ABS on E-MTBs: Why Even Pros Are Changing Their Minds

Bosch ABS Pro

With the ABS Pro, Bosch eBike Systems is targeting the mountain biking community. What we can learn from the pros who were involved in the development and testing: Even experienced mountain bikers can benefit from the system.

Skepticism is understandable—after all, experienced mountain bikers have spent years developing a keen sense of the perfect braking response. So why trust a system that interferes with this delicate process? MTB pro Nathalie Schneitter summed up this attitude before her first ABS Pro test, speaking for many: “You don’t need any of that; I can brake on my own. I’ve been riding mountain bikes for so many years—no one can fool me.” Curiosity made her try it out anyway, and it was precisely this years of experience that made her particularly sensitive to the subtle differences—and led to surprising “aha” moments.

When Reflexes Become a Trap

Even the best riders reach their physical limits. During an unexpected emergency stop on loose terrain, the reflex kicks in: maximum braking pressure, immediately. This is exactly where the Bosch eBike ABS Pro comes in—not to patronize, but as an intelligent filter for those critical first milliseconds. The system works differently than expected: Instead of intervening continuously, it reduces the initial braking force when riders reflexively apply the brakes too hard. The system quickly assesses: Okay, we need to release more braking force again, explains Schneitter regarding the intelligent control system after her practical test.

Two ABS modes for different needs

In Trail Pro mode, the eBike ABS operates with rollover protection—ideal for unfamiliar routes and changing terrain. Race mode disables the rear wheel lift control and enables maneuvers like switching lines in hairpin turns.

Sport brake instead of safety system

Schneitter’s conclusion after 25 ABS interventions on her home trail is surprising: “I would describe the ABS Pro less as ABS and more as a sport brake.” The system doesn’t interfere with braking, but increases safety by a few percentage points and brings more flow to her rides.

The technology behind the eBike ABS Pro: a 56-slot sensor disc on the front wheel enables more precise detection, while a new sensor in the motor analyzes the riding situation—incline, terrain, speed.

More flow through later braking points

The result: riders can brake significantly later, ride unknown trails with greater confidence, and maintain control. This safety margin is particularly relevant for e-MTBs with higher system weight and increased performance.
