Respostas curtas
Qual autoridade ou corredor local importa para este tipo?
Comece pela lente local: homologação, licenças e hubs — não uma checklist global.
Is this a buying guide?
No. Tool-Lifes /vehicles is an educational atlas. It explains history, systems and culture without affiliate rankings.
Are the scores official?
No. The six scores are relative editorial 0–100 marks across the 48 types on this site.
Where do the photos come from?
Lead images resolve from Wikimedia Commons via Wikipedia titles on the English masters, with licences recorded on the credits page.
Why metric units?
Metric is the default. Regional notes (US customary, local brand culture) appear in culture and market chapters.
How is this different from a wiki article?
Each type gets seven fixed-depth chapters, comparable scores and cross-type labs — structured for browsing, not a single freeform page.
Em Tuk-tuk, propulsão, estrutura, controlo e segurança partilham o mesmo envelope operacional.
Os medidores resumem margem estrutural, manutenibilidade e fatores humanos em pontuação relativa.
Sistemas
Estrutura
Tuk-tuk: Two rear driven wheels with single front steer wheel—or reverse delta layout—define tippiness and brake bias. Tubular or pressed steel frame carries body and engine.
Propulsão
Tuk-tuk: Single-cylinder or twin two-stroke or four-stroke engines (100–200 cc) drive rear axle via chain or shaft. CNG conversions common in polluted cities.
Energia
Tuk-tuk: Canvas roof, side curtains, and bench seat for 2–4 passengers; cargo variants drop seats for goods.
Controlo
Tuk-tuk: Older auto rickshaws use motorcycle handlebars; newer models adopt steering wheel and partial cabin.
Interface
Tuk-tuk: Three drum brakes with mechanical or hydraulic linkages—no ABS on most fleets.
Segurança
Tuk-tuk: Taximeter, roof sign, and municipal paint codes identify legal hire vehicles.
