I have the air-cooled version of this moped and am highly impressed with its reliability and performance.
The Atlantis is a 50 cc two-stroke twist and go moped. Twist and go means that there are no clutch and no gears, so it is a doddle to ride as you just twist the handle and go.
The brakes are as on a conventional bicycles on the handlebars. There is disc brake to the front and drum to the rear wheel.
The 7.2 litre fuel tank, (1.6 gals) will take you about 100 miles which is a good mpg for a 50 cc two stroke.

Starting is either electric or kick-start and I have never had any bother starting mine. It's garaged at home but left out all night at work.

The instrument panel is basic but informative with oil and petrol level warning lights and an indicator repeater as well as the usual speedometer and odometer.

There is ample storage space under the locking seat to allow storage of a full faces helmet and gloves.
There is a shackle under the running boards to secure you moped to the immoveable object when parking.

Maintenance is scheduled at 1000, 3000, 6000, 10000 and thereafter. I have not yet had to have any unscheduled maintenance and have done some 16000 km or 10000miles so far in just 14 months.

Top speed is approx 55mph but top speed is reduced to about 40mph with wind against up hill.
Road tax is £15.00 and insurance is of course rider dependant but being a moped it is generally cheap.
This moped can be ridden indefinitely on a full UK car license.
All in all this is a good moped and reliable. It looks good and is very cheap to run.
