My R Martin EVD LFP arrived yesterday. I'm starting this thread to describe my experience.
Fedex Freight did a nice job on the delivery, and the box had minimal external damage. The box lifted off to reveal a well-padded scooter sitting on a metal pallet. The top of the pallet unbolted, and then several wire tie-downs needed to be removed. The hard part was lifting the scooter off the pallet to the side, front first then rear. It's a 2-man job, at a minimum. (I don't want to think about the people who didn't get the lithium batteries, since that is supposed to make the bike about 100lbs heavier.)
Assembly was pretty easy, there were only 3 parts not already in place: the windshield, the throttle assembly, and the rear side panel. Both tires were seriously overinflated, I dropped them from ~47 psi to the recommended 33. Batteries were charged, as best I can tell. I noticed 3 minor blemishes on the plastic pieces due to shipping damage, but I'm not sure it's even worth asking for replacement parts.
(I've got pictures, they'll get posted later today.)
I took my first ride last night, a couple quick loops around the neighborhood. I'm used to riding a Honda Silverwing 600cc scooter, so most of my impressions are relative to it. The EVD is much quieter, but not completely silent: there is a bit of a whirring noise. I do get much more wind noise than I'm used to, but I have a large windshield on the Silverwing. I easily hit speeds in the 45-50mph range, I'll check the top speed with a GPS in the next couple of days. The EVD is rated at 4hp, which is much less than the Silverwing's 50hp, but it's also a much lighter bike. The brakes on the EVD are good, quickly bringing me to a stop with minimal fuss.
I need to adjust the headlights down a bit, the low beams are about 5 degrees too high, and the high beams mostly illuminate the trees. I couldn't feel an adjustment screw when I stuck my hand inside the fairing, but I'll open it up this afternoon and look closer. Good lighting is important to me, so I'll be looking at these more closely later.
