Over the last couple of years, there has been a surge in the demand for bikes, people have been either getting a bike furiously or trying to get one. The pandemic paved the way for this ridiculously large demand, it was almost unreal. People started ditching their cars and public transport to save costs and the risk of having contact with someone else and started using bikes.

You might have seen people buying bikes yourself, and even you might be one of them. People have been getting bikes from either their local bike shop or online. If we compare these two options then getting a bike from an online store is always better, that is how you have more choice and there is also the option to “Build Your Own Bike”.

Buying Online vs From A Local Bike Shop

There is this eternal debate over the topic if one should purchase bikes from an online store or a local bike shop. Should you ever purchase a bike from a local bike shop?

Paying a visit to a bike shop is a very good idea, especially if it is your first time buying a bike. Since you don’t know about the components and everything, there will be skilled help in the store to help you with the best products according to your budget range. 

Apart from this, you would also be able to try out the bikes before buying them. A great fit is necessary if you want to ride your bike perfectly, you don’t want to have a bike that is either too big or small for you. Brands in the store would be eager to give you a discount or deals as compared to buying from an online store. Plus, if you are a beginner, then one of the skilled bike mechanics from the shop would be more than happy to assemble your bike when it reaches your home.

If you opt for an online store, then there are still great benefits that you will be able to enjoy. After all, it is all about the benefits and the comfort that most cyclists are after. In online stores, there is a wide variety of bikes to choose from, plus there are also amazing discounts that you can enjoy. The only downside to all of this is, that you will have to assemble the bike yourself. That is what the goal of our guide is, to show you in easy steps how to assemble your bike.

Let’s start with our guide, this will cover all of your questions about assembling a bike.

Tools Needed To Assemble Bike

Without the right tools, you will be stopped dead in your tracks when assembling a bike. Here are the tools that are necessary for assembling.

  • Hex Allen Keys
  • Bike Pump
  • Grease
  • Torque Key
  • Torque Wrench 
  • Carbon Assembly Paste (In The Case Of Carbon Parts In Bike)

Unboxing The Bike Box First

For the first part, you won’t need a bike mechanic at all. In this step, you need to pull the bike out of the box. Use a screwdriver or other tool to remove all the staples that are on the box lid, this will make sure that there are no damages to the bike and you are also protected from injuries.

The bike will not be whole when you will be removing it from the box. The front wheel of the bike and handlebars will have been removed because of shipping. Pull out the bike, the wheels, and handlebars from the box carefully. Make sure that you also remove the protective packaging with care, you will be needing it in the future.

Note: Most of the time there will be a manual or some important paperwork in the box. Tools and small parts will also be included in the box, take them out and store them somewhere safe separately.

Inserting The Seatpost With Care

In the next part, we will be inserting the seat post on the bike. Unpack the seat post first, you will notice that the saddle is still attached to it, and in the majority of the bikes, it is. The seat post would either be carbon or metal. If the seat post is carbon, put a little bit of carbon assembly paste and if it is metal, then apply grease. Both of these pastes will be applied inside the seat tube. Make sure that there is no extra paste on the parts, if so then just wipe it away with a clean rag.

Sometimes the Seatpost clamp bolt will be at the rear of the seat tube. Prior to tightening the clamp post, check the manual for the correct torque setting.

Attaching The Handlebars 

Attaching the handlebars comes next and that is why you have to proceed with caution. Chances are, that you would be getting one of the latest bikes, seemingly mid-tier to high-tier if you have planned on purchasing it online. These bikes come with integrated cockpits, which means that the handlebar and stem are one. You will need the manual in order to see how to fit the handlebar properly.

If you have a bike with a traditional two-piece stem then you will have to do things differently. First, you would have to remove the front plate of the stem, this is what holds the handlebar to the stem.-

Check the torque setting next and insert the handlebar, tighten the face plate bolts according to the torque setting mentioned in the manual. The next part might be a bit tricky so be careful and attentive.

The bolts at the top of the stem need to be tightened so that there is resistance, this needs to happen when the bolts at the base of the stem are also slackened so that there is a balance. Since we are dealing with a traditional stem, the bolt on the top of the stem will be screwed directly into a star nut, which will go within the fork steerer, this will result in the headset being preloaded.

The Nm setting for this bolt is always balanced, it cannot be too loose or too tight. Now, you need to straighten the stem so that it is on par with the front tire, they need to be in exactly the same line. In the end, just clamp the two stem bolts in accordance with the torque setting provided by the manufacturer.

Front Wheel Installation 

It is time to insert the front wheel into the fork now, since there are two types of axles in a bike, things will be done differently for each type.

  • Thru-Axle 
  • Quick-Release Skewer

Thru Axle 

The Thru Axles are going to vary from bike to bike, as their diameter and length will be different. With Thru Axles, things are also very easy as they bolt the wheels straight into the frame of the bike without any kind of complications.

Quick-Release Skewer 

This is where things get difficult as they are nothing like a Thru Axle. This is a narrow type of skewer that passes through the wheel and that is where the differences start. At the fork and rear of the bike frame, there are open slots that are located over the hub axle. This quick-release skewer is fixed properly with the help of a nut, this skewer is attached to the threaded end of the frame.

Now that the skewer is threaded into the nut carefully, we will be using a lever to push for the tension so that it doesn’t budge. This is how the frame is clamped on the hub’s axle. All you have to do now is close the lever. The front wheel needs to be in the perfect position as misalignment can result in the brakes being rubbed against each other or much worse. Be sure to pay extra attention to the brake pads and brake levers, they could be damaged along the way.

What To Do When There Are Different Brake Types?

Your bike could have two different types of brakes, and that is why you would have to do things differently.

  • Rim Brakes
  • Disc Brakes

Rim Brakes

The first possibility is that you could have rim brakes, in this case, it is advised to check what kind of orientation the front bike has. This can be done by checking the direction arrow located on the sidewall.

Disc Brakes

In the case of rim brakes, all you have to do is apply some grease on the thru-axle prior to inserting it through the wheel. Do this perfectly and there will be nothing to worry about.

Inflate The Tires Properly 

In the next step, we will be inflating tires and you need to do that in accordance with the manufacturer’s guidelines. 

Best Tire Pressure Levels For Different Bikes

Different bike types have different recommended levels of PSI. Make sure that you follow them when using the bike pump:

Double-check the tire pressure levels before you head out as even the smallest mistake could result in huge problems.

Pedals Installation

There could be two outcomes here, if your bike comes with good pedals then you install them. In the other case, your bike could come with below-average pedals and you would want to remove them and swap them for something better. 

The first thing that we need to do here is grease the pedal threads and then install them. We will be using the Hex Allen keys for that. If you get confused about the left pedal or the right pedal, then they come marked with an L or R.

Setting Up The Saddle Height 

You need to set up your saddle height according to your comfort levels. Although before we start doing that, the saddle rail bolts need to be tight enough. The Seatpost clamp also needs to be tightened, after this set the best height for yourself.

Make The Final Inspections 

Now that everything is done, it is time to make the final inspections of your bike. These preparations will differ when dealing with kids bikes as they are smaller and require less effort. A Mountain Bike or a Road Bike will have the same proceedings though.

Do something fun here for a change, check the brake disc and the quick release mechanism, and then proceed to take pictures of your bike. You did good, be proud of yourself and celebrate!

Time To Ride!

Now that all the inspections are done, it is time to go for a ride and test drive your bike. Even if it feels clanky at first, things will fall into place with time. You can get your bike checked through a professional bike mechanic when you are done. This is it, you have finally assembled a bike successfully!
