The Copenhagen Wheel, unveiled by MIT students at the COP15 Climate
Change Conference, may not look like anything special. But in reality,
it’s a treasure trove of bicycle wheel technology, complete with a
kinetic energy recovery system (KERS), sensors, a smart lock, and a
Bluetooth connection to the rider’s iPhone.
The KERS system is activated when the user brakes. Energy from the
braking action is stored in the wheel, where it can be recovered by an
electric motor for later use. The wheel’s onboard sensors monitor bike
speed, distance traveled, direction, pollution levels, and proximity
of friends on the road. All info collected by the sensors is sent via
Bluetooth to the rider’s iPhone, which can be mounted on the
handlebars for easy access.
Worried about using such a high-tech wheel in theft-prone cities? The
Copenhagen Wheel’s smart lock sends a text message to users if someone
tries to steal the bike, greatly decreasing the likelihood of a
successful theft.
The wheel is expected to go into production next year at a price
comparable to that of standard electric bikes. The city of Copenhagen
might even use bikes retrofitted with the wheel as a substitute for
city employee cars — a lofty goal, but one that could help Copenhagen
become the world’s first carbon-neutral capital city by 2025.
