GMC Denali Road Bike – Review, Tips & Guide

Looking for a bike that can go the entire length of your journey with you?

It can be hard to find a great entry level bike that won’t break the bank. But it’s not impossible.

When it comes to finding a mountain bike that’s easy to use but still gets the job done, the GMC Denali Road Bike is the best option on the market right now.

I’ve owned the GMC Denali Road Bike for a few months, and it just keeps getting better and better. I can use it to bike to work on nice mornings during the week, and then take it with me a few towns over to hit the trails that go through some of the smaller local mountains.

I have yet to meet a terrain or situation that the GMC Denali can’t handle.

Quick Comparison 

1. GMC Denali Road Bike



If you’re looking for a bike that’s going to last, even if you ride it every day, the GMC Denali bike is the only bike you should consider.

This bike is great for beginners, but it’s also a superior option for more seasoned cyclists. Its claim to fame is its reliability. You don’t have to worry about finding yourself stranded if you’re riding the GMC Denali.

The bike has 21 speeds and an aluminum frame that makes it easy to carry when you either can’t or don’t want to pedal. The brakes give you excellent control, even in wet weather, and the Shimano Revo shifters make switching gears incredibly easy.

Even if you’re a novice, you’ll feel confident and safe while riding the Denali.

You can use this bike for just about anything! Whether you need it to get to work, to exercise some of that weight off,, for training or racing, or just for the pleasure of riding a bike through beautiful scenery, you can count on the GMC Denali.

2. GMC Denali Women's Road Bike



My wife noticed how much I was enjoying my new bike and what a positive effect it was having on my health. 

I would spend a few hours every weekend exploring the neighborhood or local parks.

I could tell she was getting a bit jealous, so I got her her own GMC Denali women’s road bike last month for her birthday. She fell in love with it right away.

The frame is made from aluminum so it’s light enough to carry or push if needed, but don’t let that fool you. It’s still a very durable bike. The brakes help her stop on a dime, no matter what the weather may be.

She also finds that the Shimano Revo shifters found on this bike make it easier to shift than any other bike she's ever used. And she loves the pink touches throughout!

Some companies make plenty of bikes for men but only one or two for women. And many times, those models aren’t even close in quality when compared to the men’s bikes.

GMC does it right. They offer a variety of bikes for both men and women, each with a long list of options and specs.

Whether you’re male or female, tall or short, experienced or inexperienced, you’re sure to find a GMC bike that’s perfect for you.

Size, Weight and Dimension Options

There’s no one-size-fits-all model when it comes to the Denali.

They offer plenty of sizes so that you can find the one that works best for you. The GMC Denali Road Bike comes in a total of four sizes, with the dimensions as follows:

  • X-Small/41cm
  • Small/48cm
  • Medium/57cm
  • Large/63.5cm

When choosing a size, you’ll want to make sure that you can reach the handlebars without having to reach too far. You’ll also want your feet to comfortably touch the ground. If they don’t, you’ll have trouble stopping and going.

Just like clothing, sizes can vary. If you’ve purchased a small bike before, don’t assume that you’ll need the same size with a Denali. I usually ride a large bike but found myself more comfortable with the medium.

On average, the GMC Denali bike weighs about 29 pounds. This is a bit heavier than most bikes, but you’ll still be able to move your bike easily up stairs or over big bumps.

Superior Design

GMC bikes are designed with all types of users in mind. There are plenty of color options, so you’re sure to love the look of your bike. If you’ve read a GMC Denali Road Bike review, you know that their design is one of the top-rated features.

Size Options

No matter your height or weight, there’s a Denali bike that will fit your needs. Because there are so many size options, there’s one that seems like it was made just for you. This makes it easy to suggest the Denali to others, because there’s sure to be a size that’s perfect for them as well.


This is my favorite pro of the Denali bike. The price is unbelievable. For such a high-quality bike, the price is more than fair. Even if something happens to your bike and you need to purchase some GMC Denali road bike parts, you’ll be pleasantly surprised with how affordable it is to fix your bike. For only a couple hundred dollars, you can be on the road in a flash without breaking the bank.


Difficult to Put Together

The Denli doesn’t come assembled, which means that you’ll be responsible for assembling your bike. If you’ve assembled a bike before, like the Vilano Shadow, this shouldn’t be too big an issue, but if it’s your first bike, definitely take a look at my detailed assembly instructions. Once you get going and make some progress, the bike should come together fairly quickly.

Brake Problems

Some users have reported issues with the brakes on GMC bikes. I haven’t had any issues with my bike, but if you do find that your bike is slow to stop, a quick adjustment is usually all that’s needed to have you functioning at full capacity.

