Battery: What more could you want? The PowerTube 625 lets you enjoy long and mountainous rides, while still reserving plenty of energy for every adventure. Thanks to a rated capacity of 16.7 Ah and approx. 625 Wh energy content, the lithium-ion battery brings maximum ranges and altitudes within your grasp. The well-secured PowerTube 625 will not fall out of its housing, even on demanding terrain. But is still easily removed. After approx. 3.7 hours, the battery is fully charged with the 6 A Fast Charger, while half the charge is already attained after approx. 1.4 hours.

Display: Purion 200 Fully networked display and control unit in one: the Purion 200 provides compact and easy-to-read information about your speed, range and more. And, thanks to its ambient light sensor, you can quickly read the information even in bright sunshine and darkness. Located directly adjacent to your thumb on the handlebar, it lets you ergonomically and intuitively control your bike’s functions.

Warranty: Two years after pick-up when you purchase a bike. Furthermore, Riese & Muller grants you a voluntary warranty on the battery of two years: We guarantee that the battery will still have a capacity of 60% after two years or 500 full charge cycles (whichever happens first).
