History of the Quantya EVO1 Track
Quantya S.A. was founded in 2005 by the entrepreneur Claudio Dick and worked on the development and production of sport electric motorcycles. The company was based in Paradiso, part of Lugano in the Italian-speaking part of Switzerland. Its most important product was the electric motocross bike Quantya EVO1 Track, from which a road-legal version, the EVO1 Strada, was derived.
The Track was designed as a competition-style dirt bike. The motor, supplied from England, is an axial-gap DC brush motor with a maximum output of 12 kW, equal to 16.3 hp, and a maximum torque of 31.5 Nm. It drives the rear wheel through a toothed belt and a chain. The motor controller came from the American company Alltrax Inc.
The battery is a 48-volt lithium-polymer pack from the South Korean supplier Kokam. About the size of a reserve fuel can, it weighs 19 kg and stores roughly 2.3 kilowatt-hours. A full charge takes two hours and gives a riding time of between 30 and 180 minutes, depending on how the bike is used.
Design and features
- Light weight: the complete bike weighs 92 kg, which the 12 kW motor has to move together with the rider.
- Swappable-style battery pack: a 19 kg, 48-volt Kokam lithium-polymer unit of about 2.3 kWh.
- Long running time for its class: two hours of charging give 30 to 180 minutes of riding.
- Motorcycle running gear: 19-inch front and 18-inch rear wheels with 245 and 270 mm of travel, and two hand brake levers working single-piston disc brakes.
- Running costs: a full charge cost 40 to 50 cents for the energy, plus about 200 cents set aside for the battery, roughly 2,000 euro per 1,000 charges.
