I have measured the width of the rear swinging arm and it appears to be the same as for my 61 road cub 160mm inside, 175mm outside diameter so at least for now I can fit a standard cub wheel to it. I have seen while looking for a replacement wheel that there are "trials" axles, can someone tell me what the differences are?

 

 

BSA C15 frame with a tiger cub back end and a tigress engine, good fun.

Very interesting project .. im dreaming further i will love to hear its engine sound if someone can post a video . Tigress never thought she will be climbling hills and having muddy facial

hi, have read this thread a number of times, now in the new year am gonna build a twin 250 from a Sunbeam engine i have and a Cub/Bantam frame,

is there anybody out there that can help me with the final gearing, (i like my bikes geared on the low side)

thanking you,

We are still looking for the  bike. I have drawn a blank so far. The only thing I have been told is it may have gone abroad  after the plate  was removed and sold to mr porche  owner. I am intrigued to know if this bike had a frame number from bsa being a experimental bike
