iPhone dead? How about some exercise!
While bike dynamos have been powering bicycle lights since the 80s, most modern bike lighting solutions operate on battery or solar power. But thanks to modern technology, it looks like the dynamo may be making its comeback, this time to power your gadgets. Created by iBikeConsole, the BikeCharge Dynamo is a compact, lightweight device that helps keep your USB gadgets charged. According to the company, the device is 20 percent lighter than traditional dynamo systems and can charge most smartphones in 2 to 3 hours. While most people won't be riding their bikes around for that long, the device is designed to add minimal drag while giving your connected device just enough juice to get by.
As an additional safety feature, the device also has front and rear LED lights that stay illuminated for up to two hours after riding thanks to a built in 700mAh Li-ion battery. Priced at $99, the BikeCharge Dynamo is a bit pricey for the casual biker, but for anyone who uses a bike as a primary mode of transportation, it may be a worthwhile investment.
