I feel like the benefits of belts are marginal at best, if you do t want to buy an expensive belt drive bike and drivetrain, chains are better from the stance of low cost for your complete setup.
@Prontomomo@mettwurstkaninchen I find most of the "problems with chains" that belts purport to solve are problems with derailleurs, not chains. Get a hub gear if that's a problem. Doesn't have to be a belt drive one.
