Bosch presents new Performance Line SX e-bike motor

Bosch, a leading manufacturer in the e-bike industry, recently introduced the new Performance Line SX motor. This motor is designed specifically for the growing lightweight e-bike segment and is said to have a system weight of less than four kilograms.

Lightweight e-bikes on the rise

Lightweight e-bikes are becoming increasingly popular. They offer the ride feel of a conventional bicycle, but provide additional boost when needed, such as on inclines or intense rides. Bosch, as an established supplier of e-bike drives, is responding to this trend with the introduction of the Performance Line SX motor.

Technical details and features

The Performance Line SX motor is designed as a drive for sporty riders. It is designed to provide reliable support even at high cadence and reach a maximum peak power of 600 watts for short periods. The motor itself consists of a magnesium housing and weighs only two kilograms. The maximum torque is 55 Nm.

The motor has a new driving stage called Tour+, which is supposed to enable dynamic power distribution. The harder the rider pedals, the more power the e-drive delivers. There is also a new sprint mode that supports maximum acceleration and helps maintain a high speed. All modes can be personalized via a corresponding app.

New battery and additional battery

Along with the new motor, Bosch has introduced a new battery, the CompactTube 400. This battery is said to impress with its compact shape and high energy density. With a capacity of 400 Wh, it is the smallest and lightest battery for integration in the down tube that Bosch offers.

In addition, Bosch offers an additional battery as a range extender, which fits in a bottle cage and has a capacity of 250 Wh.

Application areas and availability

Bosch sees the new drive primarily in lightweight E-MTBs, gravel bikes and urban bikes. Pedaling resistance is said to be reduced by 50 percent compared to other Bosch motors, which should make it easier to ride above the 25 km/h support limit. In addition, the new drive is said to be significantly quieter and feature a low crank distance (Q-factor) of 160 millimeters. The first models with the new drive are scheduled to come onto the market in fall 2023.
