Rider Profile

Best ForThis is a niche machine best suited to riders curious about diesel-powered utility bikes rather than performance, and beginners can handle it easily given its low power and top speed.
PurposeBuilt as a rugged, low-maintenance workhorse for slow utility riding, farm or military-style duty, and fuel-efficient short trips rather than sport or leisure touring.
Rider FitThe upright, single-seat riding position and low 760mm seat height make it accessible to riders of varying size and fitness, with minimal physical demand given the low speeds and light clutch action.
CharacterA quirky, torquey, single-cylinder diesel oddity with agricultural engine roots, valued for extreme fuel efficiency and durability rather than excitement or speed.
Not Ideal ForThis is not for riders seeking speed, cornering thrills, long-distance comfort, or passenger-carrying capability.

2014 Sommer 462 Rider Ergonomics Assessment

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

Feet:

At 760mm, a rider of 175cm with a 79cm (estimated) inseam will reach the ground with both feet flat on the 2014 Sommer 462, with a moderate knee angle of around 115 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.
