I built one of these a few years back for an engineering competition -- the only rules were the kart had to be electric and fit into a 2' cube. Funny video.
That looked like great fun Ed
Which one was yours?
Unfortunately, mine was still unfinished at that point, so its not in the video.
By the time it was done, it weighed about 120 lbs, had a 4HP motor on it, a speed controller from a forklift, and pulled over 200A at 24v under full throttle. Top speed was ~ 40 mph.
Oh, and it liked to dump you on your behind. No room in that cube for wheelie bars, and the center of gravity is, well, not optimal.
