Review on 🚴 IronHorse Bicycles Bike Tracker by Martin Alvarez

Should be reset by pressing and holding the left button for 3 seconds, but actually a simple touch of the left button will result in a full reset with loss of all data. Cannot be mounted on the rear wheel, too far to transmit the sensor. Even when installed on the front wheel, the sensor readings are uneven; says my speed jumps from 12mph to 20mph when I'm probably stable at 18. . . Overall it is a useless product. Why can't I find a decent basic bike computer?
