I've been there, done that RIP tandem
Ohhhhh, oh! So sorry, Pete (Il Padrone).
The Spectre of this hovers there, awaiting all of us who transport the bike outside the car. I've seen placards that suction-cup to the inside of the windshield or hook to the back-side of the rearview mirror as reminders, but friends who use them say they soon become habituated and ignore them. As one friend told me, "The crunch of the bike against the roof of the bank drive-through was a dandy reminder of limited clearance!" As he told the bank teller, "I may need to withdraw a few more funds now!". Poor guy, the bikes were covered under his homeowner's insurance policy, but the damage to the bank's drive-through canopy came out of his car insurance...and resulted in a rate increase. As he later said, "I'm stimulating the economy -- single-handedly!"
Boy, getting the Nomad inside my '89 Honda Civic hatchback would be a challenge! I did manage to get my '70 Raleigh Gran Sports inside it once, after removing the front wheel. In theory, it
should be possible with the Nomad. I recently installed a receiver-type trailer hitch and have a plug-in bike rack for it, but the usual concerns apply and I think the support arms are a bit wide for the Nomad. Last time I transported a bike by car was in 1980, and that was not an entirely happy experience. Washington State's Mt. St. Helens had just erupted, and by the time I arrived home, the bike was coated in corrosive ash caught in and stirred by the car's wake.
Best,
Dan. (...who is going to have to give it a try, sooner or later)
