Volspeed V4 has an easier and faster plug-n-play installation (no setup required)

New speed limit of 28 mph (45 km/h) on V4, where V3 has unlimited speed (more prone to errors, however, they are extremely rare)

Volspeed v4 is fitted with much more error-proof engineering.

The Volspeed tuning kit comes with original plugs and color-coded wires for an easy and perfect fit. Installation manuals and videos provide step by step detailed instructions and are easy to follow and understand. The Volspeed does not require any diagnostic tool for installation.

The tuning module is plugged into the connections of the drive unit. These are located under the left engine cover. Depending on the type of bicycle, you will need different tools to remove this cover. Most of the time you will need an ISIS crank puller and a Torx TX20 wrench.

When connecting Tuning Kit to an e-bike you will find connectors colored to make installation very simple. We have prepared detailed instructions and videos to make installation as easy as possible above. Also, our customer service is always here to help! 

Activation: After successful installation of the tuning kit, please activate it on the speedometer. Press "minus" for 3 seconds while standstill or while driving.

Volspeed is manufactured and designed in Germany and is compatible with all 2014-2021 Bosch e-bike motors (4gen / 3gen / 2gen).

The main feature of the tuning kit is removal of 16mph / 25km/h speed limiter. After the tuning kit is installed the e-bike shows actual speed on the speedometer, and also upgrades to the new 28 mph (45 km/h) speed limit.

Volspeed V4 has the new maximum speed of 28mph (45km/h) setting and cannot be adjusted.
