Recumbent bicycle-powered generator using an alternator, flywheel and sprocket and chain system

A human-powered generator comprising:

• a frame;
• a recumbent seat adjustably mounted on the frame;
• a pedal crankset comprising a pedal operatively connected to a crankset sprocket, the pedal crankset being rotatably mounted at a crankset bracket on the frame;
• a flywheel rotatably mounted on at a flywheel bracket on the frame, the flywheel comprising:
• a flywheel-crankset sprocket attached to rotate with the flywheel;
• and
• a flywheel-countershaft sprocket attached to rotate with the flywheel;
• a countershaft rotatably mounted at a countershaft bracket on the frame, the countershaft comprising:
• a countershaft-flywheel sprocket attached to rotate with the countershaft;
• and
• a countershaft-alternator sprocket attached to rotate with the countershaft;
• an alternator mounted at an alternator bracket on the frame and comprising:
• an alternator drive shaft;
• and
• an alternator sprocket mounted to the alternator drive shaft;
• a crankset-flywheel drive chain operatively extending between the crankset sprocket and the flywheel-crankset sprocket;
• a flywheel-countershaft drive chain operatively extending between the flywheel-countershaft sprocket and the countershaft-flywheel sprocket;
• and
• a countershaft-alternator drive chain operatively extending between the countershaft-alternator sprocket and the alternator sprocket;
• wherein the crankset sprocket, the flywheel-crankset sprocket, the flywheel-countershaft sprocket, the countershaft-flywheel sprocket, the countershaft-alternator sprocket and the alternator sprocket are sized such that a pedaling cadence at the pedal crankset of between approximately 60 rotations per minute (RPM) and approximately 100 RPM achieves an alternator drive shaft RPM of between approximately 2,000 RPM and approximately 5,000 RPM.
