Wide Wheelchair & Bike Rims for Dust

Postby gyre » Sun Aug 24, 2008 11:59 am

These started out for sand and were adapted for snow.
I rode some last year and I could go right across a dust drift barely slowing down.
I was told it was a snow bike.
The tires were very smooth with a chevron pattern.

Wheelchair Wheels for Sand

I don't know if these are the same tires, but the Remolino sure seem to be.

Remolino 80 mm Aluminum Rims: Originally made for sand riding in the Southwest and Mexico, these rims are unfortunately no longer made but these are the rims that started it all. Circa 1999, a creation of Ray Molina of Remolino Adventure Works in New Mexico, these rims were first made for riding sand dunes and soon after found their way to Alaska for snow riding. If you can get your hands on a pair somewhere, these rims and the 3.7 tires fit on the FatBike for a truly monstrous wheel set up.

Remolino/Tornel 3.5 Sand Tires: Made specifically for the Remolino 80mm aluminum rims shown above. Low profile high width with chevron treads for traction in super loose surfaces and punchy marginal riding conditions. Weight: 1320 g.

Surly Endomorph 3.7 Tires These are the biggest tires available for mountain bikes and work extremely well in a variety of conditions ranging from snow to sand to trails. The chevron pattern with side knobs roll surprisingly fast for such a huge tire. weight 1250 g.

Surly Large Marge Rims: 26 X 65mm double wall rims accommodate the big sneakers. Available in offset drilled version to fit the 18 mm offset rear stays of the FatBike or center drilled for the front wheel. Weight 1200g

I wanted to remind people of these after the dust this year.
It really does work.

The fish had inquired about playa worthy wheelchair wheels. I posted some links in that thread as to where I got the tires for my wheelchair. The ones I used for the quickie went right on without modifications to my chair. I can't find the vendor since my bookmarks are overloaded again and need to be sorted/archived. Maybe the fish will drop by the thread and post the links I gave her.

I can only do that by going through the threads again. Maybe if I search on wheelchair.

This is where I got the stuff for my wheelchair. I didn't have to use it much this year but I certainly wish I would have had it in 07 since I did wayy too much physical labor type stuff wayy too soon after gettin the foot run over.

Here's some back and forth between Fishy and Toolmaker about wheels. I couldn't remember how to bring you right to that post, but it's about 1/2 way down page:

I wonder how much trouble it would be to use a chainsaw or something for a cheap powered chair hack. Seen something along those lines used on trikes and got to thinkin that it might be nice to have a motor for dunes and long hauls. Those electrics just seem too heavy and a drag to keep charged compared to a hack using a gas motor that just needs some juice added here n there.

I found a website/forum that deals with powered bikes with all size engines.

http://www.motoredbikes.com

I would be interested in the weedwacker plans if you come across them.

i made a motorized ten-speed with a 49cc single stroke that was fun as shit (and slightly dangerous as it reached 40mph top end) and very easy to build by attaching second chain to front gear and utilizing back gears for torque, etc...

noisy little bugger though.

damn....it's snowing outside, and all i wanna do is ride.... :cry:

i think collectively, we could easily build and transport either a whole unit, or an adapter unit for the fish.

i agree, gas or propane is the way to go, electricity is still a little tweaky, but soon with the ever increasing power and duration lithium/ion batteries provide, i think this will change.

Jessica, I am an optical metrologist. A major part of my job is rapid prototyping so please shoot me an email and I can at least walk you through the steps you need to take.

I prefer working with prints but would be willing to put a prototype on the CMM for dimensioning. I don't know why any shop would tell you to get lost unless it was a production shop. You want to find a "job shop", something on the small and grimey side. Alot of the small shops are hurtin for work and will do anything. Also keep in mind some shops want 30-80 dollars an hour regardless of what they are doing. I'm in a gift giving mood today so to help you out I'll put up the CNC programming for free. Give me dimensions, material type, and what kind of CNC machine and I'll give ya the code.

surleybikes.com has wide wheels, and wide wheel bike frames. I've been looking at wheels for a trike design, but would need different kinds of hubs and a custom build... but still trolling ebay and other sites for that solution. the lowrider bike sites usually have a trike kit available and I've been looking into that for my chopper that I couldn't ride last year.

Money - Almost any machine shop will make what you wnat from whatever material you want. Some are more willing to work with you than others like any bisness.

Id call around or drop some sketches so we can point you in the right way.

The wide forks are available from Surly and will fit most bikes.
Other than frame modification, how about building a longtail kit to fit the wider tires?
Xtracycle has made the technology open source.

Xtracycle has a specific philosophy about the future of bike's evolution.
It would be easy to dismiss if they hadn't put their longtail innovation on the table.
It's a big site and I suggest looking around a bit.
Find out if the longtail might be useful to you.

If there is loose dust this year, wider and smoother is better.
You want to float over the dust.

I have been hearing from numerous local sources as to the lack of hydration in the region. Expect it to be dusty, just heard this past week from 2 sources that they seem to have skipped a season and went straight to hot as fuck summer season.

Its gonna be a pain in the ass for anyone trying to use wheels without motors.

I'll be riding a Surly Pugsley at the burn this year. The fat tires let you ride through soft stuff easily and also add some suspension even over the rough/hardpacked sections.

Very clever to use them for a wheel chair - I hadn't thought of that. *two thumbs up*

As has been noted above you can get the tires and rims from Surly Bikes, but they won't work in most bike frames due to a lack of clearance.

Wheelchair wheels have a few difference from bicycles. The hub is going to be different, whether the wheels pop off or not. I'm not sure what the adaption would be. I don't think that there's much experiementing, I think the wheels are much more expensive for the chair. Also, there's the handle that you grab to rotate the wheel so you can move forward.

It's actually a source of frustration to me. Wheelchairs shouldn't be as expensive as they are, because some componants could overlap wiht the bike market and achieve that sort of economy of scale.
