What bottom bracket fits this Mongoose fat/tall bike?
I built a tall bike based on a Mongoose fat tire bike, but I don’t know the exact model. I’m trying to figure out what bottom bracket fits it, ideally a sealed-bearing BB to improve reliability.
Original bike/frame: https://www.karrotmarket.com/buy-sell/3id5d7sge3rs/?srsltid=AfmBOoq932rnoXASGd_Y5XQcgCjP5rw7Lgt6avfL4cKlxGkNHLJSSRHb
The BB shell looks close to:
- ~4 cm diameter / ~1.57 in
- 11+ cm wide / 4.33+ in / 110mm+
Attached are photos with measurements. I googled common fat tire BB sizes, but nothing seems to match. Please help me identify the BB!
