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

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.

Produit solide, bien fini, bien conçu et qui se fixe parfaitement. Un sans faute!

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.

Con questo fanale posteriore sono possibili 4 differenti modalità: - 1 e 2 sono due tipologie di lampeggio che funzionano in automatico (con sensore stop e spegnimento automatico se si rimane fermi); - 3 tipologia con lampeggio più intenso con sensore stop (rimane accesa non si spegne in automatico, consuma più batteria); - 4 luce sempre accesa con sensore di stop. Per capire lo stato di carica disponibile della batteria ci sono quattro puntini blu che lampeggiano (tutti accesi massima carica, 3 accesi 3/4 di carica, 2 accesi metà carica, 1 acceso 1/4 di carica). La luce è molto visibile e la durata della batteria mi sembra ottima (ho usato la modalità 3 per quattro ore e i puntini blu sono ancora tutti accesi). Io l'ho installato nel canotto sella e cosa molto intelligente, che molti altri fanali non hanno, è che in questo è presente un gommino che fa si che il fanale rimane orizzontale. Non posso che consigliarlo.
