Why is Geared Belt Drive better than
Friction or Chain Drive?

  • No excessive tension, friction
    or vibration to
    cause bike parts to fatigue, engine to
    wear out or burn
    tires up.
  • The geared belt is a more
    efficient (and
    less expensive) method of transferring
    power from engine
    to wheel – ever wonder why
    motorcycle manufactures
    now use the geared
  • Better traction under any
    conditions: rain,
    puddles, muddy roads, snow, sand,
    trail riding or
    on the road.
  • No rollers to rub hole in
    tire, especially
    when wet – even ‘morning dew’
  • Pressure is evenly distributed
    to the entire wheel
    not just the tire; Will not cause
    the rim to warp
    or excessive tire wear.
  • Positive drive system allows
    for more efficient
    power transfer from engine to
  • Simple, Easy to change drive
    gears for multiple
    riding conditions – No adjustment
    or re-alignment
  • Our smaller, Quieter, lighter
    engines yield much
    better gas mileage And
  • Easy to engage belt tension
    lever for pedaling
    or engine use.
  • No dangerous lever on
    handlebar to impale
  • No heavy gear boxes to add
    excessive weight
    and suck up the engine’s
  • Our Lightweight, Trim unit
    sits well within
    the pedal crank and below the
  • No limitation of tire
    selection: aggressive,
    trail or street.
  • You can even keep your fender,
    You’ll be able to’t do That
    with a friction (scrubber)
  • GEBE’s well balanced design
    allows use of kickstand
    that came with your

Golden Eagle’s patented
geared belt, positive drive
system allows for a more
power transfer, from the
engine to the wheel, over
drive or gear reduction
chain drives. You do not
have to put
up with a big, noisy (oil
spitting) engine to achieve
performance, speed or pick-up.

Many of our customers are commuters, disabled
seniors – GEBE is committed
to providing reliable,
transportation. Our 2-Stroke
and 4-Stroke engines are
extremely well built for
long life, dependability
and fuel
efficiency, whilst meeting
Carb Tier II EPA requirements.
Coupled with our efficient,
geared belt power transfer
results in the most dependable,
easy to install and use,
mileage and environmentally
friendly bicycle assist
engine kit

Easy assembly
and installation usually
requires only 30 minutes
to 1 hour.
Snap the Drive Ring on
the rear wheel, install
four nuts and
bolts, one screw for the
kill button and slide the
mount strap
into place on the rear
axle. The trigger throttle
clips on
your handlebars for use
with your thumb or finger,
is more comfortable for
you to use. We recommend
you have

The trigger throttle is spring loaded – pull
the trigger to go – release
the pressure to slow down
or come
to a complete stop. There
is no shifting of levers
or any type
of clutch movement necessary
for stop and go riding.

The automatic centrifugal
clutch allows engine to
disengage when you let
off on the gas
to slow down, stop or idle

of your car. No dangerous
levers to push! Control

The Drive Ring is made of
nylon, reinforced gear
material, for long life
and durability.
Fits 24″, 26″ or 700c wheels
with 32 or 36 spokes. Rotate
ring over your wheel until
the spoke slots align with
spokes, using our 4n1 Ring/Spoke/Gear
Key; the spokes easily
click into the slots. Securely
fits most spoke sizes from
gauge to 12 gauge.

With our
patented design, the drive
ring is self centering,
there is no
adjustment – one piece
to install and it doesn’t
come off
easily. The Drive Ring
requires 1 1/4 inch between
the rear
fork and the spokes for
proper clearance.

The geared Drive Belt is Kevlar reinforced
long life and durability.
Although most of our customers
the belt will last for
more than a year, riding
style dictates
belt life. Breaking strength
of 1280 lbs. Extend the
life of
your belt, reduce stress
and pedal a stroke or two
as you take
off or accelerate.

The unit
comes with a Safety Cover
(made of recycled plastic)
for the
moving parts.

One eighth
inch clearance is required
on each side of the axle
for the
Lower Mount Strap, a total
of 1/4 inch. There is ample
room on
most bike axles for the
lower mount strap.

