Golden Eagle’s patented geared belt, positive drive system allows for a more efficient power transfer, from the engine to the wheel, over friction drive or gear reduction chain drives. You do not have to put up with a big, noisy (oil spitting) engine to achieve desired performance, speed or pick-up.
Many of our customers are commuters, disabled or seniors – GEBE is committed to providing reliable, affordable motorized bicycle transportation. Our 2-Stroke and 4-Stroke engines are extremely well built for long life, dependability and fuel efficiency, while meeting Carb Tier II EPA requirements. Coupled with our efficient, geared belt power transfer system results in the most dependable, easy to install and use, best mileage and environmentally friendly bicycle assist engine kit available.
The Golden Eagle gas bicycle mount kit without the engine is available for you “Do It Yourself ‘ers” ( diy ); those who can’t afford the Best but have a good engine gathering dust in the garage and for the ‘unfortunates’ – deceived by our competitor’s claims. Clean that engine off and four bolts will attach it to the GE drive. These gas powered bicycle Mount Kits without Engine fit flat-head engines with either a 52mm or 76mm clutch. **Click for Details** Recycle that engine, put it on the Golden Eagle drive and learn how that engine really Wants to perform!
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, whichever is more comfortable for you to use. We recommend you have front And rear brakes on your bicycle.
ALL components of the Golden Eagle drive – mount unit, drive ring, gears, belts, throttle – are 100% made in the USA – to US standards and provide American jobs. The mount parts are stamped US steel with a rust proof coating. The trigger throttle is spring loaded – pull on 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 – like the automatic transmission of your car. No dangerous levers to push! Control of bike can be maintained at all times with Both hands on the handlebars!
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 the ring over your wheel until the spoke slots align with wheel’s spokes, using our 4n1 Ring/Spoke/Gear Key; the spokes easily click into the slots. Securely fits most spoke sizes from 15 gauge to 12 gauge. **Click here for ‘How to’ use our 4n1 Key**
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 a minimum of 3 and 3/8 inches between the inside of the forks, when measured 8 & 1/2″ up forks from Top of the axle, for proper clearance. Be sure to check both upper and lower fork, some bicycle manufacturers squeeze one but not the other. **Click here for How to measure**
The geared Drive Belt is Kevlar reinforced for long life and durability. Although most of our customers find 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 custom molded Safety Cover 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 Eagles’ motorized bicycle entered the scene over a decade ago, we’ve watched our competitors claim double on performance but they still use the same engines(?). Their units have jumped from 120mpg and 25mph to 200mpg and 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.

News Archives

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 belt?
  • 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’ wet.
  • 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 wheel.
  • Simple, Easy to change drive gears for multiple riding conditions – No adjustment or re-alignment required.
  • Our smaller, Quieter, lighter engines yield much better gas mileage And performance!
  • Easy to engage belt tension lever for pedaling or engine use.
  • No dangerous lever on handlebar to impale rider.
  • No heavy gear boxes to add excessive weight and suck up the engine’s power.
  • Our Lightweight, Trim unit sits well within the pedal crank and below the seat.
  • No limitation of tire selection: aggressive, trail or street.
  • You can even keep your fender, you can’t do That with a friction (scrubber) drive.
  • GEBE’s well balanced design allows use of kickstand that came with your bike.

How much does the bicycle engine kit weigh?

Individual Engine Specs are listed on the INFO page, depending on the engine – Total weight of engine and all mounting parts range from 12 lbs to 14 lbs.

How loud are the motorized bike engines?

All small engine are between 70db’s at Idle to 85 db’s at Full Throttle. 4-stroke engines are in the same range, it’s the Tone many find less irritating that results in the “Quiet” reputation – the 2-stroke Tanaka is, also, in this category.

Can I pedal without the engine running?

YES…One of the features of our kit is that you can disengage the belt tensioner with a flip of a small lever and the bike will pedal like normal.
You won’t feel much drag, pedaling the 25.4cc RedMax for short distances, with tension lever off. Pedaling longer distances and for engines with larger clutches, it’s much easier to remove belt from drive ring. It takes seconds:
1) With tension lever off, roll bike a few inches as you lift belt from track of drive ring,
2) *Carefully* flip tension lever back to on position, belt will be held in position on drive gear, ready for reinstallation of belt.
3) Loop belt out of the way (many just loop over knob) twist tie, if you wish. Takes less than 1 min. To replace, re-route belt for engine use.

What kind of fuel does the bicycle motor take?

