The folded scooter (22kg) allows you to carry yourself in one hand up the stairs (underground/overground passages, stairwells/landings, .. ) without a break (for me, lifting to the 3rd floor is not a problem). The steering wheel is high and not adjustable (with a height of 190cm it will ride comfortably). He can only drive around a well-maintained city, and even then, very carefully (a clearance of 7 cm does not allow this, the bottom cover is plastic, and the plastic in the shock absorber instantly breaks and they won’t repair it for you under warranty! ). For a pilot weighing 90 kg (or less), the scooter is suitable. I myself am 87kg + 3kg clothes, total 90kg, I don’t experience any special problems, but the front shock absorber has already come to an end. You can load it with 150 kg, as indicated in the instructions (riding together), but you must understand that such a weight will quickly kill this scooter (at least, the cord inside the tire will be exposed, the shock absorber of the steering rack will be killed, the resource of the motor-wheel and all bearings). Both tires are chambered, inflatable, according to the instructions it is recommended to inflate to 4 atmospheres, but they become oak and unstable to damage, so I recommend inflating 3 atmospheres. On this scooter, changing the rear tire or tube is extremely difficult and time consuming. You can connect via android application "KCQ scooter" via bluetooth and enter a 6-digit anti-theft code: when turned on, the scooter will not go by itself, but it can still be rolled away / carried away manually, can be used when the scooter is in your sight at a distance a few meters (you went to sit on a bench in the park or have a bite to eat in a street cafe outside, and it is very problematic to carry a cable with a combination lock with you - you simply cannot attach it to anything on this scooter). The battery is charged from full discharge to full charge - nine and a half hours. The official Midway warranty in 2022: 6 months for the motor-wheel (but not more than 1500 km), 3 months for the battery and controller, and there is no warranty at all for the mechanical parts of the case.
