Tanaka PureFire


Purefire®, Tanaka's innovative two-stroke engine, is a traditional two-stroke engine that produces ultra-low emissions without the need for special or additional internal moving parts.

During the intake/compression stroke, the optimized scavenging system within the cylinder and crankcase walls (see illustration), significantly increase the atomization of the fuel/air mixture which results in a much more efficient combustion process.

Then, in the combustion/ exhaust stroke, the exhaust exits through a small catalytic converter in the muffler where the remaining hydrocarbons turn into carbon dioxide.

Years of searching for a 4-stroke engine that could compete with the Original 25.4cc two-stroke Golden Eagle Bicycle Engine - meeting it's High standards of Performance - Dependability - Fuel efficiency and Environmental friendliness - has met Successful conclusion.

** 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 can 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 frequently. 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 vary.

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

DO 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 want you to ride safe. Always wear your safety equipment!
Helmets are the law in most states, we also feel eye protection is a must.
  • Make sure your bike parts will be safe for the speeds you will be running.
  • Make sure your rear rim / wheel is true and there is no warp or wobble.
  • Give your bike a complete safety check.
  • Be sure all nuts and bolts are tight.
  • Check your brakes for wear and proper adjustment.
  • Check your tires.
  • Consult the manual that came with your bicycle for a complete safety and maintenance check.
  • Obey ALL traffic and speed laws, drive Respectfully & Courteously but Defensively.
  • Do Not ride faster than your field of vision - avoid potholes and debris to avoid accident or wheel damage.
  • Wear a good BMX type, full coverage helmet.
  • A Mirror is all but a necessity.
  • Front and Rear Fenders are more than convenient, keep road grime and debris out of your face and off your back.
  • After you have run a through a few gallons of gas, re-check and re-tighten any nuts, bolts and spokes - this is your transportation, perform maintenance routinely.

We do feel you should be warned! Don't over do it!

After riding for a couple of hours (40-60 miles), you wont feel as though you have exerted much energy because you have had such a blast - BUT - unless you are in excellent physical condition your muscles are going to feel it. Golden Eagle could be marketed as the ULTIMATE exer-cycle, but that was not our primary goal.

Our goal was to build the most dependable, affordable and practical mode of transportation available for everyone, young or old, the physically fit, or over weight and out of shape. The Eagle will carry you further, faster, and for fewer pennies than anything else on the market. No drivers license required in most states or countries. We do recommend that you check with your state and local ordinances - they all vary in top speeds and engine size for moped and bike classifications.

With our unique belt drive design we have created the ultimate in bicycle assist engine kits. You will not be limited by road conditions, weather, or the distance you need to travel.
