Our bikes arrive to you about 85% built. Generally, that means you'll need to attach the front wheel, pedals, handlebars, saddle, and any accessories. (This will be the case with every bike you purchase online.) All of the tools you need to assemble your fixed-gear and city bikes come in the box. You'll need to grab a few tools before you can start building your cruiser and coaster, though.

We highly recommend taking your bike to a qualified bike mechanic to make sure your bike is safe before riding. He or she will need to set up the derailleurs and brakes and true the wheels.

Please keep in mind our bikes travel quite a bit to get from our warehouse to you and sometimes they can get hurt during transit, despite our best packaging efforts to keep them safe. Inspect your bike as soon as you receive it and contact us at team@criticalcycles.com if you have any issues.

You'll find links to our assembly pages below. On each page, you'll find links to PDF instructions, text instructions, and still images. You'll find the images at the bottom of the page. Scroll down to find your bike!
