E-SPEED S2.1 Tuning for Shimano EP8

What is e-speed?
e-speed is an electronic module that allows you to unleash the original performance of your electric bike. When installed, the 25 km/h (15.5 mph) assist limitation is removed, allowing you to enjoy a smoother and more powerful pedaling experience, limited only by your own cadence.

How does it work?
Most mid-motor electric bikes stop using electric assistance at 25 km/h (15.5 mph). With e-speed, this limit disappears, and you can reach higher speeds while maintaining motor assistance. Installation is quick, and the module remains permanently activated.

Can I install it myself?
Yes. Thanks to the use of OEM connectors, installation is simple and can be done at home without advanced technical knowledge.

Is it reversible?
Yes. The module can be removed at any time, returning the bike to its original state without leaving a trace.

What motors is it compatible with?
e-speed is available for all major mid-motor systems on the market, including Bosch, Yamaha, Shimano, Brose, and others. Make sure you choose the right model for your system.

Is it legal for use on public roads?
In some countries, e-speed is intended exclusively for private use or competitions. The user is responsible for complying with their country's regulations. Carefully read the instruction manual and the legal notice for its use.

Does it require maintenance?
No. Once installed, the module requires no adjustments or maintenance. It is designed to last and withstand adverse conditions.

Does it affect range or the motor?
Battery consumption increases at higher speeds, but the module does not alter the internal workings of the motor or overload it. It is a safe and non-invasive solution.
