Imagine if you could multiply your muscle power via an electric motor when riding your bicycle – well now you can. Meet the ErockIT designed by German entrepreneur Stefan Gulas. The clever ErockIT design combines common bicycle handling (pedaling for acceleration, brake levers to the left and right of the handlebars) with the power of a motorcycle which allows cyclists to cover longer distances at much faster speeds.
The high 75Nm torque of the 8kW electric motor is fully available from first rotation and allows for great acceleration. Using a 12hp DC motor, the rotational movement of the crank assembly engages a permanent magnet generator that sends signals to the control electronics and recovers the energy produced through pedaling. This energy is then used for recharging the batteries. Lithium-Ion Nanophosphate batteries, with a 2.9kWh capacity, can charge in 3-4 hours.
Designed as an emissions-free alternative to motorcycles, the electric motor is coupled with the simplicity of the bicycle means the ErockIT is more accessible to a wider range of people and doesn’t require any special training or licenses to operate.
