Frequently Asked Questions

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 (22-25km/h), at higher speeds the bike will show incorrect, slower than real speeds.

The tuning kit can be activated directly on your bike’s display. After pressing the 'LIGHT' button, from now on you will be able to ride at a speed of 25 mph (40 km/h) and even up to 31 mph (50 km/h)!

To deactivate the tuning kit, press the 'LIGHT' button again. Your e-bike will then work the same as before installation of the chip.

If the Light button is not activated on your ebike, do not connect red cable, and tuning kit will be activated when you will turn on the ebike.

This Peartune tuning kit is made to fit all Shimano EP8 motors, with all Shimano displays made for EP8 motors.

Works with Giant Revolt E+ with Di2 powered by Shimano EP8

Not Compatible with Shimano E8000 / E7000 / E5000. You would need Peatune for Shimano E8000 / E7000 / E5000.

When connecting Tuning Kit to an e-bike you will find connectors colored to make installation very simple. We have prepared detailed instructions and videos to make installation easy for you. Disassembly of our tuning kit is just as easy. 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.
