MIT SENSEable lab have introduced a revolution in electronic bikes, in the form of the Copenhagen Wheel.
The gadget essentially replaces your bikes back wheel with an alternative which has a distinctive hub at the centre. Within this hub is a great piece of technology, turning your bike into an eclectic bike. It utilises the energy dissipated whilst cycling and braking and stores that for when it’s needed most on your cycle.
From the official site They state:
There is no external wiring or bulky battery packs,
making it retrofittable into any bike. Inside the hub, we have arranged a motor, 3-speed internal hub gear, batteries, a torque sensor, GPRS and a sensor kit that monitors CO, NOx, noise (db), relative humidity and temperature. In the future,
you will be able to spec out your wheel according to your riding habits and needs.
Major plus points are, as described above, the integration of the sensor unit, allowing easy integration with your iPhone, showing things you would usually expect from a cycle compute, but also sensing things such as carbon monoxide etc. excellent for the health conscious commuter! And also the lack of external battery pack, this is all within the hub.
I imagine this type of hub could catch on, here’s hoping the design is finessed somewhat.
