ferretfixer Posted October 24, 2022 Share Posted October 24, 2022 Hi Folks! Not sure if this is the correct section to post this. But if not, admin please move to where it should be! 😉 I have just acquired a BSA folding Paratroopers folding bicycle. & There are, as is usually encountered on some of these. Some 'Standard' Bike pedals fitted. which is obviously not as they originally left the factory! Could anyone assist Me please? With some close-up photos, of the sliding spindle pedals shafts. & Supply dimensions of length, end to end. & The diameter of the Washer that is rivetted on each end. I will have to make them, unless anyone has one or a Pair, that they would be willing to part with? Thank you in advance for any Help / Assistance proffered! 👍 Regards to all Fellow Members on here! Mike. Quote Link to comment Share on other sites More sharing options...

I need a pair myself as the grips fitted,are period rubber ones. But not BSA Marked. I do believe there are repro's available? Mike Quote Link to comment Share on other sites More sharing options...
Enigma Posted November 18, 2022 Share Posted November 18, 2022 Glad to be able to help mate. The grip that broke on mine is I think a repro. Its quit a thick bakelite while originally there was one complete and part of the original ones on it. Repro's are thicker and noticibly heavier. Also the repro's are closed one 1 end. Because the original ones are way thinner there is parer between the handlebar and grip itself. See pic. BEWARE when attaching repro's; don't whack them on! Big risk to break them. Carefully slide them on to find out if they fit loosely or bind up immediately. I ended up after another breakage to sand it on the inside to reduce its internal diameter and used painters tape on the handlebars before sliding the repro's on. After my repair yesterday I'll sand some more to get a better fit. In the photo's the 2 original ones on the left, repro on the right 1 Quote Link to comment Share on other sites More sharing options...

Le Prof Posted November 19, 2022 Share Posted November 19, 2022 (edited) Hi Chris @sirhc Thanks for sharing your number, I appreciate it. I make that R21005. Here's a screen shot to give you an idea of what I'm doing: The points recorded above are the serial number, the frame tpe (early twin tube, or later single tube), the original colour, (brown or green), the colour of the undercoat (almost always black, one red example)), the frame hingre (most are cast metal, the very earliest are angle iron), the wingnut (most are smooth, a small number BSA marked), the tommy bar on the handlebar nut. Early ones are welded onto the nut, later, most common 'standard' go through the nut. And finally, the pedal arm reinforcement. Erly ones are just straight (No), later ones have a boss on the arm end to help support the pedal peg. If you can supply any of these details it will be further help, thanks. Your bike is a quite early single seat tube (so called second pattern) version. The early ones were painted brown, and yours is bracketed by original brown ones, but is within 100 frames of a known original green, so it could have been brown originally, or one of the first green ones of the second pattern. The serial number has the characteristic oversize 2 used at this point. It would have the early pedal arms with no boss. It also occurs just before a very small number that were fitted with BSA marked wingnuts on the frame BSA marked wingnut, cast hinge. Photo Credit, Enigma. Later pedal arm with boss to support pedal peg. If I can help further, please let me know.

sirhc Posted November 19, 2022 Share Posted November 19, 2022 Thanks Adrian, I will get some photos for you later in the week. The bike is now green but it’s likely it’s been repainted at least once. 1 Quote Link to comment Share on other sites More sharing options...
Enigma Posted November 19, 2022 Share Posted November 19, 2022 My must be a very late one. Its in the R48*** range, has a smooth wingnut (no logo), black undercoat, painted green and has all the original decals. What does quill type and pedal boos mean? (I'm Dutch.) Still have the original outer tyres (removed from bike) and I think I use a original inner tube. BTW, I have seen 1 folding bike with BSA on its individual chain parts.

