Editing Three-wheeler (section)

== Overview ==
Many three-wheelers which exist in the form of motorcycle-based machines are often called trikes and often have the front single wheel and mechanics similar to that of a motorcycle and the rear axle similar to that of a car. Often such vehicles are owner-constructed using a portion of a rear-engine, rear-drive [[Volkswagen Beetle]] in combination with a motorcycle front end. Other trikes include {{pslink|All-terrain vehicles}} that are specially constructed for off-road use.

Three-wheelers can have either one wheel at the back and two at the front (2F1R), (for example: [[Morgan Motor Company]]) or one wheel at the front and two at the back (1F2R) (such as the [[Reliant Robin]]). Due to better safety when braking, an increasingly popular form is the front-steering "tadpole" or "reverse trike" sometimes with [[front drive]] but usually with rear drive. A variant on the 'one at the front' layout was the [[Scott Sociable]], which resembled a four-wheeler with a front wheel missing.<ref>{{cite web |url = http://www.motorbase.com/manufacturer/by-id/1723096431 |title=Scott Sociable |access-date=2015-10-05}}</ref>

Three-wheelers, including some [[cyclecar]]s, [[bubble car]]s and [[microcar]]s, are built for economic and legal reasons: in the UK for tax advantages, or in the US to take advantage of lower safety regulations, being classed as motorcycles. As a result of their light construction and potential better streamlining, three-wheeled cars are usually less expensive to operate.{{Citation needed|date=October 2015}}

Some inexpensive three-wheelers have been designed specifically to improve mobility for disabled people.<ref>{{Cite journal |last1=Stańko-Pająk |first1=K |last2=Bursa |first2=B |last3=Seńko |first3=J |last4=Detka |first4=T |last5=Korczak |first5=S |last6=Nowak |first6=R |last7=Popiołek |first7=K |last8=Lisiecki |first8=J |last9=Paczkowski |first9=A |date=2022-07-01 |title=A three-wheeled vehicle for the disabled people |journal=IOP Conference Series: Materials Science and Engineering |volume=1247 |issue=1 |pages=012039 |doi=10.1088/1757-899X/1247/1/012039 |bibcode=2022MS&E.1247a2039S |s2cid=250504234 |issn=1757-8981|doi-access=free }}</ref>

Three-wheeler transport vehicles known as [[auto rickshaw]]s are a common means of public transportation in many countries in the world, and are an essential form of urban transport in many developing countries such as India and the [[Auto rickshaw (Philippines)|Philippines]].
