350 mm
Lowest saddle position
At this height both of the child's feet rest on the ground while seated. On a balance bike the child's own feet are both the engine and the brake.
Size guide
One measurement is enough: the child's inseam.
01 — Measuring
Height and age mislead; two children of the same age can have legs 5 cm apart. On a balance bike the only measurement that decides fit is the distance from the child's crotch to the floor. You can measure it at home in two minutes.
02 — Calculate
The calculation follows the common method of setting the saddle 1-2 cm below the inseam. The saddle range used here is a pre-production design target and will be confirmed in series production; this page will be updated once it is final.
03 — The figures
350 mm
At this height both of the child's feet rest on the ground while seated. On a balance bike the child's own feet are both the engine and the brake.
430 mm
The saddle rises as the child grows. This figure is not final yet; see the note below.
1-2 cm
The saddle is always set slightly below the inseam. Set level with it, the child ends up on tiptoe and loses confidence.
350 mm is the design target in the production file. 430 mm is provisional: it is derived from the adjustment range common in the 12-inch class and has not been verified. Maximum rider weight and handlebar adjustment are not listed because the data is not ready.
