Rider Profile

Best For	Note: capacity is listed as 139cc but the model name and top speed of 45 km/h strongly suggest this is actually a restricted 50cc moped-class scooter, so figures should be read with caution; this machine suits complete beginners or those wanting a low-sta
Purpose	It's built purely for short, slow errands and getting around town at moped-legal speeds rather than any kind of performance riding.
Rider Fit	Its very light weight and small 10-inch wheels make it easy for almost any size or strength of rider to handle and manage at a stop.
Character	It has a friendly, unintimidating, utilitarian personality suited to relaxed, unhurried commuting.
Not Ideal For	It is not suitable for highway travel, touring, carrying a passenger any real distance, or riders seeking excitement or speed.
