Backlash, almost every part of this infernal stool creaks godlessly and tends to fall off (so far nothing has fallen off, but it only seems that way by sounds); The quality of the wheels and the chamber for them is disgusting, the rear wheel was pierced twice, as a result, I decided to take a smarter one without a chamber, after the trip my butt aches, but at least I’m not afraid of punctures (surprisingly, the front wheel behaves like a solid machine wheel - it doesn’t pierce easily , does not descend, does not erase, but it is understandable, my carcass does not press on it, unlike the back one); The wrenches in the set are terrible if you want to tighten a loose nut - no problem, they are enough for you, but if you want to tighten it well, straight from the heart, you would rather twist the wrench itself into a steering wheel than tighten the bolt; All the "illumination" is as weak as possible, they will certainly see you, but with a front lamp you will not see anything further than the light of the same telephone flashlight (5-6 meters), also from the cold (from +5 to -5 and below, below minus 7 is not traveled) lights (if they were turned on during such a trip) are "jammed" glowing constantly without the possibility of turning off (even brake lights, even after turning off / on); Illumination on the sides is not disabled; Repulsive mounting and location of the motor wheel, with a similar mounting, removing the tire without removing the hydro insulation becomes impossible (except when you have a set of special tools for this business and a couple of very strong people, including you); Super stiff, non-adjustable springs on both wheels, maybe if your weight is 100+, the ride will be more pleasant, but it’s very hard for me to drive on Hong Kong roads, and Hong Kong apparently loves brick paths very much, and pedestrian roads are apparently designed for off-road radio-controlled testing machines.
