Motor manufacturer Bosch has delighted all e-bike owners with Bosch SMART Gen5 systems today. A major software update has been released, promising a significant improvement in torque and overall motor performance. But what does this mean for your favorite speed limit removal? We have good news for you.
If you follow the latest news in the e-bike world, you certainly haven't missed today's hot topic. In May 2026, Bosch officially released its new Performance Upgrade 2.0, which pushes motor performance even further—specifically by increasing the torque value up to 120 Nm. This is a direct response to the recently introduced AVINOX M2S motors, which shifted the parameters of this entire segment to a new level.
Software Updates vs. Tuning: No More Worries
In the field of e-bike tuning, we know that these updates sometimes bring the necessity to update the tuning chip's firmware as well. Occasionally, after uploading new software to the motor, older tuning chips may stop working, display error codes, or the system might switch directly to emergency mode. Many cyclists therefore prefer to wait with the update until the chip manufacturer confirms compatibility.
But you don't have to wait! If you want to fully utilize the new performance potential of your Bosch Gen4 and Gen5 motors while enjoying a ride without the limiting 25 km/h restrictor, our PearTune MSO chips are fully compatible even with this major software update.
