Thanks to a suggestion I saw in the previous Electric Bike Poll post I went and looked the Killacycle! Check out their blog! Cool stuff! This is definitely an area where E-bikes can thrive. Short course racing. Drags, MX and even Supermoto. There’s actually a gap being closed in these areas. It’s when the distances stretch out that the competitive disadvantages of the E-bikes hit home hard. I’m surprise there isn’t a tials bike yet. The torque might be a natural and overcome the weight. I’ve even seen come cool videos on Electric go-cart racing that was badass. And quiet carts have the advantage that you don’t have to be out in the sticks with those tracks to hide the noise.
