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.
