2. Secure the JClip:

Sports Shoes / Sneakers (Standard Shoelaces)
With the “J” logo facing toward the toe of the shoe, snap the JClip near the upper-middle section of your shoelaces. Thread at least two rows of shoelaces through the JClip to secure it firmly in place.

Cycling Shoes (Thin Shoelaces)
With the “J” logo facing toward the toe of the shoe, loosen your shoelaces and thread at least two rows of shoelaces through the JClip. Make sure the front shoelace is securely seated in the upper notch of the JClip, then retighten the shoelaces and snap the JClip closed to secure it firmly in place.

3. Attach JMotion Main Unit to JClip

Step 1: Squeeze the left and right sides of the JMotion unit (at the 3 and 9 o’clock positions).

Step 2: While squeezing, rotate the device 90° counterclockwise.

Step 3: Remove the JMotion unit from the band and insert it into the JClip.

Step 4: Rotate the JMotion unit 90° clockwise until you hear a “click,” indicating that it is securely attached to the JClip.

Step 5: Make sure “JACFIT” is horizontal and facing the toe of the shoe.

Troubleshooting Guide

Installation Tips & Common Issues

Sports Shoes:
Snap the JClip onto the upper-middle section of your shoelaces to prevent accidental button presses during rides, which may cause the JClip to pop open.

Cycling Shoes:
For shoes with Velcro straps, keep the JClip button clear of the straps to prevent accidental pressing during rides, which may cause the JClip to pop open.
Make sure the front shoelace is properly seated in the upper notch when attaching the JClip to the cycling shoe.

JMotion Unit:
The magnetic connection alone is not sufficient to secure the JMotion unit to the JClip. Make sure you hear a “click” to ensure the unit is firmly locked into place.
Make sure the "JACFIT" logo is horizontal and facing the toe of the shoe; otherwise, data reading may be inaccurate.

When the JMotion main unit is not connecting properly

1. Check if the JMotion main unit has enough battery. If not, fully charge and reconnect.
2. Ensure Bluetooth is enabled on your phone or tablet.
3. Ensure Bluetooth (Nearby Devices) and Notification permissions are granted for the app.
4. Avoid connection conflicts when changing apps. Close the previously connected app completely (swipe it away), then proceed to connect with the new app.
5. Before connecting, please tap JMotion main unit to wake up the device, then reconnect to the app.

*If the issue persists, please reinstall the app and repeat the steps above, or contact our customer support team.
