VOLspeed PW V2 is a speed unlock (speed derestriction) tuning module designed specifically for Yamaha PW (V2) drive systems on e-bikes across all model years.
The module installs permanently on the mid-drive motor and stays invisible from the outside once fitted. It works as an interposer electronics module between the drive system components.
All configuration is done on the bike display (display settings) using the arrow buttons on the control unit, so no smartphone or PC is required. Installation takes about 15 minutes and needs some technical skill, while keeping all cables uncut thanks to plug-and-play connectors.
Key benefits of the VOLspeed PW V2 tuning module
- Adjustable speed limit range – tuning mode lets you set the assist cut-off from 25 to 99 km/h using the arrow buttons.
- Control via the handlebar unit – the tuning (tuning control) is operated using the control unit arrow keys you already have.
- Remembers your last setting – the module stores the last configured speed limit value for quick re-selection.
- Tuning starts OFF after power-up – each time you turn the e-bike on, VOLspeed starts with tuning disabled.
- Dynamic mode for smoother cut-off – the dynamic “throttling behaviour” option makes assist disengagement at the limit noticeably less abrupt.
- Correct ride data on the display – the system shows accurate speed, trip distance, average speed, and maximum speed with tuning active.
- More realistic range prediction while tuned – the range estimate accounts for riding style and consumption, not only battery level and assist mode.
- Total mileage stays correct even after removal – the bike’s total mileage remains accurate even if the VOLspeed module is removed later.
Who is this for?
This VOLspeed PW V2 speed unlock module is for standard 25 km/h pedelec e-bikes equipped with the Yamaha PW (V2) drive system. It is built for Yamaha PW line motors in the PW (V2) version and is intended for all model years using that system.
The module mounts at the central mid-drive motor area and is aimed at riders who want to adjust the motor assist cut-off speed and the cut-off behaviour through the display (on-display configuration). The ability to raise the limit to a moderate value, such as 32 km/h, supports a sporty ride with measured consumption and more efficient battery use.
This specific VOLspeed variant does not fit Yamaha drive systems that are not Yamaha PW (V2). It is also not suitable for children’s or youth bikes limited to 20 km/h from the factory, and it is not suitable for S-pedelecs rated for 45 km/h.

Why choose VOLspeed PW V2?
VOLspeed PW V2 is built around on-display control (display setting) rather than external apps, so the speed limit and behaviour can be changed directly with the arrow keys on the control unit. This approach keeps setup simple and keeps the bike free from phone pairing or computer connections.
The module is designed for a permanent, hidden installation on the Yamaha PW (V2) motor, and it connects using plug-and-play connectors without modifying cables. That installation concept keeps the upgrade visually discreet while avoiding wiring damage during fitting.
Unlike solutions that virtually eliminate any practical cut-off, VOLspeed supports sporty riding with controlled consumption. For example, setting the assist limit to 32 km/h can maintain more efficient battery usage, while the dynamic mode reduces the harsh “wall” feeling at the cut-off point.
