New Bosch 2021 Electric Bike Features Revealed

First Look: Bosch eBike Features for 2021 Revealed

By Ben Mowbray |

We take a look at the new Bosch eBike features revealed for 2021 electric bikes. Each year, Bosch make updates to their hardware and software and you can learn all about the new Bosch Performance Line CX 2021 and other components, right here.

New Bosch Performance Line CX 2021 Motor Updates

The Bosch Performance Line CX 2021 motor is one of the most advanced on the market. Utilising multiple sensors which communicate over 1000 times per second, these sensors relay information require to bring you the most precise/powerful eBike assistance offering maximum agility and control.

For 2021 it gets a whole lot better, in a host of different ways. Read on to find out more...

NEW - Increased Bosch Motor Drive Torque

Bosch CX 2021 - Bosch has increased the motor torque to 85Nm, up from the previous 75Nm, achieving a 12.5% increase on torque across the board. This torque increase has a noticeable effect on riding behaviour.

New 2021 Bosch CX Motor Supports Up To 85Nm

The new CX motor allows for faster acceleration, particularly on standing hill starts but also at lower cadences. The new Performance Bosch CX 2021 update keeps the high 340% assistance available to the rider.

NEW - Bosch CX "Extended Boost"

Extended Boost for 2021 is a brand new function for working your way through the really rough stuff. Exposed roots, steps and stairs, boulders and everything in between can be traversed with ease, even when heading uphill.

Bosch 2021 eBike Performance CX Motor

This totally new and unrivalled function allows for a much-improved level of manoeuvrability. The unique dynamic of the new Extended Boost function allows the rider to overcome obstacles with ease simply by applying the correct amount of pressure to the pedal.

Bosch's innovative function in eMTB mode can be controlled to great effect across all terrain types; with the front wheel is already on a step, slight pedal pressure is all it takes to provide that needed "kick" up - A whole new level of pedal management!

New CX Hardware Features:

Up to 340% assistance in Turbo Mode.
Cadence support up to 120 RPM.
Torque increased to 85Nm.
Weight: Circa 2.9 Kg.

NEW - Bosch CX "Perfect Control"

The freshly tweaked eMTB mode now gives you even better control on the trail without any need to flick between riding modes. A new firmware upgrade allows the motor to respond far more sensitively to rider input, especially in low gears, making even those seemingly near-vertical hill starts a much smoother affair!

Bosch's all-new Advanced eMTB mode makes sure that eBikers of all abilities are best equipped for whatever riding situation the trail may throw up on the day.

Bosch eMTB Mode Advanced for eBike in 2021

New hardware control

Brand new sensor/motor control functions give eBikers a much wider range of both dynamic and natural support. Using torque sensors to measure pedal pressure, Bosch's progressive motor support adapts to any riding situation.

The newly improved adjustment of eMTB mode in the latest update ensures optimum control of traction. Start-up torque is also overhauled - it's now much finer and more sensitive, especially so in lower gears.

All of this will help beginners - the Bosch electric bike is now 'easier' to ride. There's a broader cadence range and if the rider misses or selects the wrong gear whilst accelerating out of bends, the system will respond with more or less power to help the rider by managing the assistance in the most advanced and natural way to date.

Already bought a 2020 bike? No problem! All of these features will be backwards compatible with the 2020 Bosch Gen 4 CX Motor and will be available from us exclusively for our eBike customers as part of our routine maintenance/servicing offering.

New 2021 Bosch Nyon eBike Control

A whole new screen


New 2021 Bosch Nyon Navigation Controls

The new 2021 Bosch Nyon eBike Controller paves the way for a new generation of eBiking. The new eBike Connect App seamlessly integrates smartphones and the new Bosch Nyon controller to share data about activities and routes taken.
