A Razor Scooter powered electric bike. Uses Friction Drive 3x12V SLA batteries on a direct circuit.

The bike was made at no cost as it is constructed from recycled parts. The frame was sourced from a scrapyard and had been in a crash. The parcel rack was also found. The motor was sourced from a kids Razor electric scooter and attatched to a pivot that was made using scrap steel. The bivot is attached to the brake arms. Batteries are from two different scooters that were thrown out.

On three semi-charged batteries the GPS Measured the bike as running at 20.78km/hr Max

This is an UNFINISHED School Project. I may post a step by step guide when I'm done.

For Now here is the picture.
I have the same scooter but the motor is so weak that it hardly moves. How do you get it to go on the bike? I don't see how it can move a bike and a person ?
Pedalling the bike up to a reasonable speed seems to make up for its lack of torque when starting. But i had to over-volt the motor to 36-45v using three batteries instead of two. You just have to make sure the wires are up to it as the motor seems to take it pretty well.<br>

Nice.<br> Looks similar to the <a href="http://www.camcycle.org.uk/newsletters/14/article20.html" rel="nofollow">Sinclair Zeta.</a><br> I'd love to see some more details and an 'ible.
wow. Never have actually seen that kit before, just designed it off the top of my head.
