If you spend a lot of time on your bike, you might want to consider putting some of that effort you’re expending to good use. Not that getting yourself from point A to B without needing to use a gasoline-powered vehicle isn’t a good use. But now you can also charge your Nokia phone while cruising the city streets.

Now pedal-powered charging devices might not be a new concept, but Nokia seems to have implemented the idea rather well with their DC-14 Bike Charger. Take, for instance, the fact that as long as you’re sustaining a speed of 8.7mph or more, you’ll actually be charging the phone at the same rate as if it were plugged into a wall socket. The charging unit is weather-resistant, so you won’t need to worry about it getting wet. Though you might not want to actually charge your phone in the rain. The phone itself will be strapped� down and secured to your phone with some handy straps. The device is currently on sale for around $40 in the UK. No word on a US release.
