Only Bosch e-bikes with the old "Classic Line" drive system (model year 2013 or older) or with the new "Smart System" (model year 2022) are no longer supported. The "Smart System" is also referred to as "BES3" or generally "Gen5".

Just as an update, I got my V4 from yourselves the other day via the Bay. All fitted up fine, was really worried that the available space was going to be a problem though, and at first was thinking 'hmm this motors gonna have to come out' with a view to poking the module up into the seat tube or summat (this is on a 2020 Haibike AllMtn3 btw). Individual activation code. It is possible to set an individual code with which the tuning can be activated using the control buttons on the e-bike (function is not available with Smartphone Hub and Cobi). Dynamic mode: In this mode, the motor support no longer stops so abruptly when the set maximum speed is reached. The result is a more pleasant driving experience.The VOLspeed V4 module must be connected to the e-bike motor, invisible from the outside. To do this, the module must be plugged into the connections on the motor. As these connections are located under the left motor cover, the motor cover must be temporarily removed for this. Special tools are needed to remove the cover, usually an ISIS crank puller and a TX20 Torx spanner (depending on the model). Note: To be able to use the module to its full extent, the display of the total kilometres and speed is essential. If you ride an e-bike without a display, you can use the Ridecontrol app. Changes in the product range You can easily tell if you have a Bosch Smart System eBike if it is fitted with an LED remote control. Many are fitted with a Kiox 300 or Intuvia 100 display. If your eBike has either a Purion, Intuvia or original Kiox. You have a non-smart model. You will be able to fit either the VOLspeed V4 or Speedbox 3.0 that we discussed earlier in this post. Best Bosch Smart System Tuning Chips The V3 was the most reliable tuning chip on the market, resulting in very few 504 (anti-tuning) errors. The majority of errors are caused by riders consistently exceeding a high speed limit (>45km/h). As a result the V4 will only allow you to set a new max speed from 25-45km/h. VOLspeed have also improved the anti-tuning technology to reduce the chance of errors further, even on the most recent software update. Advanced Programming

If you are already using the individual assistance modes in the Nyon or Nyon 2, these always have priority over the settings of the tuning module. If you have activated these modes in the Nyon, the settings made there are used, otherwise the values in the tuning module are used. Correct speed display After switching on, the speed limit can be freely set in the range 25 – 45km/h (28mph) using the arrow keys. The last set value is stored. Setting of a smoother “throttling behaviour” possible (dynamic mode). The otherwise very abrupt cut-off at the speed limit is therebysignificantly softened. Wheel circumference adjustable (+/-10%) to improve the accuracy of the speed display and distance measurement.Tuning modules for Yamaha and Bosch e-bikes are offered under the name VOLspeed. The special feature of these tuning tools is that the tuning settings can be easily customised via the control buttons of the e-bike display - without a PC or smartphone. For example, you have the option of increasing the level of maximum motor assistance to a value of your choice; the 25 km/h speed limit is thereby lifted. With the VOLspeed V3 for Bosch, there is also the option to specifically optimise to 32 km/h (Bosch Gen4 error limit). Another original feature is the option to set a so-called "dynamic mode" - in this mode the unpleasant "wall effect" is mitigated, by which is meant the abrupt interruption of motor support when reaching the maximum supported speed. This leads to a considerably improved driving experience. In addition, the tuning can be switched on or off at any time via the e-bike display. Another plus point: even when tuning is active, the correct speed is shown on the display. As you can see, the VOLspeed Tuning Chips are extremely versatile tuning modules with which you can optimise the riding characteristics of your Bosch or Yamaha e-bike in many ways. If you're looking for the most advanced features and smartphone compatibility. We highly recommend the SpeedBox 1.0 B.Tuning. This premium version allows riders to connect their eBike to the SpeedBox app (available on iPhone & Android) where they can control their tuning chip and see accurate ride data in real time. It's also worth considering the sIMPLEk. It's so small & easy to fit, making it an excellent choice for riders that don't have much space inside the motor. The VOLspeed V4 tuning chip is an updated version of the hugely successful V3 model. It is compatible with a variety Bosch eBikes from 2014-22. Please note it is not compatible with the 'Smart System' models releasing at the end of the year. Due to the plug-in connections, disassembly is basically just as easy as installation. There should be no visible damage to the e-bike or pedelec.
