You guys need to chill.

I've deleted some posts. Keep it up and I'll start swinging the velvet hammer.

looks like i missed some good fun last nite, maybe it is time for me to change-up my visiting hours here? anyway, don't want carleton swinging his velvet hammer so am keeping it chill, but...
i live in so fla too & ride my fg bike, which is set-up at the moment with pretty big gearinches, all over dade, broward & pbc, & also ride it over every intracoastal causeway & bridge. the flat land here is one of the many pleasures in this locale (don't need no stinkin gears here :thumb:) yet i go out of my way to ride over those bridges just to feel like i can still get up a hill.
why are you riding singlespeed?
unless you are a hard-core roadie or you haul a ton of crap with you, if you think you need more than 1 gear to ride around miami...you really need to just get yourself some kind of multi-gear bike & stop looking for inefficient ways to graft more gears onto your ss bike.
op has a bit of an excuse, stated he is in a hilly area. but i still wonder why is he so hot for a fg/ss bike if he can't get around his town on 1 gear?

One method, constantly overlooked, is a Schumplf internal 2-speed drive. http://www.schlumpf.ch/hp/schlumpf/f...riebe.engl.htm

"The Schlumpf drive is an ultra thin planetary gearing system located at the right end of the bottom bracket, between bottom bracket and right crankarm.

Installation of a Schlumpf drive hardly changes neither position of the chain nor position of the crankarms.

To activate a Schlumpf drive, there is no need for cables, derailleurs and the like.
Gears are changed by a simple push on a button, located at the end of the axle.

Push on the right side to shift up or down (depending which drive you use), push on the left side to shift back into direct drive."

cough road bike cough

2 cogs
 

So tell me oh great one
 

how does someone come in here and alter comments? My comment was altered, edited, whatever, into some s---ss remark. Does the system allow anyone to edit a comment and repost it?

Thanks Soil_Sampler...I like that better than my original idea of a single cog and double crank. Looks good. How does one change the gears? Is there still a rear derailleur or is it done manually?

I like it. Thanks. Looks like there are more options than I imagined there would be.

Pay attention to the text box when you "Reply With Quote" to a post. You can type anything in there:

It doesn't edit your original comment which is untouched earlier in the thread. Most of the time people take advantage of this in order to make jokes.

Jokes, huh? Okay, I lost my sense of humor somehere between multiple deployments and being back in the Pacific Northwest where it rains non-stop and we are lucky to get three consecutive months of dry weather cycling.

If only there was some kind of technology allowing an SS/FG rider to have a small cog on one side of the wheel and a large cog on the other, so that he can flip the wheel around for going up and down hills.

That is my favorite, as I do that pretty much every day I bike to the velodrome (track gearing is much different than street gearing).

Still, a road bike is the best option if you want to switch gears. You are definitely not going to run fixed gear and be able to change gears while riding (unless you have the internally geared hub above). Interesting options though.

Aaron, nice way to revive a bike!

double crank/dual cog
 

manually.

Sounds like you need...dun dun dun.. a velomobile! :-)

Where'd you get this bike computer? I've been looking all over for a Cateye in red:

not gonna read the rest of this thread.
just saying i saw a guy at hellyer on his tt converted bike, double crank front, one rear track cog. with an extra chain lengthed for the other ring ziptied to his seatstay. he says he switches between training on the hard ring for flats and training for spinning on hillies. just sayn again and again. JUST SAYING. STOP. coolstory.

That's a simple solution, but wouldn't the chain line be off on both rings?

Sure. Just like it's off in pretty much every gear you use on a road bike. It generally doesn't matter much, unless you're using a 1/8" chain and want a perfectly quiet bike.

And FWIW, something similar was being done in the late 19th century. But they used chains with manually detachable links so that they didn't have to carry around chain tools.

Speaking only for myself, by the time I'm changing chains during a ride, I'm just getting a derailleur.

manually changing gears by hand is a simple solution??

hahahahahahahahahahahahahahahahahahaha

seriously - single cog in front, single cog in rear, use a Schlumpf 2 speed drive inside the front crank, kick/tap the crank stem with your foot/heel when you want to change gears.

Now that is simple!

Thanks!!!!!!!!!
 

I did not realize there were so many options and drawbacks to what I thought would be a simple option. Everyone had great suggestions and I really appreciate it.

The Steintrike fairing is really interesting. I heard at a recent bike show in Portland that full bodied bikes are illegal here but I can't imagine why? Someone like the cops would mistake it for an unlicensed car driving in the bike lane? Yeh, maybe around here they would.

Really liked the photos showing exactly what would take a thousand words to explain. It is still raining here in the Pacific Northwest and could be for the next month and a half or two but that gives me time to try to put something together. Thanks again to all.

S3X is cheaper, and you get three ratios.

link please! got me curious. :)

Someone is pulling the wool over your eyes with their own ignorance or lack of the ability to *check the facts*. The ROAM cross-country velomobile tour last year *started* in Portland. The Left Coast Velomobile Gathering in 2010 was hosted in Portland.

Now, that said, they are illegal to drive on highways and roads not approved for cycling - but then again, that is true everywhere else in the world.

Good luck with your project! And let us know how it goes.

In fact I heard it from a vendor at the Portland Bike Show this year. The fabric fairings are legal to use as long as your head protrudes above the fairing like the Hase fairings but hard full bodied fairings are not legal.
