VOLSPEED V4 - available now!

What's new? 

Easier installation, less errors - new 45km/h / 28mph speed limit.

 The previous VOLspeed Bosch V3 (P/N 1144) will be available at least until the end of the year to ensure a smooth transition. 

In addition to the new features, the new module offers almost all the characteristics of its predecessor, but generally, no more bikes have supported that support up to 20km/h (12.4mph) or up to 45km/h (28mph) from the factory. In addition, only a maximum limit of 45km/h (28mph) can be set. This restriction will also apply to all other VOLspeed modules in the future. Therefore, new modules for Giant and Yamaha will also be released soon.


The dealer prices have not yet been fixed, but could increase slightly due to higher purchase prices this year. We will revise our calculation for all modules in the coming weeks and inform you accordingly. 


VOLspeed V4 Tuning Kit Compatible with all Bosch motors 2014-2021, even with the 4Gen motors!
Warning - does not work with 2022 Bosch Smart System

Product Features

Compatible with the following Bosch motors: Active Line, Active Line Plus, Performance Line, Performance Line, CX Line including motors of the 4Gen (2014 onwards). Works with the latest Bosch update released on 2020 09!

The tuning kit can be activated directly on your eBike’s display or controlBefore the first use of the Tuning Kit, the Setup must always be carried out first. Setup by pressing ‘- and +’ on the control. You will find detailed instructions with your tuning kit. 

The activation is by pressing ‘- and +’. You would need to press ‘-’ and hold in 3-5 seconds, then release the ‘-’ and press ‘+’ and hold in 3-5 seconds. And you will see a 6.8 mph (11.1 km/h) speed display - it will show that the tuning kit is activated. 

From now on you can easily choose and set a new max speed.  Have the option of setting the level of maximum engine support to an individual value between 16mph and 61mph (25 and 99 km/h). If you raise the level of engine support only slightly, e.g. from 16mph to 21mph (25 km/h to 35 km/h), you can still drive very sporty, but at the same time benefit from moderate battery consumption.

After the dongle is installed, your e-bike display will show real data, such as maximum and average speeds, daily mileage and cruising range. 

Adjustable dynamic mode with reduced "wall effect" – that means the motor support does not stop so abruptly anymore when the maximum speed is reached. The result is a more pleasant driving experience, as you can drive with much more constant pedal force.

Please be aware that the Tuning kit does not add extra power to your eBike motor. It only removes speed limits and enables you to ride as fast as you can pedal.

The box is splash-proof.

Bosch diagnostic is not able to find if you were using VOLspeed or not. Also, please be aware that all the tuning kits are carefully tested before sending them out to You.
