Hi everyone - new to forum. Just picked up a used Babboe City cargo bike. Love it, though it's a struggle going up hills when I'm carrying a load. Really looking to add a mid-drive unit to it, but looking for advice on the build in terms of what works for a motor. Also looking a for a build that can be installed without too much alterations to the bike and can be removed if needed if I need to re-sell the bike. Not looking for crazy speed, just enough pedal assist with hills & when I'm carrying a load.

I've looked at bit at the Bafang BBSHD motor, and recently learned about the TongSheng TSDZ2.
* I suspect the bottom bracket is 68mm, however, it looks like there's a "spine" along the cross-tube all the way to the bottom bracket -- is this going to get in the way of a mid-drive?
* Specs mention the bottom bracket is Shimano Cartridge Sealed https://www.fourthfloordistribution.com/products/city
* The chainring is a 33T, and there's a 7 speed Shimano Nexus IGH in the rear wheel (also has a full chain guard, that I would love to keep if at all possible)
* Existing crank arms are 170mm.
* Brakes are Shimano IM-40 Roller Brakes (hoping to not have to upgrade these if possible?).
Any and all suggestions & pointers welcome. I've looked for other builds but haven't found a similar one yet.
Thanks!
