Sun Atlas Cargo Industrial Tricycle Review

Sun Atlas Cargo

Sun bicycles have been building quality adult tricycles for over forty years and has become the largest seller of adult tricycles in the world.  I personally know Jack and Ben, the owners at Sun Bicycles, and there are no harder working guys in the bike business.  Sun Bicycle’s philosophy has always been to offer good quality products at a low price and then stand behind the product.  The Sun Atlas is Sun’s most durable industrial tricycle.

Frame: The frame on the Sun Atlas Cargo is MIG welded together in Taiwan and has a 500 Lbs. capacity.  The frame is easily put together by bolting the rear section to the front by using four bolts.  The Atlas has a rear platform that bolts directly to the rear frame for carrying your cargo.

Gearing: The stock set up of the Sun Atlas Cargo is a one speed freewheel.  Most factory and industrial users will add the coaster brake kit to the trike so the trike can be stopped by pedaling a quarter turn backwards with the pedals. Sun also offers a three speed and five speed coaster brake kit which is a nice addition if you have to ride up a ramp or hill.

Braking: The Sun Atlas Cargo uses a “V” style front brake which is welded to the fork of the trike.  The “V” brake comes with oversize brake pads and can stop the trike more than sufficiently.  The rear brake is a band brake which has a disc on the rear axle and a band that squeezes down on the disc when you wish to stop.  Band brakes are very popular in Asia and third world countries because of there simplicity and reliability.

Seat: Big, oversize and with springs, all of our trike testers feel that the stock seat is of good quality and more than comfortable enough.

Ride: We like the ride on the Sun trikes.  The cranks are positioned a bit farther forward and gives the Atlas Cargo a more recreational feel and adds stability.  While moving the cranks farther forward helps stability, it also make riding the trike standing a bit more awkward.  The Atlas Cargo handing is precise and predictable and all of our testers thought Sun has offered up a good designed product.

Wheels:  Sun offers only one wheel set for the Atlas Cargo and it is a steel set of wheels with extra thick spokes.

Other Stuff: Large rear platform, front fender and reflector set are included.

Pros: The Atlas Cargo brings safety, durability and stability to everyone who rides this well built trike.  Features sealed crank, headset and rear axle bearings, extra wide saddle with springs, heavy duty platform  The frame is MIG welded together and the construction is solid.  The paint is applied evenly and consistently and should last for the life of the trike.

Cons: You have got to like safety yellow or you are out of luck.
