Installation Info (Read Before You Buy)
This tuning kit requires a moderate to advanced installation. Download Instructions here (PDF). It comes with three key components:
• Tuning module
• Replacement speed sensor
• Electromagnet unit
For some bikes, the motor may need to be lowered to install the electromagnet. The factory speed sensor is removed and replaced with a wired sensor, which is mounted to the chainstay.
If you’re not comfortable working on your eBike’s motor, we highly recommend having it installed by a professional bike technician.
Important:
To check what motor your bike has, see the sticker that is on or inside your frame. If it contains BDU code; 336, 334 or 332 you have a compatible bike. If your code is different, contact us for assistance.
