The overall score is owner satisfaction weighted by how many reviews back it, so a high rating from few reviews counts for less.

Context, not marks against it, and our read of the data, not a lab test.
Overview
The RoyalBaby RB16B-6PH uses a carbon steel frame in a BMX-inspired design with 16-inch alloy steel wheels. What stands out from the spec sheet is the brake setup: caliper brakes in front and drum brakes in the rear. Drum brakes are more weather-resistant than standard caliper brakes and do not require the same regular pad adjustment, making them a practical choice for a kids bike that will see all conditions.
The frame is rigid with no suspension, which is typical for a BMX-style build at this size. The single-speed drivetrain is appropriate for the 4-to-7-year age range listed. The bike is human-powered with no mention of training wheels included, suggesting it is aimed at kids who can already balance or are close to it.
The review base is notably strong for a kids bike. 2,400 ratings averaging 4.5 stars is a high confidence signal, and the 2021 model year suggests it has had real-world use across multiple riding seasons. At $159.99, it is priced at a slight premium over basic 16-inch alternatives but justified by the braking setup and brand reputation.

Frequently asked questions
What is the advantage of a drum brake over a coaster or caliper brake?
Drum brakes are enclosed inside the wheel hub, which protects the braking mechanism from mud, water, and grit. They also require less frequent adjustment than caliper brakes and provide consistent stopping force in wet conditions. For a kids bike used outside year-round, that durability is worth having.
Is this bike appropriate for a 4-year-old who just learned to ride?
The listed age range is 4 to 7 years. A 4-year-old who can balance and pedal independently should be able to manage a 16-inch bike. If your child is on the smaller side for their age, check their inseam against the standover height before purchasing.
Does the RoyalBaby RB16B-6PH come assembled?
Like most bikes shipped via courier, it arrives partially assembled. You will typically need to attach the handlebars, front wheel, pedals, and seat. Assembly takes most adults 20 to 40 minutes with basic hand tools.
