Cyclists are already doing their bit to help the environment by eschewing a fossil-fuel guzzling transport option. Now they can do a little bit more using Nokia’s newly unveiled Bicycle Charger Kit which lets cyclists charge their mobile phone using pedal power. The kit employs a bottle dynamo that is driven when in contact with the front wheel like those found on ye olde time bicycle lights.
Charging times will obviously vary depending on the phone and cycling speeds, but Nokia says cycling for 20 minutes at 20 kmh (12.4 mph) will power up a Nokia 1202 for around one hour of talk time, or 74 hours of standby time. Charging starts when the cyclist hits walking speed, or around 6 km/h (3.7 mph), and at 12 km/h (7.4 mph) it will charge your phone as efficiently as a mains charger. And there’s no need to worry about going to fast and sending a power spike to your phone as the charger will cut out if you somehow exceed 50 km/h (31 mph).
