realistic gas mileage

Howdy. Aside from my intro this is my first post. I have two golden eagle powered bikes. Golde eagle claims up to 250mpg or 30 to 35 miles per tank. I have the 26 and the 40 Tanaka pure fire Engines. The 26 has a 22oz tank. Assuming that I get 35 miles per tank I would have to burn 7.14 tanks to go 250 miles . Thats over a gallon. My realistic mileage is about 22 miles per the 22oz tank. I'm still happy with my 127 mpg that i get. What are you getting :cool:

250 mpg, but my riding conditions are atypical. Straight down 2000 ft. & back up. On the down the engine is off. On the up I'm pedal assisting vigorously, in order to keep the bike rolling forward.

Dimension Edge
700cc wheel
1 inch roller friction drive
49cc Tecumseh
Hard 3/4 to full throttle
120 to 130mpg
Cruising 1/4 to 1/2 throttle
160+
One tank full over 50 miles on 22 oz of fuel (not typical)
I figure 128 mpg or one ounce to the mile for carrying fuel.
Flat to rolling terrain paved roads.
Going to the largest roller should increase the MPG and top end at the expense of low end.

recumbentbill,

GEBE claims 200-220 for the Tanaka 26, and 140-160 for the 40cc. They only claim 250 for the KZ 25cc.

From the replies so far, the Tanakas appear to be thirsty beasts, regardless of displacement.

I hope we get more data.

It can be as much as they claim, it depends on riding conditions and how much the rider is helping the motor. On my upright bikes (cruisers/mountain), I get around 160 +. That is a lot of stop and go riding. On my prototype (stretch cruiser) I regularily get around 212 + up to as much as 238 (that's on the EHO35 engine).
