Review on 🚲 Jetson Electric Bike Spark Light-Up Training Wheel Accessory | Motion Activated 4-Inch Wheels | Fits 12-20 Inch Bike Wheels | Durable Steel Brackets | Ages 3+ by James Julien

They use pretty cheap parts but I think most wheelsets will fit. Hopefully you won't have to use them for more than a few weeks. Training wheels are something every parent has a spare set of because you've only been using them for such a short time. We actually bought a pair at a garage sale for 25 cents but one of them was bent in stock and during the pandemic there were no garage sales and thrift stores were closed. So we were keen to try this pair of lighted training wheels. I noticed someone else said their wheels don't light up - the ones I have work fine but can't be charged, I wonder how long they will last. . The backlighting isn't as dramatic as shown in the photos either. My wheel arrived with a missing bearing on one of the wheels - it fell out during shipping. It's fine, but be sure to check the box for loose parts. The only complaint is that everything is cheaply made here - the metal supports are flimsy and the bearings are cheap and slow. Again, I don't think it's uncommon for training wheels, if you want something better you have to go hiking or something. I think the price is a bit high at $25 - regular training wheels are $15 and I hope the glowing option is still under $20. It can be adapted to 12", 14", 16" or 20" children's bikes.
