Another new option for bicycle computers is essentially a display that mirrors information gathered on your phone. The most prominent example of this is the Wahoo Rflkt (£79.99) which uses a Bluetooth connection to stream information that your phones inbuilt GPS is gathering. It works with Wahoo’s own app, as well as Cyclemeter and Strava. You can also use it as a kind of remote control, skipping songs in a playlist or telling the app running that you’ve started a new lap.
There are limitations of course – mainly that your phone may actually run out of battery sooner than if you weren’t using the Rflkt, as you’ll have to keep Bluetooth on.
And remember, if you’re not that bothered about battery life, then you can always mount your phone itself to your bike, using one of these 10 Best Bicycle Phone Mounts.
