The ACE v1 reminds me of a Triking at the front, which according to this article, Liberty was looking into importing them so perhaps the Triking styling (front) was an influence in the ACE design.
https://thekneeslider.com/ace-cycle-car-from-liberty-motors/Since Liberty sidecars are glass fibre, I can only imagine that the ACE uses it for their body compared to the M3W using aluminium. If that’s the case, then that’s the biggest strike against the ACE for me. Because the Harley is air cooled, the venting on the bonnet sides look fake, as if implying that there is a radiator behind the engine, the knob at the top front with a wing adds to that. Though I suspect that winged cap is functional (oil goes in) where the optional one on the M3W is just for looks. The one piece roll bar looks out of place too, compared to the twin hoop M3W.
Edit add: I also don't like seeing the modern rack and pinion steering with rubber boots and the light bar in front of the engine.
Overall to me, the ACE is a Triking with the rear sides shaved off and with a Harley engine up front instead of the MotoGuzzi. I cannot get over the glass-fibre (fiberglass) body work either when compared to the Morgan. I’m sure the engineering, materials, and construction are first class on the ACE v1.
The ACE v2, looks fun (on a track) and reliable with the full Goldwing drivetrain. As many here do, I prefere a V-Twin out front so the v2 doesn't do anything for me.
