I searched in vain for a double leg stand for my Interceptor. If you do find one, please post a link. I've found on other bikes, that double leg stands work well on fairly level ground but I ride mostly trails with irregular surfaces. For trails, I much prefer a single leg stand.
The problem with the OEM kickstand on the Pedego Interceptor is, the ground contact point is too far forward. This makes it unstable, especially with weight on the rear rack. I solved the problem on my Interceptor by adding a shim:
View attachment 199777 View attachment 199778
This moves the ground contact point about 5" to the rear, making the bike much more stable
View attachment 199780 View attachment 199781
This solved the instability issue for me, even with 30# of gear on the rear rack.
The shim is made from a piece of 1" x 1/8" thick aluminum angle, available at Home Depot:

I used a screw to hold the shim in place but a metal rated epoxy works just as well.
