For a while, 24 or 27 speed were considered the most accepted for mountain bikes, and this meant that three gears up front and 8 or 9 down at the back. Although, downhill mountain bikes have had just one gear up front and 8 or 9 at the rear, just to avoid the chain slap feared by riders, and also because they are designed majorly for going downhill.
The Enduro and Modern Trail bikes are moving to 11 or new in recent times, like in 2017, it moved up to 12 speed. That means a single gear up front and 11 or 12 at the rear. This solves the problem of chain slaps, when the chains make noise as they roll over each other, for most downhill sections, also avoiding the difficulties encountered by the front gear, difficulties such as chain coming off. The rider has a full range of gears that is required to go both uphill and downhill. And the new clutch technology for the rear derailleur has made this possible.
It is possible that while growing up, you rode a 26 inches wheel, although, in the last half decade or so, a few differences have featured on the market, like the 27.5 inches, also known as the 650B, and the 29 inches.
But why do people ride on bigger wheels?
This is because of two reasons:
And smaller wheels?
Bikes naturally come with flat pedals, but there are alternatives (a few of these). The standard bike pedals are flat, but most mountain bikes providers have other pedal types.
