What age or height is the Relic 24 for?

It is a 24-inch-wheel kids' bike, typically suited to children around 8 to 12 or roughly 4'2" to 4'9". Check the child's inseam against the standover height before buying.

Does it come with gears?

Yes. It has a multi-gear drivetrain with a rear derailleur, so it climbs better than a single-speed kids' bike.

Is it good for real mountain trails?

It handles dirt paths, gravel and light trails. The suspension fork is basic, so it is not built for jumps or aggressive downhill riding.

How much assembly does it need?

Expect to fit the front wheel, handlebar, seat and pedals, and to check brake and derailleur adjustment before the first ride.

How does it compare with a department-store kids' bike?

It uses a proper mountain-bike frame, suspension fork and gears rather than a heavy steel frame and coaster brake, so it rides better off-road but costs more and needs more upkeep.
