Mountain bikes are built to ride off the road which means they’ll get dirty rather quick.
- Get a spray bottle, fill it with water (or soapy water)
- Spray the bike
- Let it sit for a minute
- Use a cloth to sweep off the dirt
- Use an old toothbrush to clean those difficult spots
- Once the frame & wheels are clean, use the cloth to clean the derailleur sprockets and the chain
- Lastly, clean the chain
*Avoid pressure washer as this can ruin the seals and allows the water get to places where it shouldn’t be. Mountain bikes are not waterproof to a degree of submerge.
*Some riders use a thin layer of universal oil on the clean frame as it will give an extra layer on the bike, and the dirt will come off easier next time.
Yes, you can ride mountain bikes on all surfaces, including tar, pavement and concrete, and it’s legal to ride a mountain bike on any road that allows bicycles.
However, mountain bikes are slower and heavier to cycle on pavement, so if you plan to ride mostly on the road, you should rather get a hybrid or road bike.
- Slower
- Good mountain bike tires are quiet expensive, and some use a softer compound which wears out way quicker than it would on the road.
To change a mountain bike tire, you’ll first need to find out if it’s a tubeless tire or not.
Tubeless tires don’t use inner tubes but have a glue sealant around the rim to make them airtight. However, if you don’t have sealant, you can fit any tubeless tire with a spare inner tube.
First, remove the wheel that needs changing and let all the air out of the tire. Then, loosen the bead along the side of the tire so it pops off the rim. If there’s an inner tube, you may need to unscrew the washer, holding the valve in place before removing the tube.
Check the inside of the tire for glass, thorns or debris that may have caused the puncture. If the damage to the tire is not too bad, you can salvage it and just replace the inner tube. Either patch the damaged inner tube with a puncture repair kit or, preferably, replace it with a new tube.
Slip one side of the tire back onto the rim and then slip the new inner tube into the tire, lining up the valve with the hole so you can insert it. Once in place, pump up the inner tube slightly but not all the way – this will fill it out, so it stays in place inside the tire.
Now, you can push the other side of the tire onto the rim with your thumbs, making sure not to pinch the inner tube. Once in place, pump up the inner tube completely and you’re ready to go.
You should replace your mountain bike tires when the strip along the center of the tire starts to go smooth. Without grip on this section, you won’t be able to brake as quickly and could be in an accident.
Uneven weight distribution means the rear tire on a mountain bike wears out faster than the front, so you’ll find it getting smooth sooner. What many riders don’t realise is that you can just swap the front and rear tires when the rear tire’s tread wears smooth and ride the same distance again before buying replacements.
Mountain prices vary greatly, with some costing as little as $100 and others reaching $10,000 or more. However, the average cost of a decent mountain bike is about $1,000. Bikes below this level are likely to be of an inferior quality.
Modern mountain bikes usually have complex frames built from expensive materials with several components and moving parts.
Add to this the cost of brakes, gears, shocks and suspension systems, all of which need to be built from high-quality materials to withstand tough conditions.
Mountain bikes weigh anything from 20 lbs (9kg) to 40 lbs (18kg), with the average weight being around 30lbs (14,6kg).
In general, the lighter the mountain bike, the more expensive it will be because lightweight materials cost more to produce.
Mountain bikes that use hydraulic disc brakes need to be bled from time to time.
This involves leaking fluid from the braking system and pushing new fluid through it in order to remove bubbles. You do this by removing the brake pads and using a syringe filled with hydraulic mineral oil to bleed the fluid.
Most mountain bikes come assembled but sometimes, you may need to put it together yourself.
To do this, you’ll need several tools including Allen keys, wrenches, and screwdrivers of varying sizes.
Basic assembly typically involves attaching the wheels, pedals, seat post and handlebars. You can secure the handlebars to the headset with a small Allen key, ensuring the brake levers and gears are level. For the rear wheel, you’ll need to pull the chain around the cassette before slotting the wheel in. Most mountain bikes now use a thru-axle, secured by a large Allen key.
Pedals screw on and can be tightened with a wrench, while the seatpost typically slots in and secures with a quick-release bolt.
We have compiled a rough estimation, but recommend ALWAYS checking the correct manufacturers size guide. If you happen to fall in two bike sizes – check out our guidance article about that.

5’10” – 6’1″ | 178cm – 185cm | 31″ – 33″ | 19″ – 20″ | (L) | 5’10” – 6’1″ |

Electric Mountain Bikes
Electric assist mountain bikes, or e-MTBs, amplify the power you put into the bike while pedaling. When you stop pedaling, the motor stops assisting. You still have to earn your fun, but you get a better return on your energy investment.
Electric mountain bikes have a small motor under the frame where the cranks are. A rechargeable lithium-ion battery powers the motor. The motor only provides power when you are pedaling. It adds power to each of your pedal strokes, so it feels like pedaling a normal bike, except with supercharged legs. You can control how much power the motor provides with a handlebar-mounted remote. Trek e-MTBs with Bosch drive systems let you choose from three different levels of assist power. Or you can use the set-and-forget e-MTB mode that automatically adjusts the assist to deliver just the right amount of power for every situation on the trail.
E-bike range depends on several factors. Battery size, motor efficiency, rider weight, terrain, and even temperature can affect how far your e-MTB will go on one battery charge. Basically, the harder the motor has to work, the more battery power it will use. The more power it uses, the faster the battery runs out. That’s why larger riders tend to get less range than smaller riders, and why a ride on hilly terrain with a lot of sustained climbing will deplete the battery faster than a flatter ride with less climbing. To estimate how far you can ride an electric mountain bike on a single charge, check out Bosch’s range calculator.
Pedal assist mountain bikes will go as fast as your legs turn the pedals. However, the motor will stop assisting once a certain cut-off speed is reached. Generally, that cut-off speed is 20 miles per hour in North America, and 25 kilometers per hour in Europe. Above these speeds, you can keep pedaling the bike, but the motor will not provide additional power.
Regulations on where e-mountain bikes can be ridden vary by region. Generally, electric mountain bikes are approved for use on trails that allow motorized or pedal-assist vehicles. Many traditional mountain bike trails do not allow e-bikes, so it’s important to check with your local land management authority or trail owner before you ride.
While electric mountain bikes are super fun and can help you enjoy your favorite trails even more, they’re not allowed everywhere. Check the rules for the trails you plan to ride. If they don’t specifically allow pedal-assist bikes or motorized vehicles, then an e-MTB may not be your best choice.
There’s a lot more to an e-bike than the motor. With Trek, you’re getting a legit mountain bike that’s developed with the same frame and suspension tech that makes our regular bikes so much fun to ride. Plus, we’ve focused our efforts on delivering the best e-bike experience possible so you can enjoy a ride that minimizes hassle and maximizes confidence.
