This is one of the coolest bicycle accessories we have seen. The product from Reelight is a friction free bicycle light powered by Eddy currents, an energy generated without friction. This is cool because its essentially powered by the cyclist, converting the energy they produce from pedalling into electrical energy for the light. Talk about green and renewable energy, no need to buy batteries anymore.
This product is currently awaiting completion of their funding and they are almost there, with less than US $3500 to go. Check it out on it’s Kickstarter page.
