I'm looking for a new bike and saw there are big differences with the new motor
I was interested in getting one but see they cannot be derestricted...

10 FACTS ABOUT THE 2020 BOSCH PERFORMANCE LINE CX
- More powerful: while torque remains constant at 75 Nm, the support of the new CX motor has been increased from 300% up to 340%.
- More compact: compared to the previous model, the volume has been reduced by almost 50%. Granted, the previous CX motor was quite bulky! This will allow for better, more sophisticated integration as well as improved bike geometry.
- Lighter: the new CX motor features a magnesium housing and weighs 25% less than its predecessor – around 2.9 kg.
- More sensitive: eMTB mode has been reprogrammed to deliver consistent power over a wide cadence range. Sprinting out of the gate or pedalling at an even cadence? In eMTB mode, the support feels very natural!
- Better modulation: Turbo mode has also been updated and is less choppy, especially when you get going, though still very powerful! As usual, the CX motor has four modes: Eco, Tour, eMTB and Turbo.
- Smoother: the transition at the 25 km/h threshold has been significantly improved. Instead of a mini chainring and a gearbox, the power is now transmitted directly via a large chainring. The motor has almost no internal resistance, which should eliminate the draggy feel of the previous model when pedalling above the 25km/h cut-off.
- Quieter? unfortunately not. The new motor has some noise issues – especially with the chainring’s new freewheel (for more details see our review on page XX).
- Narrower: the Q-factor (distance between the cranks) has been narrowed down to 175 mm in order to provide a more natural pedalling sensation. The narrower, the better. To compare, Yamaha’s motor is under 170 mm, Shimano’s is at 177 mm, and Brose’s is more or less 180 mm wide (depending on the cranks).
- Greater capacity: in addition to the previous 500 Wh internal battery, you’ve now also got the PowerTube 625, for more capacity and longer rides.
- Goodbye tuning: new anti-tuning software detects motor tuning and manipulation via sensors while you’re riding which then automatically switches the motor into limp home mode. Bosch is thus responding to the requirements of the EN15194: 2017 standard.
