I do not have the bike carrier yet, should arrive the end of this month or early next. I need to try it with the larger ebike, we have 2, his & hers just to see if I have to raise it or not. Never thought of visibility of lights through the spokes. Knew I came here for a reason. Might need to raise it a bit just for ground clearance if nothing else, being extended from the body & all.
And the carrier I bought comes with a stabilizer, so if I do get a riser I'd only need one for that.
Thanks for all the good suggestions and such.
Stay safe.
