easier than we thought to install . good durable wire string and stays bright longer than the 40 hours stated in description.

Perfetto , l illuminazione dura tanto

I got these for my grandson's bike. His mother installed them. They are so pretty!

extremely difficult to attach to the hub unless you have tiny hands of a toddler! My hands hurt. still not attached.

I bought three sets of these for my trike 7 years ago and only recently did one string stop working. So I reordered the same brand since it lasted.for so long. And these get used almost nightly and are exposed to wet weather and mud puddles. These lights are better at making me visible to traffic more than reflective gear or a headlamp. And kids enjoy how colorful the wheels are, they say it looks like a parade.

Üründe akü vs yazınca daha kapsamlı bir beklenti ile almıştım. Akü denilen ürün pil kutusu imiş. Noel tatili olmasına rağmen 15 gün içinde geldi. paketleme ve kargo güzeldi. Ürün kaliteli ancak pahalı. Daha ucuz olsa tercih edilebilir bir ürün

★5個にした理由は……皆さんに、レビューを見て頂きたかったからですm(*_ _)m絶対に買ったらいけない商品!!!!子供とお友達用に購入しましたが……2つ共に、5日もしない間にパーでした(;｀O')o

Bonjour, je recommande fortement ce produit, ça rends très bien et semble être solide. L'installation est facile mais longue, comptez une heure pour être large. Pensez à en prendre deux (un pour chaque roue)

I ordered 4 sets of the Activ lights for my kids' two bikes. 3 out of the 4 sets worked -- one of them was defective. We had great customer service, as a new set was sent to replace the defective one (which simply would not turn on). The replacement set took a while to arrive, as it was on backorder, and my daughter wanted to wait for her preferred color. No big deal. It arrived and worked perfectly. We now have really fun lights on the bikes, which is nice for evening/dusk bike rides, to attract more attention to the kids' presence, and also just for fun, as they look really cool. Installing on the smaller bike wheel was a bit of a pain in the neck, as there is simply not a lot of room to work your fingers towards the center of the wheel to affix the battery pack/component. There's really nothing to do to get around this aspect -- if you want bike lights, you just have to put in the labor and have some pinched fingers for the duration. It was a lot easier to install on the larger bike wheel, as there is more room to maneuver, and the larger bike wheels were really easy to affix the battery pack to. After affixing that battery pack, you simply wind the lights around -- we followed directions, and it's just a little time consuming, but again, worth it. Really fun product, and we are happy with the buy. Would recommend!

I thought for that price i might as well give these a go and they were way above my expectations. A lifetime warranty too. They're really easy to install and once on the light up the night making me feel soo much safer. Add to that they look great too. I was soo impressed after only one use ivery brought a set for my back wheel too!

This product is nearly perfect and I hope you will get one or more sets as well!At the time that I received the wheel spoke lights I also had ordered the version that is a singular color. If I had not done that, then this review may have been given the 5* rating. Both are excellent products and you will have to decide which is the right one for you. But let's talk about the nuances.The color-changing product is truly beautiful. It runs the color gamut from Red->Green->Blue with a few colors in-between as well. However, there is only one mode: On/Off. I appreciate that with the single-color model I received it can toggle between solid color and flashing. This product does not flash which is about 50% of the star I removed for the overall review. It also does not have a quick cycle mode. The only mode available is SLOOOOW color changing. This is fine and beautiful to watch, but I would have appreciated a quick color change mode -- maybe 4 seconds to cycle through all the colors rather than 10 seconds.As a (pre-pandemic) daily bicycle commuter, I found the side-illumination these afforded my tires to be invaluable. My rear-facing tail light and 1000 lumen headlight have long been staples but bicycling through an intersection I always had to wonder whether the cross-traffic would notice me since drivers are rarely on the lookout for cyclists in my area. I feel like these wheel lights changed the game for me in a big way and I was very pleased to have them on anytime I was out pre-dawn or post-dusk. I even appreciated using them in flashing mode under the presumption that they may just give a little more visibility during the morning or evening commute when the sun was up.The installation process isn't ideal and I found it a little more difficult and worrisome than I had pictured. I found the tiny bulbs (like regularly-spaced dew on grass) to get in the way of twisting around my spokes. It left me worried that I had or would damage them during the installation process. However, the material turned out to be remarkably durable from what I could tell and I was grateful that my 700C wheel fit the product perfectly for one trip around the outer rim. If I had a smaller wheel (or wanted to install on a kids bike) I imagine the number of trips around would feel tedious and a bummer that there aren't shorter versions available.As the battery life starts to taper down I noticed that fewer colors were illuminating through the pattern cycle. It has been a long time since I changed the batteries so at least the product is still usable several months into daily use - kudos! I'm hopeful that when I eventually do swap out the batteries the rest of the colors will appear as before.Regarding maintenance, if you get your bicycle tuned up, these little lights will likely have to be worked around as the bicycle mechanic trues the wheel spokes and if you hang your bicycle by the wheel, they will likely be an annoyance to you. But there isn't any interaction with the lights (hopefully) when changing a tube. It feels like once they are installed they pretty well stay where you put them. I've had a few times where I wished that the lights were capable of being more cemented in place but in general I haven't messed with their positioning along the spokes. Expecte a little movement, though, from where you install them.So yeah, I am a huge fan of the bike wheel spoke lights and I can only hope that the innovations will be able to continue and keep this product improving as it matures. Great work Activ Life!
