Rider Profile

Best ForThis 50cc scooter is ideal for beginners, learners, or anyone needing a low-stakes introduction to two wheels.
PurposeIt's built purely for short-hop urban commuting and running errands around town rather than any kind of performance riding.
Rider FitIts light weight and low seat height make it easy and unintimidating for riders of almost any size or strength to manage.
CharacterIt's a nimble, no-fuss city runabout that prioritizes convenience and easy handling over speed or excitement.
Not Ideal ForThis is not the machine for highway travel, long-distance touring, carrying a passenger comfortably, or any kind of spirited or off-road riding.

2009 Derbi Atlantis 50 2T Bullet Rider Ergonomics Assessment

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

Feet:

At 790mm, a rider of 175cm with a 79cm (estimated) inseam will reach the ground with both feet flat on the 2009 Derbi Atlantis 50 2T Bullet, 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.
