SELECT DRIVE RING SIZE:



EASY to start and QUIET! This Mini-4 is All Heart -
  • Low-end torque for easy take off and moderate hill climb - Easy to pedal, assist the engine when faster acceleration is desired
  • Slow speeds and Quiet running make this model an unexpected pleasure to glide thru the neighborhood or RV park on a quiet Sunday morning.

Reaches top speed of 26 MPH - Range of 30 miles per tank - Gets up to 225 MPG
  • Tests conducted under 'real world' conditions - with a 210 lb rider - steel frame 26" bike (add another 50 lbs for bike, engine and mount) using the Trail gear.
  • Mileage will vary with terrain, riding style, tire size & tread and weight load (as with autos).

Low-end torque and clutch engagement at lower rpm's result in a smooth, easy ride at slow speeds.
  • Very easy to pedal, to assist the engine when faster acceleration is desired i.e....taking off from a stop, after cornering or on inclines (when you can catch the pedals). Clutch offers little resistance, easy to pedal at slow speeds without the engine.
  • When engine use is Not desired, for long distance pedaling, flip tension lever arm to Off position, roll bike as you lift belt from track of drive ring and secure belt out of the way of any moving parts.i.e..wheel and spokes. It's just as easy to re-install the belt when engine use is again desired (though for the life of me, I can't imagine anyone Not wanting to use the engine!).
GEBE recommends two of our, easy to change drive gears for the 25cc - an allen wrench (5/32" or 4mm), our 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 the different gears, no additional adjustment is necessary.
*The Trail gear (included with kit) - great for street & off-road - moderate hills & trails.
*The Standard gear (sold separately) better on more level terrain for faster top end speed.
