Best for: Built as an electric sport-naked for punchy city and backroad riding rather than long-distance touring or off-road use.
Built for: Delivers immediate, linear electric acceleration and quiet, refined power that rewards smooth cornering lines over outright top-end drama.
Not ideal for: Not well suited to riders planning extended multi-day highway touring or any off-road adventure riding given its limited range and street-focused chassis.

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