Well it definately isnt the fastest electirc bike in the world. The fastest at the moment that i know of is the "Killacycle" electric dragbike. 7.8 second 1/4 miles at 174mph, difinitively quicker than the ttxgp bike.

We're trying to develop and electrice bike for the ttxgp here at kingston uni, its quite a task to make one to do a 36 mile lap!
