🤖 Electric bikes reshape cities
E-bikes extend the practical range of a bike ride enough to replace car trips, and are already changing European and Chinese cities — a major urban-transport shift.

⚖ Why this verdict
fully deterministic — evaluate.py replays this from daily closes; nothing below is editable or hand-set
- Window: 2021-07-16 → 2022-07-16 — first mention + 12-month horizon, then the window locks.
- The call: ▲ LONG NIU (primary play). NIU fell 74.4% over the window → direction-adjusted R = -74.4% (the call lost money).
- Benchmark: holding SPY over the same window returned -9.4% → α = -74.4 − (-9.4) = -64.9% — what this call made or lost against just owning the index. This is the number the verdict uses.
- Rule fired:
· HIT — R ≥ +10% AND α ≥ +5· PARTIAL — R ≥ +5% OR α ≥ 0▶ MISS — everything else
- Credit: supporters of a MISS earn 0 each, opposers the inverse — this feeds the scoreboard weights. supported: Jason

SUPPORT
“With these electric bikes, instead of going 10 miles on the way there, it takes your 10 mile ride and just puts you at 25, but you're still burning the same number of calories. It's like augmenting. I really think that electric bikes are going to change cities like in a major way. They're already starting to in Europe and in China.”
