NOTE: Conventional tuning modules offer only limited functionality compared to today’s e-bike standards. They often rely on complicated display button sequences for activation, deactivation, and speed-limit adjustments — making them cumbersome to use. Moreover, these tunings are highly vulnerable to firmware updates, which can easily disable them.
In contrast, the EPAspeed B.Tuning series represents the next generation of e-bike tuning — fully app-controlled, firmware-resistant, and designed for effortless operation. With Bluetooth connectivity, intuitive controls, and invisible tuning functionality, EPAspeed delivers precision, reliability, and freedom unmatched by conventional solutions.

VOLSPEED FOR YAMAHA
Tuning module for e-bikes / pedelecs with Yamaha PW-X / PW-X2 / PW-SE / PW-ST / PW-TE / PW-CE drive system of all model years. It works with all displays.
Compatible with motors:
PW-SE
PW-X
PW-TE
PW-CE
PWX2
PW-ST
NOT COMPATIBLE WITH:
Yamaha UrbanRush
CrossCore
CrossConnect
Wabash
PW-X3
YDX-Torc
YDX-Moro
YDX-Moro Pro
The device is installed invisibly on the drive motor from the outside. No cables have to be damaged or modified, the module is simply plugged in. The tuning is only 37x19x9 mm and completely waterproof.
No PC or smartphone is required. All settings are made conveniently via the display on the bike.
The ability to set the speed limit, the speed limit behaviour and the wheel circumference via the display is unique.
In contrast to the almost complete elimination of the motor's limitation in other tuning modules, with this module you can still achieve a very sporty driving style with moderate battery consumption by slightly increasing the limit, for example to 32km / h. In order to reduce the very abrupt interruption of the motor support at the speed limit, the speed limit range can be expanded to double the speed range.
The module also supports S-Pedelecs and pedelecs throttled to 20km / h.
FUNCTIONS
Tuning can be switched on and off via handlebar buttons.
The speed can be freely adjusted after switching on using the arrow keys in the range 25 - 45km / h. The last set value is saved.
The tuning is always switched off after switching on the bike.
Setting the "softer control behaviour" possible (dynamic mode). The otherwise very abrupt lowering of the speed limit is thereby significantly mitigated. The last setting is saved.
DYNAMIC MODE
Adjustment of the wheel circumference possible during setup.
Correct display of speed, distance covered and average and maximum speed at all times.
With active tuning, the remaining range calculation takes into account not only the charge level of the battery and the selected support level, but also the current driving style / battery consumption.
Correct total mileage of the bike even after removing the tuning module, as the kilometers are tracked in the engine control by the tuning module.
Supports pedelecs (25km / h), S-Pedelecs (45km / h), as well as bikes throttled to 20km / h.
