Claim:
A device for transportation comprising: a platform having a ride surface to support a user, the platform extending in the direction of travel of the device, and the platform having a forward portion and a rearward portion; a pair of wheels adjacent either the forward portion or the rearward portion and at least one wheel adjacent the other portion; an axle extending between the pair of wheels and located in an axle mounting system supported by the platform; a brake mechanism supported by the platform and comprising a contact portion and an actuation portion, the brake mechanism having a first position in which the contact portion exerts a force on a wheel adjacent the rear portion and a second position in which the contact portion does not contact the wheel adjacent the rear portion, the brake mechanism being biased toward the first position, the axle mounting system comprising a first bearing surface and a second bearing surface extending in a direction substantially parallel to the axle, the first and second bearing surfaces being inclined with respect to the ride surface and forming a V-shaped groove having an unobstructed opening facing a surface upon which the device is ridden, the second bearing surface comprising a pivot member about which the axle can pivot to provide, in use, a turning function for the device; at least one compression member proximate one of the pair of wheels, an innermost edge of the at least one compression member being laterally spaced from the pivot member, and the at least one compression member being configured to be compressed by the axle against the second bearing surface, wherein the first bearing surface provides a surface that supports the axle during pivoting of the axle and turning of the device.