The GEBE mount kit will fit even the larger
diameter tire sizes – up
to 26 x 2.125

Since Golden Eagle entered the scene in 2001,
we’ve watched our competitors claims double
on performance but they still use the same
engines(?). Their units have jumped from
120mpg to 200mpg and 25mph to 45mph – BUT,
there have been No changes to the mount and
they still use the same engines(?). How’d
they do that? GEBE lists the Total weight
– engine and mount – they only list engine
weight. We post performance of our engines
with a 200+lb rider and DB’s are measured
3ft (or distance from engine to rider’s ear).
You can count on receiving performance within
5% of GEBE claims

Honda GX35 1.6hp OHC Mini 4 Stroke

Honda applied their superior engine technology
to create the world’s first 360° inclinable
4-Stroke engines. The ultra-lightweight GX35
Mini 4-Stroke efficiently delivers the kind
of efficient cleaner, powerful, quiet performance
that you’d expect from a larger engine –
but in a very compact package.

Performance Curve

Approximately half the operating cost of
comparable 2-stroke engines

Efficient 4-Stroke technology
not only offers
superior fuel economy,
it also requires no
mixing of oil in the engine’s
fuel supply.
This substantially reduces
both oil consumption
and the emission of unburned
oil in the exhaust.

An exclusive Honda rotary-slinger
system keeps oil in a completely
misted state
and circulates it using
pressure fluctuations
generated by the movement
of the piston.

Built-in passages effectively
return the
circulated oil to the oil
reservoir from
every part of the engine.
An oil return port
positioned in the center
of the reservoir
prevents oil from accidentally
flowing into
the combustion chamber.

The results include better
all-around environmental
performance and operating
costs that actually
decrease the more the engine
is used!

Belt-driven OHC design

In addition to the milder
operating noise
of 4-Stroke engines in
general, the Mini
4-Stroke’s belt-driven
OHC design further
reduces unpleasant mechanical
noise. Its
lighter piston and other
moving parts help
keep vibration to a comfortable

GEBE offers three, easy
to change drive gears
, an allen wrench (5/32″ or 4mm), our
new 4-N-1 ring/spoke/gear
Key and a few minutes
are all that is needed
to change gears. The
tension arm automatically
adjusts for proper
belt tension with all three
gears, no additional
adjustment is necessary.
The Standard gear
(included with kit) allows
speeds up to 27-28mph,
is great for most terrain
– street, highway
and moderate hills/trails.

** The Trail gear (sold separately) has more low-end torque
– is better for off-road,
more hilly areas
or pulling a heavier load.

** The Highway gear (sold separately) has less low-end torque
– is better for more level
ground for a faster
commute and higher mileage

  • There is a 10% difference in top speed between
    the Trail, Standard,
    and Highway gears.

** IMPORTANT! Kits are NOT designed to mount on a Quick
Release axle. The Quick Release should be
replaced with a standard solid axle (available
at most bicycle shops), comes with cones
and bearings. – OR – You’ll be able to purchase a Replacement
axle from GEBE that fits the cones and bearings
of the 10mm Fine(most common) or 1.25mm Coarse
(Rare) quick release axle.

** IMPORTANT! Check and tighten all nuts, bolts and spokes
on the bike and mount kit Before taking off
for your New Adventures in cycling. Nuts,
bolts even spokes will seat as they adjust
to the new speeds you are traveling – Re-check
and Re-tighten All nuts and bolts after 1st
gallon running time – even the front and
lower mount straps, knob on tension lever
arm and spokes. When you’ve run a few gallons
out, the nuts, bolts and spokes should have
seated and you shouldn’t have to check as
ceaselessly. With any piece of transportation,
it is prudent to perform routine bike and
engine maintenance (see manual). Depending
on the number of miles, your particular bike
and individual riding style, frequency will

DO NOT Over-tighten
spokes. Normal torque on
spokes is all that is required.
Wheels have an automatic
bow when cornering fast,
tightening spokes can cause
them to break when making
turns at fast speeds.

NOT torque down on the
nut (pivot point) on belt
tension lever
arm. A lock nut is pre-set
from factory, you don’t
want it
loose but to torque it
down causes improper belt
tension and
adversely affects free
movement of the tension
arm. This arm
must pivot freely for proper
alignment and belt tension.

