get an "EV grin" when i twisted the throttle and it zoomed uphill without e
ven pedalling.
