If you’ve got an iPhone and don’t mind strapping it to your bars, then Wahoo’s bluetooth hardware can turn it into a decent bike computer.
The extra hardware, in the form of a speed/cadence sensor (£42), is essential however because although using the free, GPS-driven Wahoo fitness app alone is possible, its sampling rate is so slow that speed feedback is comically erratic.
Once the sensor (and the £67 HRM belt, if you want) is installed, however, your iPhone becomes a comprehensive ride computer. Data and maps can be emailed or uploaded direct to all the major training apps straight from Wahoo and battery drain is bearable too.
