After reading the reviews on foreign websites, it was exactly what I expected.
1) The scooter has incredible quality. 100% aluminum, thick frame but lightweight.
2) The welds, as you can see, are professional and flawless for those who know. It is Made in China, but the Razor seal was not put there by chance.
3) It is foldable and has a clever simple mechanism (a small knob with a screw that tightens it) to make the connection of the vertical and horizontal parts more sturdy and minimize vibrations.
4) The distance from the ground is lower than other scooters, which has both a positive and a negative aspect. The positive is that the foot that remains on the scooter does not need to bend much to give propulsion with the free foot, so it gets tired and strained much less (believe me, this strain is the most difficult for those 35+). The negative is that you forget to pass through curved sections of the road, as it will hit the ground and scratch it. Personally, I prefer it this way so that my knee doesn't get tired, but it also depends on the routes you take.
5) Each handle is customized to an aluminum piece that attaches to the handlebar (one on the left and one on the right), while these two pieces are internally connected with rubber so that they do not get lost when removed. The positive is that you can remove them and the scooter takes up less space, for example in a car. The negative is that you have some vibrations from the handles, it doesn't feel as solid as a one-piece handlebar. I would prefer a one-piece implementation.
6) And let's move on to the reason I bought it, the inflatable tires.
Pros: Almost silent rides on different types of terrain and fewer vibrations as they act like shock absorbers. Believe me, on the concrete of Thessaloniki beach, which is supposed to be flat with small pebbles, I have ridden with a scooter with hard wheels and it gets tiring after 6-7 minutes. With inflatable tires, the ride is a pleasure.
Cons: The tires require a pressure of 4.13 bar/60psi/413kpa!! as stated in the brochure, which means you can only inflate them at a gas station (with a small hand pump, it's a challenge to reach 2-2.5 bar). If you leave them deflated, you will damage the tire from friction and it will puncture. It is good to have a small pressure gauge (6-7€) to check them regularly. Also, just like with bicycles, you will probably get a flat tire during the year, so you need to have a repair kit or a spare tire. The tire is 8 inches (200x50) and somewhat hard to find and slightly expensive (7-10€). I don't know if the usual 8.5-inch tires that electric xiamoi scooters use will fit. Finally, because the valve of the front tire is somewhat cramped and obstructed by the fork, you will struggle a lot to inflate it since the gas station pump doesn't easily attach. You need to get a valve extension to make the inflation easier.
If you can wait about 3-4 weeks for it to arrive (no one has it in stock), and the negatives don't bother you, go ahead. It cost me 110€ including shipping.
