A planetary gear system in an exercise machine featuring a flywheel; an axle shaft positioned through the center of the flywheel, a sun gear disposed on the axle shaft and fixedly attached to the flywheel, a housing disposed on the axle shaft, a planet carrier fixedly attached to the axle shaft and disposed in the housing, and a ring gear fixedly attached in the housing. One or more planet gear wheels are rotatably attached to the planet carrier. The planet gear wheels can rotate independently of the planet carrier. Rotation of the axle shaft in a first direction rotates the planet carrier in the first direction, thereby causing the planet gear wheel to rotate in a second direction within the ring gear. Rotation of the planet gear wheel in the second direction causes the sun gear and the flywheel to together rotate in the first direction. |

1. An exercise system comprising:
(i) a planetary gear system comprising:
(a) a flywheel (105);(b) an axle shaft (110) having a first end and a second end, the axle shaft (110) is disposed through a center (106) of the flywheel (105), the flywheel (105) rotates independently of the axle shaft (110);(c) a sun gear (115) disposed around the axle shaft (110) and fixedly attached to the flywheel (105), the sun gear (115) rotates independently of the axle shaft (110);(d) a first crank (120a) and a second crank (120b) fixedly attached to the first end and the second end of the axle shaft (110), respectively;(f) a planet carrier (140) fixedly attached to the axle shaft (110);(g) a ring gear (160);(h) at least one planet gear wheel (150) rotatably attached to the planet carrier (140), the planet gear wheel (150) can rotate independently of the planet carrier (140), an outer surface of the planet gear wheel (150) engages both an inner surface of the ring gear (160) and an outer surface of the sun gear (115), wherein rotation of the axle shaft (110) in a first direction via the cranks (120) in turn rotates the planet carrier (140) in the first direction, thereby causing the planet gear wheel (150) to rotate in a second direction within the ring gear, rotation of the planet gear wheel (150) in the second direction causes the sun gear (115) and the flywheel (105) to together rotate in the first direction; and (ii) a pivot system comprising:
(a) a base (250);(b) a rotational bearing (520a) attached to the base (250) at an angle A, wherein angle A is between 30 to 50 degrees with respect to a plane of the base (250);(c) a bicycle frame (210) having a first handlebar support extension (215a) extending from a vertex of the bicycle frame (210), a second seat support extension (215b) extending from the vertex of the bicycle frame (250), and a lower extension (215c) disposed at a vertex of the bicycle frame (210), wherein the first handlebar support extension (215a), the second seat support extension (215b), and the lower extension (215c) intersect the vertex of the bicycle frame (210), wherein the rotational bearing (520a) rotatably engages the lower extension (215), wherein the bicycle frame (210) can rotate right or left with respect to the base (250), the planetary gear system (100) is integrated into the bicycle frame (210) at the vertex of the bicycle frame (210), wherein the bicycle frame (210) is solely suspended from the lower extension (215c) adjacent to the planetary gear system; and
(d) a recoil support mechanism (550), wherein the recoil support mechanism (550) comprises a first bumper (610a) or a first spring and a second bumper (610b) or a second spring disposed on and facing opposite sides of a planar recoil support gusset (620), wherein the recoil support gusset (620) is disposed perpendicular to the plane of the base (250), wherein the recoil support mechanism (550) is adapted to limit rotational movement of the bicycle frame (210) with respect to the base (250); wherein the base (250) is only attached to the bicycle frame (210) at a single point via the rotational bearing (520a) and the lower extension (215c). |
