First Ride on my DIY Titanium eMTB

[SOB]

My first ride on my custom mtb (now a custom eMTB) was ~32 miles and over 4000' of elevation gain, on an 11Ah battery. It was marvelous. The Bafang mid drive motor performed perfectly and assisted me on a ride I could not have accomplished on leg power alone.
Here is a video I made of my experience (my first real uploaded video).

Your chainline probably sucks with that chainring. Expect pretty low chainlife
You might consider reprograming your controller to have smaller power increases at the low end and bigger jumps at the high end. I comes from the factory with 10% increases in power. I programed the first jump at 8% and the next three at 5% jumps and then went to 10% for two jumps and then much higher for the remaining 3 power increases. The smaller increases at the lower end provide much more versatility in powering off or on road.
I powered at titanium fat bike with 52 volt BBSHD drive. Have 52 volt 49 amp hour battery

Funny you mention that. I wanted to reprogram my controller, but unfortunately I do not own a computer (chrome book only) so I am unable to do this until I can borrow one. I do have the chain-line set so that my best line is in the middle of my cassette as this is where I spend the most time. Still, I look forward to reprogramming soon (otherwise I wasted a several bucks on the programming cable). In the meantime, I carry a spare chain etc. with me when I ride.

So whisper quiet and smooth! I love that motor!

I had several Ti bikes bitd including a fs one, all 29"rs of course. That Carver is a beaut and kudos for keeping it on the trail.

I DIY'd my first similar effort 4 years ago, albeit with a TSDZ2 system, and although I have switched it around onto different bikes in the shed some, the way I roll to this day because as I think you concluded with your build you don't have to go to the bike shop and buy the newest stuff to get out there and have as much of a good time as you want especially if you have some experience wrenching on bikes.

BTW I had issues stuffing my shark style battery similar to yours in my Alu FS frame I currently have set up. What I ended up doing was just using the lower mounting bolt and using it to pivot the battery enough to remove it. I use a strap on the upper end while under way and although it was one of those "I guess I'll see if this works" it actually does although I do leave the battery on the bike most of the time. When I do take it off I check the bolt and it seems fine and doesn't come loose but I do use blue loctite on it which I would in any case even with 2 bolts. I ride mainly rough trails here in the PNW too.
