Built for: Playful, lightweight, and non-threatening in character, with automatic CVT transmission making it especially approachable and simple to ride.
Not ideal for: This is not for anyone wanting real speed, highway capability, genuine off-road performance, or a bike that can comfortably carry a passenger or luggage.
