Ahhhh rijopiatt, first let me say "Welcome to the wonderful world of Motor Bicycling"!
Now, sit right down here, and help yourself to some free BubbleUp, and some Rainbow Pie! Ok, down to business while you enjoy your free refreshments........200.00 budget and 40mph is the goal?
IF I got
an engine free
spent 50.00 on centrifugal clutch
25.00 on rag joint and sprocket
50.00 on peanut tank with cap, petcock, fuel line and filter
25.00 on throttle handle with cable
19.00 on #41 chain (TSC corp)
Hoot mount about 25.00, Grube mount is 50.00, but nicer
we are now at 194.00 not including shipping at 8.00 to 10.00 per item!
And the bike will not pull itself because there is no ratio-reduction inline so that the engine will have enough torque to turn the large diameter of a bicycle wheel.
Can I refill that Free Bubble-up?
On a serious note, it would not be possible for me to pull in a bunch of favors, scrounge and save money on every part, and accomplish the 200.00 budget.
(yes I have enough stuff around here that I could build several without spending any more money, but I'm a 4-stroke guy.)
A friend got a 2hp Briggs free, used a Whizzer drive ring (65.00 + 15 shipping) long rear belt (25.00), a free bike, spent 25.00 on good paint, bought a 65.00 +10.00 shipping front half of a cvt, seat was 25.00, 10.00 idler pulley, made a bunch of parts, had free machine shop at disposal, and it does run, but the ratios are wrong. I do not know what else he may have spent, but I do know I don't have free machine shop time and materials! "Rocket Man" is now at 220.00 in addition of any expenses I was not aware of.
40 MPH is not legal in motor bicycles, and actually not really easy to accomplish either. 30-35 is much more realistic.
Let all of us know what you think?
(below are a 3 of my bikes)
