Actually, the c is for skinny. More or less. It was originally a French size. By their system, the number was roughly the OD of the tire, A was a fat tire, B was medium, and C was skinny. The whole modern sizing thing is a crazy mix up of the remnants of various older systems.
Tire Sizing Systems
EDIT: There are also 700c tubular tires and rims (glue on, not clincher).

Sew ups are what I meant by tubulars. Having had zero experience with them, I THINK both terms mean the same thing. Hopefully somebody will correct if that`s not the case.

I'm planning an electric streamliner similar to this. Project goal will be 40, 40, 40. 40 mph for 40 miles at 40 Whr/ mile (850 MPGeUS)

Tubulars are sew ups from older road race bikes. My 700c clinchers are 32-35 mm wide on my city bike. The latest development is tubeless clincher conversions.

Sendler, you may be surprised that your project bike will be more efficient than projected. The hardest trick may be the putting the foot down at the stop sign. See lots of info at recumbents.com. Tubeless clinchers have half the rolling drag as tube types. The Stan's system home office is here in Horseheads, NY and they do 700c road tires. Please keep me posted.

Sendler, why the motor? If it is a bicycle, then pedal it.
This is one of my commuters:
Still a work in progress.

An electric bike has some advantages when in stop and go city traffic. Western New York is quite hilly. Changes in elevation can be 1000 ft. in 5 miles. We do need to update the electric bicycle laws in New York.
If you get the chance, visit Pete Stull, The Bicycle Man, in Alfred Station, NY for the large selection of recumbent bikes. The National Sailplane Museum is here in Horseheads, NY where you can see streamlining examples.

This is my everyday commuter if it is not raining in the morning. I use it until weather gets too bad/cold. You never know when it starts to rain in here, Estonia. So thats why it has mudguards - they are a-must item in commuter.
It is electric mid-drive. Roundtrip is 31km, and one-way 15.6km takes about 30-33min with average around 28-32km/h. Before converting it to electric hybrid it took 10 minutes more and much more sweat
