This guide applies to any bicycle with a stem that has the option of replacing handlebars.
This includes most city bikes, touring bikes, tandems, road bikes and mountain bikes.
With some city bikes and transport bikes, the handlebars are part of the stem.
In this case, please consult the following link. (See Replacing the handlebar stem)
With older models, the handlebars can be mounted using a hex bolt.
With newer stem models and A-head handlebar cams, the handlebars are fastened with allen bolts.
The diameter of the middle section of the handlebars, where they are mounted on the stem, is usually 25.4mm.
Some mountain bikes and road bikes may have different diameters, like 31.8mm or 35mm.

Remove all individual handlebar parts, like the grips. (1)
A guide on how to replace the grips can be found through the following link. (See Replacing bicycle grips)
The brakes, shifters and bicycle bell can be loosened with an allen key and a screwdriver (2, 3), before being slid off of the handlebars.

Once everything has been removed, the handlebars can be loosened. (1)
Use the spanner or allen key to unscrew the bolts. (2)
Then remove the top cap from the stem. (3)
With older stem models, the handlebars may be held together with a clamp with one opening. If this is the case, the handlebars should be pushed through the stem.
Step 3 : Mounting the handlebars

Place the new handlebars in the stem and tighten the bolts enough that you can still adjust the handlebars. (1)
While the handlebars can of course be adjusted to your personal preference, the basic angle for city bike handlebars is 90°. For road bikes and mountain bikes, this angle may be slightly different.
When adjusting the handlebars, it’s important to ensure that the wrists are held at a natural angle on the handlebars, without putting too much stress on the bones, tendons and nerves.
Firmly tighten the bolts once the handlebars are adjusted properly.
Mount the handlebar parts - like the bell, the shifters and the grips. (2, 3)
On some stems, the tightening torque is indicated in Newton meters (Nm). Use a torque wrench to apply the right amount of force.
