ALERT NEW QUESTION

I have been thinking about this new bike building contest. I think I might do a mountain bike after all. If I do I could care less about the gears and stuff. So I'm thinking I'll toss the derailer or whatever its called. and go one speed. Just cut the chain down to length but, which of the rear gears will be the one inline with the crank best. Surely one of you geniuses has done this successfully. My try with the Huge Mountain Bike showed me it would work but I never did get the gears lined up right. At least I don't think i did.

So help a po boy out, if you can.

DON'T DO IT!!! Well at least don't lose the gearing!! A budy and I are soon to release a jack shaft setup with freewheel crank. So you will have full gear ranges. Imagine, starting off with just the clutch, going up big hills, dirt biking. Get rid of the spoke driving sprocket.

I will post images, and info soon. We will be selling the set up as a kit. Of course the most expensive part is the freewheel crank.

sounds great but here you have to have pedals to avoid the motorcycle laws. Those are quite stringent for inspections and licensing and insurance. Maybe keep the pedals on the crank. Actually i think there is a prohibition against gears. If it has gears it is a motorcycle I think. Heck i don't know for sure.

You will still have fully functioning pedals.

Deacon-

If you do like I did (non-motorized bike) the gears line up in one gear, dependent on the bike....I think it ended up pretty close to what a one speed bike would be.

I was trying to help out a local low income kid, so I took one from the junk heap and the derailuer was rusted, so I removed it and cut the chain down. He was happy to have a one speed, and it only cost me a couple of tubes, a seat and some time.

When I did do that with the giant mountain bike, the darn thing kept jumping the sprocket. I think i really had it on the wrong sprocket. If I go with a mtb for the build I'm for sure going to go at least one speed, if not put a cruiser wheel on the back.

I think you can adjust the back derailleur for about any gear you want on the back there is 2 screws to play with but I'm not the rocket scientist on this. You got time so you can play with it looks like you got another project in the makings.

yes im already thinking about the bike building contest. It all depends on whats available at the time I decide to start on it. But it's always nice to have some idea in advance the easy way. Of course I will figure it out. Hows the job going?
