I decided to build a BBSO2 into a cruiser frame. Looking at the Raleigh website I found they were selling discontinued or maybe last years model Retroglide 7 bikes for a good price. I didn't like the color so a trip to Home Depot scored me a rattle can of flat black paint and it painted up very nice. Flat black is great also because it is so easy to touch up it's ridiculous! Since the original paint job was pristine I merely roughed it up a bit with some steel wool so the new paint would have something to key into.
I knew I had a problem when I realized that the bottom bracket was the old fashioned one piece crank design and the BBSO2 would never fit in its 2 inch diameter maw. I thought I was sunk when I soon found out that although there are adaptors available to reduce the bottom bracket to the proper diameter, I would need the new opening to be off center. The BBSO2 has only about 12 mm of space between its axle and the motor housing.
Lucky for me after a ton of searching I was able to find a guy selling on Ebay and offset adaptor set for another mid drive motor called the TSDZ. The axle diameter was less on his motor though but he kindly made one to fit the Bafang after I sent him my measurement! This fit like a dream and I thought it was so important for others to know that I started a thread about it here https://electricbike.com/forum/forum...r-bmx-style-bb

Once that problem was solved the rest went together without a hitch. The BBSO2 unit installed as easy as pie. The adaptor did increase the bottom bracket width from 68 to 73 mm but a few washers on the locking plate bolts took care of that just fine. Then I gave the motor a spray of the flat black too just to stealth it up (sorry about erasing you name from the motor Luna!)
Wiring was especially easy with the plug and play connectors. This is a pretty big bike but Luna came to the rescue with a plug and play extension of the main harness which made the whole process trivial.
I went with the Lekkie Bling ring 42T, its offset gave me a perfect chain line, the Bafang crank would have worked but it was just butt ugly.
I had an unused rear rack laying around and based on an idea I got from some gas powered bikes I had seen, I installed the rack and ordered 2 inexpensive motorcycle tool bags found on Amazon (they normally attach to the front fork of a motorcycle). A perfect place to hide a Luna mini battery or two!
I also replaced the stock seat with something I thought went with the style of the bike.
I am extremely happy with the way it turned out!
By the way, the BBSO2, Bling Ring , and battery all purchased from Luna!
