Is there an 18 inch bike?
Yes, there are 18 inch bikes available on the market.
These bikes fit kids who are between 4 years and 5 years old.
However, there are not many brands or models that are available compared to the other wheeled sizes.
The 18” bike tries to close the gap between a 16 inch bike and a 20 inch bike for kids who are tall or short for these sizes.
What does an 18 inch bike mean?
An 18 inch bike refers to the size of the bike in terms of the measurement of the diameter of the wheels.
So, if the diameter of the wheel measures 18 inches, the bike then is referred to as an 18 inch bike.
Kid’s bikes are referred to in terms of wheel size, unlike adult bikes which are measured in terms of frame size.
It’s an effort to close the gap between the 16 and 20 inch sizes for kids who are tall or short for these sizes.
Who can ride an 18 inch bike?
Typically 18 inch bikes cater to kids who are between 42 to 52 inches tall.
If the kid is 4 years to 5 years old but is taller than an average 4 to 5-year-old, then an 18 inch bike is a good option.
Likewise, if the kid is 6 to 7 years old and is short for her age, an 18 inch bike can be considered.
18 inch refers to the size of wheels as this is how the kids’ bikes are measured, unlike adult bikes that are measured in terms of frame size.
So if the wheel size measures 18 inches in diameter, the bike is an 18” bike.
However, the frame size will defer irrespective of the size of the wheels.
Different manufacturers might have different frame sizes for the same wheel size.
Instead of age, a better way to gauge fit is to go with the height of the kid and how comfortable the kid is with the bike.
Is an 18-inch bike for a 6 year old?
If the child is shorter than an average 6-year-old then an 18 inch bike would be a good fit.
The way to measure fit is to first measure the inseam height of the child.
Have the kid stand against a wall with no shoes on and measure the length from the floor to the crotch. This is the inseam length.
If the kid is able to stand over the bike comfortably and if the space between the saddle and the handlebars don’t feel cramped while riding, then the bike would be a good fit.
How tall should you be for an 18 inch bike?
An 18 inch bike fits kids who are aged 4 to 5 years.
If the kid is taller than the average 4 to 5-year-old, then, instead of a 16in you can opt for an 18in bike.
Conversely, if the kid is short for a 20 inch bike, then an 18 inch would be a good option.
What size is an 18 inch mountain bike?
An 18 inch mountain bike refers to the diameter of the wheels.
Most of the 18 inch mountain bikes are made for kids as they would be small for an adult.
Even though the size of the wheels remains the same with all the manufacturers, the size of the frame can vary between brands.
Can an adult ride an 18 inch kids’ bike?
18 inch bikes are for kids that measure between 42 to 52 inches in height.
Adults who are short can consider 18in bikes too.
We would however recommend you to check a 20 or 24 inch bike if you are an adult and see whether that fits you before considering an 18” bike.
Are there 18 inch bikes with training wheels?
Yes, certain bike brands do have 18 inch bikes with training wheels in their lineup.
Joey and Schwinn are two brands that have 18” bikes with training wheels.
You can detach the training wheels once the kid has learned to balance and pedal without any support.
Are there different 18 inch bikes for girls and boys?
No, all the bikes fit girls and boys equally well.
The only difference would be in terms of color which might appease boys and girls differently.
Just choose any model that your child is comfortable with.
Some bikes do have top tubes that are very low for girls to hop in and out easily.
However, all the 18 inch bikes that are available in the market do have sloping top tubes that fit both boys and girls equally well.
Do 18 inch bikes have gears?
18 inch bikes are not a staple category in most of the bike brands’ size lineup.
Only a few brands do have an 18 inch bike segment.
Because of this, all the bikes in this category come with no gears.
However, we believe that in the future this could change as more manufacturers start bringing out 18” models.
Where to buy 18 inch bike?
18 inch bikes are available in online retail stores, and local bike stores or can even be ordered directly from the manufacturer’s website.
Since 18” bikes are rare compared to other size categories, you may not see an 18in bike in your local bike store though.
Do 18 inch bikes come with coaster brakes?
Yes, some brands come with coaster brakes but we recommend trying your kid on a bike with hand brakes.
Coaster brakes can be confusing for the child and can even result in losing balance and falling down.
The other aspect of coaster brakes is that the transition to handbrakes in the future can be challenging as the child would have gotten used to it.
