Ok., was flipping channels last night and came across "the green channel" or "planet green" or something like that. They had a guy that designed an electric dirtbike and had a competition againsts a yz250f. While the competition was bogus, the bike was pretty cool. It weighed 140lbs and looked like it was doing pretty good. Kinda cool, imagine being able to build a track in your backyard and the neighbors can't say a dang thing because you're not making any noise. It will be interesting as the technology develops
