THE MOST RELIABLE,
„Geroth“ Bicycle Auxiliary Motor.
It seems rather superfluous to point out in our modern time
the importance of the bicycle for professional and for sporting
purposes. If we will say some words about this subject it is only
with regard to the revolution caused by the appearance of the
bicycle auxiliary motor. It is doubtless that this event signifies
the inauguration of a new epoch as well for the sportsman as for
such persons who must use the bicycle as often as their profession
requires in order to get over quickly considerable distances. The
simple and small but however extremely capable and cheap
bicycle auxiliary motor enables it to travel in a very short time
a great distance quite independent of the railway or any other
means of communication. No physical strain will be necessary in
future and the cycling will become a pleasure even for such cyclists
which are compelled to make frequent use of a bicycle, if they
are enabled to reach- their destination without any exertion and at
a speed of about 50 km per hour.
Therefore an auxiliary motor constitutes the ideal for innume=
rable cyclists as it can be mounted on every cycle without any
difficulty and in the simplest manner, and it can be also taken
away without any trouble. The
,GEROTH” AUXILIARY MOTOR
corresponds perfectly to all exigencies of practice.
This motor is constructed with all modern improvements existing
at the fine of combustion engines. A special attention has been
given to the fuel consumption in order to obtain the utmost economy
in working.
The design of our motor is a very happy one. The designer
could dispose of a great deal of experience in the building of small
motors, and owing to the fact that our works are equipped
with the most modern machines for the motor building we
began the series manufacture on a big scale. Ihis has the
considerable advantage that all parts are interhangeable without
any difficulty and can be furnished promptly by our factory.
We use only first class materials manufactured in our
own works and for which we give full guarantee,
Every motor hasto stand a rigorous test of continuance after
its achievement and there is not one piece that leaves our estab=
lishment before it does not work in a perfect manner, The con-
firmation of the above may be found in the excellent reputation
of our firm which, since ted in the simplest
manner upon every
solidly constructed tou=
many years, occupies
a prominent position in
the motor building fine.
This motor is a
precision engine in
the real sense of the
word and has confir=
ring cycle. By mounting
a belt felly upon the
bak=wheel and a sup-
porting fork, every
ordinary bicycle can
med this completely be transformed into a
by long and thorough motor=cycle within a
trials. It can be moun= very short time. We
give in the following a description of the little mechanical wonder
designed in the most ingenious manner.
1. Motor. The motor weighs only 10 kgs without fuel and there=
fore it constitutes the lightest auxiliary motor. It works
without valves by the two stroke cycle and at the three-way
system. The bore is of 50 mm, the stroke of 60 mm, which
corresponds to a useful work of 1'8 HP at the necessary number
of revolutions, Alf shafts and the cross head end of the connec-
ting rod are running in large sized precision ball-bearings,
whereby any wear, danger of running hot or waste of power are
completely eliminated.
2. Magneto. The high=tension magneto-ignition is mounted in the
fly=wheel in order to reduce the weight, it is suffi=
ciently protected against every prejudicial influence by the fly=wheel
casing of aluminium and secures a very intensive formation of
sparks by means of a sparking plug. The mounted regulator of the
time of ignition enables it to regulate the number of revolutions
without any change of the gas quantity. On this way only the
highest capacity of a machine can be obtained.
3. Carburettor. The carburettor is a floatless one and secures
the utmost economy of fuel, it is fitted with a
throttle valve for the governing. The nozzle, which is easily inter=
changeable, can be cleaned even while cycling in case that any
foreign substance should penetrate into it <chokings) evitating by
this way any trouble of dismantling the nozzle on the road.
4, Lubrication. The lubrication of all moving parts is performed
automatically because 8-10°/, of oil are added
to the fuel whereby all parts of the motor are sufficiently oiled
even under the most unfavourable circumctances.
5. Power transmission. The transmission of power is effectuated
by a conical disc=pulley of steel-sheet
keyed on the driving shaft by means of a wedge-shaped belt that
drives a similar disc=pulley mounted on the back-wheel. By an
ingenious device any slipping away of the belt is practically eliminated.
6. Management. The motor can be attended by two levers which
are fixed on the handle-bar whid disposition is a
very Simple one and will be clear to every cyclist without any trouble.
7. Cooling. The cylinder is cooled by farge sized cooling ribs which
prevent any overheating of the cylinder even at a low speed.
8. Fuel consumption. The benzine tank is for a contents of about
2 litres and is sufficient for a trip of about
120 km, that proves the economical working of our carburettor.
9, Riding capacity and speed. The riding speed can be raised
from the lowest up to the highest
pace of 45 km and more (on the race-course there has been
attained a speed of more than 60 km), The motor works also
at steep slopes with a regular number of revolutions and preserves
by this way the driver of any troubles.
10. Guarantee. All parts of our motor are scrupulously tested
before they are assembled. After the assembling
every motor of our production is rigorously tested on the power
brake and leaves our works only if all trials have proved satisfactorily.
11. We pack with every motor the necessary tools and are always
well stocked with spare parts. An instruction for the mounting of
the motor will be added likewise, however, we recommend to
charge our works with that labour where it will be done in the
best and cheapest manner,
12. If we resume, we believe that our above assertion is fully
justified i. e. that with our bicycle auxiliary-motor ,,Geroth’” we
habe brought in the market a fully reliable, durable, economical
model of the highest capacity. All practical trials are proving this
and we sell this instrument with the certainty to offer thereby a
first class mark adapted as well for the sportsman as for the
private cyclist. We are quite convinced that the excellent results
obtained till now by our bicycle auxiliary-motor ,,Geroth” will
continue and also endow the best success in future.
