How to Identify Your eBike Motor

To find the right tuning kit, first you'll need to know which motor powers your bike. Here's how to find out. Step 1: Find Your Motor Type Your bike's motor (sometimes called the "drive unit") is made by a company like Bosch, Shimano, Specialized, or Giant. To find yours: - Check your bike's app – If your bike connects to a phone app (like Bosch eBike Flow or Shimano E-Tube), the motor info is usually shown there. - Search online – Google your bike's make, model and year followed by "spec". For example: "Cube Stereo Hybrid 2025 spec". The motor will be listed under "Motor" or "Drive System". Common motors we see: - Bosch Smart System Gen5 or Gen4 CX - Bosch Gen4 (non smart system) - Shimano EP8 / EP800 - Yamaha PW-X3 - Brose Specialized 2.2 or 2.1 motors - Giant SyncDrive Pro2 Once you know exactly what motor is fitted on your bike. You can head over to our top picks section where we share all of our best recommendations for all of the most popular motors. Step 2: Not Sure? Let Us Help If you can't find your motor type or would prefer us to recommend the right kit, just send us the following via this form 1. Your bike make (e.g. Cube, Trek, Canyon) 2. Your bike model (e.g. Stereo Hybrid, Rail, Neuron) 3. The year of your bike We'll look it up and recommend the correct product for you. Optional step for Bosch Motors only – Check for a Rim Magnet If your bike has a Bosch motor as was manufactured after 2024, we also need to know if it has a rim magnet sensor. This is a small module attached to the rear wheel valve (or hidden inside the rear tire. Have a look and let us know if you can see one – this helps us recommend the right kit variant. Not sure what to look for? Here's what it the rim magnet looks looks like Need help? Contact us with your bike details and we'll recommend the right kit.

What is a Rim Magnet & How to Check if Your Bike Has One

What is a Rim Magnet & How to Check if Your Bike Has One From 2025, many Bosch-powered eBikes use a rim magnet speed sensor, and knowing whether your bike has one is crucial for choosing the correct tuning kit. What is a Rim Magnet? A rim magnet sensor looks like this. It's a small magnetic sensor attached to the rear wheel's valve stem. It works with a sensor in the motor to measure your wheel's rotation and calculate your speed. Why does this matter? A lot of eBikes from 2024 onwards are fitted with these sensors. They require a specific type of tuning kit. Our plug & ride kits will not work with this sensor. How to Check if Your Bike Has a Rim Magnet Step 1: Look at Your Rear Wheel Valve Check the area around your rear wheel's valve stem (where you pump air into the tyre). If you see a small black module attached to the rear valve, you have a rim magnet. Step 2: Look inside the rear wheel tire If you don't see a small black module on the valve, you may have an internal sensor as shown in the example on the right above. Rather than be visible on the valve stem, it's hidden within the wheel rim. Visual Guide Rim Magnet System: - Small module attached to the valve on the rear wheel (either outside or inside the rim) - Common on newer Bosch Powered bikes from 2024 onwards No Rim Magnet: - A physical magnet will be on the rear wheel spokes - Or, a rotor magnet will be found near the rear cassette - Common on older Bosch systems and Smart System bikes pre 2024 Which Bikes Typically Have Rim Magnets? Bikes WITH Rim Magnets: - Most Bosch Performance Line CX Gen 5 bikes - Many Bosch Performance Line CX Gen 4 bikes (from 2024) - Some Bosch Smart System bikes with Gen 3 motors - Most Bosch Performance Line SX bikes Bikes WITHOUT Rim Magnets: - All older Bosch powered bikes without Smart System Why This Matters for Tuning Kits Using the wrong kit type will not work - the kit is designed to interact with a specific type of speed sensor. Not Sure? Here's What to Do 1. Take a photo of your rear wheel (near the valve) and your chainstay 2. Send it to us - we'll confirm whether you have a rim magnet 3. Or share your bike make, model, and year and we'll look it up for you Need help? Contact us with photos of your rear wheel area and we'll identify the right kit for you.

eBike Software Updates

eBike Software Updates & Tuning Kits Before updating your eBike's firmware, read this guide to understand how it may affect your tuning kit. The Short Version Updating your eBike's motor firmware may block or disable your tuning kit. We recommend avoiding firmware updates unless absolutely necessary. What You Need to Know - Firmware upgrades can remove tuning compatibility - Tuning is only guaranteed to work with the firmware version available at time of purchase - A blocked tuning kit due to a firmware update is not covered under warranty Our Recommendation We recommend avoiding firmware updates – especially through service centres – unless absolutely necessary. Most updates are optional, and a working eBike doesn't usually need one. If your bike is working fine, there's usually no reason to update. Service centres may update your firmware automatically during a routine service, so let them know you'd prefer to skip the update if possible. Bosch Software Updates Our VOLspeed and Speedbox tuning kits for Bosch motors are fully compatible with the latest17.16 software update. However, we are unable to guarantee compatibility with future Bosch software updates. Bosch regularly releases new firmware versions, and any future update could potentially block tuning functionality. To protect your tuning kit: - Disable automatic updates in the eBike Flow app - Decline firmware updates at service centres - Contact us before updating if you're unsure Other Motor Brands The same advice applies to all motor brands including Shimano, Yamaha, Specialized, and Giant. Manufacturers regularly release firmware updates that can affect tuning kit compatibility. Always check with us before updating your firmware if you have a tuning kit installed. What If My Kit Stops Working After an Update? If your tuning kit stops working after a firmware update, unfortunately this is not covered under warranty. In some cases, we may be able to offer a replacement kit designed for the new firmware version (if available), but this would be at additional cost. Need Advice? If you're unsure whether to update, contact us before proceeding. We're here to help you keep your ride running exactly how you like it.
