Scientists at Massachusetts Institute of Technology (MIT) are testing a new electric caster hub that appearance a wireless, alien ascendancy burke that works by Bluetooth technology.
The abstruse to the GreenWheel electric motor is that it is little beyond than a bicycle’s accepted hub and as a aftereffect can be adapted to the rear caster of about any accepted bicycle.
Unlike other ‘retro fit’ electric bicycle motors, the GreenWheel has no wiring to fit – the throttle, which attaches to the handlebars, uses the same Bluetooth technology used in many mobile phones in order to control the electric bikes‘ motor.
The GreenWheel is advised to bear 25 afar of pedal-free riding, and this can be continued to 50 if the addition does some of the pedalling. The battery is intended to last for 40,000 miles.
The array can be answerable by pedalling, or by active the caster into a mains electrical accumulation for 15 minutes.
A agent for the Environmental Transport Association (ETA) said: “Electrically-assisted bike accomplish faculty for those who are clumsy or afraid to ride accepted bikes, but the key to their success lies in them acceptable added affordable.”
The GreenWheel electric motor is currently ability testing and no retail amount has been announced.
The recently unveiled high-performance electric sports cars like the Tesla Roadster may do best at stealing headlines, but it is the relatively humble electrically-assisted bicycle that is likely to do more in the fight against climate change.
The rider of the recently-launched Schwinn Tailwind electric bike needs to pedal in order for the battery and electric motor to help propel the bike, which makes it more efficient than ‘battery power only’ models.
A spokesperson for the Environmental Transport Association (ETA) said: “For those unable or unwilling to ride conventional bicycles, battery-assist provides a relatively green and healthy alternative to almost every other type of transport.”
