Looking for a new bike under 500$ for first build. Mid mount. I am confused about bb sizing. I do not want to buy wrong bike. Example gravity bullseye monster specs 100mm/144mm vp cartridge. Gravity deadeye specs102.5 x 145 BC63L cartridge. Which number is width and diameter or will they not work. Any know available fat bike suggestions would be appreciated..Thanks
Do you know what mid drive system you want to go with? Most of the mid drive conversions I've seen replace your existing BB.
Largest BB shell you can do is 100mm
That system will replace your existing bottom bracket.

So look for a frame that list the BB shell as 100mm or uses a 100mm BB.

Just so you know that kit will more than double (if not triple) the cost of a $500 bike when you factor in the motor kit, charger, batteries and battery shipping cost. Then depending on the rear cog you might need to spend $100 to change out the front chain ring.

I highly suggest you buy the tools from Luna Cycles for installation, it can be done without but is much easier with.
