I have fuzzy images of some of the duna parts and vary little information.but I think the car originaly had a 3.00x19"tire,when I got it last year it came with a jawa wheel,maybe from a velorex.this was 3.50x16",just did not look right.I converted the bearings on an old CL350 wheel that I had and this looked and fit much better.I finaly convinced myself that the car is so light that I do not need a brake.the honda wheel is rusted junk so I am looking for something maybe from a velorex but not sure if 19" is avalable.axle is 20mm changing to this size is easy duty.has someone got a good picture of an old duna.John
Maybe these links will help. You can also go to google.com and type in 'Duna Sidecars'.

The new Velorex Wheels are still 16" and handle tires from 3.50" up to 130x90. They now use a 20mm axle.
They are pricey, starting at $271.00.
