Strider is a balance-bike brand from Rapid City, South Dakota, started in 2007 by Ryan McFarland after he stripped a pedal bike down so his son could learn to balance first. The range runs from a 2-in-1 rocking bike for babies up to the 20x Sport, which Strider lists for late learners and riders with special needs. Strider sizes by age and inseam rather than height, so this page converts the published inseam range into a height range.
Official website →Height ranges compared
Used sizes share one height scale, so overlapping and identical ranges are visible before you read a single table.
Height ranges on this page, from 42 to 195 cm. Strider Baby Balance Bike: 48–65 cm. Strider 2-in-1 Rocking Bike: 57–100 cm. Strider 12 Comp: 67–89 cm. Strider 12 Sport: 67–100 cm. Strider 12 Pro: 67–100 cm. Strider 14x: 87–126 cm. Strider 20x Sport: 124–189 cm.

Height filters the chart. Cycling inseam decides which overlapping size to keep. The method is the same for every brand.
Height
Take shoes off and stand tall, looking straight ahead. A helper should rest a flat object on the crown of your head, then run a tape from the floor to the underside of that object. Save the number in inches and centimeters — charts use both.
Inseam
Stand tall and barefoot with feet slightly apart. Ask a helper to measure vertically from your crotch to the floor. Keep your legs straight and feet flat.

Use your height on the Kids chart on this page. On the kids table, 57-65 cm sits in both Strider Baby Balance Bike and Strider 2-in-1 Rocking Bike. Cycling inseam and standover pick the side. Then check stack and reach for the exact Strider model.
Strider kids sizes on this page are wheel diameters paired with height and inseam (Strider Baby Balance Bike and Strider 2-in-1 Rocking Bike), not adult S/M/L or road centimeters. The child should stand over the bike and reach the brake levers before you buy.
The Kids chart on this page includes Strider Baby Balance Bike, Strider 2-in-1 Rocking Bike, Strider 12 Comp (48-189 cm on the kids table). Verify the current Strider model chart on the official site before purchase.
