Abstract
Disclosed is a recumbent bicycle having a frame with at least one tubular member having a lumen. Mounted to the frame are a rear wheel assembly and a transmission assembly. The transmission assembly can include a first gear, a second gear, and a chain that extends from the first gear to the second gear and through the lumen of the at least one tubular member. Pedals and crank arms can mount to the second gear, which is slidable relative to the first gear to vary the position of the second gear relative to a seat mounted to the frame. A suspension assembly can mount a pair of front wheels to the frame at a location intermediate of the first portion and the second portion of the frame. The bicycle enables riders of different leg lengths to use the recumbent bicycle, while the suspension assembly cushions the rider during use.
Claims21
A recumbent vehicle comprising:
- a frame having a first portion and a second portion;
- a rear wheel assembly pivotally mounted to said first portion of said frame, said rear wheel assembly comprising a mounting member mountable to said first portion and being received by one or more supports that aid with controlling rotational motion of said rear wheel assembly, said rear wheel assembly further comprising a shock assembly, said shock assembly comprising a plurality of interchangeable resistance members, each resistance member providing a different quantity of resistance to movement of said rear wheel assembly relative to said frame;
- a transmission assembly supported by said frame, said transmission assembly comprising a first gear mounted to said first portion, a second gear mounted to said second portion, and a chain extending from said first gear to said second gear, and
- a suspension assembly mounted to said frame, said suspension assembly being disposed between said frame and a pair of front wheels at a location intermediate of said first portion and said second portion of said frame and positioned to elevate said second gear relative to said first gear.
A recumbent vehicle comprising:
- a frame having a first portion and a second portion, said frame comprising at least one tubular member with a channel;
- a rear wheel assembly pivotally mounted to said first portion of said frame;
- a transmission assembly supported by said frame, said transmission assembly comprising a first gear mounted to said first portion and a second gear mounted to said second portion, and a chain extending from said first gear to said second gear and through said channel of said at least one tubular member, and
- a suspension assembly mounted to said frame, a pair of front wheels being mounted to said frame at a location intermediate of said first portion and said second portion of said frame by said suspension assembly, said suspension assembly elevating said second gear relative to said first gear.
A recumbent vehicle comprising:
- a frame having a first portion and a second portion;
- a seat mounted to said frame, said seat being pivotal relative to said frame;
- a rear wheel assembly pivotally mounted to said first portion of said frame, said rear wheel assembly comprising a mounting member mountable to said first portion and being received by one or more supports that aid with controlling rotational motion of said rear wheel assembly;
- a transmission assembly supported by said frame, said transmission assembly comprising a first gear mounted to said first portion, a second gear mounted to said second portion, and a chain extending from said first gear to said second gear, and
- a suspension assembly mounted to said frame, said suspension assembly being disposed between said frame and a pair of front wheels at a location intermediate of said first portion and said second portion of said frame and positioned to elevate said second gear relative to said first gear.
A recumbent vehicle comprising:
- a frame having a first portion and a second portion;
- a rear wheel assembly pivotally mounted to said first portion of said frame, said rear wheel assembly comprising a mounting member mountable to said first portion and being received by one or more supports that aid with controlling rotational motion of said rear wheel assembly;
- a transmission assembly supported by said frame, said transmission assembly comprising a first gear mounted to said first portion, a second gear mounted to said second portion, and a chain extending from said first gear to said second gear, and
- a suspension assembly mounted to said frame, said suspension assembly being disposed between said frame and a pair of front wheels at a location intermediate of said first portion and said second portion of said frame and positioned to elevate said second gear relative to said first gear, said suspension assembly comprises a pair of leaf springs mountable to said frame assembly, each of said leaf spring being interchangeable and selectable based upon the weight of a rider of the recumbent vehicle and dampening provided by said leaf springs.
