In this blog post we explain how you can derestrict your eBike fitted with a Shimano motor using a tuning chip. Before we start, please note that removing the speed limit on your eBike can void your warranty. eBikes with the speed restriction removed are illegal and only for use on private land.

(last updated January 2025)

Step 1: What motor do I have?

Before you jump in to ordering any tuning chip. You need to know exactly what Shimano motor your ebike has. Shimano has many versions of its motors so it’s important to check first.

Google is your friend here. Search for your exact ebike make, model and year and check the specs from any reputable ebike shop.

Here’s a breakdown of the main Shimano motors:

EP8/EP800 - Shimano’s high powered 85nm motor found on many of the flagship models from 2022 onwards.

E8000, E7000, E6100, E5000 - These have been around from 2016. They share the same internal systems and ports. The only difference being the power output and weight.

EP801/EP6 - This lightweight and more intelligent EP8 (EP801) system offers controllable high-performance power to provide that natural ride feeling on the trails. Commonly found on 2024/25 models.

Step 2: What ports do I have?

If your bike has an EP801 or EP6 motor, you can skip this step and go straight to step 3.

Okay, so you’ve managed to find what motor you’ve got. Congrats, you’re one step closer to derestricting your ebike!

Next job involves a bit of manual labour. You’ll need to do this anyway to fit your tuning chip so get the practice in now.

Remove your motor cover to check the ports, you’ll see something like this:

As you can see in the example above, there's one spare port in the middle. If you have the same setup you will need the “standard” version of any of the tuning chips we recommend below.

If your motor doesn’t have a spare port, it will look like this example below.

For these, you’ll need the “+ETP” version of any of the tuning chips we recommend below.

Completed Steps 1 & 2?

Congrats! Nearly time to crack open a cold one, you’ve almost completed the mission. Now it’s time for the fun part…

Step 3: Choosing your Tuning Chip
