I think I have a bike problem

[Mr. Monkeyarms]

First bike looks like Snyder made middleweight from early-mid 60's.

A 54 Cleveland Welding Roadmaster.

A Schwinn that someone knows the year it was stamped.

Red one is late 50's-mid 60's Murray made bike.

Can't help with the Rollfast. Sorry.

The second one (side shots) Schwinn that brake bridge should give it to someone (heavy duty?)

Schwinn frame looks like a middleweight to me.

Schwinn frame looks like a middleweight to me.

Checking the serial number against the reference thread, it looks like "P24015" dates to Feb. 1955, so it could have been a balloon Jaguar, but more likely a middleweight. I can't tell for sure.

The first bike is Snyder built, '65. The Rollfast is also Snyder, '53.
