I've had the Specialized Turbo Levo e-mountain bike for a few years now - absolutely love it. My local ski resort has a kick ass downhill bike park - what an adrenaline rush that can be. I don't do the crazy big jumps and drops, but catching a little air on it is a blast.
there was an electric mountain bike selling at a bike store downtown, think it was either $13,000 or $16,000. Teens who save their money nowadays have to decide between a high end ebike or a used car, prices are in the same range!
