Saw this marvellous contraption parked out the front of my work a little while back. I’d say it handles with knife edge precision.
What would have been interesting was if the creator of this beast had installed a centre stand and some sort of hookup with the wheel that allowed the bike engine to drive the grinding wheels too.
Still: I like the idea of a trade that comes to you, with minimal vehicle footprint and then putts off to the next job.



The only problem is that the engine on the back of it is probably more powerful than the one in the bike itself.
