Overview
A kids/tween mountain bike sold across 20 to 26 inch wheel sizes with a 7 or 21-speed drivetrain depending on which size is chosen, built on a hydroformed aluminum frame with front and rear suspension and hydraulic disc brakes.
RoyalBaby ships the bike about 85 percent assembled, so the remaining setup is mostly attaching the handlebars, pedals and reflectors rather than a full build.
- Hydroformed superlight aluminum frame
- Shimano Deore 1x7 speed drivetrain (7 or 21-speed depending on wheel size)
- Front and rear suspension with hydraulic disc brakes
- Lifetime frame warranty
Who it's for
Sized for riders roughly 6 to 14 years old depending on the wheel size ordered, and works well as a bike a younger sibling can grow into or inherit. Best suited to parents who want a bike sturdy enough to hand down rather than the cheapest option available.
Pros and cons
- Aluminum frame with real Shimano derailleur and disc brakes
- Adjustable, well-padded seat suits a growing rider
- Ships about 85 percent assembled, so setup is quick
- Handlebars, pedals and reflectors still need attaching
- One buyer had a pedal work loose and strip crank threads
Performance notes
The front and rear suspension is meant to absorb bumps and roots on trails, and the 1x7 drivetrain trims shifting down to one lever so kids aren't juggling two shifters while learning. Hydraulic disc brakes provide single-finger stopping power that stays consistent in wet weather, per the listed specs.
