Good used TerraTrike Rover Tandem with powerful Bafang Electric Assist and dual batteries.  The Rover frame is higher for ease of entry/exit, and the adjustable seat backs make for a comfortable ride. Independent pedaling allows either the captain, stoker, or both to pedal or rest.  Enviolo continuous variable transmission rear hub makes for smooth shifting, and the dual front disc brakes make for positive stopping.  Also included are dual mirrors for both the captain and the stocker and an over-the-seat storage bag.  Standard pedals with clips/flat for biking shoes or tennis shoes are included.  This is a great recreational tandem trike!
