The Quadraped is a unique trike. It has both hand and foot cranks, providing for a whole body workout.
A mid-drive gears the power from the hand and foot cranks and connects that chain to another cassette on the rear wheel. Both shifters are mounted beside the mid-drive.
The Quadraped has tiller steering, with a gas-filled damper attached to the two tie rods.
Both drum brakes are controlled by a single lever, mounted on the left side of the frame, opposite the shifters.
This Quadraped was even equipped with a gas engine, which I promptly removed.
I got the Quadraped in pieces, with some missing, so right I immediately began restoring it.
