Bike is an amazing. My kids had been struggling with a heavy bike after having mastered a balance bike and was regressing. 10 minutes on this Belsize bike and she was cycling! Customer service was also prompt and efficient. I wrote in after I placed my order to try to correct a wrong address, they fixed it right away!
Purchased 20" bicycles for my grandchildren on their 5th birthdays. Flawless delivery and support/service!
I purchased a 20" Belsize bike for my daughter a few years ago and it's been great. I liked it so much that I just bought another for my son. They are well made, and my kids have loved them. The combination of the aluminum frame and belt drive are really perfect for kids bikes. The lightness of the frame make riding so much easier for kids still building confidence on the bike and the belt drive is simple, and essentially maintenace free.
Very responsive customer support!
I purchased the 16” belsize for my grandson and very impressed with the bike. He loves riding it and I just purchased the 20” for Christmas as the next step. Again, the shipping packaging is superb, the quality of the bike is impressive, and the simplicity of the assembly wonderful. They include all tools necessary and, for anyone who knows bikes at all, it is easy to complete the assembly. I really like how adjustable it is and how much like an adult bike it is. I only wish they made a larger option so I could plan for his next bike after this one. The only thing I wish it had was the kickstand. On the 12” and 16”, the kickstand isn’t much of an issue because they start with training wheels and it is easier just to lay it over. However, the 20” is where it should be included. I did buy the optional kickstand for it, just seems like it should be included. Also, I wish they still sold the stem riser for the handlebars so the usability could be extended. But, they did provide the information to purchase the riser, so all good. As a belt drive bike owner myself, I’m glad to see a good quality belt-drive bike to start them out.
Amazing bikes: we have two children, and we own 12-inch balance bike, 16-inch, and 20-inch bikes.They are extremely light, and the kids love them!We bought the first one in summer 2021, it still looks and rides like new.Bonus points: it takes about 10 minutes to assemble them.Highly recommend them to everyone!
Great bike at a great price !
Great communication, ordered the bike that was out of stock but was promptly notified would be shipped out shortly and everything went to plan. Great service and quality
We recently ordered the 20” bike for our son. After a week and not receiving a shipment notification I reached out to the company asking for an expected shipping date as we really wanted to receive the bike before a family camping trip we had planned in a few weeks. They promptly responded and stayed in contact with me via email letting me it was in presale and when it would shipped, and when to expect it. I couldn’t ask for better communication and customer service! And our son loves their bikes! He's got a small build so he can handle this bike so much better and tackle hills with how light weight it is!
We were missing a handlebar screw, customer service was responsive, prompt and courteous. 10/10
Amazing customer service! They checked in multiple times to make sure the bike was to our satisfaction.
My oldest son rode this bike for 3 years. He finally handed it down to my younger son this year. One of the crank arms had become stripped and the pedal would not stay attached. I looked everywhere for an aftermarket part and could not find anything small enough. I thought I was going to have to buy a new bike. I reached out to customer service to see if I could get a replacement crank arm and Harper helped me get the correct part and expedited the shipping to have the bike all ready just in time for summer break! The bike is still in great shape and should last a few years with my younger son before passing it on to a younger cousin! This company has amazing customer service!
The Belsize team is awesome! I was so happy to discover the the quality of their customer service matches the quality of their bikes.
Bought the 16" for my 3y old, then the 20" when he turned 6y recently. I credit belsize bikes for a lot of my son's physical agility and development. The super lightweight, two brakes, no coastal brake, and ability to install hand bar raisers made this choice our best investment so far. What a success. Beats competing brands on a heartbeat including woom. Lost a bolt a got immediate customer service and received the part in no time.
I had gotten this bike for my son and he loves it! I was weary of the belt drive having never seen or used one myself. The belt had broken over time and reached out to the company and they were very helpful with getting me set up for replacement belts and they arrived fairly fast as well! Been biking all of my life and still to this day and love passing that tradition on to my children. Again was not completely sold on the belt drive idea, but this are wonderful bikes! Having rode this particular bike myself as a grown man, I can say the belt drive is very nice and I'm sold!
The 16'' bike is high quality although the hardware will rust in areas prone to it. I sprayed some corrosion control on it and have no problems. Its light weight and very easy for my 3 y/o to ride. He figured it out within minutes after only riding a 8'' strider bike. One of the bolts came loose/lost and the support team was extremely helpful and sending me one of their special bolts. We will be buying the 20'' bike when the kids are big enough.
My son transitioned easily from a balance bike to his new Belsize belt-driven bike. He was zipping around within minutes. Customer service is very responsive and helpful, if you need any help along the way.
Excellent client service. The bike is really impressive due to its very light weight! I love the bike, the drive system on the Belt-Driven is great! My daughter is happy with her new mint colored bike.
Belsize bikes look good, have kid-friendly geometry, and include quality components. Just bought two of these (a 16” and a 20”) for my 6yr old and 8yr old. Paint job on the bikes is excellent. After being on balance bikes, moving to the Belsize was a great choice. Each kid picked up pedaling within a day or two. This is where the geometry matters — seat height, reach, and wheelbase are suited to help kids feel stable. While weight is not technically a matter of geometry, I think of them together, and the weight of these bikes is perfect for kids — these bikes are very light and easily maneuvered by kids. Picking up the bikes after a fall and/or walking the bikes around is no problem whatsoever for either of my kids. Importantly, the brakes are kid-friendly: levers fit kid-sized hands, can be squeezed easily, and are Tektro brand (which is a legit component manufacturer).Assembly was mostly already completed right-out-of-the-box, with remaining tasks (front wheel, handlebar, and seat) being relatively painless and quick. Attaching the belt-guard (i.e., chain-guard) was tedious, and I ultimately elected to NOT attach it. It is functionally unnecessary (after all, high-end mtb do not have guards), and the bikes work just fine without the guards in place.Any misgivings about a belt-driven bike ought to be shelved. I see no problems so far and do not anticipate any. The belt is made by Continental (a legit manufacturer for motor vehicle belts and tires, and also bike tires). My guess is that the specs on this belt are intended to meet repetitive cycling under loads similar to what a small engine would require. I’m not worried in the slightest, and I cannot imagine that changing/replacing the belt would be very difficult IF such should ever become necessary.Shipping was prompt. Unfortunately, one bike was missing an important bolt (for attaching the seat). Belsize was prompt in responding on this matter and provided the size for the bolt, along with a refund to cover the cost of the bolt (which I was able to obtain from my local hardware store with no trouble).
This is my son's second bike from Belsize. He recently out-grew his 16" bike, and we got him a 20" one. We picked Belsize primarily because of its light weight. He had another 16" bike when he first started learning, but that was too heavy for him, and he didn't want to practice with it. Yet he 'mastered' riding bikes the second day on a Belsize bike :)There was a little hiccup with our second bike. Everything was great except that the box came with 2 right pedals. I contacted their support email and Shirley was great. She sent me a left pedal and now my 7 yo is happily riding his 20" bike.
