Rider Profile

Best ForThis scooter is best suited to new riders or anyone wanting simple, low-stress transport without a manual gearbox to worry about.
PurposeIt's built for short urban hops, commuting, and running errands rather than any kind of performance riding.
Rider FitIts light weight and low seat height make it easy to handle and paddle around at a stop for riders of most sizes.
CharacterA friendly, practical little automatic scooter that prioritizes ease of use and maneuverability over speed or excitement.
Not Ideal ForIt's not for riders wanting highway performance, long-distance touring comfort, or any off-road capability.

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

2011 Derbi Atlantis 50 4T Rider Ergonomics Assessment

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

Feet:

At 795mm, a rider of 175cm with a 79cm (estimated) inseam will reach the ground with both feet flat on the 2011 Derbi Atlantis 50 4T, 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.
