From the manufacturer

RoyalBaby Kids' Bicycles Cubetube

We believe our little riders deserve the best.

That's why we made our bike with premium material and technology. We use argon welding and four layers of coating paint commonly used in the luxury automotive industry. With these technologies, we make our bike meet not only our safety standard requirement but also its one-of-a-kind appearance and superb durability.

RoyalBaby Kids' Bicycles

Child- friendly ergonomics

Form follows function. Only a relaxed, upright posture enables children to optimally perceive their surroundings when cycling and thus provides the basis for safe driving behavior. The child-friendly positioning of the bottom bracket and the optimal distance between saddle and handlebars are further important factors for a child-friendly frame geometry.

RoyalBaby Kids' Bicycles

Specifically for kids.

The low frame entry and the low standover height enable young drivers to get on and off safely at traffic lights and crossings. This way, the feet quickly land on the ground again, which is a helpful factor, especially for inexperienced drivers. Wider training wheel legs provide more maneuverability during sharp turns.

RoyalBaby Kids' Bicycles

Futureproofing bike.

The bike has extra-wide tires and pedals, making it easy to maintain balance and ride even for young beginners. The adjustable stem and saddle make it futureproof for kids growing taller every day. Our exclusive seal bearing, shorter travel distance brakes, and durable steel frame helps toddlers learn how to ride and continuously improve their cycling skills.

Main Features

Kids' Bicycles Cubetube

Standard and child-friendly Caliper-brake

RoyalBaby child-oriented brake levers with a short lever distance for small hands. In our Cubetube models we use a standard and child-friendly caliper-brake on the front wheel. This ensures a good braking effect and ensures optimal dosing of the braking force so that the pilot comes to a safe stop. Our CubeTube models also have a coaster brake (pedal brake).

RoyalBaby safety handlebar grips with large baffles

Safety and child friendliness are key points of all Royalbaby bikes.Royalbaby safety handlebar grips with large baffles protect hands against injuries. At the same time, the safety handlebar prevent unwanted lateral slipping. The grip surface provides good grip and the small diameter is suitable for children's hands and allows a complete gripping.

Kids' Bicycles Cubetube

Closed chain box

Pinch fingers - impossible. If the chain is open, it can quickly happen that children are seriously injured by pinching their fingers in the chain. That's why Royalbaby always has a chain box on wheels for this age group. We care about the well-being of our children. In addition, the closed chain box also prevents shredded and dirty trousers or clothes.

" Daughter absolutely loves this bike and won't get off of it! I loved it because it looked different then the standard bikes do. It was a little bit more than other bikes but well worth the extra money. She is a little small for it, but has learned some tricks to get on it now (since she rides without training wheels). She likes the hand brake too which I switched to the other side because my daughter isn't a lefty. Came with all the tools to put together, even though I used my own, and just put those in my tool box. I would order this bike again, and will look at this company for future purchases. "

" Got this as a Christmas present for our 3.5 year old son (14" size). It's a perfect fit, with the seat all the way at the bottom. He'll be able to use it for at least a couple more years before he outgrows it. The bike was VERY easy to assemble - I (mom) did it myself in about 20 minutes. He's never ridden on a bike with training wheels before, and he got the hang of it within 10 minutes. Even figured out how to use both types of brakes (pedaling backwards or hand brake). This bike looks great and is a great value. I researched bikes for quite a while before deciding on this one. I am very happy with my purchase. "

The first RoyalBaby bike I got for my son was a 14” one, and it worked out great. A couple of years ago, we upgraded to an 18” bike, and he’s been riding it without any problems since then; he loves it! This bike is built tough—the frame is really solid, so it can handle all the rough play that comes with kids' adventures. This is our second RoyalBaby bike. Don’t worry about putting it together; the bike arrives mostly assembled, and finishing it up is super easy. The training wheels are fantastic for beginners, giving them the confidence to ride until they're ready to go on their own. With both front and rear brakes, stopping is simple and safe. I highly recommend RoyalBaby bikes. We’re thinking of upgrading to a 24” soon…

Pedal back ward to brake , not common in Singapore, pedal need to remain in same position to coast / free wheel. Pedallin slightly backward will brake the bike. For kids can be confusing. SEA shopper please be note advisory.

