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.

Special thanks to Sina for the tip!


  1. LOVE IT! – We had some similar ideas recently for this same project (beaten to it! – Good Job). Might still have to do one as there is one more step needed. – Cycle power with paddle attachment on rear wheel – No additional motor required.

    Still have one another secret project for the Xtracycle in the works. 🙂
