Hi, I think this is my first post in the forum.
I am making a minibike from scratch, it is one of the things i wanted to do since i was a little kid, and now with better skills, some experience and some money, the idea came back.
I started like four months ago, but for money reasons, i had stop the project for like three months. Now with some money in my pocket, and a Bike meeting in my town in the next week, I want to finish it.
This is what i got so far, it's not so much. There was like 20 hours inverted, along various days (i could not use my dad's workshop too much because there are people working there all day, i have to work at dawn most the time).
So, here are the pics (they are out of date, i had sell my only camera):
The motor is a Two-Stroke Zanella (National brand) from my old moped, 70cc, 6000~7000rpm, tiny but very powerful, The moped developed like 80Km/h with that. (Another project, a three-wheeler with a same motor, but teaked, developed 105Km/h :scared: )
The carburator is a Dellorto 12-14 with a 65cal chicleur.
I am now doing the "thing" that holds the motor to the frame.
Something i cannot figure out, is how the heck I would stop the thing. At first I had the idea of using a disc brake, but i now realize that the disc would fits, the caliper wouldn't.
A drum brake would never, in the great history of earth, fit inside that little wheel, at least not one that i can find in a store here, i would have to do it, but then finding brake shoes for that diameter would be impossible for me.
The only thing that seems doable for me, is, using a transmission in two steps, like this bike http://img529.imageshack.us/img529/8949/img4438p.jpg
And using a disc brake in the transmission. But then i would stress too much the chain, do I?
PS: This are the wheels i'am using (26cm diameter, like 10 inches)
And the shock absorbers:
Well, I think that's all for now. Suggestions and critics are, off course, welcome.
Note: Sorry for my bad english, it isn't my native language, I'm from Argentina.
