Big Bear Choppers


This bike is our most aggressive and in your face design, packed with a hard core attitude. Don’t be concerned about that 20” over stock springer frontend, we’ve dialed in the frame and springer geometry so it feels and handles extremely well considering the wheelbase. You and everybody else will be surprised how well this bike takes the corners and its low speed maneuvering. With her radius dual downtube, a bold 48 degree neck rake, spoke wheels, swooping rear frame section, unparalleled curvaceous fuel tank and the long reaching springer, this vintage inspired rigid chopper rolls with new school technology. The Merc Rigid is perfect for the rider that wants to make a statement on the road that doesn’t mind the rigid ride. State-of-the-art technologies and pioneering design have united to create the most powerful vehicle today. Experience the ride of a born leader. Your Merc Rigid will never be forgotten.



Reliability, power and comfort... the best of all worlds. And when we say reliability, we not only mean the life of the engine, but the life of motorcycle and everything that's bolted to it. Branded as V111™,' this internally reformed 111 cubic inch engine boasts a healthy 122.8 lbs. of torque at the crank. With a configuration of a 4 1/8” bore and 4 1/8” stroke, proprietary compression ratios, redesigned cam timing, and reciprocating weights all result in an incredibly smooth running engine while meeting all the strict legal requirements. While looking like any other S&S Super Sidewinder engine from the outside, the essence of this new engine is the low vibration. High engine vibration is an enemy to both the rider and the motorcycle. The effects of high engine vibration may cause premature rider fatigue as well. Eliminate engine vibration and you will eliminate potential problems.


Transmission and Drivetrain

This is still the best built tranny to this day... hands down. This Detroit built tranny is designed and manufactured to comfortably handle the power from our engines while looking good behind it.


Keeping with the mindset of making form and function coexisting, this newly designed proprietary primary is built tough and reliable along with a very sleek, new generation styled aesthetics with a cool BBC branded inspection cover. This primary drive is approximately 200% stronger than most other manufacturer’s primaries with its machined forged aluminum inner and outer cases. The dense aluminum material makes for a unit that does not flex under heavy torque, and absorbs most engine vibration. Another great attribute that sets this primary drive ahead of the curve is the triple seal design on the main shaft, as opposed to an industry standard single seal, insuring virtually no leaks. The starter motor shaft accessory plate is removable for an easy starter change-out. The internals utilize an easy-to-replace standard type clutch basket and a compensating sprocket for a smooth power transfer.



We teamed up with Wire-Plus, the industry's leader in motorcycle electronics, to design a wiring harness with no compromises. Combine this harness with the high-end brand name electrical components like the Spyke charging system and the Crane ignition, and we're sure your seat time will be long. You won't be on the side of the road kicking rocks.



Frame and Body

The Merc Series motorcycles are our most aggressive chopper in our fleet with a 48° raked neck and style to kill. The double barrel shotgun type radius downtube is a very unique element in the frame design.

The frame is the foundation of the motorcycle's aesthetics and reliability. All our frames are designed and manufactured in house in our San Bernardino facility. Every frame component (e.g. neck, side plates, tank mounts, tranny plate, axle adjusters, etc) are CNC manufactured with precision. Utilizing a 0.250 wall, 1.5” tube steel for the backbone and 0.160 wall, 1.125” tube for the rest of the frame, BBC uses the best steel possible for our frames. All frames are 100% TIG welded for a clean, strong and precise fusion. We think we make a statement about our confidence with a lifetime warranty on the frames we make.

Like our frames, our tanks and fenders are designed and manufactured in-house. We produce the sheetmetal with the frame as a unit, then gets 'mock-up' before we hand it over to our painters or ship it out to the unassembled kit customers. We use heavy duty 12 gauge steel for our fenders and 14 gauge steel for the tanks. All tanks are pressure tested and the fenders are computer cut. We guarantee and warranty any leaks from the tanks and cracks in the fenders for your lifetime.


Designed and manufactured in-house, our fully chrome frontend is exclusively made for our motorcycles to be aesthetically cool and functionally bomb proof. The BBC logo branded 6° triple trees have what we call a 'smooth mount' design - you don't see the tube and axle nuts on top. And what we mean with the 'hidden axle' - it's a nutless type axle, making the finish smooth. With all our calculations with the frame and frontend, we've landed the front wheel in the sweet spot of the final trail measurement. This allows for a motorcycle with no frontend flop and high speed wobble.
