hi, i have a new three wheel bike that i will be touring around the west coast and i would like to covert it to a 3 seed bike. does anyone have any ideals or web sites with the info needed for me to do this myself? i have built my own trailer and need the gears to go up hills and over the long roads from Yuma, AZ to Seattle, WA. speed in not the issue, load is the problem.
Hi JT;
On bike it is trivial conversion; on the two rear wheel trike, it maybe a significant challenge.
We need a side view to start, and probably some close ups around the rear sprocket.

retro fitting will be the issue but there are many company's that sell similar hubs

[attachment=3922][attachment=3921]thank you very much . i will have my hands full doing this, here are a few shots of close ups
Hi Joseph;
Your pictures are excellent.
It looks like you can move the sprocket on the axle side to side; which will probably be required.
You have a drum brake; you should get an IGH (Internal Geared Hub) with a drum brake - Sturmey-Archer and Shimano both have these.
The IGH you get also needs to have a really long axle. On the third picture down, measure the distance over the outer most nuts - this is the MINIMUM axle length you need; longer is okay. On the same picture, measure the inside distance between the frame pieces at the point your current transfer hub bolts on - this is the OLD (over lock nut dimension). The hub you get must have an OLD that is no more than 2½mm more than your measurement. It can be less than what you measure because you can add washers.
You will probably have to alter the overall gearing after getting your drivetrain built up and tested. The easiest method is to change the chain ring on the crank (may require a different crankset).

There is also this way I found interesting. There is also a replaceable hub that someone offers for sale about a 100.00 USD or so. I will try to find the link, but for now there is this article...

Good maintenance to your Bike, can make it like the wheels are, true and smooth!

[[Hello , this is good info for me as well. Glad I found this thread. I was looking on Amazon for 3 speed internal hubs and found some. When I clicked on the reviews and details for those , they said it didn't work on the Schwinn meriden because the axle is to short because on the Schwinn it is used to attach the frame together as well. I'm going to sift through the information from you and Bill and see what I can figure out. Also I'm going to see if there is any instructions on taking the rear cog off. Haven't had any luck searching the web.For my application I'm trying to get more top end and just adding a 3 speed probably wouldn't accomplish this unless I changed the gearing. This would then add a couple extra gears anyway. Hope it is allowed to reply in the middle of this thread, cause I don't want to be rude. I will follow this thread and try to figure out what to do for my problem. I left you a message after you sent me information on the gear ring and cog options. Thanks

whats the model no of this bike, and does it supply power to both wheels or just one wheel. thanks.
I don't want to discourage you but I don't believe there is a route between those two end points that does not include mountains, not just hills. Most cyclists would be challenged just getting a loaded bicycle over the approximately 30,000 vertical feet of climbing that would be involved, let alone on a 3 wheeled bike with probably 100+ lbs of equipment and trailer.
