PearTune 3.0 for Shimano EP8 without Di2 Still On Version

This Peartune tuning kit removes the 16mph (25km/h) speed limit, allowing the motor to help you at higher speeds. For these Shimano bikes, the speed limit is raised to 31mph (50km/h).

Real speed will be displayed up to 14-15mph (21-25km/h), at higher speeds the bike will show incorrect, slower than real speeds.

The tuning kit manipulates the speed signal without altering the motor's power relative to pedaling speed. This guarantees a smooth motor control without speed limit interruptions. Depending on a tuning kit, some determine when assistance stops, while others remove the restriction entirely for continuous support. However, the achievable speed mostly depends on the eBike model. Achievable speed can be calculated using a simple formula:

Speed = Cadence [rpm] * Wheel circumference [mm] * Front Chainring Teeth / Rear Chainring Teeth * 60 [min/h] / 1.000.000 [mm/km]

The tuning kit is designed to automatically activate when the eBike is powered on. When PearTune is active - you will be able to ride at a speed of 25 mph (40 km/h) and even up to 31 mph (50 km/h)!

NOTE 1: Real speed will be displayed up to 14-15mph (21-25km/h), at higher speeds the bike will show incorrect, slower than real speeds.

This Peartune tuning kit is made to fit all Shimano EP8 and EP8-RS motors without Di2, with all Shimano displays made for EP8 motors. Not compatible with Shimano EP801!

Not Compatible with Shimano E8000 / E7000 / E5000. You would need Peatune for Shimano E8000 / E7000 / E5000. Not Compatible with Shimano EP801. You would need PearTune 3.0 for Shimano EP801/EP6

The MSO can be activated or deactivated anytime using the bike menu's light control function. Refer to the bike manual for detailed instructions. If the lights are ON, PearTune MSO is OFF. When the lights are OFF, PearTune MSO is ON. If you disconnect the red power cable, PearTune MSO will be "always ON," meaning it will activate automatically when you switch on your bike. If you have any troubles with installation or disassembly, do not hesitate to contact us.

If you are planning to install PearTune on a brand-new bike, make sure you ride it for at least 0.6 miles (1 km) before the tuning kit is activated.
