On the following pages, you will find tips and tricks on how to determine their range, optimize their efficiency, and maximize their service life. The PowerPacks are efficient and reliable energy suppliers for when you are on the go. At approx. 2 to 2.6 kg, they are real lightweights, with energy density (Wh/kg) that takes a leading position among ebike batteries.

When installed as a frame battery, the PowerPack is very close to the center of gravity of the bicycle and thus has a very positive effect on the handling. The rack variant is frequently used on step-through bicycles to offer as much clearance as possible when getting on and off the bike. Frame battery PowerPacks are the fuel tanks of the ebike. State-of-the-art lithium-ion technology makes them into efficient and longlasting suppliers of power. As an ebiker you can ride with them very economically and thus maximize the range of a rechargeable battery charge. Tips and tricks for optimal range: Cadence Cadences above 50 revolutions per minute optimize the efficiency of the drive unit. In contrast, very slow pedaling is very costly in terms of energy. Rack battery Weight The mass should be minimized by keeping the total weight of the bicycle and luggage from being unnecessarily high. Starting & braking As with a car, frequent starting and stopping is less economical than long distances at a nearly constant speed. Gear shifting Correct shifting also makes ebiking more efficient. It is best to start off and take inclines in a low gear. You then switch to a higher gear in accordance with the terrain and speed. Tire pressure Rolling resistance can be minimized by proper tire pressure. Tip: Always ride with the maximum allowable tire pressure. Motor performance indicator Pay attention to the motor performance indicator of the on-board computer and adjust your riding style accordingly. A long bar means greater power consumption. Rechargeable battery & temperature With decreasing temperature, the efficiency of a rechargeable battery goes down, since the electrical resistance increases. In winter you can thus expect a reduction in the normal range. 6 Range 7 Far-reaching technology Active Line range Support modes, riding behavior, and external factors influence the range. For the PowerPacks, the following graphics provide an overview of the range as a function of a variety of conditions: Cruise with PowerPack 300 Turbo Sport Tour Ideal conditions* Flat terrain, approx. 15 km/h, no headwind, low rolling resistance, proper shifting, weight without ebike 85 kg The above conditions are assumptions that can be both exceeded and undershot. ** The range of
