A 20-inch kids mountain bike built around 3.0-inch wide knobby tires, a Hi-Ten steel frame and a rigid fork. It pairs a Shimano 7-speed drivetrain with dual mechanical disc brakes, so it handles dirt, gravel and grass better than a standard 20-inch kids bike. It suits riders roughly 46 to 61 inches tall, about ages 7 to 12, who want a rugged first mountain bike. Against typical kids MTBs with narrow tires and rim brakes, it trades some weight and rolling speed for grip and stopping power.

Rated 4.5 out of 5 from 69 ratings. Owners generally describe it as a solid, good-looking fat-tire bike for kids, with the wide tires and disc brakes standing out. The main complaints center on weight and on setup and adjustment out of the box.
The JOYSTAR Minifat is a 20" fat tire mountain bike for kids ages 7 to 12. It has 20" x 3.0" pneumatic tires with a wide contact patch, which give grip and stability on neighborhood paths and on sand, mud and snow.
The frame is Hi-Ten steel and the fork is rigid. Dual mechanical disc brakes handle stopping. A Shimano rear derailleur and a twist shifter give 7 speeds for climbing hills and varying pace.
A kickstand and reflectors are included. The bike arrives with the body 85% assembled.
