An electric bike would be pretty cool. I like to shut off my bike and just coast downhill sometimes. Seem to see more critters in stealth mode. I'd be a little concerned about water crossings on an electric bike though, lol. When they make one with a 200 mile range I'd be a lot more interested.

Here's a few electric motos that look interesting.
