Electric Components
Motor

Rear wheel motor: 48 volts, 250 Watt (nominal). It has an engine torque of up to 58 Nm. It lets you easily carry loads of up to 170 kg. The torque and power values tell you how easily the bike will deal with certain difficulties (such as a hill). The motor is coupled to a torque sensor that provides electric assistance based on the force exerted on the pedals. It gives you a more pedalling motion.

Battery

Samsung lithium-ion battery 672 Wh (48V, 14Ah) Charge time = 4 hours 40 Battery range: 90 km maximum in mode (1), 70 km maximum in Normal mode (2), and 50 km maximum in Power mode (3) for someone weighing 80 kg on a relatively flat road with no load on the bike. NB: The battery life may vary depending on the weight being transported (rider weight + weight of any items being carried), the gradient (uphill) and the weather conditions.
