Drive assembly for a bicycle

A drive assembly for a bicycle comprising:

• a crankshaft;
• a pair of crank arms rotationally fixed to the crankshaft for driving the crankshaft;
• a traction motor operatively connected to the crankshaft for driving the crankshaft;
• a planet carrier disposed about and coaxial with the crankshaft, the planet carrier rotating relative to the crankshaft;
• one of a first sun gear and a first ring gear disposed about and coaxial with the crankshaft, the one of the first sun gear and the first ring gear being connected to and driven by the crankshaft;
• at least one first planet gear rotationally connected to the planet carrier, the at least one first planet gear rotating with the planet carrier relative to the crankshaft,
• the one of the first sun gear and the first ring gear engaging and driving the at least one first planet gear;
• at least one second planet gear rotationally connected to the planet carrier, the at least one second planet gear rotating with the planet carrier relative to the crankshaft,
• the at least one second planet gear being operatively connected to the at least one first planet gear, the at least one first planet gear driving the at least one second planet gear;
• one of a second sun gear and a second ring gear disposed about and coaxial with the crankshaft, the one of the second sun gear and the second ring gear rotating relative to the crankshaft,
• the at least one second planet gear engaging and driving the one of the second sun gear and the second ring gear;
• a drive sprocket disposed about and coaxial with the crankshaft, the drive sprocket rotating relative to the crankshaft,
• the one of the second sun gear and the second ring gear driving the drive sprocket;
• and
• a control motor operatively connected to the planet carrier for driving the planet carrier about the crankshaft.
