URBAN TRASH CANS

If you mean urban bins you can realistically tip onto a hand truck, I’d go with a compact, rigid, rectangular wheelie bin—usually around 120L to 240L—with a flat back, a molded top handle, and two fixed rear wheels. Those are the easiest because the flat back sits neatly against the hand truck frame, the handle gives you a natural grip, and the square footprint stays stable when you tilt it back. Many municipal street bins in heavy plastic or powder-coated metal are also good, as long as they have a flat rear face and side grips. Round drum-style bins, very tall 360L-plus carts, and four-wheel dumpsters are usually much more awkward: they can be too wide, too top-heavy, or hard to balance on the dolly. If the bin is overfilled or the lid is loose, even a good one becomes annoying, so secure the lid and keep the load centered. In practice, empty or partly full 120–240L rectangular trash bins are the sweet spot: easy to tilt, easy to strap, and easy to move over curbs with a hand truck. If the bin already rolls well on flat ground, you may not need a hand truck at all, but for curbs, stairs, or moving several bins at once, a flat-back rectangular bin is still the most forgiving choice.
