The squeeze hits high-utilization riders first, where small per\u2011km swings quickly turn into churn, incentives, and thinner margins.<\/p>\n\n\n\n<p>To put a number on that operational pressure, treat 2026 as a stress-test scenario (not a macro forecast): fuel prices step up ~30\u201332% year-over-year.<\/p>\n\n\n\n<p>On April 1, 2026, Reuters described a \u201cfuel crisis\u201d driving a surge in EV interest across Asia-Pacific (via <a target=\"_blank\" rel=\"noopener noreferrer nofollow\" class=\"link\" href=\"https:\/\/www.tradingview.com\/news\/reuters.com,2026:newsml_L4N40F05B:0-fuel-crisis-powers-surge-in-ev-interest-in-asia-pacific-region\/\"><strong>TradingView\u2019s mirror of the Reuters report<\/strong><\/a>).

Adoption still varies by country depending on swapping\/charging coverage, policy choices, and rider behavior.<\/p>\n\n\n\n<p>That first-wave story is mostly about averages: cost per kilometer, headline range, and rollout speed. The second-wave story is about variance\u2014and whether your battery and station system stays predictable at scale.<\/p>\n\n\n\n<p>But the bigger question is what happens after the first wave of rollout.
