Question: Is it good for a 5 year old
Document: My 4-year-old son has been using this for a few months now. He was previously using a smaller toddler-sized bike with training wheels, and I liked the idea of him learning balance without training wheels or pedals.The bike parts arrived packaged well and in good shape. Assembly wasn't too hard. However, I was disappointed that the handlebar height is not adjustable because the handlebar stem slides into the frame only a few inches and then will not go in any further.
We had a smaller wooden version of this bike and it was great. When our son outgrew it we purchased this one. It is a great way for kids to learn to balance on a bike. This is sturdy and well built and well worth the money. Our 5 year-old son rides it every day and has a blast. A great product.
We got this for our very unathletic 5 year old. We figured he'd be 25 by the time he learned to ride a two-wheeler. Instead, about 8-10 rides on this over 2 weeks, and DONE! He's got it! We just went for a 4-mile ride, and he was on his two-wheeler all on his own. I still cannot believe it. woo hoo!
The go glider makes it easy for our little boys to learn to ride a bike. They learn confidence and balance in a relatively short amount of time. Once I saw my 5 year old could balance on this bike, I switched him to a regular bike with pedals, and away he went within two minutes!
I bought this for my 5 year old grandson. He was terrified of removing his training wheels. After about ten minutes on his Go Glider he was confident enough to ride down our driveway, which is a slight hill. We removed the  training wheels from his bike and he just took off. I am very satisfied with the Go Glider. Great product for kids that are anxious about learning to ride on two wheels.
I got this bicycle for my 3 year old son as a christmas gift. The thought of running behind him for hours made me cringe. First I want to say thank you to the merchant that sells this bicycle (it is not amazon)!! They were so patient. Even if your child is tall for his/her age go with the smaller bike. unless your 3-5 year old is as tall as an average 7/8 year old the go glider will be too big !!
I purchased the 16-inch Go Glider bike for my 5-year-old daughter. I consider myself a pretty handy person, but I could not get the bike to work properly out of the box. Here are the issues I had with it:1. The front tire/wheel is molded plastic and at some point it must have been heated up too much and pressed because the wheel was uneven right out of the box. It didn't spin straight, you could plainly see it was warped.2.
We bought this for our 4yr old who is on the tall side but it ended up being a bit too large for him (our fault and not part of my review). The bike is of good quality and the dense foam tires are a good alternative to inflatables. We didn't like the foot rests much. They can swivel around to be put out of the way aligned with the frame, but when they are out they can get in the way of the kid's legs.
My kid doesn't crash the bike or throw it down or anything else out of the ordinary, but these handlebars just won't stay straight no matter how tight it seems I tighten that screw.The good part is my kid does enjoy using the bike and it seems to be a good size for him (he's above-average for height and weight at 4 years old). The seat is easily adjustable and sturdy enough.
Its a little tougher to ride for my 5 1/2 yr old than I expected so he doesn't love it yet but I know with more practice he will.
Answer: yes
