12 dirt-style bikes, seat heights from 830mm to 940mm (10 LAMS-approved). Sorted by seat height — tap any bike to see your riding posture and ground reach for your body size.
Seat height & wheelbase come straight from the manufacturer’s published specs, verified across the maker’s site, media reviews and spec databases.
Handlebar & footpeg positions aren’t published by any manufacturer. Where a true side-profile photo exists, we mark five reference points on it (front & rear axle, seat, grip, peg) and convert pixels to millimetres using the known wheelbase as the scale. Where it doesn’t, we research the grip and peg heights and estimate the horizontal reach from class-typical geometry.
Every result is cross-checked against how reviewers describe the bike’s posture (upright / sporty / committed), and each bike page carries a data-confidence badge so you can see how solid its numbers are.
The drawing is a clean schematic — one shared template per bike type (naked, sport, cruiser, adventure, touring, dirt), anchored to each bike’s real seat, grip and peg coordinates — so you compare riding positions, not paint jobs.
Your figure is a stick model built from your height and inseam using standard body-proportion ratios, then posed by inverse kinematics — hips on the seat, hands on the bars, feet on the pegs — with the same posture solver for every bike.
Bottom line: seat height & wheelbase are hard data; handlebar/footpeg geometry and ground reach are calibrated estimates (see each bike’s data-confidence badge). Always sit on the real bike before you buy.
