Greetings and salutaions to all, I would like to get some opinions and ideas for wheel sizes and hub widths as well as spoke count for a tadpole trike. I would like to build a modified Streetfox, without rear suspension, but with the back half of an old mountain bike. I need to overcome a few obsticales (literaly), 1-need to handle up to 500lbs (prefer it overbuilt), 2-be able to slowly go over curbs, 3-seat height between 14 to 18 inches. I was thinking about 26 inch wheels all the way around, I don't want fat tires, but between a 26x2-2.4, maybe 24 inch front wheels. I would go with 20 inch in the front but I'm worried about getting hung up on a curb. I'm guessing running 36 or 48 spoke hubs, didn't there use to be some 26 or 700C rims for tandems that were 48 spoke? Would a better idea be to make some custom passthru hubs for thicker axles in the front? would making the hubs wider or narrower for more or less spoke lean help with the lateral forces? Maybe use motorcycle front hubs for a thicker axle and still have a disk brake, could a bicycle wheel even be redrilled for stronger motorcycle spokes? I'm not as concered about weight of the trike as it being able to fit my needs as gearing can always be changed to help with weight. I also know the seat height will be less stable, the only limit to width would be to fit through a 36 inch door, I also don't mind less of a turning radius for running taller wheels for ground clearance. I hope this will spark some great ideas and that I posted this in the right place.
