Well, I have 2. My 83-year-old Father Bought an FLX F5 Trail, but he barely rode it. So I took it over and rode it a few hundred miles. It was great on the road, but anywhere else it was so uncomfortable. It had the touring package which is ok. The FLX had a Shimano Deore 6100 1x10, & magura MT5E brakes which are what really shined for such a cheap Ebike. The M600 engine was great, but 125miles in the torque sensor went, & FLX never replied to our e-mails. 4 weeks later, and over a dozen e-mails, they say they are shipping out new motor, & Harness for us. But Both never showed, so we ordered a Torque sensor on greenebikekit.com or something like that and fixed it ourselves. It's run perfectly ever since, though it has a lot of upgrades on it now. It's still a pretty basic Hardtail touring bike, with thin 2.4 tires which I didn't care for.
Now I own a LUNA X2 Ludicrous V2, which I received on 08/17/2022 & I love outperforms just about anything on the trail, & I road 30 miles in PAS3 with power at 1500watts peak & PAS at 86% & when I got home I still had 31% battery left, but she was hot at 94degrees. The last climb was 2 miles which is as steep as it gets for roads. So I had to take it slow. I ride with my Brother who owns s Bakcou Mule Ultra M620 engine and that thing is a beast. It never stops putting out power. Downhill, I'd be free peddling 0 resistance & he is still gaining speed. The mule is 80lb's my X2 is 54lbs, with all the upgrades I'm around 51-52lbs now. If I was to buy a gravel, enduro track, or ROAD bike with an Ultra motor I'd buy either LUNA Z1(ship engine out during offseason to watt wagons for Archon X1 installation.) Or If I am really well off, & had no really money limit. I'd buy the Watt Wagons Hydra Archon X1 Build. I'd still want to own my X2 ludicrous V2, & the HPC Revolution AT with the Rohloff if I had unlimited funds.
Attached are Photos of my X2 Ludicrous 2500watt M600 by Luna Cycles, & all the upgrades I've made over time. Most recent was the RaceFace Chainring.
If Anyone has any advice for me. Please let me know.
Current X2 setup-
BAR=31.8mm Originally 810MM, but was cut to 762mm
Stem-Truvativ Atmos 7K 70mm +6 Degree
Dropper Post-PNW Components 170mm Rainier Gen 3 w/Travel Adjust
Grips-Ergon GA3 standard size
Chainring-Purple RaceFace Atlas 38T Chainring
Pedals-OneUp Oil Slick 1 Size.
Planned Upgrades to come- Raceface ARC35 or ARC40 Offset HD Rims, w/ Industry 9 Hydra hubs(J Spoke, XD or Microspline) May Upgrade drivetrain to GX Eagle setup(Run XD driver), or I may decide to go to the easier to shift & more comfortable Shimano XT Deore 8100, but only after the warranty expires or a part goes bad can I change the drivetrain, so HUB must be able to swap the drivers from HG+ to XD or MicroSpline. Heard a ton about Shimano LinkGlide, but so far the power on this Tuned M600 isn't comparable to the Ultra motor. Nor can it climb faster than ULTRA. If the salesman said to me, that the Z1 will climb and go faster on the throttle than the m600 up & down hill which is the actual fact. I'd have a Z1 right now, & bought the X2 next year. But I was misinformed, by accident I'm sure. So I will own a third E-Bike Eventually. No matter what, I'd own an X2 for downhill E-bike and higher-difficulty trails.
Love the X2 Ludicrous but when riding with people with ULTRA motors, or cyclones, I just can't keep up.
). Over the past few years I’ve added the bling which has probably cost me thousands of $. Let’s just say they all knew me by name at the LBS’s. 
. Soon after I added a his/hers Powerfly 5’s after I sold the road and 2 gravel bikes. Most of this happened pre-pandemic but during the eBike craziness.
