Rider Profile

Best ForThis is an entry-level, low-powered moped-class machine suited to complete beginners or very young riders, not experienced motorcyclists.
PurposeIt is designed as a basic, economical runabout for short, low-speed errands rather than any performance or adventure riding.
Rider FitIts very low seat height and tiny 78 kg weight make it accessible and easy to manage for small or lightweight riders, including teenagers.
CharacterIt has a friendly, unintimidating scooter-like personality with a top speed of just 45 km/h, prioritizing simplicity and ease of use over excitement.
Not Ideal ForThis is not for anyone wanting real touring capability, highway speeds, off-road use, or carrying a passenger any real distance.

2012 ShineTime ST50 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 ST50 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.
