PICTORIAL GLOSSARY

Bike Set Up

Our internationally certified coaches are mentored by Trailhead Coaching founder Jo Wall (who trains and certifies coaches in Australia). Professional, dynamic and community focused – owned and operated by women, driven by professional industry standards and up-to date teaching content.

Our programs and sessions cater for those starting their off-road riding journey through to advanced riders with options for group and private coaching – all tailored for each rider’s ability and goals.

Mountain bikes come in all shapes and sizes, particularly as kids start out and progress on their riding journey and grow into new bikes! Bikes and equipment is always a consideration that we factor in when determining the content, goals and how we teach particular skills. 

Below you will find some information which is aimed to inform you of options, various set ups and also their pros and cons for learning the skills of mountain biking. We hope you find it useful!

Wheel Sizes

Balance Bike &nbsp&nbsp :

12″ Balance Bike

We are huge advocates of all kids start their riding journey on a balance bike!

Balance bikes have revolutionised learning to ride bas they develop the most fundamental skill of stability and balance. Young riders can remain on a balance bike until they are ready to transition to the next wheel size 14, or 16 inch pedal bike. Kids who develop the ability to ‘glide’ on a balance bike will make a really smooth and quick transition to pedalling and using brakes. 

12″ Pedal Bike

Sometimes transitioning to a 12inch pedal bike can be good for those kids who are ready for the challenge of pedalling and braking while remaining on the same wheel size, one less variable!

More often than not kids will outgrow this wheel size very quickly and will most likely be tall enough to transition to a larger wheel size ie 14 or 16inch, but sometimes this jump in wheel size plus the need to master pedalling and braking can be a big jump. 

Single speed fixed gear with back pedal brakes
Fitted with hand operated front brake. This is a rim brake.

16″ Pedal Bike

The step up to a 16inch bike will definitely involve the need to master pedalling and also the use of pedal or back brake to control speed. These bikes will generally have a hand operated front brake, also. This wheel size will generally be a single speed fixed gear bike, so can be limiting when accessing varied terrain, particularly changes in gradients.

Pedal brakes can be a little tricky when instructing kids to ride off road, but witch careful instruction it can be done!. 

  • The back brake will very easily loose traction which can lead to a lack of control on loose surfaces and slower stopping distances.
  • When we teach children to stand up on ‘level pedals’ for stability and balance, it can be tricky to find the sweet spot to be stable without engaging the brake unintentionally.

Commonly called a ‘Hardtail’ as it has front suspension but no rear suspension. From a skill perspective we encourage kids to learn the fundamentals on a hardtail as they have to use their skills to smooth out the trail. Dual suspension bikes can also be a lot heavier for smaller riders.
This is a hydraulic disc brakes. Disc brakes are easy to use, requiring less finger strength for kids, they are more powerful/effective and reliable in wet conditions.

24″ Mountain Bike

Most 24″ MTB’s will have

  • Between 6-10 gears. Most bikes will have a single chain ring on the front but some may have 2 or 3 of they are a little older. If a bike has more than one chain ring on the front it will have dual gear controls ie. an up and down shift mechanism on each handlebar. From a skills perspective it is much simpler to have the one front chain ring and hence on gear shifter on the right hand handlebar.
  • If they are a dedicated off road bike they will have front suspension but may also be ‘fully rigid’ with no suspension.
  • 24″ frames may have enough room and or the bolts to mount a drink bottle cage. This is a requirement of all our older riders to be able to carry their own water. 

26″ Mountain Bike

The step up to a 16inch bike will definitely involve the need to master pedalling and also the use of pedal or back brake to control speed. These bikes will generally have a hand operated front brake, also.

This wheel size is sometimes referred to as 650B

27.5″ Mountain Bike

The step up to a 16inch bike will definitely involve the need to master pedalling and also the use of pedal or back brake to control speed. These bikes will generally have a hand operated front brake, also.

29″ Mountain Bike

This is now the most common wheel size for adult MTB’s. The benefit of 29″ wheels is that they more easily maintain their momentum once at speed, the larger wheel size means more of the tread pattern engages with the surface and provides better traction, and they can really help smooth out rocky terrain, less likely to get caught in the smaller depressions in the trail.

This bike is a dual suspension, as it has both front and rear suspension. 

This bike also has a dropper post, which allows the rider to lower and extend the seat. This creates more range of movement for the rider when they are travelling through corners, rough and or steep terrain.

Bike Components

Dedicated Off Road Tyres

Mountain Bike tyres will have loads of treat with pronounced knobs which provide good grip. This tyre is also a wider profile tyre which acts like suspension and provides great stability on kids bikes.

Front Suspension

A bike is commonly called a ‘Hardtail’ if it has front suspension but no rear suspension. From a skill perspective we encourage kids to learn the fundamentals on a hardtail as they have to use their skills to smooth out the trail. Dual suspension bikes can also be a lot heavier for smaller riders.

Disc Brakes

This is a hydraulic disc brake. Disc brakes are easy to use, requiring less finger strength for kids, they are more powerful/effective and reliable in wet conditions.

Rim Brakes

Gear Shifters – ‘Grip Shift’ and Paddle/Levers

Gears and Chain Rings

Dropper Seat Post

Flat Pedals

Clipless Pedals
