I think a company called Cool Gear (The Jacobs Corporation? based in Colorado?) was responsible for "The Seat." They didn't seem to realize that cyclists often lift up the bike by the saddle. I think their saddles kind of snapped in to the rails? Then when the leather saddle pops off, you've got these upward-pointing rails (reminiscent of insidious torture devices) underneath your butt! Not very safe or comfortable at all...

I used to use Avocet computers. They came in different colors. The magnet was a round thing that clipped to the side of the hub. It was fine until you used some sort of non-standard aero wheel or hub that would not accept the ring. I stopped using them when they kept resetting by themselves, or failing when they got wet (screen would just go completely blank). Switched to Sigma and have been mostly happy ever since. They also had a more expensive version that included an altimeter. Greg Lemond pushed them for a couple of years, then when the sponsorship expired, he sued the company because they kept using his picture in their ads...

I think the big problem with Teledyne Titans was that they were made of pure titanium, rather than the refined 6Al2V Ti alloy. As a result, they (like the previous Speedwell Ti frames) handled like limp noodles. They also broke apart pretty easily.

Funny bikes disappeared when the UCI mandated same wheel size, front & rear. But you still see small front wheels (24") used on stayers' bikes, used for motorpaced races in the pro 6-days. But these have the fork reversed so the rider can get closer to the roller, and to make the bike handleable at 80+ kmh behind the motor!
