Review on Stay Safe And Stylish On Your Bike With DAWAY LED Wheel Lights - Waterproof And Fun Patterns Included! by Alex Marshall

If you want these for an adult riding FAST around town and don't really care if the pattern is very visible then great. If you want them for kids bikes for riding around a campground or neighborhood at normal kid speeds to show off, then you would be better off getting lights that didn't flash or change patterns. A solid light on the spoke would look cooler than the flashing, changing patterns. If the patterns were held on for more than a fraction of a second, you would MAYBE have a chance to see it as the kids rode, but unfortunately they flash too quick to really see any pattern at a normal kid speed (I'm talking an 11 yr old going as quick as they can on a flat road). And unfortunately, there is no option to change the speed of the flashing pattern so that the light is held on longer.
