Some brands of three-wheeled motorcycle include the Harley-Davidson Tri Glide, the Can-Am Spyder and the Polaris Slingshot. It is also possible to get conversion kits for a number of conventional two-wheeled motorcycles.
The Can-Am Spyder is designed with two front wheels and one rear wheel as well as a trunk located in the front. There are several different varieties that are comparable to common types of motorcycles, such as cruisers and sport bikes.
By contrast, the Harley-Davidson Tri-Glide has two rear wheels and one front wheel, with an appearance more comparable to a two-wheeled touring bike. Harley-Davidson also sells the Freewheeler, a smaller machine with a leaner profile.
