Rider Profile

Best ForThis is an ideal machine for complete beginners or those wanting a simple, unintimidating first powered two-wheeler.
PurposeBuilt purely for light, low-speed urban commuting and short errands rather than any kind of performance riding.
Rider FitIts very low seat height and light dry weight make it extremely easy to handle for riders of almost any size or strength.
CharacterA humble, economical little scooter-style commuter that prioritizes ease of use, fuel efficiency, and low running costs over excitement.
Not Ideal ForThis is not suited to highway travel, touring, off-road use, or anyone seeking real acceleration or top speed.

2012 ShineTime ST125 SkyMax-Pro Rider Ergonomics Assessment

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

Feet:

At 740mm, a rider of 175cm with a 79cm (estimated) inseam will reach the ground with both feet flat on the 2012 ShineTime ST125 SkyMax-Pro, 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.
