Prices for low end Electric Bikes recently came down another notch, so I snapped one up.
It's fun, and really solves the problem of getting too hot when bicycling around town. You can let the electric motor do all the work on the way to a meeting, and arrive relatively fresh. It has pedals and a seven speed derailleur, so there is always the opportunity for exercise. The small 15-mile range has never been an issue, most bike trips are shorter than that. However, for $100, you can add a second battery to double the range, or to quick-swap batteries like a cordless drill.
