Bontrager's distinctive Apple-styled Ion light uses a very slim, white metal case with small orange side indicators for a hint of side visibility. The simple rubber hook mount with indexed swivel fits all round bars securely, plus less dramatically shaped aero cockpits, and the light slides on and off easily too.
The 700 lumen output gives good middle distance coverage and reach so you don’t need to compromise your back road riding speed after dark. The close in and peripheral lighting coverage has a real edge but there’s still enough light to keep potential trouble lit all the way up to your wheel or give you cornering context.
If we had to grumble about anything, the ‘B logo’ button is a bit stiff and hard to find with gloves on. Once you’ve found it though it toggles through three power levels and a flash option. The backlight changes colour as battery life fades too, making this an impressively practical, usefully powerful full feature light for the money.
