Review Content works very well works very well on my trike with dogs pulling it. Awesome product I have mounted this to my velomobile and it is awesome. Great turn signals Easy to put on my bike and very visible from a long ways away. Easy to recharge, too. Well worth the money. I would buy this product again I bought 2 of these to use on our recumbent trikes. 1 for me and 1 for my wifes trike. Visibility is good for the cars coming up behind us. I had to create a rear mounting bracket to mount them to our recumbent trikes but other wise they work great. i would buy this product again the screw that tightens is of very poor quality,it striped before I secured it on the mounting bracket. safety first I bought this for my grandson who rides his bike home late at night. He has said he feels safer knowing cars can see when he is planning to turn or switch lanes at night. Great invention!!! Hey, I like this. It can make you safer. I bought two in case one is struck by a lightning bolt. It works great on the moped Used on moped. No bulky wires. Can be seen Clearly and easy to use. Only complaint cant be used as front directionals. Love it for the most part Love this for my bike commute, especially at night. Cant say enough good stuff about it, but I do wish the mount for the signal piece had more adjustment features. Its mounted to my back crate, not the bike frame, and the mount only tightens so much. I use a bungee to secure it better. Learned that lesson after my first turn signal fell off when I hit a pothole. But overall, I love this enough that Ive purchased two and have recommended it to friends and bike groups. This was a gift none yet Great Product Love this product. Just what I was looking for. Easy to install, charge, very visible. No complaints on any of the design. The one problem we had though, it didnt fit the frame of our bike. Our bike was made in Indonesia and thats where we want to use it. Perhaps the frames here are a bit larger in diameter. I dont know. So now we must find a way to attach the back piece. The controls fit fine. Perhaps in the future the back piece could be designed for bikes with a fatter frame. Great Product You can see it really well. Very easy to use. Adds another level of safety in bad traffic. The only downside is it must be charged often. Still a good product. do not work right open box, no instruction, not print on outside of box either, kind of simple, figure out myself, it is good while it was working, turn it on, it work, as I put it down on table it stop working, after 5 mins figure out if I turn it upside down it will not work, I shake it, can hear rattle sound come out, something is loose inside, which not suppose to, as it is for bicycle rider, will try another one, cause it is nice when it is working. Bike rider safety This was gift for my grown son who rides in traffic at times. However, he said both of his kids have been eyeing it so might have to buy more. ?? Great looking product but not substantially crafted. The wireless bicycle turn signal is a great idea; however the manufacturing of said device leaves a lot to be desired. The rear light has a plastic screw used to tighten the light to the bar...after 2 days it is already stripped. The device placed on the handlebars to activate the turn signal popped off and ceased to work. Safety first Gift Bicycle turn signal does not perform Enthusiastic about this turn signal device for my bicycle....however, after installing the hand device, it worked once and did not work again! The rear turn signal unit has a screw device to attach...after a few days, the thread wore out and the unit proceeded to slide down the stem of my bicycle seat. VERY DISSATISFIED. Christmas gifts for our "bikers" They look like a perfect gift. The kids do a lot of riding in the mountains, so this should be a great addition to their safety.
