Not a well finished product all all. Had potential with good rubber wheels and a decent hub, however the shaft and bearings are utter rubbish. Mine came with bent shafts and damaged bearings. Not a free spinning wheel, in it's initial condition. It would be applying a braking force without the electromagnet. Went to the local small parts store and purchased high carbon shafts, decent bearings and a couple of circlips. Should be happy days for here on in. Should have bought a Taiwan Tornado electromagnetic brake instead and avoided the hassle!
