As pictured, that would not be road legal in the UK as there are no mudguards on the front wheels. They are a bit weird with the petrol engine, but this is going too far, probably only a research project that will be taken up by 50 or so customers. Not for me, I have an AR Plus 4!

How like 3 days? 2 days, 1 day, 4 days? AND how like 4th Grade, 2nd Grade, 5th Grade, they are both close and quite like 4th grade...............
