[FONT=Comic Sans MS, cursive]Hello,[/FONT]
[FONT=Comic Sans MS, cursive]Problems to choose, find, buy or build proper wheels for any of non-leaning light motorised vehicle were discussed on many forums and here at many threads... Maybe it would be useful to collect at one place many good ideas and solutions, and bad experiences too...[/FONT]
[FONT=Comic Sans MS, cursive]I do not have practical experiences with those issues, but collect and still collecting any information that I could find. I build simple HPV-qaudricycle for two of us (my wife and me), for cruising across and around Bern. Still have to finish and test it, so do not know if regular MTB 26“ wheels shall be good enough. If I have to reconstruct quadricycle and especially to change wheels – I shall need help to find simple and cheap solution.[/FONT]
[FONT=Comic Sans MS, cursive]As I could see on Internet, some people still use ordinary bicycle wheels on their 3-wheelers of 4-wheelers – but, only for HPV (no gasoline engines or electric motors). I do not know for their experiences...[/FONT]
[FONT=Comic Sans MS, cursive]Bicycle's wheels (MTB or BMX wheels) on any multi-wheel non-leaning vehicle (lighter the better), there is problems at corners and fast curves – torsional forces could be too strong. Could be said, with some irony, that issues are only with: axles, bearings, hubs, wire-spokes and rims! Tyres are relatively fat (wide and high) on relatively narrow rim - so, could be pulled aside at corners easily, if rim isn't broken before.[/FONT]
[FONT=Comic Sans MS, cursive]Axle: problem should be solved by attachment/support on both sides in bicycle's style![/FONT]
[FONT=Comic Sans MS, cursive]Bearings: maybe not a problem, even quite small, they are quite good for both radial and axial (side-way) forces on standard hubs (balls between tow cones); so-called cassette type (ball-bearings), are more sensitive under side-forces...[/FONT]
[FONT=Comic Sans MS, cursive]Wire-spokes: could be changed, but too complicated and expensive way (should be imported) and done by experienced persons (amateurs or professionals)...[/FONT]
[FONT=Comic Sans MS, cursive]Rims: could be reinforced by some metal rings? Or welded another rim on side, that could be used as band-brake, or for belt-power?[/FONT]
[FONT=Comic Sans MS, cursive]Special, stronger wheels for 3-wheelers could be bought here-and-there, but are quite expensive, and are not available everywhere. The same, there is possibilities to build wheels from special/stronger components, but... (always on BUT)[/FONT]
[FONT=Comic Sans MS, cursive]There are a few models of heavy duty bicycle wheels that could be bought in USA, but often need some modifications...[/FONT]
[FONT=Comic Sans MS, cursive]Moped wire-spoked wheels are stronger, mostly with drum of disk brakes, but probably too heavy for light vehicle. Most of them have axles of 12 mm, so have to be supported on both sides, as at bicycle or moped...[/FONT]
[FONT=Comic Sans MS, cursive]Some photos as illustration are attached (look to me as standard bicycle wheels used)...[/FONT]
