What Age Is the Amped A18 Comp For?
The Amped A18 Comp is typically best suited to confident riders aged around 7–13 who want serious full-suspension performance but still need a more manageable bike than the larger A20 Comp.
What age child can ride an Amped A18 Comp?
The Amped A18 Comp is generally best suited to confident riders aged approximately 7–13 years old, with a recommended rider height of roughly 120–150cm.
Height and riding experience are more important than age alone. The A18 Comp is a serious performance bike with full suspension, hydraulic brakes and an 800W motor, so the rider should already have reliable balance, throttle and braking control.
It is the most manageable entry point into the Amped Comp range and makes particular sense when the rider wants more capability than the Amped A20 Pro but does not yet need the larger A20 Comp.
Where does the A18 Comp sit in the range?
The Amped A18 Comp is the smallest and most manageable model in the premium Comp line-up. It delivers the suspension, braking and serious off-road feel of the Comp range without requiring the rider to manage a larger 20-inch or 24-inch chassis.
Experience matters more than the number on the birthday card
Being tall enough for the A18 Comp does not automatically mean a rider is ready for it. The correct rider should combine a suitable physical fit with confidence and reliable control.
Physical Fit
The rider should be able to support, steer and reposition the bike without becoming physically overwhelmed by its size or weight.
Throttle Control
They should already understand how to accelerate smoothly rather than suddenly applying full throttle from a standstill.
Braking Ability
The rider should be able to release the throttle and use the hydraulic brakes progressively without panicking or locking up.
Who is the Amped A18 Comp best suited to?
The A18 Comp should suit riders who:
- Are typically around 7–13 years old
- Are approximately 120–150cm tall
- Already ride confidently on two wheels
- Have reliable throttle and braking control
- Want a premium full-suspension electric bike
- Have outgrown smaller starter-style machines
- Still benefit from an 18-inch platform
- Will ride on tracks, fields and suitable off-road terrain
- Will be closely supervised by a responsible adult
Consider a different model when:
- The child is a nervous or complete beginner
- They are below approximately 120cm tall
- They cannot support the bike securely
- The A20 Pro already provides enough performance
- They are still learning basic throttle control
- They need a lighter or more beginner-friendly bike
- They are approaching 150cm and growing quickly
- The larger A20 Comp provides a better physical fit
How powerful is the Amped A18 Comp?
The Amped A18 Comp uses a 36V 800W brushless rear hub motor with peak output of up to approximately 1000W.
It is powered by a removable 36V 10Ah lithium battery and can reach speeds of up to approximately 25mph, depending on rider weight, terrain, battery charge and riding conditions.
Full suspension and hydraulic disc brakes help make the additional performance more controlled over grass, tracks and uneven off-road surfaces.

Is the Amped A18 Comp suitable for beginners?
The A18 Comp is not primarily designed as a first electric bike. It is a progression model for riders who already have reasonable experience and confidence.
A physically suitable beginner with strong pedal-bike experience may be able to learn progressively under close adult supervision, but many first-time riders will be better suited to the Amped A20 Pro or a more manageable Revvi model.
- Begin on the lowest suitable performance setting
- Use a large, flat and controlled riding area
- Practise smooth throttle application
- Practise releasing the throttle before braking
- Introduce rougher terrain gradually
- Use a properly fitted helmet and protective equipment
- Provide close adult supervision throughout
Is the Amped A18 Comp too powerful?
It may be too powerful for a nervous, inexperienced or physically small rider. The A18 Comp offers significantly more capability than a basic electric balance bike and should be treated as a serious off-road machine.
For a confident rider with good control, the combination of selectable performance settings, hydraulic brakes and full suspension provides plenty of room for gradual progression.
Can a seven-year-old ride an Amped A18 Comp?
A tall and highly confident seven-year-old may suit the A18 Comp, especially if they have already progressed from a smaller electric bike.
Many seven-year-olds will still be better suited to the A16 Pro, A20 or A20 Pro. The rider should be close to the recommended height range and capable of supporting the bike without assistance.
Can an eight-year-old ride an Amped A18 Comp?
Yes. The A18 Comp can be an excellent option for a confident eight-year-old who is physically ready for an 18-inch full-suspension bike.
A nervous or smaller eight-year-old may find the A20 Pro or Revvi 18 easier to manage while developing confidence.
Can a nine or ten-year-old ride an Amped A18 Comp?
Yes. Nine and ten years old often sit within the strongest general suitability range for the Amped A18 Comp.
For confident riders around 120–145cm tall, the A18 Comp provides serious performance while remaining more compact and manageable than the A20 Comp.
Can an eleven or twelve-year-old ride an Amped A18 Comp?
Yes, provided the rider still fits the bike comfortably. The A18 Comp can suit many eleven and twelve-year-olds who prefer a compact, agile bike rather than a larger chassis.
Riders approaching the upper end of the height range should also compare the A20 Comp before buying.
Can a thirteen-year-old ride an Amped A18 Comp?
A smaller thirteen-year-old may still fit the A18 Comp, particularly if they value agility and a more compact riding position.
Taller riders approaching or exceeding approximately 150cm are likely to gain more comfort, stability and growing room from the A20 Comp or A24 Comp.
How long will a child fit the A18 Comp?
The recommended rider-height range of approximately 120–150cm provides useful growing room for children entering near the lower or middle part of the range.
A rider who is already close to 150cm may have less time before the A20 Comp becomes the more comfortable option. However, a smaller rider will normally progress better on a properly fitting A18 Comp than on an oversized A20 Comp.

How to check whether the Amped A18 Comp fits
A suitable rider should appear naturally positioned and remain capable of controlling the bike when stationary, moving slowly and braking.
Check foot contact
The rider should be able to place their feet down securely enough to support the bike when stopping and moving at low speed.
Check handlebar reach
They should hold the handlebars naturally and operate the throttle without leaning excessively forward or locking their arms.
Check brake reach
The rider must be able to reach both hydraulic brake levers and apply them progressively while maintaining a secure grip.
Check overall control
Physical fit alone is not enough. The rider should already understand steering, throttle control, braking and safe stopping.
