The Betty R14 is not cheap, but it’s the most adjustable and easy to configure light on test.

>>> The best mountain bike lights

What makes it so simple is the new Lupine Light Control app (free to download from the Apple Store) that lets you connect it to your smartphone and take full control over all the settings.

The R14 comes preset, but by using the app you can add or subtract settings and fine-tune the lumens and run time. On the trail you then use the wireless remote to toggle through these different modes.

This remote is the only one that integrates fully with the controls on your handlebar, and even has a raised section so you can overlap onto a shifter pod. It also mimics the headlight by changing colour when switching between modes.

All Lupine lights currently come configured for helmet use, but you can order the Betty R14 with any size bar-mount for an extra £20.

On the trail there’s a lot of light thrown quite far out, but with a more diffused spread close in. It’s a little focused in the centre, causing a bit of bounce back when zipping through dense vegetation, but it only takes a second to re-map for closed-in trails.

What sets this Betty R14 apart from the competition is, not only the whiteness of the light, attention to detail, and quality, but its usability. Yes, £750 is a lot, but if you want the best out there, this is it.
