HELSINKI: Want to talk more? Keep pedaling, says Nokia.

The world's largest mobile phone maker on Thursday launched four low-priced handsets and a recharger that can be connected to a bicycle's dynamo which charges when the wheels turn.

The bicycle charger kit and handsets - some with a standby battery time of up to six weeks, FM radio and flashlights - are aimed at users with limited access to electricity.

The new devices will be available during the second half of the year, priced at between 30 and 45 euro ($36-$55).

The bike kit has a charger, dynamo and a holder to secure the phone to the bicycle. The dynamo - a small electrical generator - uses the movement of the wheels to charge the handset through a standard 2mm charging jack used in most Nokia handsets.

It cuts off at speeds lower than 6 kilometer per hour and higher than 50 kilometer per hour.

The price of the kit in emerging markets starts at 15 euro ($18), and likely will cost more in other markets, Nokia said.
