LEGO-Legal GeometryA French microcar by Robert Hannoyer (“Reyonnah” is an ananym of Hannoyer), notable for folding front wheels to reduce parked width.
Vehicle width rule satisfied (≥ 8 studs). Larger sizes allow legal wheel-fold mechanism detailing.
Availability-first palette; substitutions included if a specific shade is scarce.
Moving features must pass clearance rules: no scraping, no pre-load, no forced alignment.
Customization baked in: color, stance, wheels, interior, details, or features can be updated after generation.
True LEGO Geometry & LEGO-Legal Rule Set (hard-baked):
Stud grid only • 1 brick = 3 plates • legal half-stud offsets via official elements (jumpers/brackets/headlights) • no stressed geometry • no jam-fits • stable at rest • Studio collision + connection validation: zero intersections, zero floating, all valid connections • moving features require clearance & straight pin/axle alignment.

Key facts (compiled):
• Maker: Robert Hannoyer (France). “Reyonnah” is an ananym of Hannoyer.
• Layout: tandem seating (driver front, passenger behind). Rear-mounted single-cylinder engine (175cc / sometimes 125cc) driving rear axle via 3-speed gearbox and chain drive.
• Signature feature: folding front wheel structure to reduce parked width (narrow “storage” track; wider “driving” track for stability).

Real-Build validation requirement (hard-rule):
After building in BrickLink Studio, run collision + connection checks until you have: zero intersections, zero floating, all valid clutch connections. Any moving feature must have clearance and must not rub panels or preload linkages.

Real-Build Update Notice:
If you see a duplicate Reyonnah generator on the site, use the one labeled “Real-Build logic version”. If this page is already current, it will generate the build plans (not a new generator).