The 2-stroke engines use Unleaded Gas, 87 octane or better with Quality 50:1 2-stroke mixing oil for Air Cooled engines – we Highly recommend synthetic Blends, not straight synthetic.
For the 4-stroke engines, 87 octane, or better, is recommended and the oil you find runs best in your auto and/or recommended for weather conditions in your area, consult your Engine Manual.

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

No, many bicycle shops have a negative attitude when it comes to 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 always 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 rewarded for a long time – these are bicycle engines not motorcycles (although some of these engines might argue that opinion).

Which engine is recommended as commuter transportation?

A general ‘rule of thumb’ would be to recommend a 2-stroke engine, most commuters are looking for the fastest speed – 2-strokes are faster and made to run full throttle all day (with 4-strokes, it’s recommended to back off the throttle slightly for long range cruising).

What kind of oil should I use for my bicycle engine?

For 2-stroke engines, use a quality oil expressly labeled: 50:1 Two Stroke Mixing Oil for Air Cooled Engines – and only mix it 50 parts gas to 1 part oil. We highly recommend synthetic blends as opposed to straight synthetics.
4-stroke engines take automotive oil – and whatever is recommended for your temperatures. Consult your engine manual.

How do I change the oil in my 4-stroke, without having to turn the motor bike upside down?

With a basting bulb – and don’t grab the one out of the kitchen – Unless you’re fast! A 3 – 4 inch piece of gas line (auto parts) stuck on the tip of the baster will facilitate the job.

My wheel has 32 spokes and has held up well to my 25cc Eagle bicycle motor kit, will it hold up to larger engines?

We strongly recommend you have a 36 spoke wheel for engines 30cc and larger.

I have a 35cc 4-stroke, my 26 wheel spokes are 14 gauge but the spokes occasionally break - any fix?

Replace spokes with a US quality stainless straight (not tapered) spokes – the difference between Asian and US stainless is tremendous.

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?

Disk brakes put a lot of stress on spokes, addition of engine doubles the stress, maintenance might get expensive.
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. Installation instructions on the ‘How To’ page of this website are very helpful in answering this issue.

Can I mount an Eagle bike engine top my mono-shock bike?

Yes, again, the installation instructions are helpful. The front mount strap is attached to the fender bolt hole (not the seat post), the securely mounted engine moves with the wheel.

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 bike motor?

The Golden Eagle standard kit comes with a simple kill button you can 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 a motorized bicycle?

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

Can I add an additional muffler to reduce noise of my bicycle engine kit?

No, unless it’s approved specifically for that engine, we do not recommend additional mufflers or silencers. Restricting exhaust flow can cause engine to overheat, reducing life and/or loss of performance. Warranty does not cover use of any unauthorized parts. An exhaust tip that turns noise away from rider’s ear, back and toward the street – makes a difference without causing air restriction, overheating or loss of performance.

Do you recommend a particular kind of bicycle to use with your Kit?

Click Here for how to pick the right bike for your Golden Eagle Bicycle Engine Kit.

What are the differences between a 2 stroke and a 4 stroke bicycle engine?

Click Here for detailed explanation between these two different types of engines.

Do you offer a warranty or return policy?

Yes, we offer a 1 year mount warranty and a return policy.

What kind/size of wheel does the drive ring fit?

Our drive rings fit either 32 spoke or 36 spoke wheels (recommended), requires the standard 3 cross or 4 cross spoke pattern, common to most bicycles. Fits 24″, 26″ and 700c (not recommended) wheels.
To provide the most dependable ride and simplify installation and least expense, we recommend: 26″ – 36 spoke wheels (stainless steel, straight spokes preferred), dual rim brakes, solid axle w/nuts on the rear wheel and a bike that is comfortable. The shorter spokes on a 24″ wheel are stronger than larger wheels (4x spoke pattern is perfect drive ring fit), the smaller wheel lends more low-end torque. A 26″ wheel allows faster top end speeds and is less expensive for tires (more common).

Will your motorized bicycle engine kit work with 700c wheels?

The units will fit a 700c wheel. The spokes of a 700c are longer (less strong for motorizing) and because of the amount of room under our Lower Mount Strap (main engine support) you would be limited to tire selection, 700 x 32 would probably be the most aggressive tire you could use or tire would rub the bolts that connect the engine bracket to the Lower strap.

We have quite a few customers that have made it work great with 700c wheels.

Will your bicycle motor kit work with 29 inch wheels?


How do I determine what size my wheel is?

Refer to sidewall of tire to determine wheel size, numbers indicate size of wheel and width of tire.
