I use a very similar one I got many years ago when I have to work on SB Cruiser (which probably weighs a few times what yours does :lol: ).
At one time I had a couple tiny "bottle jacks" I was going to install on the old CrazyBike2 (and would have built into the SB Cruiser) but they disappeared sometime after the fire, along with the pair of small scissorjacks (that actually weighed more and were a bit larger).
If you want something even smaller and lighter than what you've got there (in case you need to carry one with you), you could go for a bottle jack. Some of them are quite small but still have enough jacking height to be useful (as small as 5 or 6" retracted, 10-12" extended; there are bigger ones if you need them).
