hi, my name is mike, I live in Salem or, & got bit by the motored bike bug. it started with trying to get a weed-eater engine to propel a spare bike i had lying around. i have since ordered a gebe kit & am waiting for my early Christmas present. lots of ??? to follow. my first is, what is a good choice for a durable rear tire in 26" mtb style? 50/50 road-trail. I'm mainly after puncture resistance. thanks for any advice.
