Maker Faire 2008: Electric motorcycles


Builder [Justin Gray] brought a pair of electric motorcycles to Maker Faire last weekend. Pictured above is the R84, which has 28 LiFePo cells and an 84v AC induction drive providing 54HP. All of that is stuffed in a 2000 Yamaha R1 frame. You can buy it now for $14,000.


The second bike is dubbed the R144. It’s a144v DC system with 48cell lithium power supply driving a 60kw series motor.

[Justin]‘s other passion is building fire robots like Libby pictured below.

    Did you get some pictures of ElectricMotorsport’s Todd Killin and his Electric R1?

    I didn’t go, but saw a ton of pictures of electric cycles.

    Very inspiring as I’m converting my VFR700 to electric.

    I can’t view Justin’s blog on his motorcycles. Can someone e-mail his motorcycle details to me please?
