This trike was built for a disabled person who can no longer pedal but still wants to have fun on his recumbent trike. Most of the trike’s drivetrain was removed and the left crank was rotated 180° so the feet can rest evenly. Several 3-D printed parts were designed to allow the battery to be mounted under the seat.


  • Catrike Speed.
  • Maxxix Hookworm tires.
  • 3D printed controller mounts and connector housing.


  • 72 V, 10 AH Lithium-Ion battery made from high C-rate Samsung 25R cells. Battery is good for about 20-25 miles at 25mph average speed.
  • Custom designed 3D printed battery box/platform to mount the battery under the seat.


  • 1000W DD hub motor.
  • 72V 45A sine wave controller.
