Best for
Built specifically for technical trials riding and obstacle navigation rather than speed, distance, or road use.
Built for
A pure, minimalist trials tool that thrives on razor-sharp low-speed agility, tractable low-end power delivery, and total rider control over the bike's balance.
Not ideal for
Not for riders wanting highway speed, passenger carrying, long-distance comfort, or any kind of touring capability.

Scores are derived from the spec sheet using the same model across every bike, so they compare like for like.
