Bosch eBike Systems
The well-known line of motors from Germany’s Bosch comprise the most popular mid-drive e-bike system.
Because of its well-established reputation for excellent electric motors, Bosch quickly established itself as an industry leader and is found on many e-bike brands in the marketplace. There are four motor models in the
Bosch line-up and all are 250W, but each is designed and tuned for different e-bike users. The Active Line, a modern, elegant design, is for urban e-bikes; the Active Line Plus provides a versatile, optimal drive for exploring country roads; the Performance Line is for trekking, all-mountain riding or commuting; and the
Performance Line Plus offers a maximum torque of 75Nm, which is ideal for e-MTB enthusiasts. Bosch’s internal gear system uses nylon gears that mesh together and power a single chainring that operates at a relatively high rpm. As Bosch manufactures each part of its e-system, problems are easy to diagnose while the design allows all batteries and displays to work with each of its motors. Its basic control units, Purion and Intuvia, are most prevalent. A new entry, Nyon, forms part of an intelligent system that combines with a smartphone app and web portal to enable a networked e-bike experience. Bosch’s most popular batteries are its 400 and 500 Powerpacks. Additionally, it offers the 500 PowerTube and the Dual 500 of either model, for 1,000Wh of capacity.
