Glerc Bikes | Kids Bikes 12"–26" for Toddlers to Adults – GLERC BIKES

Choose according to the rider’s height, inseam, and bike-handling ability rather than age alone. The 20-inch Mars fits riders approximately 47–59 inches tall, while the 24-inch version fits riders around 51–65 inches tall. Riders within the overlapping range should compare the fit with other 20 inch bike and 24 inch bike options before ordering.

Yes, Mars can be a good first kids mountain bike for a rider who already knows how to balance and is ready to learn gears and hand-operated brakes. Training wheels are not listed as included, so it may not suit a child who still depends on them. New riders should practice shifting, turning, and braking on flat, traffic-free ground before using trails.

Yes. Both sizes use 2.8-inch-wide knobby tires designed to provide additional grip and stability on pavement, packed dirt, gravel, grass, and light trails. Riders interested in comparing other wide-tire designs can explore Glerc’s fat tire bike collection.

No. Mars uses a rigid fork rather than front or full suspension. Its wide tires can provide some cushioning over smaller surface irregularities, but they do not replace a suspension fork; families who need suspension for rougher trails should compare the specifications of other mountain bikes.

Mars has a Shimano 6-speed drivetrain with a trigger shifter. The lower gears help reduce pedaling effort on inclines, while the higher gears suit flatter paths and faster riding. Riders should shift while pedaling smoothly and reduce pressure on the pedals during each gear change.

Yes. Mars is equipped with hand-operated disc brakes and internally routed brake cables. Before every ride, check that the brakes engage correctly, the levers are within comfortable reach, and the bike stops without unusual rubbing or noise. A qualified bike mechanic should inspect any braking problem that cannot be corrected using the product instructions.

Mars is suitable for neighborhood streets, park paths, gravel, packed dirt, grass, and beginner-friendly trails. Its rigid fork and beginner-oriented design are not intended for large jumps, aggressive downhill riding, or highly technical terrain. The rider should also wear a properly fitted bike helmet for kids and ride with appropriate adult supervision.

Mars arrives approximately 85% pre-assembled and includes an installation kit. The package also lists a bell, kickstand, and DIY stickers for both the 20- and 24-inch versions. Before the first ride, an adult should carefully check the quick-release front wheel, handlebars, pedals, saddle, tires, brakes, and gear shifting.
