My wife and I chug around on our hybrids, often running errands with groceries in the saddle bags, and joke about running down and passing the TDF-kitted out lean guys on their unobtanium-framed road bikes who whizz by us.
Do largely to a balky knee of mine we've decided to add electric-assist to our bikes, and once they're installed I'm REALLY looking forward to actually passing one of those guys on a hill.
Electric-assist kit: $1,000
Look on racer-bike guy's face: Priceless
