Best ForThis is an entry-level 50cc scooter suited to beginners, commuters, and younger or first-time riders often restricted by license class.
PurposeDesigned purely for short-hop urban commuting and running errands rather than any kind of performance riding.
Rider FitVery light and easy to manage at low speed with a low seat height, making it accessible to smaller or less experienced riders.
CharacterA practical, no-nonsense small-capacity scooter that prioritizes easy handling and fuel efficiency over excitement.
Not Ideal ForThis is not the bike for highway travel, long-distance touring, carrying a passenger comfortably, or anyone seeking real speed or performance.

2011 Aprilia SportCity One 50 Street Rider Ergonomics Assessment

Calculated in your browser only - your height/inseam are never sent to our servers.

Feet:

At 775mm, a rider of 175cm with a 79cm (estimated) inseam will reach the ground with both feet flat on the 2011 Aprilia SportCity One 50 Street, with a moderate knee angle of around 100 degrees and a slightly forward riding position.

Data quality: measured. Assumes about 30mm of suspension sag once seated (a typical street-bike rule of thumb - stiffer or softer suspension will vary). This is an approximation from category-typical geometry and generic body proportions, not a measurement of this specific bike or you - sit on it before you buy.
