Rider Fit	Its low seat height and light dry weight make it easy to manage for shorter or less physically strong riders.
Character	It has the quirky, minimalist charm of a boutique single, favoring simplicity and character over raw output.
Not Ideal For	It's not for riders seeking highway overtaking power, long-distance comfort, or off-road capability.

Units

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

Feet:

At 800mm, a rider of 175cm with a 79cm (estimated) inseam will reach the ground with both feet flat on the 2007 CR&S Cr&s VUN Underpowered, with a relaxed knee angle of around 120 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.
