DAWAY Rechargeable Bike Wheel Lights - A16 Cool Led Kids Bicycle Spoke Lights, 2 Tire Pack, Safety Hub Accessories for Boys Girls Adults, Waterproof, Super Bright, Fun Cycling Gifts

There are 2 functions, steady and flashing, with a bunch of colors. Getting them to fit the hubs took some patience, but they look great if you're trying to call attention to yourself on your bike at night.

The media could not be loaded. I like how easy it was to put on and how they gave you different size foam pieces to make it very adjustable for different wheel hub sizes. The colours are bright enough and look really good in the dark. I fully charged them so not sure how long the charge will stay. I think it said 12 hours it should last before recharge. They just clip on and off your wheel hub pretty easily.

Nothing comes close to this product. No wires no clips just attach and go!!

Great little lights! Haven't used them on the road yet but tested and and mounted these on my bicycle cargo trailer. Charge them a USB port. ( Package includes 2 lights and 2 USB recharging cords.) The lights open up with a thumb latch, you work it between the wheel spokes, snap it closed on the wheel hub, done. I didn't measure the max hub size these lights will fit but if you have an E-bike these aren't going to work. For smaller hub sizes they include plenty of spacers to fit. Fit great on my trailer. 1 button to turn it on and cycle through the different light modes. They seem pretty durable so if you have kids that have to take them on and off or change the color every 5 min they should take it. I like that it has one button operation but you have to push the button multiple times to get the mode you want every time you turn them on. No memory. I have a lot of lights on my bike and trailer. 4 headlights, 2 taillights and now 4 wheel lights. It takes awhile topush all the buttons to turn them all on and off. I'm almost 61 yrs old and feel a bit silly with the wheel lights but I want to be sure motorists can see me in the dark.

I ride a bike for work and these look great on it. They're more waterproof and rugged that I might expect. My only wish is that they had longer battery life. You get about 3 hours out of a charge if the lights are a solid color (longer if flashing). They're still pretty awesome, but expect to have to take them on and off a lot to charge them.
