Xootr (pronounced "zoo-ter") is a manufacturer of folding kick scooters and folding bicycles. Xootr scooters are characterized by 180 mm polyurethane wheels with aluminium hubs, and a hand brake for the front wheel (for the rear on old models). Compared to the other folding scooters with smaller wheels, these larger wheels provide an easier ride, at the expense of a somewhat less easy portability. The hinge is distinguished from competitors in being locked by inserting a pin, rather than by a cam or other latch. The platform is large enough for adults, and available in plywood, magnesium, or aluminum at different prices.
Xootr scooters were originally introduced in 1999 by Nova Cruz Products. Since 2003, the Xootr scooter has been manufactured and sold by Xootr LLC.
The earlier Nova Cruz Xootr was made with a plastic handle cap which is prone to breakage. This is part of the mechanism for clamping the T-Handle at the correct user height. The current version is aluminum and an upgrade kit is available, with downloadable instructions. See the Xootr website.
The Xootr Swift Folder folds more quickly, though less compactly, than many other folding bicycles.
