Sensor and Magnet Installation

Screw the magnet on the spoke. Then use zip ties to fix the sensor on the front fork by the same side of spoke magnet. Then, adjust the distance of magnet and sensor, and keep its relative position in 3mm (the smaller the batter, in the basis of not touching each other). The spoke magnet can work effectively while mounted on both sides of the sensor, but not works when it was attached to the middle of the sensor.

*Tips: The above values can be reset by press both “M” and “S” buttons for 6s.

Wheel Size and Circumference Chart

Enter circumference range: 0mm-9999mm, the Tire circumference can be measured in following way: firstly, turn the tire air faucet down to the ground, mark the corresponding ground. Next, push the bicycle into a straight line and make the wheel spin around, when the tire air faucet turns down to the ground, mark the second sign. Then, measure the distance between two signs, which is exactly the wheel circumference. If the measured value is 1.615m, you should input the number as 1615.

Common Problems

  1. No Speed Number on the screen:

Check if the table base is anti-loaded, the mental on mounting shoe should touch the mental on the bottom of computer.

  1. Different Temperature Figure:

The regular temperature difference is 1-3℃

  1. Speed Value Changes Frequently:

Check if the magnet spoke is target to either two sides of sensor. The frequently speed value change is always associate with the magnet spoke target to the middle of sensor.

  1. Manually Wake Up for the Wireless Computer:

The wireless computer needs to be wake up, but the cable computer can auto-wake up.

  1. Figures keep no change:

Check if the battery of sensor is well installed.

“+” means your speed is quicker than the average speed; “-” means your speed is slower than the average speed.

  1. Speed Value Faster or Slower:

Check the setting, usually it is related to the wrong wheel circumference or measurement unit setting.

  1. Not Applicable:

The bike computer is not applicable for motorbike or vehicle.

  1. Figure Missing:

The internal data of bike computer can be automatically stored; it won’t miss when it is no power.

  1. Buttons not work:
