Mongoose Rockadile 20

Mongoose's Rockadile 20 bike is designed as an all-round, versatile kids bike.

This preview will explain who should consider buying the Rockadile 20, what it's designed for and a bit more about what components it has.

Who should consider buying the Rockadile 20?

First, the age.

It's called the Rockadile 20 because it's a 20-inch bike. This means the diameter of the wheels are 20-inches.

20-inch bikes are designed for riders who are at least 6 years (or very tall 5 year olds).

Next, the experience or co-ordination level.

Mongoose designed the Rockadile 20 to have 7 gears. And no foot brake. Braking and speed control is done only by the hands.

Even if your child is a little conservative and hasn't used gears or hand brakes before, kids learn really fast.

It's simply a case of explaining what to do and not to do when shifting gears. And a little a bit of practice.

What is the Rockadile 20 used for?

Mongoose designed the Rockadile 20 to be an all-rounder kids mountain bike.

Meaning it's comfortable on pavement, rougher suburban bike paths, rail trails, smooth dirt and gravel paths.

The Rockadile's front suspension smooths out any bumps and impacts.

Suspension also adds stability to the front steering; making the Rockadile 20 calmer and easier to control.

Some key components.

The Rockadile 20 uses a Shimano 7 speed gearing system. It's a twist-grip setup.

Riders don't need to take their fingers off the handlebar to change gears. Full hand coverage over the handlebar and shifter means better bike control; especially as kids don't have big hands.

7 gears allows riders to easily climb steeper inclines and efficiently cover distance on longer bike rides.

The small black sprocket is gear 7. It's the hardest gear to push but will deliver the highest top speed. Use this for going downhill.

And the largest silver sprocket is the easiest gear (gear 1); best used to going up steep inclines.

For flat terrain, gear 4 is ideal (pictured).

The Rockadile 20 doesn't have any foot brakes. Riders now have to use their hands to slow down.

The left hand lever controls the rear brake. Right lever controls the front brake.

Modern V-brakes or linear pull brakes are used on the Rockadile 20.
