Mountain Bike Lingo

Have you ever been at a trailhead, unintentionally eavesdropping on a conversation between a group of mountain bikers and had no idea what they were talking about? Sometimes MTB-speak can sound like a completely different language. That’s why we’ve put together a list of common terms so you can decipher mountain bike jargon the next time you're at the bike shop or on your next ride.

Mountain Bike Dictionary

  • Bail: Getting off your bike as quickly as possible (and by any means necessary) to avoid a potential crash.
  • Berm: A banked turn. Learn how to ride berms HERE>
  • Bike Park: An area with progressive mountain bike features and downhill-focused trails that can be easily ridden repeatedly either by using a chair lift, shuttle system or climb return trail. Bike parks can be private, where you have to pay to access the trails, or public. Learn more about bike parks HERE>
  • Bonk: 
    1. (verb) To run out of energy (fuel) during a mountain bike ride or race. “I bonked so hard on that climb.” Learn how to avoid bonking HERE>
    2. (noun… or verb) A mountain bike jumping technique where you tap a feature with only the front wheel. “Watch while I attempt to do a nose bonk on that tree stump.” “You totally nose bonked that table top.”
  • Bunny Hop: A mountain bike skill where the rider lifts their front wheel, followed by the rear wheel into the air so both wheels are in the air at the same time. Learn how to bunny hop on your mountain bike HERE>
  • Case: To come up short on a mountain bike jump or drop. Casing can sometimes, but not always, lead to a crash.
  • Clean: Successfully making it over an obstacle in the trail without putting a foot down or falling off your bike. “I just cleaned that technical climb for the first time.”
  • Clear: To land smoothly when jumping a table top, double, or landing a drop. 
  • Clipless: Refers to clipless pedals and shoes, where a cleat on the bottom of a rider’s shoe is attached to a spring-loaded mechanism on the pedal. Also referred to as “clipped in” or “clips”. Originally, riders would “clip in” to their pedals using a caged pedal with straps around their shoes, also known as toe clips. When the spring-loaded pedals and cleats came about, these were referred to as “clipless” because they did not use toe clips.
  • Cross Country: Cross country (also referred to simply as XC) is a form of mountain biking where covering distance is emphasized over technicality. Cross country does not literally mean “across country.” Get XC MTB tips HERE>

  • Dab: To take a foot off the pedal and put it down to avoid crashing. “I haven’t made it through that section without dabbing yet.”
  • Double: A mountain bike jump that has two distinct mounds – a “lip” that helps launch a rider into the air and a “landing” where the rider is aiming to set their wheels down. A double can also be referred to as a “gap jump”, because there is a gap between the take-off and landing. Casing a double is likely to result in a crash. Learn how to jump HERE>
  • Downhill: Downhill (also referred to as DH) is a form of gravity-fed mountain biking where there is little to no uphill riding involved. Downhill trails are accessed by chair lifts or a shuttle.
  • Drop: A trail feature where the rider must launch their bike off of a height and land on a lower surface. Drops can be man-made or natural and consist of dirt, wood, rocks or roots as the take-off and/or landing. Learn how to ride drops HERE>

  • Dropper: Short for “dropper seatpost”, which is a height adjustable seatpost. Droppers enable a rider to quickly lower their seat height with the push of a lever mounted to the handlebars.
  • E-MTB: Electric mountain bike. E-MTBs are powered by a rechargeable battery which operates a motor that provides an adjustable boost of power when the rider pedals. Learn more about E-MTBs HERE>
  • Endo: An advanced mountain bike skill that involves shifting your body weight forward as you apply the front brake to lift the rear wheel. Endo turns can be used to navigate tight downhill switchbacks. Performing this skill on flat ground while coming to a stop is referred to as a “stoppie”.
  • Enduro:
    1. (noun) A form of mountain bike racing that is broken up into timed stages that are mostly (if not completely) downhill. Transfer/ climbing stages are not timed, but racers could be required to meet a cut-off. Events can vary in length and difficulty.

  • Squirrely: Riding a mountain bike without much skill or control. Also known as “sketchy”. “I got really squirrely over that wet root and thought I was going to crash!”

Mountain bikes with only front suspension are called “hardtails”. A mountain bike with both front and rear suspension is called a “full suspension”. Riders typically refer to their bikes by how much suspension it has, which is known as the “travel” (travel is usually measured in millimeters). “I have a full suspension mountain bike with 140mm of travel in the rear and a 150mm fork.” Learn more about suspension and how to adjust it HERE>
