The older I get, the faster I used to be ...
In such a case I imagine the buyer would have nothing to compare the purchased bike with and would be accepting of the bike and it's equipment. The pedals are invariably basic flat double sided, so no SPD issues The saddle may or may not be comfortable. They may well decide to change such equipment after riding the bike for a period and as their experience grows.Not meaning to be picky or argumentative but I'd imagine a lot of people who buy a bike for the first time wouldn't think of such things.
Lots of people buy bikes and ride them without ever joining a forum like this.
Many do so online without the sales pitch to upgrade pedals etc. or buy in mass market superstores where there is little service. They want a bike. They buy a bike. They ride it.
I've never bought a new bike but something would strike me as odd if the salesperson effectively said that the pedals, saddle, wheels and tyres weren't fit for purpose.
I'm all for trying something out and finding out for myself what I'd like to change but not from the very start. If I'm a complete beginner is a lighter tyre such an advantage?
