Since 2018, the VOLspeed company from Ehekirchen in Bavaria has been one of the leading manufacturers of innovative tuning modules for e-bikes, pedelecs and S-pedelecs. The VOLspeed Performance V4 tuning module for e-bikes and pedelecs with BOSCH drive systems is a product on the market whose individual optimisation options are unique.
The tuning module for e-bikes with BOSCH motors
The VOLspeed tuning module is suitable for the following BOSCH motors: All BOSCH drives since model year 2014, i.e. Active Line, Active Line Plus and Performance Line (CX). Attention: No support for the "Smart System", also known as "BES3", from model year 2022.
Plug & Ride
In contrast to the previous models, a setup is no longer necessary. The tuning module can be used immediately after installation. All necessary settings are made automatically. This also applies in the event of a conversion, temporary removal or when replacing the display.
Individual assistance modes
For each riding mode (TURBO, EMTB/SPORT, TOUR, ECO) the power of the motor itself can be adjusted. The assistance can be adjusted according to the speed, but the original settings remain, so that you can very easily choose between your own and preset modes while riding. This is done with the WALK button. There are now four different settings for assistance per driving level. The tried and tested "dynamic mode", which controls the motor noticeably softer, is still available and can now be combined with the standard mode or a custom setting. The speed display only briefly jumps to a different value so that you can see which mode is active.

12 km/h Alternative mode
13 km/h Alternative and dynamic mode
By default, the alternative mode, which can be set by the rider, is already preset. The three modes ECO, TOUR and SPORT are set so that the assistance is slightly higher than the original setting. When switching to the alternative mode, the support is then slightly stronger. Of course, each level can also be configured individually. With the module activated, simply select the driving level while stationary, then briefly press the push-assist button and then the minus button. Now the plus button can be used to switch to the setting for 10 km/h, 20 km/h and above. Pressing it again ends the process and all values are saved.

eMTB mode and TOUR+ mode
The strength of the pedal force support is different in these modes: in eMTB, the support is not permanently at 210 %, but can be above or below this depending on the pedal torque. However, these modes can also be specifical
Money-Saving Tip: To remove the cranks from e-bikes quickly and easily, you’ll need a Puller. This tool is already included in our Tuning Chip Set E-Bike.
ATTENTION: To avoid installation errors, please be sure to read the product descriptions and Instruction Manuals for the respective Tuning Chips. Additional information is available in this blog post: E-Bike Tuning and Software Updates.
