I hear you Worm!
I have an older Vado (yes 2018 could be considered older in ebike world). And I too seemed to feel every concrete seam, road crack, and repair. It came with 2” Electrac tires which I felt were very harsh and unforgiving even at the lowest recommended pressures. And also made the bike very tall for my vertically-challenged legs. I switched them to 47 mm Trigger tires and it helped, especially in handling and cornering.
Do you have the original seat post on your Vado? The
best thing I added was a
suspension seat post. I chose the Kinect based on the input of many of the great members of this forum. Of course there are other brands, especially when you consider price. I liked it so much I put one on my 2nd ebike. No more hammering over the crummy roads!
Note: the customer service rep at Kinect said ebikes tend to ride somewhat harsher because of the increased weight combined with the faster speeds. Don’t know about that. All I know is I no longer feel so many bumps.
Please post what works for you.
