Thanks to greenIT.fr for highlighting the availability of the ‘Bicycle Charger Kit’ from Nokia (which charges your phone, not the bike’!). It’s a sign of the times that you can now charge your (Nokia) mobile phone while taking the most environmentally-friendly mode of transport.
There seems to have been some thought put into it. The phone mount is rubberised to minimise vibrations and the holder comes with a transparent bag to protect it from the elements. It’s compatible with all Nokia phones that have a 2mm charging interface and Nokia points out that the kit pays for itself through savings on charging costs (although I don’t know what the cost is).
The charger kicks in when the bicycle reaches 6 km/h and stops when (if?) your speed reaches 50 km/h. The total charging time varies, but Nokia gives the example that with 20 minutes of cycling at 10 km/h you can power up a Nokia 1202 for 1 hour of talk time or 74 hours of standby time.
It would be even better if you could carry it with you and easily clip it on to any bike, so for example, you could use it with the recently introduced free bike scheme in London. But the installation sounds too much for that. Maybe one day.
