How to Charge Any USB Device by Riding Your Bike

Step 5 Wiring

For the wiring from the motor to the circuit several options were considered: alligator clips for mock up, telephone cord, and speaker wire.
The alligator clips proved to work well for the mock up design and testing purposes but they were not stable enough for the final design.
The telephone wire proved fragile, and difficult to work with.
Speaker wire was tested due to its durability therefore becoming the conductor of choice. Although it was stranded wire, it was much more durable due to its larger diameter.

We then just attached the wire to the frame using zip-ties.
