Bontrager Ion 700 USB Headlight Review

Bontrager Ion 700 USB Headlight Review

Having a bright headlight is an essential tool for any road cyclist. Not only does it extend riding time in the morning or evenings, they can add an extra dose of safety during daylight hours.

And, that’s one of the great features of the Ion 700 — it’s annoying, blinky mode. It is pretty much like a flashing strobe light and it will get you noticed in the middle of the day. So, the good kind of annoying.

Aside from the blinky mode, there are fourĀ other modes of various brightness and another, irregular flash mode. Battery life varies between 1.75 at 700 lumens and 6.75 hours at 200 lumens.

Mounting the Ion 700 is easy. There’s only a single notch, so stretch that puppy and hook it on. It can be a bit of a pain to get it stretched and hooked in place, but once it’s there, it’s all good. For me, it had a tendency to rise upward during the course of a long ride — just a tad. The swivel mount is very nice and easy to adjust so you don’t blind oncoming traffic.

I don’t mind the white color, but some may not like such a bright color. The side-mounted orange lights are also nice for cross-traffic avoidance and they also illuminate the cockpit just slightly — an added benefit.
