Black XJD Kids' BMX Bicycle with Training Wheels

Product details

The XJD Kids' BMX Bicycle with Training Wheels is built for children roughly 3 to 10 years old (71–122 cm tall), and it's designed to make learning to ride safe and confidence-building — wide training wheels keep beginners steady, dual brakes deliver dependable stops, and the adjustable seat grows with your child across three wheel sizes (12", 14", 16").

What age and height is it for?

This black kids' BMX bike covers a wide age range — 3 through 10 years — with a rider height span of 71–122 cm. The right size comes down to wheel diameter: smaller riders start on the 12-inch wheels, while taller kids in the upper height range are better matched to the 16-inch option. Because the seat and handlebars adjust upward, the bike stays comfortable as your child grows. As always with kids' bikes, height is a better guide than age — confirm your child can stand over the frame and reach the pedals and handlebars comfortably before riding.

Key features

• Three wheel sizes: 12, 14 or 16 inch wheels for kids aged 3–10 (71–122 cm), with an adjustable seat height so the bike grows with your child.
• Dual braking: front caliper brake plus rear coaster brake for quick, dependable stops.
• Training wheels: wide, sturdy training wheels hold the bike steady and prevent tumbles while confidence builds.
• Durable frame: carbon steel BMX frame that's sturdy yet easy for kids to handle, with rear suspension.
• Comfort details: shock-absorbing saddle and soft grips fight fatigue on longer rides; thick, non-slip tires grip well across different surfaces.
• Single speed drivetrain: simple chain drive — nothing to shift, ideal for beginners.
• Safety bell included.
• Adjustable handlebars and seat.

Safety details

Beyond the training wheels and dual brakes, an enclosed chain guard keeps small fingers away from the chain. Before every ride — especially after assembly or any adjustment — an adult should check the brakes, tires, steering, saddle position and all fasteners. Pair every ride with age-appropriate protective gear (a helmet is a must) and active adult supervision.

Assembly & what's in the box

Assembly is rated easy. The bike ships 85% pre-assembled, so you only need to install the training wheels, pedals, seat and handlebars using the included tools and instructions — no bike shop visit necessary. The package includes the kids' bike with bell; note that this listing is for the black colorway (the same design is offered in Blue/Red/Pink elsewhere).

Every part is built to last and wipes clean easily, which matters when the bike lives in a garage or gets left in the yard.

Bottom line

If your child is between 71–122 cm (roughly ages 3–10) and needs a first bike or a balance-building upgrade, this is a solid pick — just choose the wheel size that matches their current height, not the age on the cake. If your rider is already taller than about 122 cm, move up to a larger kids' bike instead.
