Hello All,
Just wondering if anyone knows what material is common to bicycle wheels. These are the typcial utility style rims as found on sidewalk bikes, childrens bikes, and the low-end BMX style. Cost and toughness are primary considerations, so I was thinking maybe a toughened unfilled 6/6.
This particular application is low speed <10 rpm's, 12.5 x 1.75 nominal rim size, max loading in either static or dynamic will be about 250 lbs, and will operate slightly out of perpendicular to the floor (max 8 degrees). Tire selection will either be solid urethane (foamed center) or 58 psi max pneumatic tire/tube. Impact during usage will be nil, but should be able to withstand incidental impact of handling, loading in and out of vehicle, etc.
Any thoughts?
