Bearings:
The standard built-in ball bearings are of medium quality - both in terms of service life rolling resistance. I'm booted up with the scooter sometimes the flattened curb, the ball bearings are therefore unfortunately knocked out fairly quickly. I got on base guarantee quick and easy replacement by the manufacturer sent - but I have been with the camps not entirely happy and had me with a little better quality and lower rolling resistance (not for Hudora) bought stock, so I'm happy now. But Hudora spare stock not cost the earth, so that one could exchange also often times for less money.
Tires:
The tire left a mixed impression. On one hand, works with air tires, the brake very well and when the tires are inflated to the prescribed limit also, you can go relatively quickly. A major advantage of pneumatic tires is the "ride comfort" - ie you do not feel any sidewalk groove or any rough pavement - the usual for solid rubber tires and plastic tire vibration on this road surfaces thus omitted. Unfortunately, the tire holds despite the valve caps but not very long full pressure, so that one week, at the latest, must re-inflation after 2 Weeks 1 x. It's annoying in the long run, of course - even if you can do it at a gas station. Pumping not for longer, the tire goes from the air, which is indeed harmless, because most of driving enough (remaining) air in the tire is available - but it suffers from the speed and the rolling capacity of the scooter as a whole - so you feel slowed down and slowly and must be more and more often repel the ground. I still have time "Hudora 14689 - Scooter Roller Set 205mm + ball bearings" tried, which are lack of air chambers course at each location always fully there - but have in turn the disadvantage that the above-described vibration of pavement and grooves / joints of sidewalks throughout the scooter frame go through. In rain and snow this hard tires have less grip again - also works the brake here worse - the tires have it even in rain and snow sufficient grip and the brake works even better when it rains. It needs to decide what compromises he takes on himself in terms of tire choice and how fast it would go every man for himself and his perception of comfort.
Shelf life:
Speaking of winter, rain and snow: With water scooter comes along well and rust so far either. The manufacturer specifies that it is also relatively insensitive to water - but he empiehlt to dry after a rain ride the scooter with a cloth, so that it can not corrode. I have not done so far and I can still find no rust or Beeintächtigungen the material. Rides in the snow cut with pneumatic tires also go - but I mean with snow rides of course rides on a thin blanket of snow - that's not a Cross Roller = ;-).
Stand:
Negative the Attached stand noticed - what you want no one knows: Once some uneven pavement is there, is on the stand and scars from. The same with flattened curbs which you want to boot. By now I have got used to the scooter at these points here to raise something, so that it can not scrape - I personally consider the stand as superfluous, since it has very high spring tension and can not be time just emerged with his foot. Mostly you have to bend and extend it by hand. I can not stand the abgewinnen.
Folding mechanism:
The collapse of the whole scooter works quite well and the model is very quickly assembled and disassembled again, so it easily fits in a trunk of a car. Some getting used to are the handles, which can be pulled out of the handlebar due to the folding mechanism, so that they take up less space when folded. This handle ends frog pond also happy times in the assembled state of the handlebars so that they push every now and again in the handlebar and position needs. Fall they can not because they are held by a rubber band, but a little more strength, "local" or a little less slip-out property would have been desirable - but there are worse and the driving ability does not suffer in any case below. So rather a haptic problem.
Conclusion:
Bottom line, we can say that the scooter is reliable and up to the mediocre ball bearing and the relatively fast tire pressure tire losing air actually has good dimensional stability and has no signs of wear. I would buy it again so - just "pimp" something other ball bearings. Which tire is then ultimately takes - is a matter of taste. A tire changing is the way even with ball bearings change a 5 minute thing - so you depending on the season and according to his own needs to choose the best tires here. I can imagine that I might someday the tires again out hole again - especially if again is rainy or winter time.
