This bike generator design is good for running low power devices such as:
- An iPOD
through a 12V Car cigarette lighter adapter like this one
- Cell phone chargers
- Portable DVD player
You can use off the shelf parts from local stores to make this 296 Watt pedal power bicycle generator or buy parts from Amazon.com
Through volunteer efforts, 24 of these pedal power bicycle generators were assembled and used for charging cell phones at a 3 day event with 60,000 people attending a day. More Info here
Any one who can use a drill, socket wrench, hack saw, wire cutters, and crimpers can do this project.
