Smart Bike Tail Light USB Rechargeable Bicycle Turn Signals with Remote Control Rear Bike Light Waterproof Safety Warning Back Lights Bike Alarm for Night Riding Mountain

The product is not as bright as I would have liked for day use, but plenty bright for night use. The brake light functions fine, the real victory was fitting it to rear bike rack of Engwe bike. I had to cut, then bend a light flat bar of aluminum to attach to bike. The saddle and seat post attachment were no use to me as I often carry panniers and luggage on back of bike. Will update on light itself once I've used it for a while.

I don't know why I didn't get one of these sooner! It auto senses when coming to a stop. Multiple flash/strobe modes, easy to navigate modes, and when you brake it goes super bright. Great for cyclists behind you and for cars. The build quality is surprisingly good, almost a little too heavy - wished it was a bit lighter if anything. Two ways to install it, underneath the seat or on the seat post. Overall very happy with the product.

Il fanalino definitivo, lo uso in MTB cross country da 6 anni, installato sotto la sella, ancora perfetto, molto luminoso, si accende da solo con il buio, lo ricarico una volta ogni 2-3 mesi (ed io torno quasi sempre dai miei giri 1-2 ore dopo il tramonto uscendo una media di 3 volte a settimana), in alluminio molto resistente, si avvita sul supporto in modo molto sicuro, sono 6 anni che resiste a tutti i miei scossoni in MTB.

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.
