The Kickstarter founded See Sense 2.0 Rear LED combines sensor technology with great functionality to make riding safer for cyclists, whether night or day. We’re big on tech and safety at Bikmo, and have been really appreciating the variety of Kickstarter bike safety related products coming out from all over the world.

Born out of Northern Ireland by founders Philip and Irene McAleese, See Sense aim to be the leading global cycling technology company, and given their first foray with the See Sense LEDs, we thinking they may be onto something. We first met the See Sense team at the London Cycle Show 2015, where we were given a See Sense 2.0 Intense to put through it’s paces.

See.Sense 2.0: Tech review

First impressions

The light feels solid, well built and there’s a distinct lack of buttons, which isn’t a bad thing. It’s quite square in shape, which being a design geek I think could be room for improvement, but the proof is in how it works and whether it does the job it’s set out to do. The rubber strap which attaches to bars/seat-posts is chunky and solid, a key element that cheaper models fall down on.


This is where the interesting stuff starts. It contains an accelerometer and a light sensor to increase the brightness and visibility when you need it most i.e. braking, when a car is approaching from behind, as well as going over rough ground etc.

To switch it on, you rock it from side to side – the first couple of flashes indicate the battery level, then there’s a warning light, then the LED starts and by god it’s bright. Our version is 125 lumen, which is super bright making it visible in daylight too – great for city riding.

You then leave it to do it’s magic – it’ll alter the brightness and frequency of flashing based on signals from the accelerometer or light sensor. To switch it off, you just put it face down on a table and it’s off in a few seconds. It’ll even go into sleep mode if you’re stationary after 3 minutes to save battery – which by the way lasts up to 12 hours.

Charging is simple, with a mini USB port on the side which can be plugged into a computer, phone charger, car and you can even tweak the brightness settings.

On the road

It sits solidly on the seat tube, and after I’d secured it I completely forgot about it and had to be reminded when riding with a local club and other riders noticing the changing brightness. It runs long enough for me to leave it a week between charges, though I was once caught out on a group ride so make sure you know what battery level you’re on.

The only small issue I had was the the rubber strap  – it isn’t so well bedded into the hoops so I’ve mislaid it a couple of times – again perhaps a tweak for the next version.


It’s a superb piece of tech that feels solid, is uber bright and worked flawlessly. There’s a few tweaks to be made with the rubber strap and aesthetics, but it’ll definitely be on my bike throughout the year. Oh, and I like it so much it’ll soon be available in the Bikmo Shop – until then, check out the See Sense Online Shop.
