This year our pedal power system is built on powerful hub generators rather than tire-rubbing generators.

Two-bike pedal power system.

The two-bike pedal power system shown above was our trusty backup system at Maker Faire this past weekend. Both bikes use powerful hub generators rated at far higher wattages than a human can generate. This means that we’re using them in a range at which they run cool, calm, and collected. They feel very smooth because there’s no friction involved. Just magnets and ball bearings.

Not shown this photo is the Biker Bar, Rock The Bike’s newest pedal power system. It’s got tremendous potential, but has had mechanicals at its first two outings. The plan is to fix the mechanical issues in the next 3 days, test it out at the Youth Unity Summit this Saturday, our last outing before BMF.

  1. [...] The new hub attachment translates into less power loss from the bicycle wheel to the generator than the previous power set-up. Courtesy, Bicycle Music Festival. [...]
