Dual-Sensor Exercise Bike Computer

This compact exercise bike computer integrates speed measurement and optional heart rate tracking via dual 3.5 mm female jacks located on its rear panel. It is widely compatible with popular home-use stationary bikes such as Sunny, L-Now, Pleny and Faafuu — covering an estimated 90% of domestic models. The unit operates on two AAA batteries (supplied) and features a sleek black plastic housing. No dimensions, weight or display specifications are provided in the original description. Heart rate functionality depends on the presence of handlebar-mounted metal contact sensors; compatibility may require minor rewiring depending on the bike’s internal wiring layout. Adapters are not included and may be necessary only in rare cases where the bike’s output ports are also female-ended. Package includes only the monitor — no mounts, cables or accessories.
