Yes just search for "Adult Trike" in the website seach box.

I had it ordered to our local Wal-Mart, for no shipping charge. They also assembled it at no charge.

About 300lbs or more.

This model does not come in Green last I looked. Check by searching this site with keywords "Adult Trike" they may have another kind that comes in green.

No they do not have a 3speed option for this model. They do offer a 20" Trifecto folding adult tricycle with a 3speed.

base is 18 1/2"W x 14 1/2"D
top is 22 1/2"W x 19"D
back of basket has pins on each side that allow back side to fold down.

I do believe it is 300lbs, but I have seen two people (not suggested) ride one at the same time total weight approximately 450lbs +! Hope this helps.

You probably could as long as the hitch connector attaches to the the rear wheel bolt. To be sure I would asked a Walmart Associate to look at the specs on the hitch connector, bolt size and clearance of the tow bar.

if you buy it from walmart , it only comes in blue. but they have a black cherry on other sites.

I know that you will be able to ride with other young adults cause I do. On black top you will have no problem at all it will just glide along for you....cause I ride in a dirt road atmosphere and can ride at a good speed........I am approxiamately same weight as you as well, and I have not issues with that.......also, I exercise my dog, and she pulls me so fast on it, we fly!
I think you will be quite satisfied with the speed you can pedal with it. Have fun!
