Rider Profile

Best ForThis is a machine best suited to experienced riders who are comfortable managing a long, heavy, rigid-frame chopper at low speeds.
PurposeBuilt as a bold custom cruiser for show-and-go boulevard riding rather than any kind of practical transportation or performance riding.
Rider FitThe extreme rake, low seat, forward stance, and rigid rear end demand a relaxed but deliberate riding style, with real physical feedback transmitted straight through the frame on rough pavement.
CharacterA brash, attention-grabbing hardtail chopper with a big torquey S&S-fed V-twin, prioritizing style, sound, and presence over handling precision.
Not Ideal ForThis is not for riders wanting nimble cornering, off-road capability, long-distance touring comfort, or a forgiving ride over bumps.

2015 Big Bear Choppers Merc Rigid 111 Carb 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 2015 Big Bear Choppers Merc Rigid 111 Carb, 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.
