I had a long ride on one today, resulting in mixed feelings about the product. The advantages and disadvantages seemed to cancel out somehow, but maybe that is just me.
I've seen a few electric bicycles, but they're usually trikes. I love my CBR(600), but if I was going to get a litre bike, it would be an R1.
You can always peddle right? 16 miles is just enough to work up a good sweat.....
That electric mountain bike is an interesting idea. It looks like it's intended for actual trail riding, and I assume one would really only use the motor for assist on hills? I know some people with electric bicycles they use for commuting, but these guys are all pretty hardcore, with some serious money in their recumbents, and even a couple full on velo-mobiles. I had been looking into acquring a velo when I lived in the PNW for winter commuting, but once I moved back to AZ, that seemed extraneous. Should I start a derail on motorcycles? I could talk about those all day too. (I have 3 at the moment.)
