Default Re: WHEELS for velocars, velomobiles and other multi-wheelers

Scott @ Silver State has some nice 21" DOT wheels with brakes in stock, I picked up a pair for a project:





Mounted a set of Avon Speedmaster 3.00 x 21 tires. Should have a nice ride.

Would make a good wheel on a velocar with an 80/90-21 tire mounted. Good sized brake, 9 gauge spokes, aluminum rim.

I still think about using my MTB 26 wheels with some modifications if necessary: to make them stronger and more resistant to side forces (anti-twisting reinforcements). Maybe to make additional flanges that will add new support to rims (by spokes)? Maybe to add new rim, that could be used for belt-transmission (or outside belt-brake) with reinforcements to regular rim and connection to original or additional and bigger flanges... Maybe to install plywood-disk, as one Russian guy did... Still, just winter-thinking...

Ciao, Zoran
Yes Zoran i think the second rim like that would add strength.The first 2 pictures ..........Curt

.. if we could have that, such discussion should be finished!
Great wheels indeed. If somebody wanted veteran car look, then for front wheels could use moped's 18" wheels, as I could buy in Belgrade. Not an easy job to bring four of them here to Bern!
Maybe all that should be to heavy for pedal-powered quadricycle with small electric-motor or gasoline engine (as assistance)..
But, I will like to have them! (easier to change plans than to make own wheels for old plans)
Thank you,
Zoran

... which is diemension of axle?
TOMOS has 12 mm axle (less then 1/2") which isn't enugh for supporting them just on one side, but demends support on both sides as on moped.

Where I could find more details and prices for your wheels?

FFV8 Yes they are nice and would make a good wheel for volocar.

Also was looking at west coast chopper wheels today and they have a really wide hub that would make a good hub for the taller wheels...............Curt

Those look like really nice wheels... and 9 gauge spokes... wow!

The Tomos wheels have bearings, what about removing the one that goes on the inside face of the wheel and replacing with one that has a bigger internal diameter? The axle then only needs to be a stepped design, not a taper.

Hello Ludwig,
That is one of the solutions, without too much machine-tooling work on hubs. Just to find exact outside diameter of original ball-bearings. In Serbia, I found company who sells good quality (mostly SKF and other German), with huge inside diameter, I think more 20-25 mm. Maybe to change both bearings and made new axle according to their inside diameter dimension, without step? I am not sure if such bearings are strong enough: must have smaller balls and thinner rings?


Could needle bearings be useful? Maybe not resistant on side-forces...


Ciao,
Zoran

Rollers, perhaps tapered rollers. We had to open out a wheel once at a race meeting, the only bearing we could find to replace one that collapsed was a bigger o.d. So we took a drill with a grinding bit in it, put the wheel on a spindle taped to a chair, and kept turning the wheel and grinding it out until the bearing fitted. It was a long night.

It's too bad that their website doesn't list too much, or have much info on what they do have listed.
