Hi guys, I am a R.N. at the V.A hospital in Los Angeles. My ride is a Diamondback with Ampedbike enty level front hub motor kit. It had a SLA lead acid battery that worked o.k. for 1 year. I just bought a 48v 20 a.h. LifeP04 battery new but used. My other passion is tennis. Anyone 3.5 to 4.5 that wants to hit in the San Fernando Valley I'm available. (phone # removed by Mod).
