Electric Scooter

In-house development of a complete powertrain for electric conversion of the conventional scooter Gilera runner ST 50 with the innovative GEM 4 kW electric in-wheel motor, produced in Slovenia. The motor is installed in the rear wheel of the scooter, which is equipped with high-performance and high-quality lithium batteries providing 80 km of range. With a standard charger, the battery is fully charged in less than 5 hours and with a fast charger in less than 2.5 hours. The battery life of 2000 cycles yields up to 10 years of use. Driving the scooter electric drive is about 10 times cheaper than driving a conventional gasoline scooter – the cost is only 0.30 € per 100 km.
