Abstract

A bicycle exerciser including a base frame, a seat post connected to the base frame, a seat disposed on the seat post, a front stem connected to the base frame, a handlebar disposed on the front stem, a flywheel connected to the base frame pivotally, a chain guard casing disposed on the base frame, and a pedal connected to the chain guard casing wherein the bicycle exerciser is adjusted by a sectional adjustment device in order to control various sectional resistance of a flywheel.

Claims

exact text as granted — not AI-modified
1 . A bicycle exerciser having a base frame, a seat post connected to the base frame, a seat disposed on the seat post, a front stem connected to the base frame, a handlebar disposed on the front stem, a flywheel connected to the base frame pivotally, a chain guard casing disposed on the base frame, and a pedal connected to the chain guard casing, characterized in that:
