mountain bike

A mountain bike or mountain bicycle (abbreviated Mtn Bike, MTB; or ATB, for all-terrain bicycle) is a bicycle designed for off-road cycling. Mountain bikes share similarities with other bikes, but incorporate features designed to enhance durability and performance in rough terrain. These typically include suspension on the frame and fork, large knobby tires, more durable heavy duty wheels, more powerful brakes, and lower gear ratios needed for steep grades with poor traction.
Mountain bikes are typically ridden on mountain trails, fire roads, logging roads, single tracks and other unpaved environments. These types of terrain commonly include rocks, washouts, ruts, loose sand, loose gravel, roots, and steep grades (both inclines and declines). Mountain bikes are built to handle this terrain and the obstacles that are found in it like logs, vertical drop offs, and smaller boulders.
Since the development of the sport in the 1970s many new subtypes of mountain biking have developed, such as cross-country (XC) biking, all-day endurance biking, Freeride-biking, downhill mountain biking, and a variety of track and slalom competitions. Each of these place different demands on the bike requiring different designs for optimal performance. MTB development has included an increase in suspension, typically up to 8" or 203mm, and gearing, up to 30 speeds, to facilitate both climbing and rapid descents. However, advancements in sprocket design has recently led to the "1x (pronounced one by)" trend, simplifying the gearing to one Chainring/Sprocket in the front and multiple sprockets on the rear of the drive train, more commonly, 9, 10 or 11 .

    Mountain Bike help ?

    I’m looking at a mountain bike for my son who is going to be 10 and is 150cm tall. I’d ideally like something that is going to last and not going to be scrap in about a year. I was looking at a Rockrider ST 100 for around £200 but in all honesty it’s a bit of a minefield. I think budget is...

    £500 mountain bike for my son?

    He's currently got a 24" wheel Genesis Core, but at 4'11", he's just starting to outgrow it. Looking for a small adult bike, 26 or 27.5" wheels, hydraulic disc brakes, front suspension, etc. Had anyone got any recommendations please?
  5. Autopilot

    Recommend me a new mountain bike for under £1k please.

    Any recommendations here for the best mountain bike under a grand? (probably a hard tail). Not done a lot a mountain biking for a few years since I was younger, bit of road biking in recent years, but live in a area far more suited to MTB now. Won’t be doing any too crazy, mostly just trails...

    Stolen Whyte 46 Mountain Bike From CV Area

    A little over a year after my previous bike was stolen, it's happened again. To say I'm angry is an understatement, so if I find out who it is, I might invest in a new drill for "extra curricular" activities... Like my previous bike, it is unique. There are other bikes out there, but more often...