Le Prof Posted November 20, 2022 Share Posted November 20, 2022 Hi @Enigma Thank you for your reply. R48XXX would be a 1943, and slightly over mid production. The latest S/N known so far is R77527. Numbers I have listed close to yours are: Quill is the correct technical term for the bracket that attaches the handle bars to the steer tube (A ). Really, I'm interested in the bolt that the tommy bar on the handlebar is attached to (C). I think I will change this heading to Tommy Bar, thanks. Diagram: Park Tools. Here is an early Tommy Bar, there is some variation in welding, and only the first 4 or 5000 bikes have this style. Photos: John Neuenburg Standard type: The 'Angle Iron brackets look like this, again, an early feature, and seen on the first 2 to 2500 bikes. Cast type look like this: Thanks, Best Regards, Adrian Quote Link to comment Share on other sites More sharing options...
Le Prof Posted November 20, 2022 Share Posted November 20, 2022 (edited) Hi Mike @ferretfixer Thank you for your reply. R54799 has now been included. (-: Below are some other known survivors in the same s/n area. There's not much variation, since this is really the final and standard pattern ofthis bike. Original markings are a rarity, and several of the ones close to yours don't have them any more. This is R57543, which clearly has the white Patent N°. But has had the piled rifles erased Full details here: https://thecabe.com/forum/threads/ww2-bsa-paratrooper-bike.167290/ You seem to have a choice on the piled rifles. R53105 is slightly before yous, and in near NOS. https://www.worthpoint.com/worthopedia/bsa-paratroopers-paratrooper-british-440653139 Slightly later is R57773, which claims to be (and looks) NOS. https://www.worthpoint.com/worthopedia/bsa-paratroopers-paratrooper-british-454042430 If I come across any Grip suppliers, I'll let you know.

One type and the most common is the cast type, the other is the down tube welded directly to the bottom bracket. You can see the difference in the pictures below, Regards Gary 1 Quote Link to comment Share on other sites More sharing options...
Le Prof Posted November 22, 2022 Share Posted November 22, 2022 (edited) Hi Gary @garys39 Thanks (I think....!) (-: I didn't know about that, it's an interesting observation. It looks like I'll be having to go back through the listings again. It's strange how, other than the twin and single saddle stem types, you tend to assume they are all the same, but the are several variations out there. This may be an early/late thing. T13439 early single tube production (my photo), tube welded on to the bottom bracket. R47383, mid production (Photo, Wing your Heel) Socket for tube on bottom bracket. R61090, late production (Photo, Wing your Heel) The early Twin Tube version has them welded direct to the bottom bracket, so perhaps this was continued onto the single tube version whilst they used up the bottom brackets on hand, or they found there were still problems with strength in this area, and reinfirced it with the socket? We'll see. R2485, Twin Tube (Photo, Wing your Heel). Note broken frame welds too. Thanks for your help. You wouldn't happen to have the serial numbers of those two frames, please?

ferretfixer Posted November 22, 2022 Author Share Posted November 22, 2022 Adrian, Note also. The Frame cross tube Reinforcement, ONE has a hole. One does not. Not sure if this is an Air hole used when welding originally to allow air pressure to escape? Or its purpose was for a Mudguard? Perhaps taken from other bicycle parts during construction? 1 Quote Link to comment Share on other sites More sharing options...
Le Prof Posted November 22, 2022 Share Posted November 22, 2022 Hi Mike @ferretfixer It's an interesting point, but I can't get enough pictures of that area to know if it's a real feature, or drilled to fit a mudguard. I suspect the latter. At the beginning, I noted when the rear drop out lugs had been drilled for mudguards, but I've seen enough now to say the pattern is random, and some of the holes are really badly drilled. So, I'm pretty convinced they had undrilled lugs from the start. Gary, @garys39 I've done a first run through looking at the welded versus lugged saddle stems. Roughly, R? to R10000 aren't included because they are twin tube saddle stems. R10000 to R30000 the stems are welded direct to the bottom bracket. R30000 to R78000 have a lug on the bottom bracket for the stem. Best Regards, Adrian 1 Quote Link to comment Share on other sites More sharing options...
ferretfixer Posted November 23, 2022 Author Share Posted November 23, 2022 (edited) Just ordered the piled arms & patent number decals in white from Ebay. Still looking for the Black Arrow ( Pheon ) Decal now! 👍 Edited November 23, 2022 by ferretfixer 1 Quote Link to comment Share on other sites More sharing options...
Le Prof Posted November 23, 2022 Share Posted November 23, 2022 Hi Mike, @ferretfixer I think white is the best choice. I'm halfway through reviewing the bikes on my list, and it's surprising how few have the original markings. Also, almost all of the piled rifles are white. All of the patent markings are white, and the pheons black so far. There's someone selling what appear to be sticker versions here, if nothing else turns up: https://www.ebay.co.uk/itm/261261651518 Best Regards, Adrian 1 Quote Link to comment Share on other sites More sharing options...
ferretfixer Posted November 25, 2022 Author Share Posted November 25, 2022 Adrian, Yes I need an Arrow ( Pheon ) but I'm not paying that Price! 🙄 Just a yank trying his luck! As you know, they should be transfers. Not sticky plastic badges! Regards: Mike 👍 1 Quote Link to comment Share on other sites More sharing options...
