Here is a follow up and thoughts/suggestions on this Ebike loading/carrying rack I got, https://www.amazon.com/dp/B07XFGY7ZT/ref=sspa_dk_detail_3?
I have been testing this rack out and very pleased with it, very stout design and well built, carries the Wart Hog MD 750 (90#'s+) with no problems.
I did find a couple minor issues,
1. The loading ramp angle is quite steep, this rack sits approximately 24" AGL = (above ground level) when mounted on my Toyota PU and even taller when on the F-370 1 ton PU.
I have to lean the bike over at a slight angle to guide it up the ramp, ramp OAL = over all length is 39". The handle bars are 48"+ AGL and add the 24"+ height of the ramp, makes for a long reach for anyone less than 6' tall.
When the bike is leaned over to go up the ramp, the lip of the ramp will also slip out of the ramps tongue & groove slot. I cured this problem via using this longer ramp for greatly decreasing the loading angle which solved the above problem.
now it works very well, plus has pockets/holes in the ramp's face for the tire to bite into when loading.
2. When figuring out just where to have the recessed slots/pockets for the wheels to sit in, it is VERY HARD to move the bike forward or backwards with approximately a 20" long pocket length, (this allows the tire/rim to drop below the bolt holes of the carrier arms, so a 1/2" dia bolt can been inserted thru the carrier arms to lock the wheels in place.) Walk mode will not move the bike out of these deep slots.
So I found that removing just one bolt, which allows a approximately a pocket slot length of 11/12" works to hold the 31" wheels in place and have the bike centered over the ramps center bar area.
I use 2 of these type of ratchet straps: (No hooks).
double wrapped around the ramp/tires which holds the wheel in place.
I use 2 of these soft straps, around the Jct of the seat and cross bar tubes of the bike. https://www.amazon.com/Xstrap-Soft-Tie-Down-Straps-18inch/dp/B07GVHKV1H/ref=sr_1_6?
Then I use 2-3' long ratchet straps to attach to the soft straps for securing to the center of the bike to the ramps carrier center bar.
When I finish loading the bike, I use the fold up ramp and attach it to the same spot as the OEM ramp was attached to. There is a piece of expanded metal HEAVY GAGE 4-3/4" wide by 30+" long that just fit between the ramp rails, before I first load the bike this HD Expanded metal mesh is slid back to cover the tire slot hole of the loading ramp for easy loading, and this mesh is also slide forward to cover the tire hole when unloading.
