Rider Profile

Best For	This is best suited to absolute beginners, young riders, or those needing a low-powered moped-class machine to learn basic controls.
Purpose	It's designed as a small-capacity commuter runabout for short local trips rather than any kind of performance or adventure riding.
Rider Fit	Its light weight and low seat height make it extremely easy and unintimidating to handle for smaller or less experienced riders.
Character	It has a simple, old-school moped charm with modest four-stroke single-cylinder character and unhurried, gentle performance.
Not Ideal For	This is not for riders seeking real speed, highway capability, off-road ability, or two-up long-distance touring comfort.

Your height

Inseam (optional)

Units

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

Feet:

At 730mm, a rider of 175cm with a 79cm (estimated) inseam will reach the ground with both feet flat on the 2011 Jawa-CZ 50 Robby, 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.
