Nokia has figured out how to make bike riding just that little bit more rewarding, launching a battery charger that recharges while you pedal.

The charger, which should sell for around $18, harnesses dynamo from your bike’s movement to generate enough power to keep your mobile on and will recharge all Nokia models with a 2mm jack.

But the pleasures of going green don’t come easy. To set the wheels in motion and begin charging, you have to be traveling at 6km per hour and then need to keep up a steady 10km per hour for 10 minutes to charge up to 28 minutes of environmentally-friendly talk time.

Not content to rest on their laurels, Nokia has also released four cheap handsets this week to accompany the new charger. These handsets are geared at users with limited electricity access and come with flashlights, FM radio and a battery lifespan of up to six weeks.

The cheapest of the new models (selling for around $30) will be available in the second half of next year and will be fitted with the company’s first two-in-one double SIM card solution. According to reps, that means you can switch between SIMs at a press of a button, avoiding those expensive phone bills when traveling between countries.
