Bicycle Warehouse New BMX Bike Buyers Guide
Congratulations on Your BMX Bike
Inspired by the motocross riding style and dirt jump tracks. From tricks and flips to cruising around town, these BMX bikes are all about action. Made with lightweight yet rugged frames, our collection of BMX bikes are ready to rip, be it the street, dirt, or the park.
Before you take off to the trails on your new mountain bike, you'll want to be sure it's set up properly and safe to ride. Follow our simple steps for mountain bike setup and you'll be rolling comfortably in no time.
If you purchased your bike from a Bicycle Warehouse store we've done most of the work for you already and you. If you purchased the bike online make sure to follow the manufacturer's assembly instructions per your owner’s manual.
Make sure to register your new bike with the manufacturer to ensure you receive any support should you need it down the road.

Make sure you have all the right tools to get the job done. Most of the adjustments can be done with a standard bike multi-tool however you’ll want a torque wrench to properly tighten components back up. This is especially true when working with carbon fiber components. Torque settings can be found stamped on the component, or in the manufacturer’s literature

How to Setup Your New BMX Bike
Adjusting the Saddle
To adjust the height of your saddle, you will need a way to hold the bike while you hop on to size up. A friend can help by facing you and straddling the front wheel while holding the handlebar. Alternatively, you can lean the bike against a solid surface.
Achieve a 25- to 30-degree bend in your knee. You can check this by putting the balls of your feet on the pedals and extending one leg to the bottom extreme of the pedal stroke.
How to Adjust
Use an Allen wrench, or a quick-release lever if that’s what is securing the seat post) to loosen the binder bolt and slide the seat post up or down accordingly. Pay attention to the “minimum insertion marking” etched into the seat post, as that is the lowest point at which the seat post can safely be ridden on. Once the saddle is at the correct height, retighten the binder bolt to the specified torque setting or re-tighten the quick-release lever.
Saddle Position
To verify your desired saddle position you will need a simple plumb bob, which is a string with a weight tied on the end. With your saddle at the proper height and one pedal in the 3 o’clock position, center the ball of your foot over the axle of that pedal.
Dangle the plumb bob off of the front of your knee so that the weight is hanging just above your foot. If the saddle is in an optimal position you can imagine a line running along the plumb bob’s string running right through the axle of the pedal. Have someone stand next to you to verify this makes it easier.
Saddle Angle
An ideal saddle angle is going to be level with the ground. A tilted saddle can cause hop and back pain, requiring you to waste energy adjusting your body while riding. A bubble level can be used to verify your bike is level.
How to Adjust
Loosen the Allen bolts securing the clamp that is attached to the saddle rails. Designs vary however they all function similarly. Slide the saddle forward or backward while rotating it into a level position.
With the saddle now level retighten the bolts and double-check your adjustments. When you’ve verified the height, angle, and level of the saddle is where you want it you can now retighten the saddle down back to torque specifications.
Adjusting the Brake Levers
Getting brake levers adjusted correctly helps with the ergonomics of your handlebars; improving your reaction time, bike handling, and eliminating fatigue.
Brake-Lever Angle
When the brake levers are at an optimal angle, your wrists will be straight. If your wrists have to rotate up to grab the brake lever it can cause you to lean too far forward while riding, reinforcing bad technique. If your wrists rotate down to grab the brake lever riders tend to drop their elbows sacrificing stability and control.
How to Adjust
Loosen the Allen bolt on the brake lever clamp and rotate until the levers are at a 45-degree angle. Retighten the bolt to the specified torque setting.
Brake Lever Position on the Handlebar
While riders often have their preference as to how many fingers they prefer on the brake lever and on the grip, most brakes are designed accommodate a two-finger grip, leaving two fingers and a thumb to hold onto the handlebar.
When setting up your lever position on the handlebar the goal is to have your middle finger nestled against the curved end of the brake lever.
How to adjust
Adjusting the lever position on the bar is simple. Loosen the Allen bolt on the brake lever clamp and slide the clamp inward or outward on the handlebar. Recheck the lever alignment and ensure it’s properly spaced and angled. Retighten the bolt to the specified torque setting.
How to Setup Your Tire Pressure
Tire pressure should be checked before every ride as many factors affect tire pressure, and tires lose pressure over time. Generally, it’s best to run your tire pressure as low as possible, while staying within the recommended PSI range stated on the sidewall of your tire. Running a lower PSI offers noticeable performance improvements including a softer, more forgiving ride and better traction. If you run the PSI too low you can risk pinch flats or burping the tire.
How to Adjust
The tools needed to inflate your tires include a pressure gauge and a pump. Many floor pumps feature a built-in pressure gauge for easy airing up. In addition, most modern pumps can fit both Presta and Schrader type air valves. A rough guideline for tire inflating is as follows, although as you get more experience most riders develop their own preferences on air pressure and PSI levels.
Follow the PSI range stamped on the sidewall of your tire. Adjust this accordingly in relation to the terrain you are riding on as well as rider & cargo weight.

Quick Tips
Brakes
Ride with confidence and never question your ability to stop. Keep your bike brakes well maintained with replacement pads, levers, rotors, calipers, and more. From disc to rim brakes ride faster knowing your brakes are ready to perform.

Cleaning Your Bike
Cleaning your bike is essential to keeping your bike running smoothly and performing at its highest. Proper bike cleaning should be a big part of your bicycle maintenance routine. Washing your bike regularly will ensure all your expensive bike parts have a long and happy life. Whether you ride a road bike or a mountain bike, taking the time to wash your bike (especially your drivetrain) is a necessity. For road bikes, we suggest degreasing and "re-greasing" your drivetrain every 100 miles. For mountain bikes, you should clean your bike after every muddy ride or every couple of weeks with regular use in dry climates.
