Best Answer: The HA stands for Hawthorne, or the MW brand of bikes. Most Hawthornes were built by Murray Ohio and it looks as though yours was built in 1977.

Hawthorne was a brand of Montgomery Ward stores.Most Hawthorne bicycles were manufactured by the Cleveland Welding Company or H.P. Snyder (makers of Rollfast bicycles). While Montgomery Ward did not actually manufacture the bicycles that they sold, they did commission some unique designs that were exclusive to their stores. Vintage 1950's Montgomery Wards Hawthorne balloon tire bicycle bike black. Combine that with the serial number, 75EH, give us a date in the mid '50's.

If you search carefully the frame may be stamped with the date, looking like 5-77 (for March 1977 for example). No value to speak of, it would be a bad weather bike for me, and perhaps a 'no worries' commuter for a college kid. If it got stolen there would be nothing to worry about. They are readily available in good shape at garage sales and flea markets for maybe $20 or so.

If it's a 60's/70's Hawthorne bike then they were made by H.P. Snyder who also made Rollfast bicycles which had the same frame or if it's an earlier bike it would be made by Cleveland Welding Company. If I had a picture then I could help you more, some members at The Classic and Antique Bicycle Exchange can tell you the info you need by looking at their catalogs. Some of them have Hawthorne's but don't forget pictures along with the serial number. Edit: Rollfast 1960's Hawthorne's 1960's Murray never did made Hawthorne's but understandable to make that mistake because the sprocket looks similar, the difference of Murray & H.P.

Best Answer: Well, lets take this a step at a time. 5 digit zip codes began on July 1, 1963, so your bike is older than that. According to most historical accounts the Hawthorne Bicycle was a distributed by Montgomery Ward from 1934-1960 through their stores and catalog sales. These bikes were mainly produced by the Cleveland Welding Company. I am also aware that the Hawthorne name was brought back and used in the 1970s and at that time were made by Murray Ohio and some other companies such as Puch.

Soooo, the next best option to definitively date your bike is to take many detailed pictures of it (assuming it hasn't been repainted (many have- with house paint:::yuck:::) and post them so we can actually SEE the bike. Regarding value, it is all over the place but don't get your hopes up as it is probably worth more as scrap than as a collectors piece.

For the best answers, search on this site Well, later Hawthornes were made for Sears by Huffy or Murray Ohio. Both manufacturers stamped the date (month and year) on the frames- Huffy usually used the typical month-year numbers on the bottom of the bottom bracket while Murray usually stamped the first and 3rd letter of the month and the 2 digit year on the seat tube right under the top tube (or where it might have been if it were a mens model). This is by NO MEANS universal and I've seen Murrays and Huffys with this info in all sorts of places. Just look for something on the frame that resembles a month and year and you will probably have your answer. • Tell us some more • Upload in Progress • Upload failed.
