      Nice product... BUT... I had to do a bit of work when I received it. One of the tyres was not seated properly on the rim and as a result it fouled the front brake block and was potentially dangerous.
      If I had bought it from the shop the engineers would probably have spotted it but I had it delivered direct to my house ...
      hame really as the bi
