Wicked, only just seen this thread. An old Activator from upstairs was my first "pay cheque" from work experience at McMahon's (Shrewsbury Cycles). I knew it was a steamer, but it had rapidfires and some other bits I wanted so a deal was made. I actually kept the rest of the bike, painted the frame WD-40 esque yellow/blue (Hammerite of course) & made it into a fixie tow-path troll, agree it was a hunk of pig iron better suited to anchoring the boats than riding alongside but I actually believe it made a better cyclist of me, with it's undamped pogo-fork twitchy front end & high weight plus terrible brakes (steel rims, yummy). I even rode it clipped in & one-legged one time after the NDS crank inevitably worked loose, got some looks!
I must have always been a little perverse, because I actually enjoyed riding the thing & I'd own another one for nostalgia sakes too (still wouldn't hand over cash money for one though!)
