Rider Profile

Best For	Best suited to riders who already have some experience with heavy, low-slung cruisers and are comfortable managing weight at low speed.
Purpose	Built for laid-back boulevard cruising and style-focused riding rather than outright performance or long-distance touring.
Rider Fit	The low seat height and wide handlebar suit riders of average to tall height, but the substantial wet weight demands reasonable strength for maneuvering at a standstill.
Character	A muscular, blacked-out custom cruiser with fat tires and a punchy V-twin that rewards relaxed, torque-driven riding over aggressive cornering.
Not Ideal For	Not a good fit for riders seeking sharp handling, off-road capability, or a nimble machine for tight, technical roads.

Inseam (optional)

Units

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

Feet:

At 663mm, a rider of 175cm with a 79cm (estimated) inseam will reach the ground with both feet flat on the 2015 Harley-Davidson Dyna Fat Bob, with a cramped knee angle of around 70 degrees and an upright 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.
