The only one of its kind, this is the tandem electric bicycle that assists riders up to 20 mph in relaxed comfort. A 500-watt electric motor drives the rear wheel to assist riders up hills or across broad flats for easy cruising. A twist of the right handlebar controls the motor's variable speed while a push of the thumb changes the six gears; pedaling will increase speed further than 20 mph. Its step-through design provides easy mounting and dismounting for both riders. Two generously padded triangle seats with adjustable suspension and 26" Kevlar-lined balloon tires provide soft yet stable journeys. The two sets of padded wrap-around handlebars provide relaxed, upright riding. Front disc brakes and rear hub brakes are controlled by the front rider. A full charge of its detachable 48-volt lithium battery from its portable AC charger provides up to 25-mile journeys (depending upon rider weight and terrain). Sturdy aircraft aluminum frame supports two riders up to 500 lbs. Minor assembly required. 104" L x 13" W x 44" H. (67 lbs.)
