A roller skate having enhanced durability and stability is disclosed. The skate includes a platform for supporting a skater's foot. The platform includes a toe plate and heel plate connected by an adjustable connecting assembly. A front truck is affixed to the underside of the toe plate, while a rear truck is affixed to the underside of the heel plate. The front truck includes simple bracket arms for affixing a single front wheel which is capable of rotating, but not capable of tilting about the platform's longitudinal axis. Meanwhile, the rear wheel truck is mounted to the underside of the heel plate so as to permit both tilting movement about an inclined longitudinal axis, and also rotation about a transverse axis relative to the roller skate's platform. Preferably, the roller skate includes three wheels rotatably mounted to the rear wheel truck.

A roller skate as defined in claim 1 further comprising a pivot mount for mounting said rear wheel truck to said rear underside of said platform to provide a pivot allowing said rear wheel truck to pivot about a transverse axis relative to said platform. 3. A roller skate as defined in claim 2 further comprising a brake including a brake pad mounted to said platform, said brake pad positioned above one of said three rear wheels and rotatably mounted to said second wheel truck so as to engage one of said three rear wheels when said platform is pivoted rearwardly so as to engage and restrict rotation of one of said three rear wheels. 4. A roller skate comprising: a platform for supporting a skater's foot, said platform having an underside having a front and back;a first wheel truck secured to said front underside of said platform;a one or more wheels rotatably mounted in transverse axial alignment on said front wheel truck, said first wheel truck is mounted to said platform so as to not provide for tilting movement of said single front wheel about a longitudinal axis relative to said platform;a second wheel truck secured to said rear underside of said platform; andtwo or more rear wheels rotatably mounted in transverse axial alignment on said rear wheel truck so as to be in parallel axial alignment with said front wheel, said second wheel truck is mounted to said platform for providing tilting movement of said two or more wheels about an at least partially longitudinal axis relative to said platform. 5. A roller skate as defined in claim 4 further comprising a pivot mount for mounting said rear wheel truck to said rear underside of said platform to provide a pivot allowing said rear wheel truck to pivot about a transverse axis relative to said platform. 6. A roller skate as defined in claim 5 further comprising a brake including a brake pad mounted to said platform, said brake pad positioned above one of said two or more wheels and rotatably mounted to said second wheel truck so as to engage one of said two or more wheels when said platform is pivoted rearwardly so as to engage and restrict rotation of one of said two or more wheels.
