Rider Profile

Best For	This bike suits an experienced rider comfortable with a low, long, heavy custom cruiser rather than a beginner.
Purpose	Built as a stylish, low-slung custom bobber for cruising and showing off rather than for speed or long-distance touring.
Rider Fit	The very low seat height and relaxed cruiser stance make it accessible for shorter riders, though the long wheelbase and weight demand some upper body strength at low speeds.
Character	A big, laid-back V-twin cruiser with custom bobber styling, valuing looks, sound, and low-speed presence over outright performance.
Not Ideal For	This is not the bike for riders wanting sharp cornering ability, off-road capability, or serious high-mileage touring comfort.

Feet:

At 635mm, a rider of 68.9" with a 31" (estimated) inseam will reach the ground with both feet flat on the 2021 Ultra California Kid Bobber, with a cramped knee angle of around 70 degrees and an upright riding position.

Data quality: estimated (wheelbase estimated from this category's typical bike, not this model's own spec). 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.
