Concept
How to Build the Pedal-Powered Electricity Generator
Step 1: Connect the bicycle rear with the chair.
Use an adjustable pole if you want to adjust the pedal powered generator to different leg length.
Use a socket to provide more portability.
Do not weld directly onto the crank housing.
The final crank position should be a couple of inches above the seat.
Step 2: The base for the generator.
The generator will be placed on the bottom in the front of the wheel and its base can be made of office chair parts.
Step 3: Generator belt
The wheel shown in the picture above is a 26 inch one. To fit the generator between the wheel and the ground a A78 (78 inch circumference) belt was used.
