The new rear rim setup with Schwalbe rim tape:
I used Schwalbe rim tape on both the front and back. Papamotor users you should take the rim tape off your stock bicycle rim (depending on front or rear hub motor) and use them on the Papamotor hub rim. I noticed the spoke holes left nice little circles on the inner tube when I took apart the stock hub motor rim. Any abrasion from the spoke holes on the inner tube could cause a flat.
I have the new rim on the bike.
I had to make a few small adjustments but everything looks very good. I'll have more pictures later this evening...after dinner and an hour or two of work.
The rear Maxxis Hookworm tire fit just fine. I was sweating bullets for a while.
