1~5mm
Magnet
Sensor
Secure the speed magnet on the spoke of the front wheel with screw. Make
sure the magnet side faces the speed sensor zone. The maximum distance
between the speed sensor and the magnet on the spoke is 5 mm. Once
above items in the right position, the user may go for a ride.
Note. Please make sure everything has been setup correctly before riding the bicycle.

2.5 Find out the wheel size

Wheel Circumference
To get the accurate result, the wheel size should be correct. Mark the
symbol on the tire and ride one circle. Then measure the length between
two points to get the circumference. Or the user can also get wheel
circumference by the following equation:
Circumference (mm) = 2 x 3.14 x R (inch) x 2.54 (1 inch = 2.54 cm)
R=Radius in centimeter
The user can refer the "wheel size chart"
on page 26 for the wheel size
