Rider Profile

Best ForBest suited to experienced riders who are comfortable managing a long, heavy, raked-out custom chopper at low speeds.
PurposeBuilt as a boulevard and show-worthy custom cruiser, prioritizing stretched-out styling and big-inch torque over outright performance or cornering ability.
Rider FitThe low 23-inch seat height helps confidence at stops, but the 700-pound weight, extreme 40-degree rake, and long 83-inch wheelbase demand strength and deliberate input at slow speeds and in tight maneuvers.
CharacterA brash, high-torque S&S-powered chopper personality that rewards relaxed, straight-line cruising and turning heads rather than aggressive riding.
Not Ideal ForNot a good fit for riders wanting agile cornering, off-road capability, or a nimble daily commuter.

2009 Big Bear Choppers Devils Advocate ProStreet 100 EFI Rider Ergonomics Assessment

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

Feet:

At 584mm, a rider of 175cm with a 79cm (estimated) inseam will reach the ground with both feet flat on the 2009 Big Bear Choppers Devils Advocate ProStreet 100 EFI, with a cramped knee angle of around 70 degrees and a slightly forward 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.
