Bike Assembly Tools: How to Assemble a New Bicycle

Once you get a great deal on a new bike by ordering online, easy task for just about anyone with assembling your bike which the bikes ship partially-assembled in boxes. Since there are so many different types of bikes and components available, I’ll give a brief overview of the assembly.

Bike Assembly Tools


With a few tools and some elbow grease, you’ll be off and riding in no time. The necessary tools include wire cutters, a set of metric allen keys, a set of metric open-end wrenches, flathead (-) and phillips (+) screwdrivers, cone wrenches, a pedal wrench and an air pump.

Open the top flap and carefully pull everything out of the box. Apply some grease to the inside of the seat tube, slide the seatpost in to the minimum insertion mark, grease the threads of the seatpost bolt and tighten it just enough so it will hold the weight of the bike.

Remove the front wheel by using wire cutters to carefully snip the zip ties. To save these for future use, cut them just before the head and then pull out and recycle the remaining piece of zip-tie. This leaves you with a short piece of zip-tie that can be used again for odd jobs. Remove the rest of the packaging and either recycle it, or save it so you can box your bike up in the future.

If your headset and bottom bracket have loose ball bearings, open them up and check for grease and adjust as needed. If you have sealed cartridge bearings in these places you can skip this step.

  1. Now we’re ready to install the handlebar. Grease all of the stem bolt threads and shaft if you’re installing an older quill-style stem. Then center the handlebar and tighten the stem bolts evenly so the gap is equal on both sides. Tighten the top cap just enough to hold it in place.
  2. Remove the rear wheel and cassette or freewheel , and open the hubs on both wheels to check for grease. Add more grease as needed and then adjust the hub cones so they spin freely with very little play.
  3. It’s a good idea to grease the threads of the crank bolts, chainring bolts, and other bolts that hold accessories like water bottle cages. This will help them repel water and dirt and stop them from seizing up. Grease the pedal threads and install them. Remember that the left pedal always has a reverse thread, so you have to tighten it by turning counter-clockwise.
  4. Set up and adjust your brakes. Then lube the chain and adjust the derailleurs. Then inflate the tires to the recommended pressure and install both wheels on the bike. Adjust your seat height and angle, align your handlebars and adjust your headset.

For multi-speed bicycle, the problem with assembling your bike is that everything is cable activated. Outside of the cables, the bike should be fairly intuitive to put together. And these cables need to be tightened and loosened in order for the bike to shift and brake properly.

If you do everything but the brakes and shift cables, your shop should be able to do those for about $40. However, the shift cables do stretch a decent amount over their first 100 miles of riding, or so. You may find that they need even more tweaking after you’ve ridden it awhile. And that can be another $20-$40 to get those adjusted again.
