I saw my first E-Bike kit on Amazon several years ago (2019) and it seeded the thought in the back of my mind that I might do a DIY build one day for fun.
Around June of 2020, I heard a David Lee Roth podcast wherein he extolled the virtues of his E-Bike. The line that stuck with me went something like this.
"The best part of Yoga is being done with Yoga, the best part of doing calisthenics is being done with calisthenics. The best part of riding an E-bike?, riding the E-bike!" That month I had a family vacation planned with my wife and two of our adult children to Monterey CA. We rented E-Bikes in Monterey and took a ride along the beach, 17-Mile Drive along Pebble Beach and the Cali Coast. That ride would have sucked due to a 10mph headwind along the beach, but the E-Bike made it a breeze (no pun intended). I became convinced E-Bikes for my wife and I would be a good investment for our health and for fun. It was Sept 20', the height of the COVID Pandemic and all bikes were in short supply, especially E-bikes. Only Aventon and Ride1UP had bikes in stock within my price and requirements range. I ordered two Aventon Level Step Throughs. When they arrived a week later I was impressed and took to riding daily along the 60 miles of paved and well manicured bike trails around my home. While riding I quickly realized that I had a penchant for diverting "off-road" and "attacking" the many grassy banks, valleys, and wooded areas adjacent to the trails, at high speed. My Aventon Level would not suffice (lack of rear suspension) and was not built for what I decided I really wanted to do. I wanted to be able to go anywhere I wanted to, on my bike. In December of 2020, I took the plunge and ordered a $260 Mongoose Fat-Bike made of steel from Walmart, and a Bafang BBSHD kit from Luna Cycle. You can read my DIY build thread here. I took a chance, knowing zilch about fat-bikes, and knowing nothing about E-Bike motors, kits, mid-drives, brakes, or bicycle mechanics in general. I am mechanically inclined and confident that given the right tools, I can build, or rebuild anything.

The Fat-Bike build was a great learning experience and I rode her as hard as she would take, and I love her. She still has the original super-cheap-ass cable brakes that will stop her in the most dire of circumstances. I added a cheap $150 front air fork, a SunTour suspension seat post, metal fenders, and a Shimano type hub, Advent 9 speed shifter/derailleur, 11-42 Advent cassette, with a Luna 42T chainring. She will go anywhere, and climb anything. I put 3,300 very hard miles on her since March of 2021, and 1200 miles on my Aventon Level.

I wanted more. I wanted a lighter, hotter, more capable bike with torque sensing and rear suspension. After a lot of research, reading threads here on EBR, many reviews, and threads on Endless Sphere, I decided to purchase a
Carbon Fiber Mid-Drive Z1 from Luna Cycle. I love my new Z1. It's very, powerful, lightweight, nimble, and the suspension is incredibly smooth. I've had much success dealing with Luna Cycle. They've been very helpful on my BBSHD build, Tech support, and a warranty claim on my display. I opted not to go with the the Luna X2, which is essentially the same bike except the Bafang mid-drive motor on the X2 is a less robust version of the Ultra-Mag, and it uses the CANBUS communication protocol rather than UART protocol. CANBUS is proprietary locked system. The Z1 Ultra Mag motor uses the UART protocol which makes it easy to program the stock controller and upgrade the controller to a GRIN Tech controller in the future.

I've learned a lot on this journey and welcome questions. ~Tom

Expensive learning curve but you got there. I started in 2016 and still have that original bike as my e bike. I replaced the BBSHD motor core at around 13,000 miles. I started with a Bike's Direct Titanium Night Train Bullet. A full fatty and built up from there. Expensive learning curve as well.
I found that I am no longer able to safely do hard core single track and started looking for something else. I started touring and quickly ran into range anxiety. I currently have four batteries in parallel on the bike for 2,540 Wh of power and don't sweat the range anxiety very often now. Had to resolve the saddle issue before adding more batteries. I am currently eyeing a custom build cargo for extensive remote dirt touring.
 
Yes, it was an expensive learning curve :) Funny, I was looking at all four bikes after riding yesterday, and smiling when I was thinking about my hesitation regarding my initial $3,200 investment for my first two Aventons. I never would have imagined that I would end up spending $11,000+! My wife and I usually invite friends over to go riding with us, so all of the bikes do get used often. I'm much healthier than I was before I started this journey, and I sleep better than I ever did. I picked up a new friend whom I ride with about four times a week, so the investment was well worth it.

