Bobber, Bob, earlier bob-job.
This is the earliest and very popular type of custom bikes. The style formed simultaneously with biker movement on southern Westcoast, USA, on the edge of 1940-1950-s. Early motorbike customizing developed in the same time as automotive hot-rod, and was, in fact, its two-wheel branch or, you could say, its “younger brother”. Some historians think that roots of bobbers are in pre-war “hill climbers” racing motorcycles. It is not necessarily right that custom building of racing motorcycles considers weight reduction. And, unlike choppers, people were eager to race riding bobbers on the bottom of alkali flat or.
So, bobbers were originated as specifically sportbikes. And, unlike choppers, these bikes couldn’t afford second seat, ape hangers etc. Classic bobber has wide wheels, low handlebar, short fork on low-neck frame and tightly built outline without any additions.
Though, today’s bobbers are not meant for races, but for style and еpatage. That’s why sometimes there are such chopper elements as ape hanger. But short fork, tightly built proportions and wide wheels are main peculiarity of bobber.
There was no high incidence of front fork on bobbers, because it detained in races.
Typical bobber in modern understanding is an old school bike with low handlebar, small slope angle of front fork and tires of the same size, as a rule, built on serial frame.
Bobber is a motorcycle, on which removed or reduced in weight all mechanisms, which don’t affect motorcycle’s driving qualities, but reduce its full weight.
Removed: speedometer, motometer, buzzer, front brake, windscreen, front fender, tail lamps, muffler, rear suspension…
Reduced/replaced: headlight, large seats, fuel tank, accumulator battery...
