Is the Bicycle 3D model free for commercial use?

Yes. It is free under the 1DesignTool 3D library license: use it in personal and commercial work — games, apps, websites, renders, ads and client projects — and modify it as you like, with no credit required. What you can't do is re-sell or re-distribute the file on its own or inside a model pack.

What file format is it, and how big is it?

A single binary glTF 2.0 file (.glb), 299 KB: 2,840 triangles, 7,508 vertices and 26 materials, modelled in metres at 64 cm × 1.2 m × 1.9 m.

Yes — the GLB carries a baked animation (4.0 s), ready to play with any glTF animation mixer.

Which engines and tools can open it?

Anything that reads glTF 2.0. three.js, React Three Fiber, Babylon.js, Godot 4 and Blender import the GLB directly; Unity and Unreal Engine load it through their glTF importers. The snippets above show the exact code for three.js, React Three Fiber, Godot and Blender.

How was the Bicycle 3D model made?

Claude Code (Claude Opus 5.5) generated it inside 1DesignTool's 3D template from a written brief, then the design kit's checks verified the geometry and the GLB before it was published. You can make your own the same way with 1DesignTool.

Bicycle

A low-poly city bicycle with a lawn-green diamond frame, a brown wicker front basket, a rear rack, full mudguards, a chain guard and a kickstand. In a seamless 4-second loop the wheels roll, the pedals turn and the handlebar sways a little.

How it was made

The brief given to 1DesignTool's “3D object” template:

Bicycle for the Suburban Street kit. Design it as one clear asset at believable real-world scale for that setting (state the size in metres in meta.notes), with its main parts modelled and named, readable at thumbnail size and from every orbit angle. It moves: author a seamless baked loop (2–12 s) with every pivot exactly at its hinge, axle or swivel, and keep the base still. This is one part of the Suburban Street kit (Low-poly style, flat-lowpoly direction): Quiet family homes on a curved road. Use ONLY the kit palette, by name: pastel siding #c4c4c4, lawn green #3a883a, asphalt #3b3e45, white trim #f4f1ec, pastel siding dark #9e9e9e, lawn green dark #235223, pastel siding light #ebebeb, lawn green light #5db15d, soot black #1b1b22, warm white #f2ede2, mid grey #7d828c, dark wood #3d2a1c. Every material's `name` must be exactly the palette colour it uses — the GLB carries these names so the kit recolours as one; an unnamed material fails delivery. Kit knob: expose a param `houseColours` (0–1, default 0.5) for the kit's "House colours" setting wherever it makes sense on this part, and keep that id.

Note: Size: about 1.80 m long (mudguard to mudguard), 0.64 m wide over the handlebar grips and 1.08 m tall over the basket. It has a 1.06 m wheelbase and 0.68 m wheels (26-inch class). The origin is at the bottom centre, the tyres and the kickstand foot rest on y = 0, and the front faces +Z. The drivetrain is on the rider's right (-X). The exported model has 2,840 triangles. Every material is named exactly after a kit palette colour, and 7 of the 12 colours are used at the defaults. The exporter writes one material per mesh, so a colour name appears on several materials: recolour by name. The baked clip scene-motion (4 s, seamless) moves only parts on their own pivots. The wheels roll five whole turns on their axles. The cranks turn twice on the bottom bracket (a 2.5 : 1 gear), and the pedals counter-rotate on their spindles to stay level. The steering assembly (fork, bars, basket, lamp, front mudguard and front wheel) sways ±4.6° on the head-tube axis. The frame never moves. The chain is two static runs, and only the chainring turns. The steering pivots inside a 'steer-mount' node tilted 20° to the head-tube angle; the front wheel's rest rotation cancels that tilt. Params are baked into the GLB at their defaults and only change the geometry when the scene is rebuilt in the viewer. houseColours (kit 'House colours') picks the mudguard and chain-guard paint: pastel siding light (below 0.33), pastel siding (default) or pastel siding dark (0.67 and up). wheelRadius sets the wheel size, and the frame rides with the axles. saddleHeight raises the seat post. basket removes the front basket at 0. glb-lint reports 0 errors and 5 heuristic warnings: the material count is above the direction default because of per-mesh materials; duplicate same-colour materials; non-indexed flat-shaded geometry; intended overlaps where tubes join; and parts flagged as detached because they attach across groups. Its bounds line reads y 0..1.161 because it uses rotated boxes; a vertex-exact pass over the GLB gives 0..1.075. Its verdict line reads UNVERIFIED only because no host requirements contract was supplied. plan-check passes except for its part-id regex, which rejects the hyphens in the slug-based ids this library requires. three-check accepts those ids, and all 16 survive the GLB reload.

About the Bicycle 3D model
