Activ Life 2-Tire Pack LED Bike Wheel Lights with Batteries Included! Get 100% Brighter and Visible from All Angles for Ultimate Safety and Style

This product is nearly perfect and I hope you will get one or more sets as well! This green model is very bright, eye-catching, and a lot of fun to experience when the sun is down.At the time that I received this product I also had ordered the version that cycles through multiple colors. Both are excellent products and you will have to decide which is the right one for you. The big difference is that the singular color lights had two modes: On/Off — or blinking. I find myself appreciating the blinking mode a lot more often than I had anticipated and was disappointed that the color-switching one (while beautiful to behold) is only On or Off. You can read my review over on that model.As a (pre-pandemic) daily bicycle commuter, I found the side-illumination these afforded my tires to be invaluable for peace of mind. My rear-facing tail light and 1000 lumen headlight have long been staples BUT bicycling through an intersection always caused me to wonder whether the cross-traffic would notice me. Drivers are rarely on the lookout for cyclists where I live. I feel like these wheel lights changed my visibility to cross-traffic 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 still 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 and did not always feel like the wrapping was going well. It left me worried that I had or would damage them during the installation process. However, the material turned out to be remarkably durable 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. Or maybe it looks extra cool to have layering of the bulbs.The battery life on these are fair. In the cold weather they obviously take a hit but in general it seems like it would be 3 months of daily use in warm weather and 2 months in the winter. The usage period is likely longer but I have not kept very good track of battery life to report properly.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 OR 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. Expect there to be at least 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!
