The Best Kids Mountain Bikes Reviewed and Compared
Written by John Wren|

20- or 24-inch aluminum, stand-over first. RoyalBaby or High Timber. Shop assembly. Kryptonite Mini-7. A lid a shop sized.
Key takeaways
- Inseam, not age.
- Shop the brakes.
- Lock the frame.
- Not an adult 29er.
A kids mountain bike that still gets ridden is a wheel size that still matches inseam, brakes a shop set, and a lid a shop sized — not an adult 29er you lowered the seat on. The short answer: buy a RoyalBaby 20- or 24-inch if you want a mailbox aluminum, a Schwinn High Timber if you want a name a shop has seen, pay assembly, and lock the frame.
Short version. The bike page is the long fit. A beach cruiser if the other Saturday is already sand. Pair with a lock. Check live prices.
This page is knobby kids bikes. A road bike is drops. This is RoyalBaby, Schwinn High Timber, a Kryptonite.

Inseam first. A catalog age is a bruise.
Do: stand-over in the shoes they will ride. Don’t: a 24-inch hope on a kid who needed 20. Kids outside. A first race is a later door.
Shop assembly is not optional. Cables stretch. A garage “I figured it out” is a spongy brake at the bottom of a driveway.
RoyalBaby if you want a mailbox aluminum they will still grow on
The RoyalBaby 20/24-inch kids mountain bike is the live aluminum we named. Confirm wheel size on the listing. Check live prices.
The RoyalBaby Explorer 24-inch is the live alternate we named if 24 is already the inseam. Check live prices.
Do: a bell and reflectors you actually leave on. Don’t: a first ride after dark without a light. A handheld is a walk light, not a bike light. A shop lid is still the lid.
High Timber if you want a name a shop has seen
The Schwinn High Timber is the live kids-and-youth mountain bike we named. Confirm 20- versus 24-inch on the listing. Check live prices.
Do: twist shifters they can still reach. Don’t: a 21-speed maze on week one. A first road bike is a later teenager if they already live in drops.
A lock if the driveway is already a street
The Kryptonite Evolution Mini-7 is the live U-lock we named. Frame, not a wheel you leave. Check live prices.
Do: the same lock every time. Don’t: a cable you can grin through. The lock page.

Frequently asked questions
What is the best mountain bike for a kid?
A sized 20- or 24-inch aluminum a shop finished — RoyalBaby if you want a mailbox, Schwinn High Timber if you want a name a shop has seen.
20 or 24 inch?
Inseam decides. Stand-over in the shoes they will ride. A catalog age is a bruise.
Can they ride an adult bike?
No. A lowered 29er is a top tube they will meet. Buy a kids last.
Do I need a shop?
Yes. Mailbox bikes arrive unfinished. Pay someone to set the brakes.
What lock?
Kryptonite Evolution Mini-7 through the frame if the driveway is already a street.
Helmet?
A lid a shop sized for a kid. An adult road helmet is the wrong lid.
