When I started telling people I was going to open indoor cycling studio in downtown San Diego, lots of them said " Like Spinning?" I said, "Yeah, Kinda like Spinning, only better" For starters, "Spinning" is a registered trademark. Think of it like "Kleenex", or" Bandaid." Most people I know don't ask for a "facial tissue" or an "adhesive first aid bandage" But the fact is that those are registered trademarks, so someone who makes adhesive bandages or facial tissues cannot call them Kleenex or Bandaids.......no matter what the rest of us call them. So, I can't call my facility a " Spin" studio, or say that we do "Spinning" ...but that's fine by me. What we do is better. The Saris PT 300 power tap equipped bike is far superior to those "Spinner" bkes. And all of my instructorscoaches are real road riders, that help you get a workout that mimics real ride and gives you a great workout. If you want more info on spin, spinning, or spinner bikes, all ya have to do is do a google ( also a trademark!) search for those terms... and maybe Madd Dog Athletics....'cause that's who owns the trademarks.
