You can determine the correct bike size for your 4-year-old by considering their height, inseam, or both. Let’s look at the relevant size charts.
Kids Bike Size Chart by Height
Below is a size chart for different heights. Use it to determine what wheel size suits your child, depending on age and height.
|Child’s Age||Child’s Height||Wheel Size|
|2 – 3 years||2’10” – 3’4″ (85 – 100 cm)||12″|
|3 – 4 years||3’1″ – 3’7″ (95 – 110 cm)||14″|
|4 – 5 years||3’7″ – 4’10” (110 – 120 cm)||16″|
|5 – 8 years||4’0″ – 4’5″ (120 – 135 cm)||20″|
|8 – 11 years||4’5″ – 4’9″ (135 – 145 cm)||24″|
From the table below, 4-year-olds who are 3’1″– 3’7″ tall (or 95 – 110 cm) can ride a 14-inch kids bike, while those who are 3’7”-4’0″ tall (or 110 – 120 cm) should get a 10-inch bike. Remember, we are talking about the wheel size when inferring to 14 inches and 16 inches.
Kids Bike Size Chart by Inseam
Since it’s essential that your 4-year-old can sit upright and touch the feet on the pedals or ground, you should consider their inseam length. Here’s a sizing chart to help you with that.
|Child’s Age||Inseam Length||Wheel Size|
|2 – 3 years||14 – 17″ (35 – 42 cm)||12″|
|3 – 4 years||16 – 20″ (40 – 54 cm)||14″|
|4 – 5 years||18 – 22″ (45 – 55 cm)||16″|
|5 – 8 years||22 – 25″ (55 – 63 cm)||20″|
|8 – 11 years||24 – 28″ 60 – 72 cm)||24″|
The table shows that 4-year-olds with an inseam of 16 – 20″ can ride 14-inch bikes, while those with an inseam of 18 – 22 can ride 16-inch bikes.
How to Measure Bike Size for Kid?
Now that you know your 4-year-old needs a 14-inch or 16-inch bike, how do you choose between the two? Well, you’ve to measure your kid’s height or inseam if you don’t know or are not planning to buy the bike in a physical shop where the kid can try it.
Let’s talk about how to do it.
How to Measure Your Kid’s Inseam Length?
You need a tape measure and textbook (or any hardcover book) to carry out this little procedure, and here’s how to do it:
- Ask your child to stand upright against a wall while the legs are shoulder-width apart
- Then put the book between the legs and push it high but don’t hurt the kid
- Then measure the distance from the book’s top to the ground to determine whether the kid needs a 12- or 14-inch bike.
How to Measure Your Child’s Height?
Your child should take the same position as above (stand straight against the wall and legs shoulder length apart). You’ll then need to place a textbook on the head and touch the wall, not between the legs.
After that, measure the distance from the book’s bottom to the ground to determine the child’s height.
Bike Types for a 4 Year Old
You can get your 4-year-old a balance bike or a pedal bike with training wheels. Let’s see what they are all about.
1. Balance Bike for a 4 Year Old
A balance bike, sometimes known as a pedaless bike, is just what the name suggests. This bike’s purpose is to enable your child to learn to balance. And when they do, they can easily transition to a regular pedal kids’ bike.
A balance bike builds biking confidence, and that’s what the Joystar 14/16 Inch Balance Bike (check the Amazon link above) promises. This balance bike is available in 14- and 16-inch options to suit 4-year-olds with different heights; your kid can grow with it for up to 8 years.
It’s lightweight, fun to ride by kids, and safe, owing to its clipper brakes.
Its pneumatic tires easily roll over bumpy surfaces, allowing your child to ride outdoors. Plus, there’s a u shaped footrest for the young rider to rest their feet as they cost.
2. Pedal Bike with Training Wheels for 4 Year Old Boy
Once your 4-year-old learns to balance, you can get them a pedal bike. You can skip the balance bike and get a pedal bike with training wheels. The training wheels, sometimes known as stabilizers, will boost the bike’s balance and enable the little one to pedal independently.
And once they are confident pedaling and balancing, you can detach the stabilizers to allow the child to ride without them.
One bike for a 4-year-old boy that promises that is the Schwinn Krate Evo Classic Kids Bike (Check Amazon link above). Walk your 4-year-old down memory lane with this classic kids’ bike by Schwinn.
It has a bossy stingray-inspired appeal that rarely goes unnoticed and is available in multiple colors. The Schwinn Krate Evo Classic is best for kids aged 3 – 5 years and comes with removable stabilizers.
So, your child can ride it for at least a year. The bike features a suspension fork for smoothening the bumps and is fun to ride.
Its alternative pick is the RoyalBaby Kids Bike Cubetube (Check the Amazon link above). A 4-year-old can ride a 12-inch, 14-inch, or 16-inch when it comes to this kids’ bike. It all depends on the young rider’s height.
The bike looks pretty, safe, and friendly, even for those kids who’ve never ridden a bike.
How to Help Your 4-Year-Old to Ride a Bike?
Here are the tips to use:
- Start with a balance bike if the child has never ridden a bike before
