Rider Profile

Best ForThis 50cc automatic scooter is ideal for beginners, learners, or anyone needing a simple, low-risk way to get around, with no clutch or gear-shifting skills required.
PurposeIt's built purely for short-hop urban commuting and running errands, not for speed or distance.
Rider FitIts light dry weight and low seat height make it very manageable for riders of smaller stature or those wanting an easy, unintimidating ride.
CharacterIt has a friendly, practical, and unassuming personality suited to relaxed city cruising rather than thrills.
Not Ideal ForIt is not suitable for highway travel, long-distance touring, carrying a passenger comfortably, or any off-road use.

2007 Beta Ark 50 AC 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 AC, 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.
