If this thing works as advertised it could get a lot of people pretty charged up. (Sorry, that was some dynamo humor.)
Anyway, Bike2Power has released a hub-mounted dynamo that can be used on nearly any existing bike, has a built-in light, and can charge USB devices. Unlike some similar devices that require a dedicated dynamo hub, the BikeCharge Dynamo can be installed on almost any front or rear wheel and the lights can be set to high, low or blinking modes.
By cacheing the power in a 1,100 mAh battery pack, it can charge devices like smartphones, which are notoriously picky about power draw. The battery means it will continue to power your device even when the bike is stopped, such as at a red light, without interruption.
I predict these types of devices are going to be big in the next few years as more touring and city cyclists want to bring their gadgets with them. I’m also intrigued because it will fit on fat bikes with extra-wide front hubs
At $119 it’s a lot less expensive than a dynamo wheel, and can be switched from bike to bike. The best part is that if it doesn’t fit your bike, they will even take it back for a full refund within 30 days.
We’re going to try and get our hands on one to review, so stay tuned.
An earlier version of this story stated that there are no dynamo hubs available to fit fat bikes. However, the Son 28 135 is in fact available to fit fat bike forks with “rear” rotor spacing.Tweet Print