Sounds like you have a lot of juice on that bike now, no range anxiety! I ordered a second battery for the Z1 for the same reason. It can be mounted on the downtube. Shoot me a pic of your rig. I gotta see how you mounted all that juice. Are they wired in parallel or are you using any kind device to connect them. I've been looking at this: DATEex2 Parallel Battery Adapter
 
Nicely done Tom!
'Been an education for me too. I've been retired for a while now (watching my expenditures closely), so I think of what it cost me as a hobby, that way I don't have to justify it! Even so, if I did have to justify what I have wrapped up in this "education", it would be easily justified. At 71, it still gets me off my butt at least once a day, AND, I just flat enjoy it! Too, the fact I've been able to share some of that education with those just coming up to speed, has hopefully saved them from some of my lessons learned the hard way. -Al

Thanks Bud! Yes, I can attest that the hobby is definitely justifiable. know that you have been very helpful to myself and many e-bikers on the forum. Your advice on the KT Controller and Display made my wife very happy with her Aventon Level. These bikes really do do make me want to get out every day and just have fun! The exercise is a bonus. I get out almost every day, year round and really miss riding when I have to go a day or two without riding.
 
The evolution or path? First bike was a Rad Rover. Second was a Specialized Turbo Levo.Third and current bike is a Specialized Vado SL 5.0 Wife's Specialized Como. Lots of leaning curve but a great hobby,
 
My tail started only months ago... Anyone who knows me knows I live in a constant mid life crisis... Hot rods, 4×4 trucks, snowmobiles, go-kart, ect... No real big budget stuff everything something I built myself over time...
So a few months ago I get this bug in me wanting my 24" childhood BMX...
As I searched, my original JMC is far to expensive to recreate (if I could find one).. so I start looking at other options.. SE racing has the fovelflyer which was from my day..
THEN I stumbled upon the soul fast e-bikes... Even though I live in one of the most bike friendly cities in the country there's nothing like this... My wife and I made a road trip... 2700 miles.. we visited family and what the heck Vegas and Reno on the way home. But the trip centered in Mesa Arizona. We met the owner Jim Decker and he gave us a tour of the shop and test ride ..
I was sold... Everything I was personally looking for and my wife got one as well.. my wife didn't make it to the end of the block before she got her first "nice bike"... Me, I'm very happy.. support has been spot on for the couple of very minor issues and it is everything I expected it to be..
Only picture is of my wife on a local bike path with Mt. Hood in the back ground.. so I'm posting internet pictures... These bikes are fast...

^^^I don't know what it is when I look at these pictures on the internet it makes the bikes look much smaller than they actually are. I'm 6 ft plus and my bike is very substantial for me... Mine's the 26-in and my wife's is the 24-in. I have a friend who's about 5'5 and would not recommend my bike to him...

Yes, power is addictive. I've broke my ribs twice in the last 13 months, so in order to insure that I have "many more miles and bikes", I've upped my game on the protection gear.
Troy Lee Vest, Elbow Pads, Knee Pads, along with the helmet!

Tom,
Which trails you riding in NOVA? Last year I rode Fountainhead Green, Blue and Black trails. Really fun on a Luna X2.

X2 is a really nice bike! I doubled my battery to 35Ah, really having fun on the Z1.
Fountain Head is a great staple. Let me know when you are headed out towards Ashburn Va area. We can hit some local wooded trails in my area, or meet in Reston and do Lake Fairfax MTB trails.
Wakefield Park in Annandale just off 495.
Lake Fairfax Park, Reston. Great trails in the woods, a section strictly for air jump practice (5ft-25ft). Host to several competitions each year.
Rolling Ridge, off Route 7, just outside of Bluemont on the Appalachian Trail.
Virginia Freedom Center, outside of Lucketts. small but well maintained.
The Potomac Heritage Trail. Scenic, less technical wooded trail runs along the Potomac River from Great Falls to Leesburg.

Willowsford Farm in Brambleton 12+ miles of well maintained wooded trails.

Willowsford Grange in Aldie. 10+ miles wooded trails.

`If you don't mind me asking, how much did that set you back total? This is something i have been think of adding to my RX.
$2,075 all in, including a new rim. I understand your usage of the phrase "set you back", but I am convinced the expenditure moved me forward. It has added to my joy of riding immensely, it will reduce my long term maintenance time and cost. The investment will pay dividends well into the future. I'm sure will own the hub for life, and very likely transfer it to a new bike should I ever need one. YMMV.

I was hoping for something closer to the $1500, kinda steep but i feel like this is really the one thing keeping my bike from being a perfect fit for me!

The QR Axles and axle bolt versions can be had for $1,400-$1,500.
