They weigh about twice what a non motorized one weighs. I believe most of them cut off power at 22mph. No recharging while coasting on any that I have seen. From what I understand the recharging mechanism adds too much weight. They are still pretty expensive starting around $2500 for basic bikes - ~ $750 std. mt. bike comparable components and fork. They had a $10K model at the Trek dealer a few weeks ago. Awesome - as it should be. Hopefully trickle down tech will work its way into E-Bikes by the time I need one.
