Brightz WheelBrightz LED 自転車ホイールライト ブルー タイヤライト2個パック 2021年 クリスマス 靴下の詰め物&クールなプレゼント 7歳 8歳 9歳 10歳 11歳 12歳 男の子 女の子 ティーン 息子

Had these for a few weeks. Very bright and great for riding at night. Will buy again for the back wheel.

I love wheel lights! The fun, colorful, decorative lights are playful, and the safe practicality of being clearly illuminated from the sides is an actual life saver. So, when my last wheel lights stopped working I knew it was an easy decision to replace them. I purchased and installed my new lights and headed out for my commute. Two blocks from home, I heard a freaky clunking from my wheel and pulled over. Somehow, the battery pack came unstrapped, snapped the wire, and made its way out from my spokes. Tracing back the trail of pieces behind me, the case cracked open, lost the fresh batteries in a pile of leaves, and the battery box door that had broken off was almost immediately run over by a car. Though I was supremely thankful nothing got lodged in my wheel to take me out in traffic, it was still an intense start to a Monday morning. Unfortunately, I didn't even get to use my new lights once before they were toast. I proceeded to spend the rest of the day replaying in my head what happened and what could have gone wrong since the battery box was snapped shut and properly strapped to my spokes, right? It wasn't until I returned home that I saw the broken piece of rubber strap laying on the ground. Presumably, sometime between installation and my commute, the strap had snapped, leaving the battery box to fly off once I started pedaling hard. If I didn't see the rubber piece I would have never even considered it since, in all other respects, it's a pretty hardy strap. I shared this with Brightz directly, and even after a follow-up email from me, I never received any acknowledgment. Take that for what it's worth. I'm just thankful I lived to tell the tale. Check your straps, turn your lights on, and be safe out there, cyclists.

My son put these on himself and he is 10. They are bright and will help on darker mornings and evening time for bike safety

Hi Amazon Shoppers , Summer is closing to an end and the cycling nights are getting few and far between .I have to say this was the best summer of bike riding for me mostly due to these amazing lights . I wasn't at all familiar with them until my wife spotted them at an outdoor market .I blindly agreed to the purchase because they sounded fun and boy are they fun .Since buying four sets that day I came to Amazon and bought six more .I had to have a set for my new bike and pet trailer and I like them so much I got a few on the shelf , just in case .That set is still on the shelf and it doesn't look like I will be using them anytime soon because these are a quality built product not at all flimsy or brittle . The heavy-duty battery box is an awesome piece of engineering I think ,This is designed to clamp to your spokes and it does just that by means of an x shape configuration molded into the box and a slide plate that is unscrewed to loosen and tightened down to lock it into place once you have it into position , The back of the box is screwed on so you know your batteries aren't going anywhere until you are ready to put a fresh set in After the first set I was slapping these on in no time at all . The well-insulated wiring also plays a role in the durability of these lights .It's not a bare copper wire and it has a nice thick coating of insulation running to a larger clear section of PVC tubing .A simple but effective design ,The tubing itself pushes right into a 26-inch wheel perfectly and the thickness of the tubing actually secures it into place . On my fat bike I was a bit leery at first but once I started lacing the lights through the spokes they fell right into place and the thicker PVC tubing helped to hold them into place .I cut mine down a few inches so I would have a seamless ring of lights and I am glad I did because they look amazing .I had people from all ages yelling I like your bike and cool bike all summer long. The battery life is excellent.I rode pretty much every night for 12 to 20 miles and hang out at the park while I'm on my bike and haven't had to change my batteries once ,There still as bright as the day I bought them too . I will update with better pictures tomorrow but for now heres a few that I have handy. Thanks for reading .Happy cycling.

I run this on an aluminum cyclocross bike that I use for 10 mile commutes, often at night. Been using these for approx 2 weeks. Some notes: Pros: -I can definitely vouch for it's water resistance. I had to bike 15 miles home yesterday through a torrential thunderstorm (the sort that soaks you through within the first 20 seconds) with these on. There were also long flooded sections of path where my tires were completely submerged. The lights were on and stayed on throughout the ordeal. Checking the next day to see if any water might have seeped in overnight, nope, they still worked. -The materials seem sturdy. The battery case is a thick plastic and LED strip is encased in clear plastic tubing, so it offers some protection and resilience vs any debris you might hit. -Looks sweet and attracts a lot of positive attention. Neutral considerations: -I've only had these for a total on time of roughly 10 hours, so I can say that a set of batteries can last at least that long -I'm a little concerned that the heavy-ish battery pack would negatively impact my wheel balance. I've taken my rig up to 37 MPH on straights without feeling any negative feedback or vibrations, but I'm still apprehensive about doing fast turns. Cons/Improvement suggestions: -Ease of replacing batteries. The battery casing is held shut by four screws, which is a bit of a pain to open (especially once the pack is already secured on your wheel). Would be nicer if it used some sort of tab/locking mechanism instead -More versatile mounting options. The provided mounting mechanism seems to be designed towards wheels with many spokes that cross over. My wheels have a lower spoke count, those of which are spaced farther apart. My front wheel also doesn't have any points where the spokes cross over, and the angle of intersection between my rear wheel spokes was too high to be compatible with the bracket on the battery pack, so I had to use a bit of creativity (and sandpaper) to secure them. In conjunction with my earlier comment regarding wheel balance, it would be nice to have an option to mount the battery pack on top of the wheel hub, closer to the center of gravity of the wheel. All in all, I'm liking my Tron bike, and will hopefully update this review as I put it through more trials (battery life, subzero Wisconsin winters, general longer term durability, etc) Update 5/17/2018 -Battery life is as long as advertised. -A few more episodes of wading through deep water (some water might get stuck in the tubes afterwards, but trickles out eventually). Two Wisconsin winters later. Still working and holding strong. -Pressures you to pedal harder when on, because cool bikes don't go slow.