We DO NOT recommend you
motorize a 27″ touring
bike, the rims and spokes
of these
bikes may not hold up well
to the pounding they will
take at
Eagle speed.

**IMPORTANT** DO NOT modify mount parts or change any
angles – any changes will effect performance
and/or operation and could void Warranty.


We recommend dual brakes and that they be
in good condition,
replace pads if

Frequently Asked

Depending on the engine you get – Total weight
of engine and all mounting parts range from
12 lbs to 14 lbs.

  • How loud are the engines?
All small engines are between 70db’s at Idle
to 85 db’s at Full Throttle. 4-stroke engines

“Quiet” reputation – the 2-stroke
Tanaka is, also, in this category.
  • Can I pedal with out the engine running?

YES…One of the crucial features of our kit is that
You’ll be able to disengage
the belt tensioner with
a flip of a
small lever and the bike will
pedal like

  • What kind of fuel does it take?

The 2-stroke engines use Unleaded Gas, 87
octane or better with Quality 50:1 2-stroke

  • Would a bicycle shop be a good place to take
    my Eagle for installation?

No, many bicycle shops have a negative attitude,
in terms of motorizing a bike, they
feel everyone should be in Lance’s physical
condition. If you don’t have the time (or
the inclination) to do the installation yourself,
take the unit to your neighborhood lawn and
garden repair – these folks are familiar
with engines And which end of the screwdriver
to use!

  • When you say “pedal a few strokes”
    on take-off, what
    speed do you recommend
    before pulling
    on the throttle?

You don’t have to pedal up to any certain
speed, just a few strokes to start the bike
rolling, as you ease on the throttle. Taking
off from a traffic light, I At all times pedal
a few More strokes for a Faster take-off.
When I say ‘ease’ on the throttle, I mean
– Don’t Yank it! Treat the machine with a
little respect and you’ll be able to be rewarded for
a Long time – these are Bicycle engines Not
motorcycles (although some of these engines
might argue that opinion;).

  • What features should I look for in a bike
    – Specifically
    to motorize?

Specifically? 36 spoke (Stainless steel spokes)
wheels, solid axle (not a quick release)
and Rim brakes will simplify the process
– Then #1, find a bike that’s Comfortable
for You! Fenders, rear view mirror, speedometer
and a Nice Fat Comfort Saddle, our customers
find they spend a Lot more time on their
Eagle than they Ever did on a pedal bike.

  • Any problems reported with Disk brakes?

Some disk brakes only require the lower mount
strap be spaced out with a nut/washer for
proper mounting – Others find they have to
grind a 1/4″ wedge from the lower strap
to clear the brake, still others require
Serious modification of the mount and would
not be recommended.

  • Can I mount an Eagle top my Mono-shock bike?

Yes. The front mount strap is attached to
the fender bolt hole (Not the seatpost),
the securely mounted engine moves With the

  • What are the belts made out of?

The belts are a Kevlar based material; (what
bullet proof vests are made of) for super
long life and strength.

  • How do I turn them off or stop the motor?

The Golden Eagle standard kit comes with
a simple kill button You’ll be able to attach to your
handlebar – OR – flip the engine choke lever
On/forward to kill the engine.

  • Do I need a driver’s license to ride one
    of these?

No, in most states our kit does not classify
as a motor vehicle/moped. Check your local
laws to be safe.


The chief engineer here at Golden
Eagle designed
the friction drive unit that was
chosen as “Official
Transportation” at the
Knoxville Worlds
Fair in 1980. Having worked on
friction drives
for several years he became
acutely aware
of the pitfalls and drawbacks of
this type of
design SO it was back to the drawing

The first
prototype we
built was made from the belt off a
cloths dryer,
weed trimmer engine and
tray. Now, after years of design
changes and
testing, he has come up with a design
we consider
better then anything on the market.
Better performance,
better mileage, less wear on
the engine


At Golden Eagle it is our goal to
provide the
most dependable and affordable
for young and old alike. To
continue to
work on research and development of
the best bicycle
assist device available, and
provide transportation
