The UBesGoo 20-inch mountain bike is a kids' trail bike with a carbon steel frame, a 7-speed drivetrain and V-brakes. It is aimed at riders roughly 45 to 60 inches tall, so it fits many kids around 6 to 10 years old. The 7 speeds and knobby all-terrain tires put it ahead of single-speed 20-inch kids' bikes on hills and mixed surfaces. Against better-known kids' brands it is heavier and uses basic V-brakes rather than disc brakes, and owners of budget kids' bikes often report needing to adjust gears and brakes after assembly.
