PreviewProductRead the SellerTake a good account of the person that is selling you the. Is it the right size for him or her? Could it even be a possibility that this person was the previous owner?Take note of the words the seller is using when describing different aspects of the bike.
Feel free to ask very specific questions about it. If the person owned the bike, they should have no trouble answering these types of questions.You can even do a little research beforehand to help verify if the seller knows what he or she is talking about. Serial NumberEvery bicycle has a unique serial number. To find the number you must look on the underside of the bike, underneath the pedals. The number is engraved on the bottom of the frame.If the number has been scratched off, good chances are the bike has been stolen.If the number has not been scratched off, be sure to write it down.
There are websites with filled with bicycles and their serial numbers.Run the bike’s serial number through some online databases in your country to see if the bike was ever reported stolen.If you are in the United States, check out orIf you are in the United Kingdom, check out. Unusual StickersSometimes will engrave a police number on the cycle, to help track it if stolen.
Keep an eye out for unusually placed stickers on the frame. People will use inconspicuous stickers to cover up these police numbers.
Spray PaintBe weary of it being re-painted. People will spray paint a stolen bicycle to help conceal its identity.
The paint not only hides the model and make of the bike but also the serial numbers and rust.A good indicator that it has been spray painted is to look on the frame. If the frame looks as if it has a bumpy texture in some spots, it was probably spray painted.Look at the areas that are difficult to spray paint.
The areas in which two parts of the frame meet. Damage from ThievesThe first step in stealing a bike is breaking the lock. Thieves are not particularly gentle when breaking locks. Sometimes they will bend the frame for leverage when cracking a lock.When locks are broken off, it can cause damage to the frame or the spokes of the wheel. Keep an eye out for damage in these areas, as it can be an indicator that it has been stolen.
Post-PurchaseAfter you get the used bicycle, feel free to contact your local police department. Explain to them your situation, and have them run your serial number through their local database. It can’t hurt to see if something comes up in their records.
You should also be able to register it in their database in case it gets stolen in the future. I love bikes (can you tell?). I used to race them back when I was younger and had more free time. Now I just ride for pleasure and work on bikes when one of the local bike shops needs an extra hand for the day (or a bike race needs an extra wrench).There aren’t many sites with current bike reviews out there — especially for the beginning rider. It is my goal to fill this gap with accurate reviews and helpful information to make bike buying (and riding!) more enjoyable.–, Blogger, Cyclist, Certified Personal Trainer.
Are all bikes manufactured in the eighties?2. How many welders are there? Is the welder always identified by a single letter?1.
We think all bikes are manufactured in the eighties - you would not believe how hard it was to crack this code - the bikes made in the seventies have totally different serials - which still haven't been deciphered yet2. From what we can tell there were 3 welders all identified by a single letter - their first initial(there are also prefixes for special edition bikes but they are quite rare and can be dealt with on a case to case basis ie T for team rider bike). What I'm not clear about is what they did in October, November or December, as there appears to be only a single digit for the month.HTHBrianThat is what confused us for some time!Following the sequence, purely for illustrations sake, the last December 1981 frame, build sequence 256 welded by Mark Bradshaw bike would be stamped121256Mthen a January 1982 welded by Darrell would be12257DWhen we only had a few frames as reference you could understand our difficulty in establishing their heritageCheersBen. I am afraid I don't follow this fully. If there are two 'versions' of the frame number and each needs to be interpreted differently, then the version should be entered into another field (assuming it's not apparent from the frame number alone).Now I would suggest you sit down with a piece of paper and write down the steps you would take to identify the month and the year without a computer (think of this as writing directions for a stupid but reliable person). Then the actual calculation will become easy to construct - assuming the task is possible in the first place.
Hi Ben, and Welcome to the Forum,I've been toying with your sample data in TextWrangler, and I think it might be possible to do the lion's share of this parsing out using grep patterns in TextWrangler or BBEdit.The real challenge is the Oct - Jan productions, however, I was able to parse out the Dec and Jan example you gave, using a couple of greps. However, the real test would be with real data.Are you trying to breakout this data on bikes you own, bikes you want to purchase, or are you doing this for all of the bikes manufactured by these two?Do you have a complete list of those you want to parse out?If so, why not post it as an attachment to a Reply, so that I can get a better feel for the complete picture?HTHLee Edited September 20, 2010 by Guest. Hi Lee and thanks others for your repliesWhat we are trying to create is a couple of things in one for the enthusiasts of this particular Australian made brand.Firstly a decoder of the number stamped on the framesSecondly an historical archive of the frames themselves including some other aspects such as paint finishes and the likeHere's the breakdown as we established it, in a little greater detailFor the frame stamped 501161D as an example5= May some serials began with 10, 11, or 12 for October, November or December. Eg 110xxxx X0= 1980 they used the last digit of the year & will always be 9,0,1,2,or 3.1161= the serial number of the frame. This can be as short as one digit, ie, 911 for Sept, 1981, frame number 1.D= Darrell Kendell, the man who actually built the frame in the factory.Other code letters used as a suffix areM= Mark Bradley who was a frame welder, a designer, test rider & Factory Team rider.R= Ray Williams. He is currently the state Liberal member for Hawksbury.X= Not currently known but thought to have been used on Factory Team race bikes.Prefix codes were sometimes included and can also be used as qualifiersTF= Team Frame. This was used on the 'Team' models, which was their production race model from December 1979 to August 1981TH= Team Helium.
This was the replacement race frame for the Team & was manufactured from September 1981. It was available until the end of manufacture in 1983. (these also had their own serial numbers starting from 1 - it is thought only 150 of these were made)24. This was seen on the earliest of the 24' Cruiser models & was followed by a one or two digit serial but no date code.C. This was used on later 24' Cruiser models. Very low production numbers but part of the general serial sequence we thinkCR.
This was used on 26' Cruiser models. Same as 24' modelsM. This would indicate the Mountain Bike model that was largely based on the 26' Cruiser frame. I am sorry, but you are only confusing me even more.
If I understand correctly, after removing the prefix and the welder's code you are left with a sequence of digits. I think you have now also narrowed the years to 1979 - 1983. And I believe the serial number cannot start with a zero.Therefore, if the sequence begins with one of these:122123we need something more to tell us what these mean. Everything else should be very easy (unless I am missing something again). I am sorry, but you are only confusing me even more.

I don't care if you write it out as text - as long as it becomes an algorithm (i.e. Something that a stupid machine like a computer can follow blindly, without any judgment calls of its own).-P.S. You can skip the prefix and welder extraction part - these are pretty clear, I think. Start with the following input as being known:FrameNumber - a variable number of digits;Prefix - as per the list of possible prefixes you have provided (incl. '24')Location - a Boolean value, I think? Edited September 21, 2010 by Guest. I don't care if you write it out as text - as long as it becomes an algorithm (i.e.
