Rider Profile

Best ForThis is an entry-level machine best suited to beginners or those just stepping up from a small-displacement commuter.
PurposeIt is designed primarily as an affordable, low-maintenance runabout for basic urban transport rather than performance riding.
Rider FitIts light dry weight and low seat height make it easy to manage for smaller or less experienced riders.
CharacterSimple, unintimidating, and utilitarian, it favors fuel efficiency and approachability over excitement or refinement.
Not Ideal ForIt is not suitable for highway touring, spirited cornering, or any rider seeking strong acceleration or long-distance comfort.

2013 Sonik GPX 150 Rider Ergonomics Assessment

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

Feet:

At 790mm, a rider of 175cm with a 79cm (estimated) inseam will reach the ground with both feet flat on the 2013 Sonik GPX 150, with a moderate knee angle of around 115 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.