Flat Tires

I did experience a flat tire pretty quickly after riding my Denali for the first time. I don’t know if there was a problem with the tire or if it was my fault. If this does happen to you, it’s pretty simple to replace road bike tyres. Simply remove the wheel from the bike and deflate the tire completely. You should then press one side of the tire bead over the edge of the tire rim. Find the leak or leaks, and patch with a tube repair kit. You can also replace the tube for better peace of mind. Once the leak has been taken care of, you can remount the tire onto the rim.

GMC Denali Road Bike Assembly

Even if you’ve never assembled a bike before, you should be able to handle assembling your new Denali bike. Before beginning, gather the following tools and equipment:

  • 5/6mm hex wrench
  • Torque wrench
  • Air pump and tire gauge
  • Bicycle lubricant
  • 6” adjustable wrench
  • Phillips and standard screwdrivers
  • Pair of pliers that can cut cable

Now that you have your items, unpack the bike. You should find the frame, 700c tires, manual, pedals, water bottle holder, lights, and other pieces.

Make sure that the frame size is correct. If you’re not using the right frame for your height, you can easily injure yourself.

Ready to assemble your bike? Let’s start!

1. Free all bike pieces from protective coverings.

2. Take the white light and loosen the top screw so that you can move the light. Position it in an “L” shape. Loosen the bottom screw so that you can slide it onto the handlebars. Position it as desired and tighten with a screwdriver.

3. Position the handlebars on top of the frame and snap them into place. Make sure that the handlebar stem has been pushed far enough into the tube. There is a minimum insertion line that should be completely covered when done correctly.

4. Remove the plug from the top of the handlebars and use an allen key to tighten the handlebars, adjusting as needed so that the handlebars turn as needed. Make sure you check the steering by straddling the front wheel and turning the handlebar. The stem is too loose if you can turn the handlebar without the front wheel moving.

5. Flip the bike over and loosen the bolts on the front tire.Remove nuts, washers and wheel retainers from the axle, if necessary. Depending on the packaging, they might be present or packaged separately. Slide the wheel onto the open ends of the fork. Hook the retainers into the holes in the fork. Add the washers to each end of the axle and then add the hex nut on each side. Make sure that the wheel is centered, and then tighten the nuts to secure. To make sure that the wheel is centered, spin it quickly. It shouldn’t wobble. If there appears to be an issue with the wheel, loosen the nuts and try to center it again.

6. Next, take the pedals and place them in the proper slots. Tighten the base of the pedal until it no longer moves. The pedal itself should still turn, but it should be tightly secured to the bike. Make sure that you’re putting the left pedal on the left side and the right pedal on the right side.

7. At this point, the handlebars should be secure, along with the front tire and both pedals.

8. Grab the saddle and the red back light.

9. Loosen the red light similar to the first light. Loosen the top screw so that you can bend the light into an “L” shape and then loosen the bottom screw so that you can slide it onto the saddle bar and tighten it again.

10. Use an allen key to loosen the tube that the saddle slides into. If you don’t loosen it, the saddle will not be able to slide properly. Slide in the saddle and then tighten it to secure once you have the seat at your desired height. This might take an adjustment or two.

11. Next, use an allen key to loosen the slots that the water bottle holder will fit into. Once loose, place the water bottle holder on the frame and tighten to secure.

12. Now that the bike is assembled, you can focus on adjusting the gears and brakes. While you can ride the bike without doing this step, it is not recommended. At this point, you could also take the bike to a service shop to have the gears adjusted, if needed.

13. Fill up the tires with air until they reach the proper pressure.

Your GMC Denali Road Bike is now ready to ride! Be safe and have fun. Make sure that you know the rules of the road before heading out, such as how to signal to drivers and when it’s safe to cross streets.

If you’re heading out to a more natural setting, make sure that you have water and a cell phone should you need to call for help.

There are also a few maintenance tips you should be aware of for GMC mountain bikes. Make sure that you’re lubricating the chain, brake calipers and brake levers on a weekly basis.

You should also lubricate shift levers every month and check the brake cables at least twice a year.

If you ride your bike just about every day, make sure that you check the wheel and pedal tightness, tire pressure, brakes and spokes before each ride. It also doesn’t hurt to wipe down the bike with a damp cloth at the end of each day to keep it looking its best.

If you need a bike that can handle just about anything you throw at it, check out the GMC Denali Road Bike. It’s one of my favorite bikes and you’re sure to love it, too.
