What eBikes is it compatible with?

Rim Magnet models have the speed sensor located on the rear wheel valve. If you're unsure what this is, contact us before ordering

If your eBike has either a Purion, Intuvia or original Kiox. You have a non-smart model (shop here)

Please note, this tuning kit only works on eBikes with 25-32kmh factory speed limit. Youth (20kmh) & Class 3 (45kmh) are not supported

What are the benefits of this product?

  • Easily set a custom max speed on your eBike up to 45kmh (28mph)

  • Once fitted all ride modes work exactly the same including 'walk mode'

  • Completely undetectable and can be switched on/off at any time

  • 2-year warranty included

Please note: with the chip active, speed readings are fixed above 22kmh. As a result, total distance recorded on the display/flow app will be less than actual distance covered when derestricted

How to avoid error codes

Unfortunately none of our tuning kits are guaranteed against error codes.

To reduce the risk of errors, follow these steps:

- Avoid updating the firmware of your e-bike. Updating increases the risk of tuning detection

- Disable automatic updates in the eBike Flow App

- Activate/deactivate the tuning before the ride (when the e-bike is standing still), not during riding

VOLspeed Smart is easy to install, you can take a look at the instruction manual here

Firmware Updates

Updating your eBike’s motor firmware may block or disable your tuning kit.

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.

Keep in mind:

✔ 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

If you’re unsure, reach out before updating. We’re here to help you keep your ride running exactly how you like it.

Volspeed V2 Works great on my 2025 Trek Rail 9.8 GX AXS Bosch Gen 5 Motor, I hope it’s the same after the 100nm 750W update, I’m so glad Trek stuck with the disk magnet it’s so much neater than the rim magnet solutions, I’ve been running Volspeed 4 on my 2022 Trek Rail for 3 years without one single issue so I’ve every confidence in this V2 for the smart system.

Great service and communication.
I bought 2 items one of which didn't work due to software.
I returned the item and another was sent out in quick time and the price difference was refunded right away.
I would definitely recommend this company and I will use them again.
Thanks

What a wonderful product,my Cube TM 160 was woeful to pedal on flat ground due to the weight and nature of the bike,it felt as if the brakes were being applied after reaching the 15 mph.Adding this to the bike now makes it feel like I’m riding at normal bike speeds out on the trails,which in my opinion is much safer when approaching jumps,obstacles etc at speed when you need maybe a couple of quick extra pedals.I would definitely recommend this product.
