Right now in the u.s. the electric bicycle market is infinitesimal, but my crystal ball sees a perfect storm brewing on the horizon. Fueling this perfect storm is a confluence of factors quietly happening almost unnoticed to the untrained eye. For starters there's a federal initiative...

Some where I read of adding capacitors to SLA batteries to improve performance. Would some one explain the advantage ,what caps to use, wiring, etc. Thanks!

I think we've reached the beginning of the electric vehicle revolution. It started almost unnoticed with Chevy Volt's. Actually I think the real beginning was started by cell phones, and lap tops. They taught us we could use our electric stuff by day, and charge at night. That lead the way for...

Why would anyone buy an electric bicycle for $1,500-2000 when they could buy a nice store bought gas powered bicycle for around $600 or 700? Or if they felt so inclined they could spend $1,500 and get a really great gas powered bicycle. Legal issues? That's the only reason I can think of.
