I've found most portable stands lacking for things like bottom bracket work. In fact, the standard heavy base Park shop stands aren't much better if you have to put force into a wrench trying to deal with a stuck, overtightened or corroded fastener. That said, I've owned and used Minoura and Park stands and currently have two Feedback (formerly Ultimate) Sports portable stands. Working on our tandems, I typically have to have one wheel on the ground when mounted in the stand to have stability. You asked for ability to support 60lbs so that suggests to me you're interested in using it on a heavy e-bike. I think you'll be disappointed unless you buy a very heavy duty stand. Our recumbent tandem weighs about 50 lbs and the stand is useful but it's an unwieldy combination due to the weight and length.
Good luck in your quest.
