How it rides
Editorial estimate from the spec sheet - not lab tested- Best for
- Built for urban commuting and errands with adventure-scooter styling; a practical, economical daily runabout with enough range for the odd longer hop.
- Built for
- A rugged-looking yet friendly small scooter: nimble, frugal and fuss-free, dressing city-scooter practicality in adventure clothing without real off-road intent.
- Not ideal for
- Not for highway cruisers, sport riders or those wanting genuine off-road ability; 12hp and 13-inch road tyres limit outright speed and rough-terrain use.
Scores are derived from the spec sheet using the same model across every bike, so they compare like for like.
