Rider Profile

Best For	This machine suits a patient, mechanically curious rider who values novelty and low running costs over performance, and is comfortable riding something with a top speed under 100 km/h.
Purpose	Built as a slow, ultra-efficient diesel-powered utility and curiosity bike rather than a performance or leisure machine, ideal for short-range practical use, demonstration, or fuel-frugal commuting.
Rider Fit	The single-seat layout, low 760mm seat height, and light dry weight of 165kg make it accessible to riders of varying size and experience, though the low power ceiling limits any physical demands to slow-speed handling.
Character	Quirky, thrifty, and mechanically distinctive, this diesel-engined oddity trades speed and excitement for remarkable fuel economy and low emissions, appealing to riders who enjoy unconventional engineering.
Not Ideal For	This is not the bike for anyone seeking spirited acceleration, sustained highway touring, passenger comfort, or aggressive cornering performance.

Feet:

At 760mm, a rider of 68.9" with a 31" (estimated) inseam will reach the ground with both feet flat on the 2014 Sommer Diesel 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.
