retro direct

i don't know how "alt" it is but i built a retro direct bike today. i was really surprised how quick it went together and how many simple it was to build. i recamend every one build one of these bikes all you need is two freewheels an old jockey wheel a bottom bracket cup and some extra chain. a little know how and some creativity to mount the jockey wheel on the chain stay and your pedaling backward and moving forwards.

I'm not that computer savvy. Every time I try to put a picture up on this site it comes out as a box w/ an x in it. Any idea how I get my picture to have a url?

Post your photos on photobucket.
Then on the photobucket index page, see where it says "IMG Code". Click on that. It'll say "copied" then.
Then paste it here. Then it looks like this:

If you have several pictures, open up Notepad first, paste the "IMG Code" there, add text, then paste the whole thing at once.

No photobucket, go imageshack, that way you don't need to register, and they still give you a link.

photobucket won't let me upload my Pics (I hate computers) onto there site. It keeps coming up error. I'll keep trying but in mean time you'll have to take my word for it. My next step is going to be putting a rear derailer on the chain stay to regulate chain tension. It should be pretty reliable after I do that. Again sorry no pics yet

how's the second freewheel on there? are they special skinny freewheels or something? are the threads on a hub long enough to fit two?

that looks awesome.

the threads on a freewheel hub are the same as a bottom bracket cup, so all you need to do is install the bb cup in to the first freewheel (you may have to leave the first freewheel threaded out a little or use a spacer) then screw the second freewheel on. My next step is going to be mounting a rear derailer on the chain stay to regulate chain tension. It should be pretty reliable after I do that. right now its only safe to pedal backwards. to much torque pedaling forwards pops the chain off the forward drive freewheel. as you can see my prototype bracket is kinda flimsy. And i want to get a larger freewheel for my low gear.

Very neat.
How did you attach the BB cup to the first freewheel?

Do you think it would make a difference if the inner cog lined up with the top of the chainring instead of the outer cog?

Is the only advantage of a retro direct setup the ability to spin the pedals forward and backwards? The first time I saw a guy rigging a bike with this set-up, he was using two rear cogs of different sizes with the idea that the larger gear would make it easier to climb a hill when you pedaled backwards. I was all excited to figure out how to build one for myself and described it to a local bike mechanic who is quite a guru. He said that there was no "mechanical advantage" because you weren't using a derailleur to change gears. Therefore, the one chain is spinning through around the front gear and both back gearsno matter what what way you crank the pedals. Hence, it's an illusion of you think you're changing the gear ratio. Thoughts?

I think you'd have two gears, but I don't think you'd be able to put out as much power pedaling in reverse... so it's not going to help much in the end. I still would like to take one out for a ride though! Besides, pedaling backwards and moving forward is sure to turn some heads.

I'm not seeing why the chain sitting on the forward cog would mess with the mechanical advantage of the larger rear cog, since it's not actually engaged when the rear cog is in use, it's just freewheeling. Obviously running the chain over so much stuff will add some friction compared with simpler drivetrains, but it doesn't seem like the mechanical advantage would be compromised.

especially if you do like when you were a kid and sat on the handlebars, so you'd still be pedaling forward. if anyone saw you you could complain about your dagnabbed walmart bike.
