What This Cycle Computer Tracks

The SY Bicycle Speedometer mounts on a handlebar and measures current speed, trip distance, total distance and riding time. A bright LCD shows the data clearly in daylight. It is built for road, mountain and folding bikes where a simple wireless sensor setup is preferred.

When the Wireless Upgrade Makes Sense

It replaces a basic wired unit or a phone app that drains battery and needs a handlebar mount. The jump is worth it when you want automatic wake-up on vibration, a backlight that activates between 18:00 and 06:00 on any button press, and no cable to snag or fray. Note that the device may not work with some electric-assist bicycles.

Installing the Sensor and Head Unit

Installation takes a few minutes with two buttons controlling every function. Pair the magnet to the spoke, align the sensor on the fork within the specified distance, then clamp the head unit to the bar. A slight rattle is normal and comes from the automatic wake mechanism. Customise the tyre size for accurate readings. Electric-assist compatibility must be verified before fitting.

Questions about this item

How does the computer mount to the handlebar?

The unit is designed for a handlebar mount and installs in a few minutes using the included bracket and two-button interface for setup.

What is the common mistake during installation?

Riders often place the sensor and magnet farther apart than the specified distance, which prevents the wireless signal from registering speed data.

When will the backlight need replacement?

The backlight activates automatically between 18:00 and 06:00 when any button is pressed and is built into the sealed waterproof unit, so it does not have a user-replaceable bulb.
