Key Features of Kalkhoff Agattu b8

– Bosch Performance Line motor

– Intuvia display with USB port

– 75 miles of range with large 500 Wh battery

– Magura HS11 hydraulic rim brake

Motor: While many ebikes utilize a hub-mounted motor located in the rear wheel, Kalkhoff ebikes feature the revolutionary mid-mount Bosch eDrive System, which positions the motor at the lowest point along the center of the frame. This gives Kalkhoff Electric ebikes more even weight distribution, which ensures better handling and more stability.

The Bosch eDrive System is maintenance-free and produces very little noise and vibration compared to many other electric-assist motors. Plus, with the battery mounted along the downtube, it’s easily accessible for recharging, and is also simple to detach.

Battery: Bosch PowerPack 500 Performance, 36 V, 13,4 Ah/500Wh – The most powerful PowerPack available from Bosch. Ultra-modern Bosch lithium ion batteries with 500 Wh energy reserve provide the power for our E-Bikes. The more Watt hours the battery has, the wider its range. This also depends on numerous other factors, such as the pedal assistance level set, the pace, the outside temperature or the inclination of the route. The range computer on the display provides more detailed information. When it’s stop-and-go in the city, the range is shorter than with a constant journey over a longer distance – comparable with the fuel consumption of a car. If you find while you’re on a ride that your battery’s residual power is not going to be enough to complete your journey, you can reduce the degree of assistance and therefore still reach your destination comfortably.

The lifespan is 800 – 1,000 charging cycles. Thanks to the short charging times, the battery can be significantly topped up during a lunch break, for example. A complete charge takes just 4.5 hours.

Display: The variable mode Bosch Intuvia LCD display has two main functions; to allow the rider to control drive parameters, and to display system information, including distance, time and speed. The control pad allows you to access all the computer and drive functions remotely, leaving your hands on the bar to maintain safety and security. To change motor settings while riding, simply push the large, glove friendly keys on the handlebar control pad. This ensures safety and stability, while still allowing you to control the motor for optimal performance.
