There's really good current info in this thread:
I'd love some recommendations on an affordable bicycle repair stand that can take the 50-60lbs of an ebike. I don't want to spend the $$$ for the Park Tool if I don't have to, but also don't want to waste money on junk that won't work.

I'd recomend the Park Tool PCS-10, but they redesigned it and now call it PCS-10.2. It looks like there are still some 10's left on Amazon, but I think once gone that's it since Park no longer lists it on their website. There are a few other good stands on the market. BTW I'm 6'2" and I can get the PCS-10 at working height. Nice stand, shame it's been changed.
