I have my old bmx bike from when I was a kid, I’m trying to do some research to find out the make and model. I got the bike second hand and it had been stripped and repainted, the serial number is on the bottom bracket. From what I can tell the paint was originally white, I got this bike in the early 90’s, so if I had to guess it would be from the 70’s or 80’s.

RD 04611

Any help would be appreciated, thank you.enter image description hereenter image description hereenter image description hereenter image description here

  • Unless you know the brand already, the serial number is no help at all. You might get some answers, if you post a couple of clear and well-lit photos of the bike - one from the right-hand side showing the whole thing, and a second showing a close up of some unique or distinctive part.

  • That bike wasn't stripped - the red paint is clearly still there. See if you can peel off the black, or possibly a gentle warming with a hot air gun might be enough to drop the top layer of paint. There may be info under the black paint. ALSO, the left-side chainstay has an interesting bracket, possibly to hold the reaction arm of a coaster brake or a gearbox. The web under the headtube looks quite distinctive. Rust on the BB says its a steel frame.

    I painted the bike black when I was a kid, it was pink when I was given the bike. The woman that gave me the bike told me her son had painted the bike multiple times.

Here is a 1986 Redline RL-20a with a frame that matches closely. Both the 1986 and 1987 (there are no RL-20a bikes in BMX Museum after 1987)

1986 Redline catalogue page 16-17 shows that the 20a frame is the one with the brake strap anchor.

It has the correct
- gusset
- off center bottom bracket down tube location
- brake strap anchor
- rear drop out shape, and general frame tube shapes.

Those handlebars did not come with that bike - no idea what they are.

  • I think you nailed it! The large oval bottom tube, and bracket. The brake strap anchor, everything is identical. Thank you so much for your research. The handle bars I found out last night are CW, they had to be swapped out by the previous owner. I also have a 84 redline 500a my son and I just finished rebuilding, now we can build this one knowing the correct parts to get. Thanks again!
