2 STRIDA 5.0 in yellow, my favorite color. They fold down to a very compact 45” x 20” x 9” (114cm x 51cm x 23cm) and they weigh 22 lbs.
The drive train is a Kevlar Greaseless Belt Drive. No worries about chains and grease messing you up. And when put away in their carrying bags, they are easy to stow and equally easy to take ashore.
They are funky, have many optional accessories and have quite a following. They come with 16 inch wheels but an 18 inch kit is available at, what else, extra cost.
The real drawback is the price. Street price is about $800, each.
