The Amphibious Xtracycle was created by adding pontoons to a long-tail Xtracycle electric cargo bike. The pontoon frames were fashioned from conduit and pivot up/down on four BMX stems. The front float is an inner tube. A trolling motor is mounted on the back of the bike that utilizes the same batteries as the bike’s motor.
Top Speed: 20 mph land, 4mph water.
Claimed Weights: bike 40 lbs, motor and battery 40 lbs, aquatic parts 40 lbs. Total 120 lbs.
