Best Bike for 4 Year Old Kids 2020- (16 inch Bikes Review)


Searching for the best bike for 4 year old kids? We got you 10 bikes that are worth every penny.

Deciding on a  kid’s bike can be quite confusing. The price, size of the bike and braking system are all deciding factors.

Bike size is mainly associated with wheel size. We reviewed only 16-in bikes as these will be perfect for kids at this age and also grow with them till 7 or 8. You don’t want to throw away the bike after a year of use. Anything less than 16-in will be too small and over that will be too big to ride.

A handbrake and foot brake (coaster brake) combo is the best option you have. However, bikes with just the coaster brake will also be good enough for braking.

Keeping price and all other factors in mind, here’s our top picks!

5 Best Bikes For 4 Year Old Kids 2020

1.RoyalBaby Kids Bike

When it comes to overall value, RoyalBaby is just unbeatable. It’s well-built, stable and has one of the best braking systems for kids at 4 to learn biking fast. With 7 exciting color options, it’s easier to find a bike that your kid will love.

What makes it truly safe is the combination of a handle brake and a coaster brake. So, your kid can control both the front and rear wheels with ease. The 2.4-in wide wheels offer ample stability along with training wheels to eliminate falls and accidents.

The chain is enclosed within a frame to protect against legs sliding into the chain or any part of the trouser getting stuck. Despite the enclosure, it’s easier to adjust the chain tension as the rear axle sits in a groove.

Most of the parts come pre-assembled and you should be able to get it together in 20 minutes. You just need to adjust the handle brake a bit to stop it rubbing against the tire. Sometimes the training wheels might become loose and a simple thread locker or plumber’s tape can solve this issue.


  • All adjustable handlebar and seat setting.
  • Handle brake and coaster brake combo makes riding safe.
  • Easy to grab handle on the seat for training efficiency
  • Enclosed chain is safe yet easy to adjust.


  • Training wheels might need adjustment sometimes.



2.Dynacraft Dirt Bike

The first thing you will notice about this bike is that it resembles a dirt bike. The design and color looks cool and especially the decal makes it more appealing to sporty kids.

At 24 lbs, it’s the most lightweight bike out there but not certainly not the heaviest. The training wheels will help your kid to get a hold of the bike. The good thing is kids can use it until 8 years of age.

This bike comes with coaster brakes only. While having just coaster brakes calls for a bit of a skid sometimes, this also makes it one of the best dirt bikes for a 4 year old. For starters, handling this sort of brake is a lot more practical.

The factory assembling is super tight and has no wobbling parts. But you will need to loosen the wheel bearings and re-grease them to make them more swift and functional.

Everything about this bike is loveable. However, the instructions are just awful. If you know a thing or two about bikes as most of us do, you would be able to get it together with a bit of hustling. For parents with zero DIY bike skills, get ideas on youtube or get a mechanic.


  • Training wheels are removable and also adjustable.
  • Great for dirt biking.
  • Vibrant and exciting color and design.


  • Instructions are limited and needs some digging to get it together.

It’s a great beginner bike that comes with a coaster brake to make it easy to stop. The training wheels offer additional support that can make your child learn biking faster than ever.

We loved the cruise style design and it really makes riding a hell lot more comfortable than traditional bikes. This helps to keep a low center of gravity and minimize falls.

You can adjust the handlebar to be either front or back. Additionally, the seat can also be adjusted and has a low setting of 21.5-in, which is perfect for kids at this age.

The whole thing comes 85% assembled. That translates to 20 minutes to put this together. It would have been a lot better if there was some kind of grip on the pedals as the foot can slip sometimes. But that won’t keep your child from riding this bike!


  • Cruiser style design makes riding comfortable.
  • Seat height and handlebar position is adjustable.
  • Fast and easy assembling process.
  • Enclosed chain for safety and protection against dirt and rust.

Most of the functionalities of this bike is similar to the RoyalBaby bike we reviewed earlier. The front caliper brake and the coaster brake together makes it really safe for toddlers.

The tires are wide enough to maintain stability along with training wheels. Whether your kid is riding on the pavement, grass or mud, this thing will hold up quite well and last until he outgrows it.

You can adjust the height of both the seat and the handlebar. Kids at 4 can have a lot of differences. And this option helps to find the right setting for any kid. On the plus side, the pedal is non-slip and for girls that’s what you need.

Most of the bike parts come assembled and the instructions are clear and easy to understand. We would have appreciated more if the training wheels had some sort of adjustment setting to lift them off further when the child grows in size.


  • Adorable and all girly design for little ladies.
  • Adjustable handlebar and seat setting.
  • Front caliper brake and coaster brake combo.
  • Relatively more lightweight than other bikes.

This bike scores quite high in terms of safety and lightweight feature. The front hand brake and the rear coaster brake together helps to stop efficiently without skidding. The weight is acceptable compared to the price you pay.

Kids will love the wider pedals as it will help them to ride comfortably with less effort. Even the handlebar has raised edges to keep the hands in place.

The doll carrier behind the seat is a deal breaker. However to use it effectively the seat must be set at the highest setting or you can bend the carrier to adjust to the lower setting of the seat.

It’s almost completely pre-assembled. You just need to get the wheels, handlebar and pedals in place. It’s ready to ride with no extra adjustments!
