ZF shows CentriX motor for e-bikes at Eurobike 2025
The enhanced version of its CentriX e-bike drive system underlines the German supplier’s growing ambitions in micromobility. The compact mid-drive motor now delivers up to 105 Newton metres of torque and 750 watts of peak power—while retaining its 2.5-kilogram form factor, roughly the size of a drinks can.
The new performance levels are unlocked via software and are accessible through preset ride profiles available in the newly updated “ZF Ride” app. According to ZF, these modes—Race, Wet and Ride—are designed to adapt motor behaviour to different use cases with just a tap. Existing CentriX units already in the market can also benefit from the upgrade via a firmware update.
The ‘Race’ profile is aimed at riders seeking peak performance in dry conditions. In this mode, the drive system delivers full 105 Nm torque and 750 W power with immediate response. The cut-off at 25 kph is sharp, offering a no-compromise experience for dynamic riding.
By contrast, the ‘Wet’ profile reduces power delivery and overrun to ensure better control on slippery terrain. It is tailored to prevent rear wheel spin or loss of traction when cornering on damp surfaces.
The ‘Ride’ setting, optimised for daily commutes and mixed use, balances support modulation and rider input across varying terrains. The motor automatically adjusts its assistance ratio based on input power, delivering full support when rider effort exceeds 350 W. In ‘Boost’ mode, the drive provides maximum assistance, with overrun modulated according to speed.
All profiles affect critical motor parameters: overrun (within the 2-metre legal limit), startup sensitivity, power scaling at top speed, and peak output. ZF confirms the system recalls the last-used profile at start-up.
“With the new riding profiles, users can adjust their ZF drive even better and faster to their respective application,” said Daniel Haerter, Head of the Micro Mobility business unit at ZF. “Using the software, we tease the optimum out of our now even more powerful drive for typical driving situations.”
Series production of the CentriX drive system began in spring 2025. By introducing app-based ride profiling, ZF is positioning its CentriX system as a fully adaptive e-bike platform—an increasingly vital feature in a maturing segment where rider personalisation and performance tuning are key differentiators.
