SPINNING BIKE EQUIPPED WITH A SENSOR DEVICE
First Claim
1. A spinning bike including:
- a frame;
a flywheel connected to the frame;
a magnetic resistance device for providing magnetic resistance against spinning of the flywheel;
an adjustment assembly operable to move the magnetic resistance device relative to the flywheel, wherein the adjustment assembly includes;
a tube secured to the frame and formed with a stop at an end and a cover at another end;
a rod extending throughout the tube and including a pinion and a thread so that the thread and a portion of the pinion extend beyond the stop of the tube; and
a sensor device connected to the frame and used to measure the magnetic resistance, wherein the sensor device includes;
a variable resistor;
a rotational axle connected to the variable resistor; and
a gear connected to the axle and engaged with the portion of the pinion that extends out of the tube, the electric resistance of the variable resistor is changeable by rotating the axle and translated into the value of the magnetic resistance exerted on the flywheel by the magnetic resistance device.

Abstract
A spinning bike includes a frame, a flywheel connected to the frame, a magnetic resistance device for providing magnetic resistance against the flywheel, an adjustment assembly for moving the magnetic resistance device relative to the flywheel, and a sensor device for measuring the magnetic resistance. The adjustment assembly includes a rod extending throughout a tube. The tube is secured to the frame and includes a stop at an end and a cover at another end. The rod includes a pinion and a thread. The thread and a portion of the pinion extend beyond the stop of the tube. The sensor device includes an axle connected to a variable resistor and a gear. The gear is engaged with the portion of the pinion that extends out of the tube. The electric resistance of the variable resistor is changeable by rotating the axle and translated into the value of the magnetic resistance.
