New old stock, original Neiman fork lock for Motobecane 50v mopeds.
You can ditch your fork lock that's missing the key and drop this one in. Easy to install too! You just have to remove the top clip and press it out. Do the opposite to install this one. New old stock inventory.
Apparently these can fit some Peugeot 103 as well.
Motobecane part number 19798
