ALUTECH P120 Complete Drive System – Aftermarket Conversion Kit for Shimano EP6 / EP8 / EP801 Equipped Bikes

ALUTECH P120 Retrofit Kit for E-MTBs with Shimano EP6, EP8, or EP801

Give your bike a power boost

Do you want to upgrade your E-MTB—currently equipped with a Shimano EP6, EP8, or EP801 drive—to the new ALUTECH P120 drive system?
Then this complete retrofit kit is the perfect solution.

The ALUTECH P120 motor, manufactured by Gobao, features the standard Shimano 6-bolt motor mount.
This allows the system to be integrated into a wide range of E-MTB frames designed for the Shimano EP6, EP8, or EP801.

This gives your trusted bike state-of-the-art drive technology with up to 120 Nm of torque, 800 W peak power,
and individually configurable riding modes—all without needing to replace the frame.

The retrofit kit offers you the chance to bring your existing bike up to the latest technical standards
and benefit from the performance of the ALUTECH P120 drive system.


The appropriate ALUTECH software comes pre-installed from the factory – available for either 27.5" or 29" wheels.
The system is therefore ready for immediate use: Ready to Ride.

Powerful and customizable

The ALUTECH P120 system offers six assistance modes:
-Auto – up to 110 Nm
-Eco – torque individually adjustable
-Trail – torque individually adjustable
-Turbo – up to 110 Nm
-Boost – up to 120 Nm for 30 seconds
-Walk Assist

Assistance levels can be easily tailored to your personal riding style via the Gobao app.

The BC201 handlebar display also features a USB-C port, allowing you to charge your smartphone or other devices while on the go.
