Hello, Mark -

I found a review of the Schwinn 227p recumbent exercise bikes dated 16 Nov 1971:

Are you really asking about a Schwinn 227p recumbent exercise bike you are considering purchasing second hand and want to know how old THAT bike is? If so . . . ask the seller if he / she can tell you how old the bike is.

Or, do you have such a bike and want to know how old it might be? If so, and if you can locate a serial number on the bike, this website may prove helpful:

You can also contact Schwinn directly to find out if they can identify the age of the recumbent bike in question:

Best wishes.

See Assembly Stage 8 - showing to plug in adapter on front of the bike near the base.

If the recumbent digital computer gives you an option of power supply or batteries then you can deduce voltage of the power supply by counting the number of batteries needed times 1.5 (1.5 volts = voltage of AA or AAA battery).
You can deduce typical current by multiplying the number of batteries by: AA = .05 amps or AAA = .01 amps.
Your next issue will be to deduce the polarity. Look at the Schwinn to look for a symbol that will show you polarity. Typically the center of the plug is: + positive and the outer shell is - negative. There are instances where those two are reversed.
If this is all too confusing then Google the recumbent model number to find replacement power supplies ($35 to $45 US).

It is very difficult because there are two main versions of exercise bikes, so I've picket two of each type. If you prefer an upright bike the Schwinn 140 Upright Bike is the best pick, if you're more into recumbent bikes the best option is Nautilus R514 Recumbent Bike, both of them won the 2011 best exercise bikes.
