Most BMX bicycles have a serial number stamped on the frame, which is the biggest and most important part of the bike. Depending on the brand and model of your BMX bike, the serial number used to ID the bike can be on different parts of the frame. A serial number located on a rear drop out. Some BMX bikes and a few Schwinn bicycles place the serial on the rear dropout. On older Schwinns there are numbers stamped on both the drive side and non-drive side rear dropouts; the one on the non-drive side dropout is the serial number. Some bikes have multiple serial numbers.
Serial numbers All bikes all have unique serial numbers. Most bicycles have their serial number engraved beneath their bottom bracket, but sometimes serial numbers are found in other places. Here are some examples of where and what to look for: • The bottom bracket (where serial numbers are typically located) is circled. • A serial number on the underside of a bottom bracket.
• Another serial number beneath the bottom bracket, aligned parallel to the frame. • Some Schwinn bicycles have the unique identifying number on their head tube (which is on the front of the bike). • A serial number located on a rear drop out. Some BMX bikes and a few Schwinn bicycles place the serial on the rear dropout. On older Schwinns there are numbers stamped on both the drive side and non-drive side rear dropouts; the one on the non-drive side dropout is the serial number.
• Some bikes have multiple serial numbers. When adding a bike to the Index, it's best to enter all the groups of numbers and letters separated by spaces.
Hopefully you can find the serial number on the bicycle you're looking at, email if you're having trouble.
So I purchased an old abused DB. I believe it was created by Dr. Frankenstein himself, as none of the parts appear to be original except cranks, chain, and sprocket. The local villagers abused it and left it to die on the side of someone’s house, according to the house painter that came into possession of it.
FYI I have never restored a bike before, but I always wanted one as a kid. I guess I finally got my chance. Before I proceed with the direction I want to go, I want to be sure of the year and model. The bike measures at 18.5 and the serial number is 3×1110. The sticker kind of creates confusion for me because it is not like any I have seen on the web. It has a diamond with the D & the B on top of each other instead of horizontal or side by side. Another question I have relates to handlebars.
In a nut shell, I would highly recommend this company for it's efficient no nonsense approach to doing business. Eddie-Dublin' Eddie - Ireland 'good good good, very perfect suppulier. Richard Ng'ang'a - Kenya 'Got Volvo and Scania parts and Service catalogs from these guys and although I was a bit apprehensive at the time, I have to say I was amazed at how quickly and professionally they had me up and running. They accepted paypal so I knew my money was safe unlike with other companies offering similar services. Thanks guys, I will be back for more and the future.
Did they stamp them? Because the bars I have are unstamped. The stem is not stamped either. I will be searching for a front fork. Does the particular year matter and who made the fork for this bike? If you know of one up for grabs point them my way.
Thank you for your time. I truly appreciate your assistance. Steve from Tehachapi, Ca. NO it only means it was Made in Japan. I would think the Silver Streak was the top of the line unless the Viper replaced it that year. I would check Sparky’s DB site for more info on that year.
