BioLogic FreeCharge Empowers Green Bike Geeks!

In 2010 Dahon will introduce the BioLogic FreeCharge, an electricity storage battery that connects to a bike dyno hub. The BioLogic FreeCharge comes off the bike and can be carried around- it becomes stored electricity power that you can charge any device that uses a USB, from an iPod to a GPS unit.

The logic of the BioLogic is that it uses the inconsistent energy created by riding a bike to charge a small battery, then uses the battery to charge the iPod or other device. That means the FreeCharge comes as a steady stream of electricity.


Dahon plans to include the device on their new Ios XL and the Speed TR models. FreeCharge comes complete with a silicon casing for easy attachment to the bike. All sources say the BioLogic FreeCharge will be available next March for around $100.

Imagine a fleet of these at a bike ride fundraisers for green causes that then power the after-party? Or touring with one of these and not having to rely on café outlets or campground units- freedom. And as someone who puts a few miles a day on my own bike, I love concept of hanging onto some of that energy- and getting it from my own legs rather than from a coal-fired power plant out of the wall? Love it.

I look forward to further innovation with this kind of technology- knowing Dahon, I’m sure it’s not too far down the road.

    Awesome idea! I sent a link for this post to my bike geek bf who loves his bike. This would be perfect for him! I enjoyed reading your ideas for how this could be used. I don’t bike very much myself, but maybe I could get myself to do it for a fundraiser if I would get to go to the after party that I help power.
