noun
bicycle parking area; bicycle parking lot
A designated place for parking bicycles, often found near stations or public facilities. Similar to 駐輪場, but 駐輪所 may imply a smaller or more specific location.
駅前に新しい駐輪所ができた。
A new bicycle parking area has been built in front of the station.
駐輪所以外に自転車を置かないでください。
Please do not leave your bicycle anywhere other than the bicycle parking area.
Compound of 駐輪 (chūrin, 'bicycle parking') + 所 (jo, 'place'). The exact historical derivation is uncertain, but the word follows a standard pattern for naming facilities.
