  • For 5-8 years old kid; 14” to 16” inches.
  • For 8-12 years old kid; 16” to 18” inches.

As concerning the posture difference among kids of the same age, here is the reconsideration of size preferences according to the height of the rider;

4—6 years 12 80—100

14+ years 18 130—160
14+ years 20 155—150+

Top-Tube Length

Being particular about the kid-bike companionship requires the settlement of size and length of different parts of the bike—wheel size, handlebars, and especially the top-tube length. This is the upper tube of the frame. The recommendations among are;

Height of the Kid (Rider) Top-Tube Length
For 2—3 ft.  11—13 inches.
For 2’8”—3’4”  12—15 inches.

For 5’—5’8”  20—20.5 inches.
For 5’6”—6’  20.5—21 inches.
For 6’+  21+ inches.

Chainring or Sprocket

The chainring is responsible for holding the chain between the crankset and the pedals—the real thing of concern is the teeth on the sprocket. The ratio gradually goes from 23 to 36 teeth or more, depending on the set of the gearing. Consider these facts for a better understanding of selection;

  • More will be the teeth of the sprocket—less power will be required to run the bike but the top speed will also be decreased as the teeth are increased in number.


The number of speeds depends on the gear set of the bike. Taking in account speeds, they are categorical as;

Single Speed

The single-speed bikes have only one chainring—thus, restricting the power and speed adjustability over one range only.

Multiple Speed

The number of chainrings is more than one and the teeth on these sprockets vary with an increase in diameter. Most of the advanced riders prefer multiple-speed bikes for better control over their power and velocity of the bike.

Gear Ratio

The gear ratio is the result of the number of teeth on the driven chainring divided by the number of teeth on the driver chainring. The most accumulated ratio is;

  • 25/9

The driven chainring is the gear that is attached by the saddles, in short, the gear that takes the power from the rider—the driver chainring is attached to the back wheel and they drive the bike.

Choosing the Balance Bikes?

Especially for toddlers that don’t have the practice to balance the cycle, this is where the balance bikes jump in. They don’t have the paddles installed in the structure, the kid can just push it with their legs, and attain enough speed so they can swift off for a while and experience the swift of ride’s decorum.

Does your kid need it?

  • If your kid is starting his/her experience with riding the bicycles and doesn’t know how to, therefore, rather than letting him/her fall in the park, again and again, it is better to let them learn without getting hurt.


The weight of BMX bikes plays a keen role in the selection—whether you are after cheap BMX bikes for kids or kids’ 18-inch bike, the weight matters. Certainly, beginner BMX bikes are needed to be light. Consider these;

  • The weight range (18 inches—wheel size) is; 8 to 12 kgs.
  • The weight range (24 inches—wheel size) is; 13—19 kgs.

Also, some facts over the weight liability.

  • Depending on the size; go for the lightest choice
  • Mainly, the multiple speed and steel body BMX bikes are heavy.


As for the toddlers, the suspension is not much of a deal, but growing with age and performance—the abuse of road causes the distortion in the ride, your kid won’t enjoy the bumps, thus the suspensions absorb all the harshness of the ride and delivers the comfortable the journey. There are mainly two types of suspension installed;

Spring Shocks

The steel springs are responsible for absorbing shocks.

  • Advantage: much economical when integrated into the bikes.
  • Con: catches rust and might lose their potential of sturdiness with time.

Hydraulic Shocks

They operate based on hydraulics—the air tension is created to push back the shocks.

  • Con: might get leaked, if hit enormously—can be pricier.

Training Wheel Leg

These are installed on the back wheel of the bike giving the stability of the bicycle standing itself—most of the models include them separately on demand, if your kid is on a balancing stage, make sure to add them up.
