Front wheel drive mechanism for bicycle

A front wheel drive mechanism mounted in a bicycle including a front wheel, a pair of pedals adapted to propel by feet, a main frame mounted with the pedals, and a steering assembly mounted on the front wheel for steering same, the steering assembly being adapted to pivot relative to the main frame, the front wheel drive mechanism comprising:

• a first transmission assembly connected to the pedals, provided at one side of the front wheel, and connected to the main frame;
• a second transmission assembly connected to the front wheel, provided at the other side of the front wheel, and connected to the steering assembly;
• and
• a coupling device with limited swing capability adapted to transmit pedaling force from the first transmission assembly to the second transmission assembly, the coupling device being interconnected the first and the second transmission assemblies for allowing the first and the second transmission assemblies to dispose in a non-parallel relationship when the bicycle turns curves with the pedaling force transmitted from the first transmission assembly to the front wheel via the second transmission assembly.
