Rider Profile

Best ForWell suited to beginners and new riders who want a simple, unintimidating machine to build confidence on.
PurposeDesigned as a basic commuter and light utility bike for short trips and everyday errands rather than performance riding.
Rider FitThe low seat height and light overall build make it accessible to riders of smaller stature or those with limited strength.
CharacterAn honest, no-frills small-capacity single that prioritizes simplicity, low running costs, and easy manageability over excitement.
Not Ideal ForNot a good fit for riders seeking highway touring comfort, high speed capability, or serious off-road performance.

2021 UM Max 125 XL Rider Ergonomics Assessment

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

Feet:

At 805mm, a rider of 175cm with a 79cm (estimated) inseam will reach the ground with both feet flat on the 2021 UM Max 125 XL, with a moderate knee angle of around 115 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.
