Rider Profile

Best ForThis is an entry-level 50cc automatic scooter suited to new or young riders, often restricted by local moped licensing rules.
PurposeDesigned for short urban hops and light commuting rather than any performance or adventure riding.
Rider FitIts low seat height, light dry weight, and fully automatic transmission make it easy and unintimidating for smaller or less experienced riders to handle.
CharacterA simple, no-frills small-wheel scooter that prioritizes practicality, low running costs, and easy stop-and-go city use over excitement.
Not Ideal ForThis is not the right bike for anyone wanting real highway speed, long-distance touring comfort, or off-road capability.

2007 Beta Ark 50 X Rider Ergonomics Assessment

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

Feet:

At 830mm, a rider of 175cm with a 79cm (estimated) inseam will reach the ground with balls of both feet on the 2007 Beta Ark 50 X, with a moderate knee angle of around 105 degrees and an upright 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.
