Overview
Introducing the 2020 Johammer J1, a pioneering electric motorcycle that embodies the future of two-wheeled mobility. As a prototype-concept model, the J1 stands out in a rapidly evolving market, offering a unique blend of innovative engineering and striking aesthetics. Priced at €22,900, this bike is designed for riders seeking an eco-friendly alternative without compromising on performance or style. Available in a variety of eye-catching colors, including silver, white, blue, green, and yellow, the J1 is more than just a motorcycle; it's a statement about sustainable riding in the modern age. At the heart of the Johammer J1 lies a robust DC-excited synchronous motor that delivers 21.5 horsepower (15.7 kW). This powerful electric motor is paired with a single-stage transmission, which is submerged in a sealed oil bath, eliminating the need for maintenance and ensuring a worry-free ride. With a top speed of 120 km/h (74.6 mph) and efficient air cooling, the J1 promises a thrilling yet smooth experience. One of its standout features is the regenerative braking system, which not only enhances safety but also extends the bike’s range by harnessing energy during deceleration. Weighing in at 178 kg (392.4 pounds), the J1 showcases a commendable power-to-weight ratio of 0.1206 HP/kg, making it an agile companion on urban streets and winding roads alike. The Johammer J1 is replete with features that highlight its cutting-edge technology. The central aluminum frame is both lightweight and sturdy, ensuring excellent handling and stability. The front and rear suspension systems utilize progressive suspension control, enabling a comfortable ride even over rough terrain. With a seat height of just 650 mm (25.6 inches), adjustable for the best fit, the J1 is accessible to riders of varying heights. A 72V lithium-ion battery provides an impressive range of up to 200 km on a single charge, with a full charge taking just 3.5 hours, making it practical for daily commutes or leisurely weekend rides. **
