I bought the Park tool PCS-4 as well...after buying a cheapo $85 tripod stand that I could not apply any torque on bolt without tipping. It pretty much fell apart after three months. Lesson learned.
Given how heavy my bike is, I still have a hard time getting the bike up into the stand safely and without strain. More often than not, I ask my wife to help clamping the bike into the jaws while I lift the bike and hold it in place.
Given that I am now maintaining four ebikes, with a bike in the stand at least three time per week and ride an average of over 600 miles per month, I bit the bullet and ordered the EVT (Efficient Velo Tools) EZ lift Repair Stand.
The EVT stand is made start to finish in Portland, Oregon. It sits on a steel base plate that weights 112 lbs. The clamp slides up and down on a 7 foot pole with a counterweight hidden inside. You clamp the bike to the stand while the bike is on the floor and lift it up with up to a 30 lb. a counter weight on a pully make lifiting smooth and easy. When the EVT Easy lift arrives I will have a good deal for someone on the ParkTool. The EVT is expensive but way less so than dealing with some injury from the physcial strain or damage to a bike that might result from lifting a heavy (and costly) ebike with one hand while clamping it into a stand with the other.

[Hi Alaskan,
You might be interested in this item from Harbor Freight:
https://www.harborfreight.com/1-ton-capacity-foldable-shop-crane-61858.html.
I have actual hands-on experience with this fold-up crane, thanks to a 74 year old, 6'3", 250 pound VietNam vet neighbor who has a propensity to occasionally lose the feeling in his legs and collapse onto the floor. His 84 year old brother is only 5'5" tall and 120 pounds, thus he cannot lift/assist his large brother in getting up and onto a chair. I encounter these two gents courtesy of an EMS unit that had to be called upon to raise the fallen fella. The EMS folks were very nice, but they also inferred that these visits could not be a regular thing-- assisted care living would be their eventual solution. I am 68 years old, weigh 185 pounds, and there is no way that I'm gonna take a chance of screwing my own self up while trying to assist dead-weight Big Guy up onto a chair.
Anyway, I chatted with the brothers and we formed a thought in regards to the matter. This most excellent fold-up crane was the result. There is a Harbor Freight store a few miles away, so we went over to check out the floor display. Needless to say a remedy to their "lifting" problem was a done deal-- a 4" fat tire from my ebike, its' inflated inner tube, and a large 10" Harbor Freight clamp rounded out the contraption. While horizontal (on the floor) he could be shimmied up thru the tire and, with his upper body/arms thru the tire, be lifted perfecto-amundo. And, hey, it worked out great.
I assembled the crane and, thanks to a timely visit to the local VA hospital by those fella's, I was able to dink around with this crane for 2 days in my condo.
It folds up/collapses to an area the size of your ebikes handlebars squared. Also, if you have a garage wall, etc. to store it next to, you can leave one leg down and locked while the other leg is folded up out of the way. The only "down side" to this unit is that the ebike will swivel on the chain. However, that can very easily be rectified by thinking outside the box in the form of fabricating a fixed bar-type bracket to mount onto the square top boom and then onto which the ebike frame can be secured-- no need to even use the seatpost as your clamping location. In addition, the handlebars can be used as an additional mounting /support location just by using bungee cords/ web straps thrown over the top bar of the crane.
This crane is a quality item. The only downside is that Harbor Freight does NOT offer shipping, so you either need to live near a store or be willing to order another similar brand (ship-able) off the internet.
