INTRODUCTION
The Pocket bike -PB-G02 is designed and built for use on a paved closed
circuit track. The track should be clean and without obstacles of any kind.
Qualified adults and younger persons can drive the pocket bike. Children
can drive the pocket bike only under the supervision of a responsible
adult person. The pocket bike is constructed especially for racing competitions on
special racing tracks. The pocket bike uses a single-cylinder two-stroke, Gasoline
combustion engine, and has an air filter and exhaust silencer. Transfer of power to
the rear wheel is through a drive chain. The overall drive ratio to the rear wheel
can be changed by the replacement of chain sprockets. The front and rear wheel
is equipped with disk brakes. The rear brake is controlled with the left fever

UNPACKING AND SETTING UP BEFORE RIDING
The pocket bike is delivered in a cardboard carton and packed with folded
handlebars and brake levers. After unpacking, set up the handlebars into the position,
that suits the best for driving. The maximum pulled brake lever position should not
touch on the handlebar grip. After setting up, tighten the handlebar nuts 1, brake
lever bolts 2, and the throttle assy. Bolts. See, Fig. 1. The level of foot rest's can be
regulated by loosening the bolt M5 (914.003.01) on the handle of the foot rest
(139.001.01). The foot rest can be moved to the front or back position. It is
recommended to try and check the position of handlebars and foot rest's individually.
While tightening the bolts and nuts, do not use an excessive force as to not damage the
threads, or distort the tubes and other parts. Verify the smooth and perfect function of
the Bowden cables to throttle and both brakes. Fill the fuel tank with fuel. (Gas-oil
mix) Failure to use the proper oil mix ratio will result in Engine damage for which you
will be responsible. Operating controls:
