Students created an electric bike Ethec with a power reserve of 400 km

Students at the University of Zurich in Switzerland developed a prototype of an electric motorcycle with batteries for 15 kilowatt hours

Students at the University of Zurich in Switzerland developed an electric motorcycle called Ethec. The device is capable of driving without recharging batteries up to 400 kilometers.

13 students specializing in mechanics and one electrical engineer worked on the novelty. Ethec received the main engine on the rear wheel and another auxiliary unit on the front, responsible for the recovery of kinetic energy during braking.

The electric motor is powered by a 15 kWh lithium-ion battery pack, which can be fully recharged in about an hour using a special quick-charge system. The main unit is cooled by the thermoelectric system, and the batteries have oil cooling.

Despite the futuristic appearance, Ethec has a design peculiar to classic motorcycles. The device received a lightweight tubular frame, a “swingarm” (pendulum of the rear suspension type “softtail”), and a trapezoidal plug in front.

At the moment, the development of electric motorcycles leads several large companies. For example, Harley Davidson intends to present such a serial device in 2019. The American firm has been working on the “green” bike for the past five years.

The first prototype of Harley Davidson showed in 2014. The concept was completed with an electric motor that produces 74 hp and 52 Nm of torque. The unit allows to accelerate from a place to 100 km / h in about four seconds, and its maximum speed is limited to 150 km per hour. Electric motorcycle The stock of accumulators is enough for about 85 km of run. Fully recharge the batteries can be in 30-60 minutes.
