So, just what exactly do all the numbers found on a Chopper frame mean?
We’ve covered the frame numbers already, by now you should have located the frame number, on early bikes on the rear dropout, and on later bikes on the rear of the seat tube. If you are still in the dark about your Choppers frame number, click here.
The frames were also a registered design; basically they were copyrighted to prevent other manufacturers producing a frame of identical shape and proportions.

Des.No. sticker

The Mk 1 frames had a small sticker on the front of the seat tube, which had “Reg.d Design Nos 934256 934304” written on it, this sticker appeared in mid 1970 indicating that it took a while from submitting a design to actually being allocated a registered design number.
Why there were Design numbers I don’t know, but that first number is suspiciously close to the seat design number.
The Mk 2 bikes had a sticker that heralded not only its design number, but also its design shape… the Arrow Wedge.
Located on the right side thin top tube, in the area under the seat, the sticker originally said “ Arrow Wedge Design Applied For “ which ties in with our theory about the timescale involved in being issued a design number. Early Mk twos and Sprints had this sticker
An actual number didn’t appear until early 1974, when the sticker changed to read “Arrow Wedge Reg’d Des No 954915” Indicating a two year wait for the design number to be approved and issued.
Strangely enough, around 1977 the sticker changed number, and became “Arrow Wedge Reg’d Des No 954916” This was despite the frame design staying totally identical to the earlier bikes. If anyone knows the exact date or reason for this, please enlighten me!
The other design number found on the Chopper bike relates to the Seat design. The metal plate (where the reflector mounts) on the rear of the seat, has “Reg’d No 934257 Made in England” stamped into it. The same design number existed on the seat backplate throughout the production run of the Chopper, the same number being used on both Mk 1 and Mk 2 bikes, despite the discrepancy in length. This indicates that it was the overall design of the seat that was registered, and not exact dimensions.
The Mk 2 Chopper seat was used on the Raleigh Tomahawk Mk 1, and carried the same design details.
The seat used on the Raleigh Chopper Sprint and the Mk 1 Chipper, which was basically the Raleigh Fireball/Rodeo seat from a previous era, had no seat back plate, and no design numbers.
The Alloy base of the gear shifter mechanism merely had “Patent Applied For” written on it. This is something you would have expected to be patented, but for some reason it stayed “Applied For” for twelve years!
