SACHS is primarily known as an automotive supplier, with the brand's beginnings dating back to 1895. Acquired by Mannesmann in 1997, SACHS merged with ZF Friedrichshafen AG in 2011. Today, SACHS is a brand of ZF Friedrichshafen AG. The broad product range includes, among other things, high-quality drive components, but also chassis components such as damping systems and shock absorbers - not only for cars and trucks, but also for motorbikes, rail vehicles, etc. The headquarters for development, sales and production of the SACHS brand are located in Schweinfurt / Germany.
In 2018, the starting signal was given for SACHS Micro Mobility, a joint venture of ZF, Magura, BMZ and BFO. Already in the same year, the company presented the SACHS RS Motor, its first e-bike drive system. At the Eurobike 2019, further Sachs motors for different e-bike types were presented.
Sachs e-bike motors
The classic SACHS RS e-bike motor set completely new standards in terms of performance with an outstanding maximum of 110 Newton metres. The drive was primarily developed for urban, cargo and, of course, e-MTBs. It is particularly interesting that the RS drive delivers a very high torque even at low pedalling frequencies such as 40-60 pedal revolutions per minute. This is especially beneficial for inexperienced off-road riders or cargo bike riders in tedious stop-and-go traffic in the city. This power pack is also said to cope well with steep climbs. Thanks to innovative engine management, the drive scores not only with a beautifully controlled power delivery and harmonious support, but also with high ranges - even in the strongest riding mode (as a rider, you have the choice between four different riding modes). The weight of the RS motor is 3.5 kg.
SACHS Micro Mobility gives e-bike manufacturers the option of integrating the RS motor individually into the respective vehicle concept. The drive system is available in a pedelec (25 km/h) and an S-pedelec version (45 km/h).
Depending on the e-bike type and application, manufacturers can also choose between various Sachs Micro Mobility batteries. The range extends from standardised platform systems to customised individual solutions.
Incidentally, SACHS Micro Mobility presented several new e-bike motors for different applications at the Eurobike 2019. For example, the Sachs GT 525, which weighs just 2.8 kg and should be a perfect fit for e-hardtails and e-citybikes. The RS 925 was specially developed for e-mountain bikes, and with the Sachs CT 725, the company even presented a motor that was specially designed for heavy loads - an ideal solution for e-cargo bikes.
Can Sachs e-bike motors be optimised?
Yes! Although SACHS Micro Mobility has only been on the market since 2018, there are already the first tuning tools with which you can cancel the preset speed limit of SACHS e-bike drives.
