I arranged the slack in my wire harness so I can change a tire or tube without unplugging the motor. Just cut some wire ties & flip the wheel around while the bike is on handlebars & seat. Tell me again how bad messy external wiring looks on diy conversion bikes? How great hidden wiring is?
I wore out the $26 Kenda Smoke knobbies without any flats, ~2500 miles. Tell me again about flat proof tires. Couldn't buy Kenda anymore, out of stock everywhere, so bought Panaracer. Got 3 miles out of that tire before it went flat. Hole in the tube sidewall, couldn't find a mating hazard.
Sometimes Kendas had exposed metal core, which I painted with bead sealant. Very long lasting $26 tire, though.
When the new Panaracer flatted on me, I tried to reactivate my old MTB so I could ride it to the bike shop and buy 2 tires locally. Slime in the tubes wouldn't allow me to pump up the tires. No more Slime.
LBS had in stock Giant knobby tires for $26. 60 miles down, so far so good.
