Rider Profile

Best ForThis is an ideal machine for new riders or those wanting simple, low-stakes twist-and-go transport.
PurposeBuilt purely for short urban hops, errands, and commuting rather than any kind of performance riding.
Rider FitIts low seat height and light 95 kg weight make it easy to manage for riders of almost any size or strength.
CharacterA friendly, unintimidating little scooter that prioritizes ease of use and maneuverability over speed or excitement.
Not Ideal ForThis is not the bike for highway touring, carrying a passenger comfortably, or anyone seeking real performance.

2011 Piaggio Liberty 50 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 Piaggio Liberty 50, 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.
