Rider Profile

Best ForThis is an entry-level machine well suited to brand-new riders or those wanting a simple, low-stakes commuter, despite its misleading 'Sport' category label which doesn't match its cub-style underbonnes construction and drum brakes.
PurposeBuilt as a small-displacement utility commuter for short hops around town rather than any kind of sporting or performance riding.
Rider FitIts low seat height, light dry weight, and automatic-style wet clutch make it extremely easy and unintimidating to handle for riders of almost any size or strength.
CharacterA humble, economical little runabout with modest single-cylinder power, basic drum brakes, and no pretensions beyond reliable, low-cost transportation.
Not Ideal ForThis bike is not for riders seeking real speed, highway touring comfort, passenger-carrying capability, or any kind of off-road capability.

2008 Jianshe Cub JS125-G Rider Ergonomics Assessment

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

Feet:

At 770mm, a rider of 175cm with a 79cm (estimated) inseam will reach the ground with both feet flat on the 2008 Jianshe Cub JS125-G, with a cramped knee angle of around 65 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.
