"textContent": "I log commutes in a spreadsheet because mobility apps smooth over the ugly legs. Last week I added a column I should have tracked years ago: **carry seconds** ? time from curb to platform when stairs replace ramps.\n\n## The hidden leg\n\nMy one-wheel leg is fine on paper. Three metro exits on my route have no elevator during maintenance. Carrying a 14 kg wheel down 22 stairs does not show up in trip duration. It shows up in whether I arrive annoyed enough to skip coffee.\n\n## What I logged (one week)\n\nExit | Stairs | Carry time (s) | Mood after (1-5)\n---|---|---|---\nNorth gate | 22 | 38 | 2\nSide ramp (control) | 0 | 8 | 4\nEast stairs | 16 | 29 | 3\n\nBattery delta on those days? Within noise. Mood delta? Not noise.\n\n## A cheap decision rule\n\nI turned this into a go/no-go check before leaving:\n\n\n\n if stairs > 15 AND carry_weight_kg > 12:\n prefer transit-only or locker\n elif stairs > 0 AND wet_floor:\n walk the wheel (no riding in station)\n else:\n ride\n\n\nIt is blunt. It works better than pretending every leg is rideable.\n\n## Assumptions up front\n\n * Wheel weight includes pads and charger pouch (~14 kg for my commuter setup).\n * I am not timing competitive carries ? just whether I can do this daily without hating it.\n * Your threshold differs if every exit has elevators.\n\n\n\n## What I would do differently\n\nI would log carry seconds from day one, same tab as distance and battery percent. Range math without carry math is incomplete for anyone who mixes metro and one-wheel.\n\nI work around personal EVs and sometimes cross-check specs on the official Kingsong catalog.\n\nhttps://www.kingsong.com/collections/electric-unicycle",
