Kids Bike Buying Guide

1. Size metaphysics: Don't be fooled by "wait until you grow up"

Last time, the neighbor's child fell while riding a 20-inch bike, and I realized that the frame height is more important than the wheel diameter! Remember this formula: child's height × 0.65 = optimal seat height. For example, my daughter's height is 55cm, so I choose a model with a seat height of about 35cm. Don't believe the nonsense of "buy big instead of small" - I have seen children who can't reach the brakes but still ride hard, just like stepping on a sewing machine.

2. Hidden test points of safety configuration

Brake system: V brakes are like a small train "squeaking" but powerful, disc brakes are quiet but difficult to maintain. It is recommended to choose a holding brake for children under 5 years old, and the finger strength is just enough.

Training wheels: Choose ones that can be quickly removed! Don't wait until the child can ride and still can't remove them. Those who race tricycles in the community are all like this.

Handlebar steering limiter: This plastic piece can prevent the handlebar from turning 180 degrees, avoiding "turning over and falling headfirst", but many cheap cars do not have this design.

3. Material traps revealed

Aluminum alloy frame: light and rust-free, but feels like ice in winter. Remember to install antifreeze grips.

Steel frame bike: stable as an old dog, but lifting it is like carrying a gas tank. Suitable for living in an elevator apartment.

Carbon fiber: unless you want to train a Tour de France champion, it is a waste of money - children grow up faster than cars depreciate.

4. Those crazy details

Tire pattern: fine-grained road tires slip on the cobblestone roads in the community, and coarse-grained mountain tires are heavy and noisy

Bell position: Don't buy one placed in the middle of the handlebars. The child may lose balance when reaching for the bell

Light installation: Most children's bicycles have reserved holes that are only compatible with AA batteries, and lithium batteries need to be punched

5. Secrets of used cars

Check these 5 places before buying:

Is the crank bearing rusty (there is a rustling sound when turning)

Is the brake line hard (slow rebound when squeezed to the bottom)

Is there any crack in the seat sliding track

Tire production date (rubber will age after more than 5 years)

Previous owner's height (the handlebar height is not suitable and the assembly needs to be replaced)

6. Accessories blacklist

Luminous wheel hub: battery box leakage corrodes the rims

Cartoon bell: excessive decibels scare passers-by

Multi-function tool kit: the child can't use it at all and it adds weight

Remember to take the children to the physical store to try the car, some children just don't like a certain handlebar shape. My son refused to ride the princess model, and I finally found out that he hated the bell shape.
