I’ve used Alien Drive Systems mounts for Paris (older v1) - they rotated on me and didn’t have grub screws to secure. Not my favorite. Before i fixed w/ JB Weld that board was stolen.
I’ve used Enertion mounts - love them and the CF bling. Range of flexibility on angles for non-standard setups is their only limitation. No issues, simple to setup and rock solid. Only Con is limited adjustment angle on drop decks or similar placement challenges.
DIYes mounts v3 (really their v1/v2 i think) - love the full adjustability and solid when setup correctly. Can be fiddly to get setup at the start, but beefy and uber-adjustable for any type deck a huge +.
I’ve setup one Psychotiller mount (used) and it keeps coming loose. Super frustrating. The truck clamp portion is too large, and the shim wiggles out when riding… JB Weld likely next to help fix.
I would get DIYes v3/v4, or Enertion’s without hesitation.
I’ve not tried the new DIYes v4 mounts might have some wheel size limitations if you run bigger wheels (>83mm like 90/97mm) since the belt tension uses the motor mount screws and usually the 4th under wheel can’t be reached. I have a set of the v4 on order to use, but might limit wheel size to a 83mm as a result. I had the same issue with Psychotiller’s mount.
