How it rides
Editorial estimate from the spec sheet - not lab tested- Best for
- It's best suited to commuting, trail exploration, and general dual-sport fun rather than outright speed or long-distance touring.
- Built for
- It has the personality of a nimble, playful trail companion, happiest picking through tight streets or unpaved paths rather than chasing top speed.
- Not ideal for
- It's not for riders seeking high-speed highway cruising, heavy touring capability, or carrying a passenger in comfort.
Scores are derived from the spec sheet using the same model across every bike, so they compare like for like.
