Pedal Powered World, #6: Power Generation

Bikes Energy & Sustainability Fun & Games

This is part 6 of an ~8-part series I’m doing on bike-powered devices. If you’ve got a link to another device that should be included or a better-documented version of any of these, comment below or email me and I’ll add it to my last post in the series, summarizing all the interesting pedal-powered projects we’ve found by category. I learned about most of these devices through the old-news Innovate or Die contest.

These designs product power. Suspension scavenger is neat to me because it’s not creating resistance to your forward motion: you’re just using energy that’s wasted bouncing up and down:

Also shift into:

What’s the most efficient bike electricity generator design you can find?

    Where does the energy dissipated in the suspension fork come from? Oh right, it comes from pedaling. Which is why people who really care about losing propulsion efficiency on a bike don’t have bikes with suspensions in the first place. But if you’re stuck with a springy fork, this is a cool way of dumping the extra motion into batteries instead of heating up the fork.
