Nokia has unveiled a new method for charging mobile phones using the power generated by a bicycle.
The charging kit is specifically aimed at developing countries where bicycle usage is more widespread.
The kit will still use Nokia's conventional 2mm charger-jack and will keep charging a phone as long as the user keeps up a speed of more than 4mph.
Nokia Vice President Alex Lambeek stated: "Bicycles are the most widespread means of transport in many markets around the world, so this is just one more benefit to be gained from an activity people are already doing."
Along with the the launch of the charger kit, Nokia unveiled six new handsets with a standby time of up to 6 weeks, aimed at developing countries where electricity is in short supply.
A similar charger kit developed by Power & Pedal is already in the market, and Nokia's new addition is set to add to the growing eco-friendly industry.
The charging kit for bicycles will be available across the world by the end of this year.