I bought this bike for my daughter, who just turned 6. It was love at first sight. This is a great kids' bike. First, it looks sharp - like a higher end road bike. The pink and the name "Buttons" say it's for a girl, but the look of the bike says it's still the real deal. Assembly was easy, though the font on the instruction sheet was way too small for my no longer young eyes. From opening the box to fully-assembled and ready to go took me about 20 minutes. I used my own tools, but the ones provided in the kit seemed adequate.As soon as my daughter saw it, she wanted to ride it. She's little for her age, only 3.5 feet tall. I bought the 16-inch wheel model, hoping she'd get years of use out of it. It's the tiniest bit big for her right now, she can only kinda get the balls of her feet on the ground when she's sitting with the seat as low as I can get it. But we took it out to the driveway, and she climbed on.And took off. The wide road tires give the little rider confidence, and the gear ratio provides a lot of oomph from pedaling. It's pretty speedy. When she went for her first turn, I was concerned about the supposed limited range of motion of the handlebars, but she made a pretty sharp turn (she was preoccupied with ringing the bell) with nary a problem. Now she wants to ride every day, and I'm going to have to buy a stupid bike, too, because it's hard to keep up with her now. Is that what this all is? A trick to get me to buy a more expensive bike for myself?Buttons is a great bike. I think they're going to be friends for a long time. And the bell is adorable.

This bike (purple with pink accents) was my daughter's Easter present this year, she is 2 years old and this is her first bike. Assembling the bike was easy although the directions are lacking full details. My daughter was so incredibly excited! Such excitement you'd think she had won the 2 year old lottery! She mastered ringing the bell immediately!!The chain guard and quality of the training wheels were a selling point for me. Also the bike pictured was exactly what was provided, no damage, and packaged nicely. Having both options for brakes is great too however all my daughter wants to do is try to peddle backwards which of course goes no where but we're working on that lol.

La bici es bonita, fácil de armar aunque muy muy pesada para que un niño pueda aprender a andar en bicicleta, más sin las rueditas de apoyo

Está padre la bicicleta, fue regalo para mi niño de 6 años. Llegó en tiempo y muy bien empacada, es fácil de armar; lo único es que mi hijo la va usar como un año y ya porque le va a quedar chica.

I've put together a few bikes and this one is the easiest and sturdiest I've ever encountered. Very reassuring. I like the way the height of the training wheels locks into place so there's no chance of them slipping up as pressure is applied through repeated use. I also like how the bike has pedal brakes and handle brakes. And I like the the gears and chains are completely covered (might be a pain if the chain ever slips, but I don't see that happening). I didn't even have to put on any wheels. I had trouble threading one of the pedals on, but eventually realized that one of them threads left, while the other threads right. I did peel off some of the stickers, they come off easily, but I kind of wish I hadn't because underneath, the finish of the pain is glossy, while the paint around where the sticker had been is matte.

I got the 12" white and blue version from Amazon Warehouse deals. It was in used condition, but the "used" looked like someone tried to put it together, got stuck, took things off, and sent it back.What I like:* The 12" size is a good fit for my almost 4 year old son, who is around 40" tall. He can comfortably reach the ground with the seat in the lowest position. This bike should last him for a year, or a little more, until he can get on his brother's 16" bike...* It looks well made. It's solid. The colors work together well, and it looks way better without every possible cartoon character printed on it.* It comes with the training wheels - a big plus, since you don't have to get them separately, and you know they'll fit. There also is a little bell in the box, the 3$ kind, but it's nice to have it.* It has a hand break, and pedal break. Not always a case with 12" bikes. I'm glad it does! My son does better with hand break under stress - he did not grasp the "pedal backwards" to stop thing yet.What I didn't like:* It's HEAVY. Is it heavier than other kid size bikes? No. It's not a $400 aluminum frame bike, either. But I cannot believe kids bikes have to be that heavy. The frame's profile could be half the size and hold up...* Hand break is a little flimsy, and adjusting the brake to actually stop the bike took some time and effort. It's there, tho, and it works now.* The "Buttons" band is a little confusing. We got two of the same brown plaid, and not sure how to change the design. I think it's unnecessary. I'd trade it for the water bottle offered in the other RoyalBaby model in no time.* The biggest problem I had with the bike was the rear axle, tho. It looks like the wheel was not in line with the frame. Not sure it was a manufacturing defect, or the first owner decided to adjust something, but it took a trip to a bike shop to figure it out. Amazon came through offering to take the bike back, or issue a partial refund. We kept the bike.Overall it's a nice bike. If you cannot stand Cars, Planes, Ninja Turtles and My Little Pony plastered all over your kids stuff, this is a good choice. I think it's a little overpriced, that's why it has the 4 stars. If I was choosing again I think I would pick , but we do like the bike, my son enjoys riding it, and since we fixed the rear wheel issue we've had no problems with it.
