( Updated) TSDZ2 build is about to commence! Scratch The Tsdz2 I am going with a BBso2

Jimmy, maybe I'm not following your question properly, but I don't see any way of predicting chain line issues for sure prior to the actual install of the motor.

I am wondering if I can just put the Lekkie on instead of the stock chain ring with the use of spacers.

 

[Gionnirocket]

So I could use one even without chain line issues? I would not want to order one if I can't use it lol. I got the kit from JohnnyNerdout and it will come with eighter 44 or 46t depending on inventory. I am guessing 46 or 48 for the riding I will be doing.

From what I remember the stock Bafang chain ring has about a 5mm offset towards the frame... The BlingRing has I believe a 9mm. So you should be able to know the chainline implications by mounting the bafang stock ring if the motor is fitted to the frame.
Spacers are also available to compensate the BlingRing offset... But for the reasons stated above I stayed with the stock ring as alignment was near perfect.

Read the offset info

Premium CNC Bling Ring - Bafang Chainring BBS01 BBS02 - 46T - Lekkie

The Lekkie Bling Ring - Bafang Chainring for the Bafang mid drive motors are being celebrated as the #1 performance upgrade for the BBS systems. The original, and still the best. Bling Ring 01/02 is designed specifically for the Bafang BBS01 and BBS02 motors. Is this compatible with your motor...

Well the Bbso2, gearshift sensor and spacers arrived today. No going back now! Johnny Nerdout even threw in a headlight for free which was nice.
Program cable is on the way and now I am hunting for a good battery. I am thinking about a 48v 17ah. Still playing with the idea of an IGH since I forget to downshift when stopping.

 

[Gionnirocket]

I passed on the shift sensor and really haven't had any issues as I've always micro_paused pedaling before a shift. That said, many use it and seem to be happy.
When stopping and forgetting to downshift you can. . .
When off the bike, lean the rear tire off the ground with the kickstand and use walk mode to move the drive train to get back to a lower gear.
If still on the bike I drop to PAS 1 and then use a series of shift and then half rotation of the pedals... repeating until I am in the desired gear. If I need assistance from the start I use modest throttle to get rolling and then the former.

If there is any extra wear on my drivetrain, I haven't noticed it as chains seem to be lasting just as long as before adding the BBSO2B.
My settings in general are tame and I I'm doing as much work as the motor when riding. Occasionally I do get aggressive with the motor just because it's fun to feel like superman on a nice day

For a battery... contact @Jenny Mao as she has a wide variety of battery options and has a good reputation here on EBR.

On the bold, this is my plan as well. I believe though, the BBSHD and Ultra being the giant torque monsters they are, are more forgiving when it comes to this sort of thing. FWIW

I used this to determine chain line.

D is Bottom Bracket option of your motor (68mm is typical)
F is chain line from center of Bottom Bracket

BBSHD

No need to worry. I beat the crap out of mine. Used by hundreds of pedicabs. Believe me those employees are BRUTAL. Once Bafang beefed up the rotor shaft they’re really quite tough. Many are bullet proof. I road one for two years full throttle in 5th gear never using to other 6. Stop and go. Around 2600 miles. Opened greased and sold with full disclosure.

 

[m@Robertson]

On the gear sensor yea/nay... I have BBSHD'd bikes with them and without. You don't need them. I have two of them in my parts pile and have never felt the need to install them. Just not worth the effort when I have automatic learned behavior now that makes them unnecessary.

I do have one in my parts pile for the bike I am building right now. If I can plug it in without unnecessary gymnastics I will, but I won't feel bad if I can't.

I put a lot more detail here:

BBS02 and BBSHD: Do I want a gear sensor?

This is a common question on BBSHD and BBS02 motors, so I thought I would write up a quick post and describe what can be done, and what I do.

6 of the Beta from my Endless-sphere distribution 7 years ago and 3-4 of Enoura (sp?) copied rip offs. I did have a few customers save their replacement IGH using them on BBSHD. More an IGH model issue IME.

 

[tomjasz]

I’m sorry I just read you’re going BBS02. Old eyes muddled brain. I have a new BBS01B 500W and I will NOT ride it like a BBSHD.

I never thought of it from that angle but it makes perfect sense. Actually with all the attention that issue gets I'm surprised its not brought up as a de facto easy solution.
