These are the Best 20″ Boys Bikes For 5 to 9 Year-olds

Children grow up quickly, which means they may need a new bike every 2 or 3 years. Just like with adults, it’s important to fit the right bike size for kids so they avoid strain or injury and get the most enjoyment out of bike riding. The correct 20-inch bike age is usually somewhere between 5 to 9 years old, and once children reach 5 years of age, they have usually learned to pedal and balance on their own. At this point, you can upgrade from a 16-inch training bike to their first real 20-inch bike.

Why To Get A Mountain Bike For Boys?

Boys tend to be rough with their toys and they like getting dirty, so a mountain bike is a perfect answer. Boy’s mountain bikes are built tough to handle abuse and have thicker tires for better shock absorption, so they’ll want to ride more often. Statistics show that kids who ride bikes have a far less chance of developing obesity in adulthood.

BMX vs Urban vs Mountain Bike

BMX bikes are designed specifically for use in parks to do tricks and jump on ramps and half-pipes. Although they can be ridden elsewhere on streets and in nature, they usually aren’t as comfortable as mountain bikes over long distances. BMX bikes usually only have one gear so it can be difficult to ride up long hills with them.

You won’t be able to do the same tricks and jumps on mountain bikes, but you can tackle varied terrain, explore the mountains and charge downhill with front suspension.

Urban bikes have lighter frames and thinner, smoother tires than mountain bikes, so they’re easier to ride on pavement. However, they are weaker and rarely have any suspension, so they aren’t as fun for off-road riding.


 

Quick Round-Up:

Best 20″ Mountain bikes:

  • Best Full-Suspension MTB: Norco – Fluid
  • Best Equipped Hardtail MTB: Prevelo – Zulu Three / woom
  • Most Popular: Cannondale Trail 4
  • Best Value: Co-op Cycles – REV

Editor’s Recommendation 🏆

For best quality, you can’t beat the Norco Fluid. It has the best selection of parts and will provide the most fun ride. However, it is the most expensive.

For the best value for money, I’d choose either the woom – OFFAIR or the Prevelo Zulu Three. Both these bikes, while relatively expensive, provide a host of excellent components that will last a long time and provide top performance.

BEST 20″ BOYS MOUNTAIN BIKES

 


 

Prevelo – Zulu Three (+Three Heir)

Best in overall parts & performance

boys 20 inch bike

MSRP: $949 – $1,249
Prevelo

This high-quality 20-inch bike from Prevelo Bikes is quite pricey for a kids’ hardtail and best suited to boys who are serious about their riding. The 10-speed Shimano Deore drivetrain has Rapidfire shifters and features a Shadow rear derailleur with an 11-36T cassette and a 30T alloy sprocket on an HEIR crank. Sadly, the groupset doesn’t expand to the brakes, featuring only Tektro rather than Shimano hydraulic discs. 

Up front, you get an impressive SR Suntour XMC air-sprung fork with 80mm of travel, decent enough for some big jumps or serious downhill charging. The wheelset is fairly basic, featuring standard alloy rims and Kenda Small Block 20×2.1″ tires.

If you want to upgrade your Zulu Three you can go for the slightly more price Zulu Three HEIR at $1,249. This benefits from some significant upgrades, including an HEIR 20 80mm carbon/alloy fork with adjustable rebound, Shimano SLX drivetrain with HG500 cassette, and VEE Crown Gem tires on Stan’s Crest tubeless-ready rims. It’s basically a professional-level MTB for small people!

Optional extras include a dropper post, custom color grips, bicycle bell, personalization, rechargeable USB lights, and an official Prevelo team jersey.

Co-op Cycles – REV 20″

Best Value!

MSRP: $339
REI Co-op

The Co-op REV 20 is a mid-range REI kids bike that would make a great introductory MTB or an upgrade from a 16″. It’s light, simple, and affordable without coming across as cheap and has everything a kid needs in his first MTB.

The 6061 aluminum frame hosts a basic 6-speed Shimano Tourney gearset with Logan mechanical disc brakes and simple Revo twist shifters. There’s no suspension so clearly, this is not intended for downhill or park riding but will provide hours of entertainment riding around local parks and trails.

Cannondale – Trail 20″

MSRP: $450
REI Co-op

This 20″ mountain bike from Cannondale is an excellent introductory MTB from a well-known and trusted brand. It features a quality C2 alloy frame and Suntour suspension fork with 40mm of travel. This is great for kids wanting to hit ough trails and experiment with some basic downhill riding.

  • Kickstand
  • 20 x 1.95″
  • V-Brakes

The drivetrain is fairly simple – a 7-speed Shimano Tourney with a single Revo twist-shifter which is more than enough for a kids’ bike. However, the use of alloy V-brakes rather than disc brakes is a bit disappointing, especially on a mountain bike.

woom – OFF AIR 4

MSRP: $869

  • 20 x 2.25″ tires

Keeping up with the quality you also get fat 2.25″ Schwalbe Rocket Ron tires on superlight Woom rims, paired with Promax hydraulic disc brakes. Sure, it’s not the cheapest but even at $869, this bike offers excellent value for money.

MSRP: $450
Trekbikes (Available in-store only)

The Roscoe is a 20″ Trek bike with 2.8″ mid-fat tires that are wide but not too heavy, making it ideal for exploring some wild terrain without sacrificing pedal power. Fat tire bikes can be notoriously heavy to pedal so this makes for a nice middle-ground introduction to bigger tires for smaller riders. 

It has a lightweight Alpha Aluminum frame with a rigid fork and Shimano Tourney 8-speed drivetrain. The Tektro mechanical disc brakes aren’t the best but they get the job done, and the wheelset includes basic alloy rims with Chen-Shin tires.

Scott – Scale 20

This kids 20-inch mountain bike from legendary manufacturer Scott would make an excellent upgrade for a budding rider. The alloy frame includes an SR Suntour fork with 40mm of travel and a 7-speed Shimano drivetrain.

  • 20 x 2″ tires

We would’ve liked to see disc brakes rather than alloy V-brakes which are quickly becoming redundant but they do the job. The Kenda 2.2″ Booster tires are decent quality and overall it’s a nice bike although it lacks any outstanding features.
