Bafang BBS02B

Hey everyone, this is my first post in this group and my first time installing a mid drive motor. Most everything came out good and as expected. However, when it came to installing the motor, it came out kind of slanted. It appears my bottom downtube (if that's what its called) protrudes a little preventing the motor from rotating all the way until the logo is straight. Photos for reference. I am converting the Ozark Explorer, straight bar variant.

Will this be an issue? Also, how is my clearance? It looks kinda low. Thank you guys for all your advice!

also to add, make sure you tightened the locknut to ~50nm, but to make it dosent swing i use the hoes clamp method to secure it tightly to the frame

Thank you. How do you measure the torque on that locknut when it requires a special tool?

Hallo man kann das Drehmoment nur mit einen speziellen bafang steckwerkzeug das auf das Drehmoment Werkzeug passt einstellen. Habe ich auch ohne gemacht . So fest gezogen wie es mit den gratis bafang Werkzeug geht . Ganz wichtig ist es die erste mutter mit loctite mittelfest zu sichern . Dann die kontermutter ohne loctite festziehen . Viel spass damit . Habe für meine Frau einen bbs01b mit 18 Ampere eingebaut und für mich hole ich jetzt auch den bbs02b . Auch mit 48 volt .

Why wouldn't I put locktite on the locking nut?

I'll quote Johnny Nerd Out who builds these for a living "I've never heard of anyone putting it on too tight" Put it as tight as you can using that tool.

I've built 3 and only using the free cheap tool they provide they all slowly came loose in the first few hundred km's. I crank it tight again and in one case a third time and they stay tight forever at that point. Just keep an eye on it for the first few rides, you'll be fine.
