>>1938288Your best bet is the Razr A6. It has solid wheels, but they're the biggest in the market.
And it's not like the solid wheel types can't do a bit of gravel or dirt. There was a Japanese guy who traversed Australia, South to North, on a Hudora brand kick scooter. He had to change wheels twice, and get his scooter welded back together after it cracked in the middle, but he made it. What a mad lad.
