Rider Profile

Best ForThis is an entry-level moped-class machine best suited to absolute beginners, young riders, or those wanting a simple, low-stakes runabout.
PurposeIt's built for short, slow-speed errands and light neighborhood commuting rather than any kind of performance or long-distance riding.
Rider FitIts low seat height and very light dry weight make it extremely easy to handle and manage for riders of almost any size or strength.
CharacterThe Jawa 50 Robby is a modest, unassuming little machine with old-school charm, offering basic mechanical simplicity over speed or excitement.
Not Ideal ForThis is not the bike for anyone seeking highway travel, a passenger companion, off-road capability, or any real sense of performance.

2005 Jawa 50 Robby Rider Ergonomics Assessment

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 2005 Jawa 50 Robby, 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.
