jackshaft from coaster hub?

Help Support Rat Rod Bikes Bicycle Forum:
I have seen it done. My main concern with the idea is when people use it for the braking too, yes normally there is a load through the chain on a coaster brake, but nothing compared to the load the rear chain would experience with the brake at the jackshaft.

I have a worksman porta trike. It has a three speed hub with two sprockets on it, one linked to the chain ring the other linked to a coaster brake hub.
I'm wanting to do something like that, but without the three speed.

Is the brake going to be used? And yeah, a lot of trikes are set up that way, plus you can buy cb hubs already set up like that. http://www.huskybicycles.com/mm5/merchant.mvc?Store_Code=hb&Screen=PROD&Product_Code=362-510
The brake will be used, but not in a hardcore skid Mark stop kind of way.
My plan is for a cruiser that I'll just cruise the local bike path with. (Not many hills around here either).
That link looks like just what I need. Thanks.
Good to know that trikes are set up that way, it must work ok then!

I also have a trike, a Torker TriStar, that came with a three-speed coaster brake hub, with a second chain to the rear axle. I've since converted to a five speed Sturmey Archer set up the same way.
I'm actually thinking about doing something like that when I build myself a bike with REALLY wide tires, just to shift the chain line out enough to clear.

My worksman trike has a three speed coaster set up like that. Its the reason I asked the question, I figured if it could be done with a three speed, then why not a single speed?
Yep, they exist. I bought a 5-speed coaster brake trike hub for my trike from niagra cycle (dot com).
The hub you want is called the TS-RC5. You'll need to mount it on a rear end wide enough to accept a 127mm OLD hub. I've seen these sold as "Sun" but the hub itself will be marked Sturmey-Archer.
Sure, but depending on your trike, it's gotta be mounted SOMEwhere; some prebuilt trikes have 110 or 116mm between the mounts for the diff/jackshaft. Others are wider, or adjustable. I know tht the trikes i've worked on most, the Worksman Port-oTrike, they'd have trouble accepting that hub without modification.
I think that works pretty well, so long as you're thorough in the thought process. Are you building a trike, or do you wanna use a jackshaft for some sort of elaborate drivetrain on a 2 wheeler?
PS- If you want to get really weird with it, the hubs marked "QS-RC5" also have a reverse gear....
