Think of the Becker as a center stand for the bike that just isn't permanently attached. So no, it's great for standing the bike upright for cleaning or for winter storage to get the bike off the tires so they don't flatten, but for more serious mechanical work where you have to detach wheels etc this is not it.
Which is why I complemented mine with a hydraulic lift. But since I like to overdo when I could merely do, I spent over 100 euros on an adapter plate from another German outfit, Kern-Stabi. Impressive design, it's incredibly thick and heavy, like they carved off the side of a Battleship and bent it into shape... this creates a perfectly flat lifting surface under the Rocket when attached to the two holes in the frame. On that surface you then lift with a normal hydraulic bike lift. They can be had for about 100 euros too if you go bargain basement from places like
http://www.mandp.com for instance, they have central hydraulic lifters for that kind of money that lift 1500 lbs. Lots of people have them and they do the job.
I bought a Bahco BH1M1000 after seeing it at the local bike show. It's a cross between a garage jack and a bike lifter, and tops out at one metric ton. The ****ed thing weighs some 67 kilos of grade A steel, it's a beast. Feel very confident in its capacity to hold the Rocket... but the sum total for the expensive (but extremely solid) adapter plus the jack shot past 600 euros.
DYI:ing some adapters for the Rocket and getting a more modest lift and you can get the bike in the air for a little over a 100. Then you just have to find a way to prop the front up if you take the rear off, the shift in weight without a rear wheel would no doubt drop the bike off the stand otherwise. Straps, hooks in the ceiling, what have you.
