Safety is a key issue for many eBike riders. The world's first production-ready eBike ABS enables controlled and stable braking, even under difficult conditions. Bosch has been an expert in ABS systems and a market leader in motorbike safety systems for over 40 years. The eBike ABS was developed using the already established motorcycle ABS from Bosch as a starting point. eBiking becomes safer through the combination of front wheel ABS and rear wheel lift control. The pressure at the front brake is regulated during harsh braking manoeuvres and stabilises the bike. This provides advantages particularly while trekking and riding in the city and allows you to enjoy leisure rides or the daily commute to work in total relaxation.
User-oriented eBike ABS
The Bosch eBike ABS is specifically designed for city, touring and trekking eBikes with 28-inch wheels.
Controlled braking force
Over the past few decades, braking systems have been continually developed. Thanks to cable pull, hydraulic and disc brakes, braking systems have become very powerful. The eBike ABS gives the rider more safety and controls the braking force.
A study by the Bosch accident research team confirms the potential of the anti-lock braking system: If all pedelecs were equipped with ABS, up to 29% of pedelec accidents could be avoided each year.
The safety of eBikers is enhanced through the combination of front wheel ABS and rear wheel lift control. The brake pressure on the front brake is regulated during critical braking manoeuvres and thus stabilises the bike.
The interplay of the Bosch eBike ABS components ensures greater safety. The eBike ABS consists of:
1. the ABS control unit
2. the ABS light (or integrated into Kiox/Nyon since model year 2021)
3. two ABS wheel speed sensors, one on the front wheel and one on the rear wheel
4a. the Magura CMe ABS brake
4b. with ABS sensor disc and brake disc
The complete set weighs around 800 grams. The anti-lock braking system is automatically enabled above a speed of six kilometres per hour.
Wheel speed sensors monitor the speed of both wheels. If locking of the front wheel is anticipated under harsh braking, eBike ABS from Bosch will control the braking pressure and improve the riding stability and steerability of the eBike – especially on slippery road conditions. Well-judged and sensitive braking behaviour significantly increases control and stability.
Rear wheel lift control
The intelligent rear wheel lift control of Bosch eBike ABS reduces the possibility of the rear wheel lifting when the front wheel brake is applied forcefully. The likelihood of being ejected over the handlebar is reduced. The front brake can be used more actively and efficiently.
The eBike ABS has been compatible with all Bosch eBike components since model year 2021, except for eShift, SmartphoneHub and COBI.Bike products.
"The introduction of such a system can sustainably increase traffic safety"

ABS for Performance Line Cruise and Speed
The first ABS eBikes were already on German roads with selected fleet partners in spring 2018. Bosch eBike ABS was initially used for the Performance Line Cruise and Speed in combination with Intuvia on trekking and city bikes with 28 inch tyres.
Since autumn 2018 pedelecs from different producers equipped with Bosch eBike ABS have been available for purchase.
