A bicycle stand includes a base, a connection unit and a support unit. The base has first and second arms non-parallel to each other. The connection unit is arranged between the first and second aims. The support unit is detachably mounted on the connection unit and is transformable between a folding position and a using position. The support unit is detached from the connection unit when the support unit is in the folding position. The support unit is attached on the connection unit and is adapted to engage with a spindle in a crank-arm of a bicycle to support the bicycle in an upright position on a surface when the support unit is in the using position.
