JetsonSpark Training Wheels

These are very sturdy holding a max weight 198 lbs., has a rubber tire but the lights on the tires barely light up. For the price point and being delivered the next day is great. All the pieces, instructions included but you will need real tools to get them on even though they provided a small wrench.

Product shipped quick and was packaged well, we were super excited to put these on my son's big boy bike. However one of the wheels doesn't light up. Huge disappointment and I haven't heard back from the seller on a replacement. For now stay away from these.

They look like quality wheels but no hardware in the box...sent the wheels back.

My 6 year old son hasn’t mastered riding a bike yet without training wheels on and gets discouraged quickly so we decided to put the training wheels back on his bike only to discover we couldn’t find them. He’s been asking us to purchase him some so I was excited to see these being offered since these light up. Attaching these on his bike was rather simple. He has an 18” bike (I’m not to sure of the brand). The lights were already installed in the wheels and I don’t think they can be replaced because I didn’t see anything in the handbook about it but it’s not important at all. The quality seems great and they’re sturdy on his bike and he’s happy that he can ride his bike again. The lights go off when the bike is in motion. Definitely recommend!

These use some pretty cheap parts, but I suppose most training wheel sets do. Hopefully you won't need to use them more than a few weeks.Training wheels are something every parent has an extra set lying around, because you use them for such a short time. We actually picked up a pair at a garage sale for 25¢, but one of them got bent while in storage, and during the pandemic there were no garage sales and the thrift stores were closed. So we were happy to try out this pair of light-up training wheels.I noticed that someone else said theirs didn't light up - the ones I received work fine, but they are not rechargeable, I wonder how long they'll last. Also the light-up isn't as dramatic as the photos indicate.Mine arrived with one of the wheels missing a bearing - it had fallen out during transit. Not a big deal, just make sure to inspect the box for loose parts.My only complaint is that everything here is cheaply made - the metal supports are a bit thin, and the bearings are cheap and slow. Again, I don't think that's unusual for training wheels, if you want something nicer you'll have to go with trek or something like that.I think the price is a tad high at $25 - normal training wheels are $15ish, and I would hope the light-up kind would still be under $20.This is adjustable to fit kids bike sizes 12", 14", 16", or 20".
