Moshay Adjustable Adult Bicycle Bike Stabilizers Training Wheels Fits 24" to 29" - Quality Heavy Duty

The wheels are wonderful. I am an adult that cannot ride a bike and have some issues with balance. I rode my bike and had a terrible fall so I ordered these stabilizers. They were easy to install once I oriented myself with very limited tools. I installed them and went out immediately and I didn’t want to get off my bike. They are sturdy and great quality and I had no hesitation that they would hold my 175 lbs body. It gave me confidence that i was not going to fall over and when I did go too much to one side or the other the wheels held my weight so smoothly. I could go as fast as I wanted without issue. I lost a nut after a ride (I did not tighten the nut enough so my fault). I contacted the company and they were prompt, helpful, and quickly let me know what to order. This is a great company. Thank you for giving this 40 year old the ability to finally ride a bike!

The U-bolts are a good concept for allowing adjustments, but the nuts do not thread properly. When they get slightly tight, they skip backwards a thread. The tolerance in the threads are too loose. This allows them to slowly skip threads and loosen the whole thing. I had to retighten every 10 minutes. They also have bolts to add counter-pressure on the frame, but the holes for these were not machined properly. I was able to get 3/4 in with a lot of effort. One won't go it at all. Honesty, I'd look elsewhere for something like this.

Worth the money. My 14 year old is slightly delayed and has zero coordination or confidence on a bike. She's still using them after 2 months and I'm thrilled that she can ride with the rest of the family. Her bike looks like an adult 3 wheeler now and not like baby training wheels. I rode it once and it takes some getting used to if you are an experienced rider. You have to make wider turns, so account for that before plotting a route. Highly recommend.

Surprisingly not too hard to put together and very sturdy but not a lot of give! It was hard to turn and you really had to almost stop completely to make turns. Not great for a ride though the neighborhood but did provide balance.

Really nice sturdy wheels but the fitting is too small for my Velotric e-bike.

Functionality: As typical cheap Chinese crap- the u-bolts strip out when you tighten them. Will have to replace with American made steel.

Perfect for those with poor balance

Like several others have stated-the threads on the U-Bolts suck and jump threads when even tightened slightly let alone tight enough to use.
