How To Assemble A Bike Complete Guide 2022

If you’re looking to get around town on two wheels, you’ll need to know how to assemble a bike. This process is relatively simple and only requires a few tools. With a little bit of know-how, you’ll be riding your new bike in no time!

1. Unboxing

To open the box, hold the box upright and move your hand down the underside of its top flap.

To prevent any injury to your bike or yourself, you will need a large flat-head screwdriver.

For shipping, the handlebars and front wheel will need to be removed. Take the handlebars, front wheel, and bike out of the box and take away any protective packaging.

Unboxing the Bike

It would help if you kept the packaging in your possession. It will be helpful if you have to return the bike or need it to travel.

Make sure you check the box for any manuals or paperwork. Also, make sure to inspect any parts in a separate container. They will be needed later, so keep them safe.

2. Tools To Help You Do Your Job

Depending on how your bike needs to be assembled, you will need the following tools.

  • Allen (hex) keys
  • Optional: A small torque wrench (or torque key)
  • Bike grease
  • Carbon assembly paste (if you have carbon parts on your bike)
  • Pump

When tightening bolts, be sure to use a torque wrench, or key, if any of the bike’s components are made of carbon.

Carbon assembly paste is a paste that has a gritty texture to increase grip. It’s used wherever there is a carbon component. This is most commonly the seatpost.

You may be able to purchase the necessary tools from some retailers or bike manufacturers. We have included an essential torque wrench and a variety of bits to use it.

3. Place The Seatpost

Before inserting the seatpost, remove the saddle from the package. Later, we’ll adjust the saddle height.

Use a clean cloth to remove any excess paste.

Place The Seatpost

Note: The seatpost bolt for this bike is located at the rear end of the seat tube, in between the seat stays. Check the manual, clamp, or frame for the correct torque setting before tightening your seatpost clamp.

4. Attach The Handlebar

Now attach the handlebar.

Many newer bikes, especially mid-to-high-end road bikes, have integrated cockpits that combine the stem and handlebar. To ensure that the handlebar fits correctly, consult your manufacturer’s manual.

This bike has an integrated Canyon Aerocockpit. Slide the stem base onto the steerer tube and tighten the two stem bolts until they reach the required torque setting.

Attach the handlebar

Before nipping at the bolts, make sure the bars are straight.

If you don’t have one, you will need to replace your traditional two-piece stem/handlebar set.

  • The plate that holds the stem’s handlebar to its branch is located at the front.
  • Place the handlebar on the bolts and tighten them to the correct torque setting. Note: Make sure the bolts are tightened evenly. There should be an even distance between each bolt and faceplate. Some stems may differ. Double-check.
  • Next, loosen the bolt at the top of the stem by tightening the bolts at its base. Once you feel some resistance, The bolt at the top of a traditional stem fits directly into the star nut or bung in your fork’s steerer. This preloads your headset. This bolt has an Nm setting because each bike is different. Too loose, and the headset will move fore and aft; too tight, the headset bearings within the frame will be crushed. You should check for movement at the stem spacers and frame intersection.
  • Straighten the stem until it aligns with the front tire
  • Secure the stem bolts at the manufacturer’s torque setting by locking them together.

This assumes that the handlebar height does not need to be adjusted. We have a separate guide that explains how to change the height of the handlebars.

5. Place The Front Wheel

Place the front wheel in the fork.

There are generally two types of axles on a bike.

Thru-axle: The diameter and length of a thru-axle will vary depending on the bike. It bolts the wheel directly into the threads of the frame or fork.

Place The Front Wheel

Quick-release Skewer: A thin skewer that passes through the wheel. The bottom of the fork and rear frames have dropouts (open slots) to pass over the hub’s axle. The threaded end of the skewer holds it in place with a nut.

After the skewer has been threaded into a nut, the lever will be used to adjust the tension and clamp the frame onto the hub’s axle. The lever should be closed with enough force to make a mark in your palm. Because brakes can rub if the dropouts are misaligned, make sure you have the wheel straight.

Notice: Rim brakes are required to ensure that the front wheel is in the correct orientation. Locate the direction arrow/rotation arrow on the sidewall. Lightly grease the thread of the thru-axle if the bike has disc brakes before inserting it through your fork and wheel.

6. Inflate The Tires

Check the pressure on your tires by inflating them.

7. Install Pedals

Although your bike may come with inexpensive pedals, most riders will opt to own it.

Grease the threads of your pedals, and then install them with a pedal spanner (or Allen key, depending on the pedal).

Notice: The pedal threads are side-specific. Both pedals go in the forward direction. You should mark the pedals with L and R if you are unsure which side they go.

8. Adjust The Saddle Height

Make sure the bolts on the saddle rail are tight. Also, make sure the saddle is straight and level.

Next, tighten the seatpost clamp to the recommended value.

9. Final Checks

Manufacturers and retailers should have installed the brakes, gears and cables before despatch. However, the bike should be inspected for safety, and the gears indexed correctly.

It is an excellent opportunity to take a picture or note of your bike’s serial number in case you need it.

10. Go ride!

Take a spin, feel the brakes, and check for any niggles.



So there you have it, the basic steps to assembling a bike. If you follow the instructions and check for errors along the way, the assembly shouldn’t be too complex.

Even if you’re a little nervous, putting together a bike is a great way to get familiar with bike assembly and maintenance. You can’t go wrong with building a bike in your garage or taking on a challenge from your local bike shop crowd. BSXInsight hopes this tutorial is helpful!
