Review: Feels nice and solid - lighting options good and brake light works!! - This is a nice little unit. I cycle mainly on track, which is floodlit at night. Even with the floodlights, I realised that it’s difficult to see other cyclists at a distance, so decided I should get done lights as a courtesy to others, so they have an awareness of my presence! This is a nice little unit, with a nice solid, quality feel to it. It comes with a choice of fitment - a fixed bracket which clamps to underside of saddle on the metal rails, or a mount with rubber strap to easily attach/detach it to your seat post. I went for the saddle mount as it is out of the way and looks tidy. A nice touch is that they provide a hex/allen key to fit the clamping bolts - Nothing fancy but it does mean you can fit it without searching the garage for the right size hex key! The main unit itself is a nice alloy construction and has a USB C charging port on the back. In use the unit screws on to either the saddle mount or the seat post mount. The thread is very fine so takes a quite a few turns to fully tighten it and there is an O-ring seal which keeps the water out from the charging port once screwed in. I can’t imagine it will come undone by accident in use. The different modes are good and accessed by pressing the metal button in the middle of the light - flashing; breathing (I like this one!); a fast triple (I think) flash; constant on. The accelerometer that’s built in appears to work well, so that when the bike suddenly decelerates under braking, the light comes on solid and bright and stays on for around 3 seconds. I can’t tell if it stays on bright all the time you are braking (like a true brake light on a car or motorbike would do) as I’m likely to fall off the bike trying to work that out. If I can find a friendly cyclist on the track at the same time, I might ask them to watch for me and let me know - I’ll update this when I find out! Basically it’s great value, feels decent quality and does what it says it does.
Review: Excellent light - great design, function and performance. - Unaccustomed as I am etc to reviewing kit - I will heartily recommend this light for all willing to lend and ear. Beautiful designed, beautiful light quality in terms of clarity, luminosity and colour (yes, seriously - wonderful shade of red), easy to attach (seat post in my case), easy to unattach, easy to recharge (USB cable), and easy to toggle between 4 light modes, and a handy indicator for battery strength (4 tiny blue leds for fully charged, counting down to 3,2,1). Plus I love the brake indicator - where it brightens strongly when firmly decelerating. I'm unsure about overall battery life, or replacing the battery (hopefully it'll be both long-lasting and easily replaceable) - but it's got me safely through the long, dark Winter months (Nov - Feb) - and hopefully many, many more to come.

### ⭐⭐⭐⭐ Nicely made, good quality.
*by T***O on 12 April 2025*

Nicely made. However - beware - if you are buying this for an electric bike - the clamp may well not fit the saddle frame. I managed to fabricate a fitting for my ebike and the light looks great and works well. The light does turn off and on automatically which is a plus - and the brake-light actually seems to work.
