Rider Profile

Best ForThis is an ideal machine for beginners, new riders, or those returning to two wheels after a long break, given its low power and gentle top speed.
PurposeBest suited as a lightweight urban commuter for short hops, errands, and learning basic motard-style handling rather than any performance riding.
Rider FitIts low seat height and light dry weight make it very accessible and easy to manage for riders of smaller stature or lower confidence.
CharacterThe Esum S Pro has a playful, minimalist, eco-conscious character, favoring simplicity and silence over speed or aggression.
Not Ideal ForThis is not the bike for riders seeking highway touring, spirited cornering at pace, off-road capability, or carrying a passenger any real distance.

Rider Fit Visualizer

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

Feet:

At 665mm, a rider of 68.9" with a 31" (estimated) inseam will reach the ground with both feet flat on the 2025 Kollter Esum S Pro, with a moderate knee angle of around 105 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.
