Abstract
An exercise bike includes a frame, a rotor assembly and a drive assembly mounted on the frame, where the drive assembly is configured to drive rotation of the rotor assembly, and a cover configured to at least partially cover the rotor assembly. The components of the drive assembly and the rotor assembly include structures that improve the performance of the exercise bike, including but not limited to a strong and rigid construction and improvements in belt tracking, user feel, effort consistency, synchronization, and rotor performance.
Claims41
An exercise bike comprising:
- a frame configured to rest on a ground surface and having a seat configured to support a user;
- a rotor supported by the frame, the rotor comprising a hub supported by the frame for rotation on a first axis, a sprocket operably connected to the hub, and a plurality of blades connected to the hub, and a connection structure connecting the blades to the hub, wherein the hub, the sprocket, and the plurality of blades are configured to rotate together about the first axis, wherein the hub comprises first and second circular plates and a cylindrical center body extending axially between the first and second circular plates, the center body having a smaller diameter than the first and second circular plates, and wherein the plurality of blades includes a first blade having a proximal end connected to the hub and an elongated body extending outward from the hub to a distal end, the elongated body having first and second elongated sides extending between the proximal and distal ends, wherein the first blade is formed as a single integral piece and is engaged by the connection structure to connect the first blade to the first circular plate of the hub at a first connection point proximate the first elongated side and to connect the first blade to the second circular plate of the hub at a second connection point proximate the second elongated side, wherein 70-90% of a weight of the rotor is located within 75% of a maximum diameter of the rotor;
- and
- a drive assembly operably connected to the rotor to drive rotation of the rotor, wherein the drive assembly comprises a pulley assembly supported by the frame operably connected to the sprocket of the rotor and a pedal assembly connected to the pulley assembly to drive rotation of the rotor through the pulley assembly.
