Bell
This ASIN is 24 x 1.75-2.25 in. Match wheel diameter, frame clearance, and rim width.

Continental
Benchmark all-round race tire. 25mm is the most popular all-round size; 28-32mm is the best fit for endurance and rough roads.

Cubsala
Fits 20" BMX rims with 2.35-2.40" tire clearance - including CUBSALA Yaphet, Syzygy, and most stock 20" freestyle BMX bikes.

Maxxis
Most popular sizes: 29x2.5WT (modern enduro/trail front), 27.5x2.5WT (downhill), 27.5x2.3 (lighter trail). The wider WT (Wide Trail) versions are optimized for 30-35mm internal rims.

Mongoose
Replacement fat-bike tire - match the size to your existing rim and tire (20x4 or 26x4). Wire bead, so confirm rim width compatibility.

Royalbaby
Replacement outer tire for RoyalBaby and similar kids bikes 12-20" - confirm rim diameter and width before swapping.

Schwalbe
Most popular: 700x35C (37-622) for trekking, 700x32C / 28C for road commuting, 26x1.75 for older hybrids. Heavy (~890 g per 700x35) but virtually flat-less - accept the weight.

Schwinn
Drop-in 700×38c replacement for hybrid and commuter bikes. Confirm fender / chainstay clearance before fitting.

Bell
This ASIN is 700c x 32-45. Confirm frame and brake clearance before sizing up.

Continental
Built for winter training, wet weather, and bad roads. 28mm is the popular all-season choice; 25mm if you want a faster feel year-round.

Maxxis
Pair a 29x2.4WT or 29x2.5WT DHR II rear with a 29x2.5WT DHF front for the classic enduro setup. 27.5x2.4WT for World Cup downhill.

Schwalbe
The lighter, faster sibling of the Marathon Plus. 700x35-40C is the trekking sweet spot; 700x28-32C for commuting. Choose this over the Plus when you want livelier handling.

Five-year-olds are typically ready for a 16" wheel bike, though smaller children (under 107 cm) may still fit a 14" bike better. At this age, the majority of children have the coordination to ride without training wheels, and many can begin using hand brakes alongside or instead of a coaster brake. The correct fit means your child can sit on the saddle and touch the ground with the balls of their feet - flat-footed contact is no longer necessary. Look for bikes with a simple single-speed drivetrain; gears are unnecessary and add weight and complexity. A quality 16" bike typically weighs 6-8 kg; avoid anything over 9 kg, as heavier bikes are a serious barrier to enjoyment and skill progression.
Every bike tire carries two size numbers on the sidewall: the modern ETRTO (ISO 5775) format like 28-622 - width in millimetres, then bead-seat diameter - and an older Imperial label like 700×28c, 26×2.10, or 20×4.0. The first number stays the same regardless of width (700c = 622 mm, 26" MTB = 559 mm, 27.5" = 584 mm, 29"/700c = 622 mm). Width affects everything: a 700×25c rolls fast on smooth roads, 700×32-35c is the modern endurance and gravel default, 2.1-2.4" suits trail MTB, and fat-bike tires run 4.0-4.8" wide for sand and snow. Kids bikes follow wheel diameter - 12", 14", 16", 18", 20", and 24" - and replacement tires must match exactly. Always check your rim's max width and your frame/fork clearance (typically printed on the chainstay or fork) before going wider.
