I have a Health Stream recumbent exercise bike - it is now making a very loud noise and appears to be scraping a bit. I think it is ~8-10 years old and has never been serviced. Do these bikes need to be oiled and if so where on the bike? I am a 60 yo partially disabled man who needs to exercise on such a bike - it is in good condition and has been used reguarly for years. Are you able to provide me with advice? I live in Australia.

the Healthstream MB303 recumbent bike requires a power supply with an input voltage of 90-132VAC, 50-60Hz and an output voltage of 9VDC, 1.5A.

You can purchase a replacement power adapter with these specifications from Schwinn's official website for $18.99

Question edited for clarity, full make model (what it is), and wrong type of peddle (drugs) / pedal (a bike).
Question moved from Cars and Trucks to Exercise Bike category.

That noise is normally caused by adjustable bearings that need tightening up. There is help in the link.

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:

If you have not used your machine in about a year, most likely the battery is dead. You can find most of the parts you may need here:

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.

Recumbent bike works best for elderly people with back and hip problems because of the relaxed position and the angle that put's less pressure on those areas. Upright exercise bike works on more areas than the recumbent bikes including the lower abdominal muscles.

There are most likely some sort of bearings inside the wheel hub that are causing this.
