Ultra Might Feel Like Too Much If…
✖ Who Ultra Is Not For
- ①You're mainly comparing Ebikes by upfront price, not total cost over time
- ②You focus on spec numbers more than how the Ebike performs day after day
- ③You expect range claims to matter only on paper, not in real use
- ④You believe more motors automatically mean better performance — You haven't realized that a well-designed single-motor setup can outperform expectations
- ⑤You might not realize how much freedom a bike with extra off-grid battery capacity can give
