With a claimed maximum output of 700 lumens, the Bontrager Ion 700 RT front light sits at about the brightness you’d expect for a front light of this sort of price. This is more than enough for getting through nighttime commutes, even along the occasional unlit lane providing you know the roads well enough to know where the big potholes are to avoid.

The Bontrager Ion 700 RT comes with a choice of five modes: three constant with varying levels of brightness (700 lumens, 450 lumens, and 200 lumens), and two flashing modes (one standard and one irregular that’s sure to catch the attention of even the most inattentive motorist).

These varying modes also mean varying battery life, ranging from 40 hours on the irregular strobe down to an hour and three quarters on the highest setting – not too bad considering the compact body and the lack of external battery pack. Charging is also nice and easy thanks to the micro USB port, although the five hour charge time is a little lengthy.

The single LED light contained within a really compact body, that’s nice and light (pardon the pun), and easy enough to slip into your back pocket once the sun comes up and you don’t need it clogging up your cockpit.

The Sync bracket mount is also nice and secure, and I didn’t have any problems with the Bontrager Ion 700 RT moving when I hit potholes. However, the rubber strap that goes around the bars is far too short, making it a real struggle to attach to oversize 31.8mm diameter bars, while you can forget it if you’re running aero bars.

One nice feature is the ability to control this light wirelessly alongside other Bontrager lights using ANT+. This can be done through a Bontrager Transmitr remote (available separately for £49.99), which attaches to your bars and can control up to seven lights. Perfect if you want to look like a Christmas tree.

Verdict

The Bontrager Ion 700 RT is a good front light with a slim design for all but the very darkest of conditions. Offering a good selection of modes and decent battery life, it is great for winter riding and commuting. However the mount could be better and it takes a while to charge

    I just bought one of these and the mount can be adjusted. Loosen the screw and the hook will slide down. Its marked for different diameters. Slide it down to 31.8 and tighten the screw. It will actually go beyond the 31.8 marking a little bit. A lot of people miss that in the instructions.
