Custom built Felt MP cruiser bike. Ezee 26" v2 rear hub motor (250rpm) powered by a 50v 20 amp Lifepo4 (A123) battery. Safe battery chemistry for safe charging. Thumb throttle, cycle analyst, 58.4v 5amp battery charger. Fast and heavy bike, so I had custom disc brakes professionally TIG welded to the frame. No pedal assist required, will pull me from a stand still up a hill with no assist. Built the bike and never really used it.
