Hello, I am new to ebikes; got a million questions. I am in the USA. Dollars count here, so I am thinking I might build up a thrift-store bike. I would like a mid-drive set-up with freewheel. I can see the mid-drive will replace the usual pedal crank. After the pedal crank is gone, I will be left with an empty hole in the frame. These frame openings will be different sizes on different bikes. How wide (long) should that frame tube be (between the pedals), where the mid-drive fits? What inside diameter should this frame tube be? By what names do you call these frame dimensions? Will the mid-drive use any threads now in the frame tube, or does it mount with adapters? I would guess that some mid-drive kits will fit more stray bikes than others, so any recommendations? TIA.
