The wheels are off my two daughters old Bratz bikes ( they finally died so I stripped them for spares ) they rims were rusty so I painted them flat black , I don't know how many spokes they have and the tyres I got 2 pairs off ebay for $2.25 one set of kenda freestyle tyres went onto my sons bike and the other set which were a little to cracked for a bike are on the trailer . All up the trailer owes me $30.25 au the container was $20 and paint was $8.00 ( which I still have heaps of for next time
) and the tyres for $2.25 .
