Airwheel 2.9" Wireless Bike Computer

The Airwheel JH-TOOL-0013-CYFIE is a compact 2.9-inch wireless cycling computer designed for riders who want clear speed, distance and time data without handling a smartphone on the bars. Its IP54-rated housing and green backlight make it readable in rain or after dark, while the handlebar mount and two-button layout keep operation simple for daily commuters and weekend fitness cyclists alike.

Upgrade from Basic Analog Speedometers

Riders moving up from a simple mechanical odometer or a phone app gain 22 selectable functions including auto wake-up, customisable tyre-size calibration and a wireless sensor that pairs within a 60 cm range. The jump is worth it when you need reliable, cable-free logging that survives splashes and does not drain a phone battery, yet you do not require GPS mapping, heart-rate pairing or structured training plans.

Sustained Ride Behaviour

During long rides the LCD remains legible in direct sun and the backlight activates cleanly for tunnels or night sections without flicker. The wireless link stays stable as long as the sensor-to-computer gap stays under 24 in and the magnet-to-sensor gap stays under 3 mm, so consistent mounting is the only maintenance the system demands over months of daily use.

Questions about this item

What handlebar diameter does the 12.9032 cm tall mount fit?

The mount clamps to standard handlebars and the 12.9032 cm tall unit sits on the supplied bracket; no proprietary bar size is required.

Which step do installers most often get wrong when pairing the sensor?

Keeping the sensor-to-magnet gap under 3 mm and the sensor-to-computer distance within 60 cm; mis-aligning either breaks the signal.

What user-replaceable part will need attention first?

The wireless sensor and the head unit each run on a button cell; replace the cell when the backlight dims or readings drop out.
