Depends on if it's twist shift or trigger shift. With twist shif, if you're pedalling just right, maybe 1/2 second to go from one end to the other. Trigger shift, maybe one second.
my merucry mystique dont shift gears fast
To properly shift gears on a bike, use the gear shifters to move the chain onto a different gear. Shift to a lower gear when going uphill or starting from a stop, and shift to a higher gear when going downhill or riding at a fast pace on flat ground. Make sure to pedal lightly while shifting to avoid damaging the gears.
Your 1994 Chevy pickup won't shift gears fast enough when the ac is on because their is a problem with it.
The best gears to use for mountain bikes are typically a wide range of gears to handle varying terrains, including steep climbs and fast descents. Look for a bike with multiple chainrings in the front and a wide-range cassette in the back for optimal performance on different types of trails.
it can probably go about 100 miles per hour and it depends about the gears how much gears it has
it depends on how on how fast you petal and how fit you are
Not particularly, 10 mph is below average sprinting speed. The record speed on a mountain bike is above 100mph.
If you pedal very fast then you may lose control
A mountain bike can typically reach speeds of 25-30 miles per hour on flat terrain, but can go faster downhill or with a strong rider.
A mountain bike typically goes around 10-20 miles per hour when ridden on rough terrain.
A mountain bike can reach speeds of up to 40-50 miles per hour when ridden downhill on a steep slope.
Too fast or slow of rpm for gear your trying to switch into A bad or going bad shift synchronizer
