Building your own self-balancer only increases one's respect for Dean Kamen.

Looks interesting. Are you able to release any performance specifications? Such as range, weight, crusing speed, etc...

If the battery platform swiveled or hinged upwards, it might be compact enough to take on the bus. Might be kinda heavy though.

Haven't viewed the video yet, as I'm on dial-up right now.

I will want to give the specs when my new motor arrives. The current one was wound for speed not torque and expected pedal first assist that I overcame with gobbs of amps. The efficiency is dismal so I will wait to report when the specs are more impressive. This motor, however did confirm proof of concept, and does haul my 265lb 6'6" body around as shown in the video. SLAs kept the price down and the weight up!

So which half is it? ;)
