The battery pack and electric bicycles

The present invention discloses a battery pack and electric bicycles. The present invention provides a less likely subjected to vibration, impact and shock, and the like having stable characteristics electric bicycle battery pack, the battery pack and use. A battery pack comprising: a battery connecting structure, a plurality of flat batteries are placed in the cell connection structure; damping member, the damping two mutually intersecting at right angles along the outer surface of the battery connecting member structure direction; and a gap between the outer surface of the housing section, said housing section housing the battery connecting structure, so that a direction of said shock absorbing member is a positive gap and reducing the other direction gap between the outer surface of the shock member is a negative clearance.
