Prep and Tools

The Almighty Unboxing

Make sure your bike is upright with the arrows printed on the box pointed upward.

Cut the binding straps to open the box and lift the bike out by the frame and rear wheel.


Place the bike flat on the ground with the attached front wheel facing upward.

Use scissors to cut the zip ties that secure the front wheel to the frame.

Remove the plastic protectors from the axle and set the wheel aside for the time being.

Next, remove the black protectors from the front and rear dropouts and any other packaging material. (Be careful to stay clear of those cables with your blade).

Leave the bike standing upright and you're ready to move on to the saddle and seatpost!

Seatpost and Saddle Install

Using your 5mm allen key, loosen the seat post collar.

Grease the inside of the seattube of the frame (not the seatpost, unless you want a mess on your hands).

Slide the seat post into the frame ensuring that the minimum insertion marker is below the collar and your saddle is aligned with the frame. (Fine tuning can be done later on).

Then, using your 5mm allen wrench tighten down the seatpost collar.

Handlebar Install

First, make sure your fork is pointed forwards and is aligned with the stem. Simply rotate the fork until it's facing the right way (brake on the front, axles pushed slightly forward of the headtube).

Now, to align the stem, use your 4mm allen wrench to loosen the two bolts securing the stem to the steerer tube.

Once loosened, twist the stem until it's aligned with the fork - then use your 4mm again to tighten the stem back to the steerer tube.


And now you're ready to add the handlebars! Using your 4mm allen wrench, unscrew the stem face plate from the stem (but keep it close by).

Center the handlebars in the stem in preparation for screwing the face plate back on there. Be sure to keep your brake and shifting cables out in front of the bars (you don't want them pinned behind the face plate or all wrapped up and tangled around the bars).

Then, replace the stem's face plate. 

Tighten each bolt a little bit at a time, alternating between opposite bolts so they all get tightened evenly. If you tighten each bolt all the way as opposed to a bit at a time, you can end up with misaligned bars or snapped bolts. Don't tighten them all the way yet either, just enough to get everything "almost snug" so we can adjust the bar angle next.

Now that your bars are held in place, we can tweak their alignment. Below: Incorrectly aligned handlebars.


Tilt your bars up or down until they're in a comfortable riding position for you. A good rule of thumb is to make the "flats" (top) of the bars and the base of the hoods parallel to the stem. Once you're happy, evenly tighten the face plate the rest of the way until you can no longer twist the bars out of position. (Make sure not to over tighten, you may damage your stem face plate).

And with the bars installed, you're ready to move onto the pedals!

Pedal Install

You'll want to unpack the pedals from the small included cardboard box. The pedals will be marked on their spindles with either an “R” or an “L”. This will indicate which side of bike the pedal will fit. “R” will be for your driveside and “L” will be the opposite. Pedals will often have "L" and "R" stickers too, but they can sometimes fall off in the shuffle, so just remember to check the spindles if you have any doubts.

Make sure that before you install your pedals you properly grease the pedal threads. This will ensure that you are able to remove your pedal down the line if you decide to upgrade.

Apply grease both to the threads on the pedal spindle and in the threads on the crank arm.

Now it's time to bust out that 15mm wrench We're going to start on the right-hand side of the bike (driveside). Take the pedal labeled “R” and carefully insert the pedal thread into the right crank arm and begin to turn to the right (clockwise). After the pedal is initially seated, take your 15mm wrench (clockwise still) and get that pedal tightened and secured. Make sure not to over tighten as this can cause stripping.

Now for the left pedal. Take the pedal labeled “L” and, again, begin by greasing the threads on the pedal and the crank arm.

Before we go any further it is vitally important to know that the left pedal is reverse threaded. This means that you're going to tighten the pedal by turning it to the left (counter-clockwise). “Lefty Tighty” might seem a little counterintuitive, but it is massively important to remember when installing your pedals.

Now, carefully insert the pedal thread into the left crank arm and begin to turn to the to the left (counter-clockwise). After the pedal is initially seated, take your 15mm wrench and get that pedal tightened and secured. Again, make sure to not over tighten as this can cause stripping.

After you've finished take a step back and marvel at your work. You're one step closer to having a built up bike! Let's pop that front wheel on there!

Front Wheel Install

Take your front wheel from earlier and grab the quick-release skewer from the small "parts" box where you found the pedals.

There will be small black lever on your brake caliper called the brake quick release, turn it upward to the open position (you should notice the brake pads spread wider when it's "open").

Now, remove the end cap and spring from one side of the QR skewer (the end cap just twists off, lefty-loosey).

Slide the uncapped end of the skewer through the wheel's hub, and replace the spring and end cap on the opposite side once it's through.

Don't tighten the end cap/skewer all the way, just give it a few twists so everything stays put on both sides.

Now align the front wheel and slide the tire between the brake pads, the axle into the fork.

Once your wheel is in place, tighten the quick release (hold the end cap and spin the qr lever clockwise). Then "close" the qr lever by pushing it up against the fork. You want it to be fairly hard to push closed, but no so hard that it's impossible. As a rule, it should be pretty tough to get it about 3/4 of the way closed, then it'll make the last quarter easily as it clamps "shut".


Making the lever follow the line of the fork is good practice because it makes it easy to "eyeball" that your lever is closed before you roll out and it'll keep it clear from snagging on anything on the road and popping open.

And now your wheel's on there, let's dial in the brakes!

Brake Adjustment

You'll make these adjustments to both the front and the rear brakes, so either work your way back and forth - or go all the way through on the front brake and then repeat the process for the rear.

With your 5mm allen wrench, loosen the bolt that holds your brake cable into the brake caliper. Your brake caliper will open completely, no worries that's a-ok!

Using one hand pinch the caliper until the pads are lightly touching the braking surface. With your other hand, pull the cable taut and tighten that 5mm bolt back up again. Once you let go you should only have a few millimeters of space between the brake pads and the rim on either side.

If you notice that one pad is much closer to the rim then the other, just push the calipers back to center. And, if you have a lot of excess brake cable hanging down, just give it a trim and re-clamp the end.

Now you'll want to align the pads to the rim. Loosen the 4mm bolt holding the pad into the caliper. Align the pad with the braking surface so that the top of the pad is close to the edge of the rim without contacting the tire (contact with the tire is BAD. It can strip important rubber form the sidewall and lead to a blowout).

Tighten down that bolt ensuring that the pad does not misalign.

Now, "close" the brake quick releases again and everything ought to be in place.

Give the wheels a spin to make sure that there's no contact between the tire/brakes/rim/wheel when the brake is not engaged, and you're all dialed in!

Safety Check

First, go over every bolt and make sure nothing is loose and we mean every bolt. Here is a list of bolts we have not gone over in assembly:

(1) Crank bolt - 8mm allen (if this loosened up in shipping your crank arm can fall off (bad).
(2) Chainring bolts - 5mm allen
(3) Water bottle holder bolts - 4mm allen

Final Adjustments 

We didn’t worry about getting that seat exactly where we wanted it when we greased and installed the seatpost. You can now loosen that seatpost clamp and center the saddle on the top tube of the bike and also adjust for height. Just remember not to raise your seatpost past that minimum insertion line.

Get your saddle level dialed in too, then hop on for a test spin. Just take it easy up and down the block, working your way through the gears and getting a feel for everything.

If you identify any unusual rubs, noises, etc... jump back into the relevant section and adjust accordingly. And that's it!

You're ready to roll! Congratulations!
