When it comes to choosing your first mountain bike, there’s so much choice and to a newbie, it can feel overwhelming. They might all look the same but can be very different in terms of quality, performance and rideability.

Depending on what you’ll be using your bike for, you’ll need a mountain bike that can keep up - whether that’s going on leisurely weekend trails to exploring nature or tearing down a mountainside at top speed.

To make it a bit easier, we’ve put together this easy beginner guide to answer all your questions and help you choose the right mountain bike for you.


What is the best mountain bike?

There isn’t just one answer to this question.

Depending on your requirements, a bike designed for racing cross-country isn’t the same as a one for trail riding on a weekend.

When choosing a bike, there’s some important things to keep in mind:

  • Try to avoid full suspension bikes - they will be super heavy which will affect the quality of the ride.
  • Avoid buying your bike from a supermarket/catalogue - they’re likely to be poor quality and the best choice of trail riding.
  • Opt for aluminium frames rather than steel or chromoly – they will be much lighter and easier to handle.
  • Choose hydraulic disc brakes if possible.
  • Try to get air-sprung suspension forks – this makes it easier to set the bike up to your body weight.
  • Choose a Shimano or SRAM drivetrain, preferably with a single chainring up front and wide-range cassette at the rear.

How much should I spend on my first mountain bike?

Even though some supermarkets and catalogues retailers sell ‘mountain bikes for as little as £100, bikes at this price just aren’t up to the job.

They’re likely to have weak, heavy, low quality steel frames rather than a lightweight premium aluminium one, fitted with poor quality components that won't last very long if you’re riding it off road on challenging trails.

If you set your budget at around £400, you'll end up with a bike that can deal with most of the different terrains without falling apart after a couple of uses. However, the more you invest, the more likely it is that your bike will more suited to your needs.

It’s worth investing a little more money in the beginning to guarantee a good experience and quality product. The last thing you want is your bike breaking miles away from anywhere and then having to spend more money to get it repaired.


What size mountain bike do I need?

When it comes to choosing the right size bike, especially if it’s your first one, can be tricky. Most manufactures will provide a size guide but it’s always best to visit a reputable bike shop. They’ll be able to help find the right one for you and answer any questions you might have.

It’s always recommended to try and get the largest frame you can which still allows enough ‘stand over’ - this is the remaining space between you and the top of the bike frame when you’re standing over it with both feet on the floor.

If you choose a bike frame that’s too big, it can lead to you being in an uncomfortable stretched out riding position. If the frame is too small, you’ll feel cramped and feel nervous when riding, with a less than ideal efficient pedalling position.


What size wheels do I need?

Depending on who you ask, you’ll get a different opinion from each person, but 29-inch wheels seem to be the most common size on new mountain bikes at almost every price point.

This size wheel can compensate a lack of sensitivity in the fork while providing more stable handling which is ideal for a beginner.

Regardless of size, decent quality tyres can make a huge difference to how the bike rides. If you're going to be riding on dirt tracks, choose an aggressively knobbly tread for extra grip or a light treaded tyre if you’re planning on cycling on hard flat surfaces.


How many gears do I need?

Choosing a bike with a drivetrain that provides a wide range is important to good off-road performance. If you opt for a smaller sized front chainrings and a cassette with bigger sprockets at the rear, this will give you plenty of range to get up steep hills without too much extra effort.

Many entry-level bikes will only have a seven-speed cassette, but most rider prefer to go with eight, nine or even ten-speed blocks but they are more expensive to purchase.



What brakes should I have on my bike?

If you’re planning on spending a lot of time riding in our famous British weather, making sure you have a set of brakes that still work perfectly when they're wet in a must!

Car-style disc brakes fitted to the hub of the wheel are much better than a set of cheaper rim brakes. They’ll keep working regardless of the conditions and without wearing out your rims over time.

If you have a bit more to spend, then it’s worth opting for disk brakes that use hydraulic fluid to operate. This style of brake is good as they require very little maintenance and offer better stopping power.


Is there anything else I need to know?

Obviously, a comfortable seat should be at the top of list if you want to be as comfortable as you can on those longer rides.

Don’t be fooled into thinking bigger is better as large seats with lots of padding can often be more uncomfortable than slim, better-shaped ones.


Can you ride a mountain bike on the road?

Yes – but where’s the fun in that?


Can I use a mountain bike on a turbo trainer?

For those days when you can’t get out on the trails but still want to ride your bike, hooking it up to a turbo trainer is the next best thing.

Most direct drive trainers are compatible with mountain bikes if you have the correct adapters for your bike and a cassette that is compatible with the drivetrain on your bike.
