To prevent a center of gravity of a wheel from being biased toward one side of an axial direction.SOLUTION: A power-assisted bicycle includes a wheel 3, a fork 4 located on one side in an axial direction of the wheel 3, and a motor 5 provided at the fork 4 and supporting the wheel 3 from one side of the axial direction so that the wheel can rotate about the axis of the wheel. The wheel 3 includes a hub 10 connected to the motor 5, and spokes 13 stretched from the hub 10 to a rim 11 of the wheel 3. The hub 10 is displaced onto the other side of the axial direction. The motor 5 can apply a driving force in a direction around the axis to the wheel 3.SELECTED DRAWING: Figure 1

    【課題】車輪の重心を、軸方向の一方側へ偏りにくくすることである。【解決手段】車輪3と、車輪3の軸方向の一方側にのみ位置するフォーク4と、フォーク4に設けられ、車輪3をその軸回り方向に回転可能なように軸方向の一方側から支持するモータ5と、を備え、車輪3は、モータ5に接続されているハブ部10と、ハブ部10から車輪3のリム11にかけて架け渡されているスポーク13と、を備えている。ハブ部10は、軸方向の他方側に偏位している。モータ5は、車輪3に軸回り方向の駆動力を付与可能である。【選択図】図1
