front wheel assembly 前轮部件
Abstract（简介）：
A front wheel drive system for a bicycle which can be installed on a bicycle to drive the front wheel by rocking the handlebars back and forth. A chain positioning and support mechanism is attached to the handlebar of a bicycle. The handle bar is attached to a rotatable outer sleeve of a handle bar stem. A rocker switch in the outer sleeve selectively locks the handle bar relative to the stem or allows the handle bar to rotate about the stem. A chain attached to the chain positioning and support mechanism engages a freewheel attached to the front hub of a bicycle and terminates in a spring connecting back to the chain positioning and support mechanism.
