Rider Profile

Best ForThis is a mini-moto styled machine best suited to beginners, young riders, or those wanting a low-stakes learner bike rather than an experienced rider seeking performance.
PurposeDespite its supermotard styling with inverted forks and twin discs, its 50cc two-stroke engine and 45 km/h top speed make it a novelty or learner bike rather than a genuine sport or commuter machine.
Rider FitThe low 860mm seat height and lightweight small-displacement build make it accessible and unintimidating for smaller or less experienced riders.
CharacterIt mimics the aggressive supermoto look with alloy wheels and disc brakes front and rear, but the tiny two-stroke motor means its real character is playful and unhurried rather than aggressive.
Not Ideal ForThis is not the bike for highway commuting, touring, carrying a passenger, or any rider expecting real speed or performance.

Character map is an editorial estimate based on this bike's specifications, not a lab-tested measurement.

2012 Orion Hyeng AGB-31-2 Rider Ergonomics Assessment

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

Feet:

At 860mm, a rider of 175cm with a 79cm (estimated) inseam will reach the ground with tip-toe one foot on the 2012 Orion Hyeng AGB-31-2, with a relaxed knee angle of around 130 degrees and a forward-leaning 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.
