Rider FitThe tall seat height and light dry weight favor riders of average to above-average height and confidence with a firm, sporty riding position.
CharacterA sharp, minimalist single-cylinder machine that rewards spirited, engaged riding with quick handling and strong braking feel.
Not Ideal ForNot a good fit for riders seeking long-distance comfort, wind protection, or high-speed touring capability.

2010 Beta M4 4T Rider Ergonomics Assessment

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

Feet:

At 870mm, a rider of 175cm with a 79cm (estimated) inseam will reach the ground with tip-toe one foot on the 2010 Beta M4 4T, with a relaxed knee angle of around 135 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.
