I noticed that a lot of bicycles come with alloy rims. How strong are alloy rims when you have a 263 LB person riding on the bicycle? Especially the thinner alloy wheels that are on the comfort cruiser bikes like the Schwinn Willy 7 speed or the Raleigh Detour Deluxe 24 Speed? Do alloy rims get warped very easily or break when a 263 LB Clydesdale like me rides a bike that has alloy rims? When I ride my bike I ride it easy. I don't do any mountain biking or ride like a maniac. I would basically do "gentle" riding and "cruising".
Also, what other materials are bicycle rims made of which are stronger than alloy which can take the 263+ pounds of weight of a Clydesdale? I'm curious to find out how strong alloy rims are and how well they hold up with very heavy 263+ LB riders like me?
