The 7 speeds relates to the number of crank rotations per rear wheel rotation - just like a car's gears. The more crank rotations (meaning pedal rotations) per rear wheel rotation, the easier it is to pedal. So, the highest ratio (or first gear) is for hills. Gears 5,6 or 7 would be for level ground and depend on how fast you want to go and how much wind there might be.
I discovered the absence of info also. I guess it's up to the rider to figue out via trial and error which gear to use. I found "1" to require too much peddling on level ground (similar to Overdrive in a car) and "7" is the toughest gear for climbing hills. But some hills are still too steep for me, so I push it up them.
The lower the number ( 1 )( 2 )( 3 )( 4 ) would be used for different grades ( ie: the steeper the grade the lower the number. Otherwise just use the ( 5 )( 6 )(7 ) numbers for flatter grade. I usually use the
( 5 )( 6 ) speed. ( 7 ) if you are really moving along and the grade is flat.
Thank you for your question. This is a common question when with bicycles with multiple gears. The most important thing here is that there is no such thing as the “right” gear. Choosing a gear depends on numerous factors. Really, gearing is personal preference, so you will probably ride in different gear than a fellow rider, even if you are going the same speed on the same road.
If you are approaching a steep hill climb, you want to shift down to an easier gear before you need to. The steeper the hill, the more gears you will want to shift down. Likewise, if you are going downhill, gradually shift up as you gain more speed. Another thing to keep in mind is starting and stopping. If you are riding in a big gear, you will want to shift down as you slow down and come to a stop. If you stop while you’re still in a big gear, it will be very hard to get started again. If you anticipate the stop and shift to a low gear before stopping, you will be able to start easily.
