A couple of the spokes where gone on my Bakfiets. I tried all the bike shops in Oxford and none of them stocked the right size. The previous owner had replaced the broken spokes with thin spokes (because no-one in Oxford stocked that size spoke) and these were essentially useless they could not take the load.
You can see how thick the spokes are and also a missing one.
I took the wheel off by resting the bike on an old railway sleeper and tied it to a bin to keep it upright. I’ve also taken the box off because I’m remaking it at the moment.
