1. The Best Balance Between Performance and Folding Size


The 20″ wheel size is often the best balance between performance and folding size. With this wheel size, your bike can perform exceptionally provided it uses a smart frame design and component choice. The 20″ bikes will also fold to be less than 200 litres making them easy enough to get onto any form of transport.


2. Basalt Brake Surface


Assure the rim to well anti-heated for long time riding, to increase braking performance and durability, and greatly improve the braking performance of the wheelset in rainy days or wet conditions.


3. Painting and Decaling Service


We accept custom decal and painting design work. We also have professional experience decal designer to help you finish your design work.


4. Folding Bikes and Children’s Bikes Compatible


We also provide wheel assemble service, but only for wholesale. Please feel free to contact with me about wheels details. Thank you very much.



Guide to Kid Bike Sizes


The first step in picking a bike is getting the right size. Where adult bikes are sized by the frame (measured from the center of the bottom bracket to the top of the seat tube), bikes for children are sized by their wheels: 12”, 16”, 20” and 24”. The bike should fit the child. The rider should be able to dismount and comfortably straddle the bike flat footedly. And then with a slight lean of the bike, get their bottom back onto the seat, put their foot on the pedal and, when the skill is there, ride away. They shouldn’t be riding scrunched up with their knees hitting the handlebars and they shouldn’t be stretched out and unable to turn the handlebars easily. At the slow speeds that kids start out riding at, steering by turning the handlebars is much more of an element of riding than at faster speeds where steering is done largely by leaning. If there are training wheels on the bike, all of the steering is done with the handlebars.


Approximate Age Child's Inseam Wheel diameter
( bike size )
2-4 years 14-17 inches
35-42 cm
12 inches
4-6 years 16-20 inches
40-50 cm
14 inches
5-8 years 18-22 inches
45-55 cm
16 inches
6-9 years 20-24 inches
50-60 cm
18 inches
7-10 years 22-25 inches
55-63 cm
20 inches
9+ years 24-28 inches
60-72 cm
24 inches


The size doesn't have any relationship to a real measure: It is certainly not the diameter of the rim. Generally the given size is closer to the tire/tyre diameter from tread-to-tread, but it is usually greater that this distance as well.



Some tips of choosing folding bike wheels size


Folding bikes typically come with 16, 20, 24, 26 and 27.5″ wheels. It’s best to select your wheel size based on how you plan to use your folding bike. The more regularly you’ll be using public transport, the better it is to go smaller and more compact. If you’re after long distance performance, you’ll want something with larger wheels and a wider gear range.


In general, it can be said that bikes with larger wheels (and therefore a larger fold) tend to perform better but are less suitable for public transport. On the other hand, the ultra-compact bikes are not as good for covering those longer distances but are super easy to transport.
