>>413312>I probably could go by with just a regular bike with a sidecar then, couldn't I?Nope. Ural and Royal Enfield are the only companies that make sidecar motorcycles. I've heard that Ural's quality has improved by leaps and bounds in the past decade. I don't know anything about Royal Enfield other than they're made in India.
There are one or two companies that make custom sidecars, but they are pricey just like Urals. Nowadays if you say you want a "3-wheeled motorcycle with decent cargo capacity" you'll end up with this pic.
