Ursus JUMBO at all by its width of standfesteste stand, I know. Bicycle with one side of the Trunk a firm, heavy bag or even climbing children in the trailer are not a problem, the wheel does not fall to. In order for the JUMBO can be wide without being while pedaling in the way he uses an ingenious folding mechanism. The processing of the part perfectly and - without my having now used it already longer - I say it is also very durable. So it looks in any case. The supporting parts are made of aluminum, is thereby achieved a very tolerable weight - but it is not really easy. Can not that supposed to keep what. Avoid plastic feet damage on the ground. The plastic looks to me like a durable, glasfaserverstaerktes material. The fixing is done by a M10 screw usual with bike racks. A very long screw and a solid backstop plate is included. The panel recommended to use at this great stand, even if the frame of the wheel a corresponding disk is already welded. There is no rubber shim at the plate, so topsy make an old bicycle inner tube little piece, so that the paint remains intact. The stand is quite intolerant in terms of Schraubenlaenge, the probability that you have to saw off the screw is high. The supplied screw has an outer hexagon head (as a mother), which can in some context be difficult, because you do not beikommt with the key. For installation it is advisable to have ready are one of the usual screws with hexagon socket head. And situated in the stand thread, a self-locking M10 nut, ensures that the fixing screw will not loosen, but is somewhat inconvenient during installation. When the stand but for now your turn, then he is super.
The JUMBO is easy to use and I do not see any danger of being injured as during normal operation. The force which is not so high you need for flaps and yet he remains firmly in place.
Attention, by the width of the running cranks / pedals no longer pass but get stuck at the unfolded stand. This usually does not matter, because no one wants to come on the bike parked in the pedals. However, it can be inconvenient when Rueckwaertsschieben in a Parkluecke into it because the abutting cranks prevent the rear wheel can turn.
Before buying you should measure it for safety's sake, that the stand has the proper height. For he is not height adjustable. The 28 "version comes in 30cm, what with most 28" wheels is fine. There is also a 26 "version, which is not so high. Shortening of the legs is by design not possible (we would Kunststoeffuesse sawing).
I would buy this stand in there again, because I know of no comparable stable alternative. Nevertheless, I could a few small improvements to the product imagine: more space for long fixing screw in the stand it, so you do not have to saw off. Supplied screw should have a hex instead Hexagon-head have, protective rubber for the backstop plate should be there.
--------
Update 15 months later: The stand still works perfectly without noticeable degradation, durability seems to be so given.
--------
Update after 2.5 years: The plastic feet have worn anything but is ne purely cosmetic thing (spare parts offered online by the way). Function is like the first day.
