Are you over 300 lbs? While it could be fine, that’s the structural weight limit Specialized rates it to. I would look at some of the bikes rated for larger folks if you were.
If you’re above 250 but below 300, you’d probably be ok but don’t exceed 300 with cargo.
If you are cresting 300 and want a full featured ebike, the only other suggestion I have is Riese and Müller. They may be expensive, but they use good components and at least some of their bikes (don’t remember which specifically) are rated to 350 lbs.
Edit - autocorrect typo
I am. In my experience the wheel is the most important part along with maybe the suspension fork.
I started bike commuting in 2000 at 400lbs and lost 170lbs in about a year and a half on an entry level Trek mountain bike that definitely wasn’t rated for my weight. I then spent the next 8 years riding a Trek 1000 road bike. Once again a hand-built wheel did the trick, even though I was never below 250 (I’m legitimately just a big guy that will never be that light, even when I’m eating perfect and cycling 35 miles a day) - the bike was great for me.
Unfortunately I was hit by a car a little over 10 years ago and that messed me up for quite a while. When I could finally get back on the bike regularly and not worry about getting hit, I’d gained some weight and started riding eBikes. Same drill. A well-built wheel and I don’t really have trouble. I didn’t have any trouble on my Trek Verve+ 3 (which I think has 2 piston brakes) and I don’t anticipate having trouble on the Vado once I get a wheel built.
I was just surprised by how insistent the salesperson was about the 4 piston brakes. My other bike is a Brompton with rim brakes. Maybe not advisable, but it can be done. And it’s not like I’m off-roading. I’m just running errands and getting around town.
All that said, since I’m starting fresh this time (I just sold my Tern) I may take this opportunity to spring for the lost stable and best braking Vado model I can (5.0, standard frame, non-SL), just to hedge my bets.
I’ve looked at the Riese and Mueller bikes, but it’s not clear to me what the geometry on the bikes is and I am trying to find a specific fit that the Vado meets.
