What Age Is the Amped A20 Comp For?
The Amped A20 Comp is typically best suited to confident riders aged around 7–14 who want a premium 20-inch electric bike with serious power, full suspension and proper long-term off-road progression.
What age child can ride an Amped A20 Comp?
The Amped A20 Comp is generally best suited to confident riders aged approximately 7–14 years old, with the strongest overall fit commonly found among riders around 130–160cm tall.
Age is only a guide. The rider must also be physically large enough to manage a 20-inch full-suspension bike and experienced enough to control a 1000W motor, hydraulic brakes and speeds of up to approximately 28mph.
It sits between the smaller Amped A18 Comp and the larger Amped A24 Comp , making it the best all-round Comp model for many confident young riders.

Where does the A20 Comp sit in the range?
The A20 Comp is the middle model in the premium Amped Comp line-up. It gives riders more size, stability and performance than the A18 Comp while remaining substantially more manageable than the larger A24 Comp.
Height and experience matter more than age
Two children of the same age may need completely different bikes. The correct A20 Comp rider should combine a suitable physical fit with confidence, strength and reliable riding control.
Physical Fit
The rider should be able to support, steer and reposition the 23.2kg bike without becoming physically overwhelmed by its size or weight.
Throttle Control
They should already understand smooth acceleration and avoid suddenly applying full throttle while starting, turning or riding over uneven terrain.
Braking Ability
The rider should be able to release the throttle and apply the front and rear hydraulic brakes progressively without panicking.

Who is the Amped A20 Comp best suited to?
The A20 Comp should suit riders who:
- Are typically around 7–14 years old
- Are approximately 130–160cm tall
- Already ride confidently on two wheels
- Have reliable throttle and braking control
- Have outgrown smaller starter-style electric bikes
- Want a serious 20-inch off-road platform
- Need full suspension for tracks and rougher ground
- Want more capability than the A20 Pro
- Still benefit from a bike smaller than the A24 Comp
- Will ride under responsible adult supervision
Consider a different model when:
- The child is a nervous or complete beginner
- They are below approximately 130cm tall
- They cannot support the bike securely
- The lighter A20 Pro already offers enough performance
- They still need the smaller A18 Comp chassis
- They have not developed reliable braking control
- They are approaching 160cm and growing quickly
- The larger A24 Comp provides the better physical fit
How powerful is the Amped A20 Comp?
The Amped A20 Comp uses a 36V 1000W brushless rear hub motor with peak output of up to approximately 1200W.
It is powered by a removable 36V 10Ah lithium battery and can reach speeds of up to approximately 28mph, depending on rider weight, terrain, battery charge and riding conditions.
Its full-suspension setup includes a 100mm adjustable hydraulic front fork and a FASTACE rear air shock. XOD hydraulic brakes are fitted front and rear, while 20-inch Kenda fat off-road tyres provide stability and grip over suitable off-road terrain.

Amped A20 Comp speed modes explained
The A20 Comp includes three selectable speed modes, allowing its performance to be introduced gradually as the rider gains confidence and experience.
Up to 9.5mph
Best for initial sessions, learning the controls and becoming familiar with the bike’s size, braking and handling.
Up to 18.5mph
Suitable once the rider can accelerate, steer and brake consistently and is ready for stronger performance.
Up to 28mph
Intended for experienced, properly equipped and closely supervised riders using a large and controlled off-road area.
Maximum speed and range will vary according to rider weight, terrain, tyre pressure, battery charge and riding conditions.
Can parents limit the A20 Comp’s speed?
Yes. The three riding modes allow parents to introduce the bike’s performance gradually rather than giving the rider access to full speed immediately.
Initial riding should take place in Beginner mode within a large, flat and controlled area. Advanced or Sport mode should only be introduced when the rider consistently demonstrates smooth throttle, steering and braking control.
Is the Amped A20 Comp suitable for beginners?
The A20 Comp is not primarily designed as a first electric bike. It is a serious progression model for riders who already have good balance, confidence and reliable control.
A physically suitable rider with strong pedal-bike or off-road experience may be able to begin in the lowest mode under close supervision. However, the Amped A20 Pro or standard Amped A20 will normally provide a more accessible introduction.
- Begin in the lowest speed mode
- Use a large, flat and controlled riding area
- Practise smooth throttle application
- Practise releasing the throttle before braking
- Introduce bumps and rougher terrain gradually
- Increase speed only when control is consistent
- Use a properly fitted helmet and protective equipment
- Provide close adult supervision throughout
Is the Amped A20 Comp too powerful?
It may be too powerful for a nervous, inexperienced or physically small rider. The A20 Comp is significantly more capable than a basic electric balance bike and should be treated as a serious off-road machine.
For a confident rider who already understands throttle, steering and braking control, the three riding modes allow performance to be increased progressively.
Its hydraulic brakes and premium suspension help the bike feel controlled, but they do not replace responsible supervision, suitable protective equipment or sensible riding conditions.
Can a seven-year-old ride an Amped A20 Comp?
A particularly tall and highly experienced seven-year-old may suit the A20 Comp, but most riders of this age will still be better matched to a smaller model.
The child should be close to 130cm tall, physically strong enough to support the bike and already confident with powered off-road riding. The A18 Comp or A20 Pro will often be the safer and more manageable choice.
Can an eight-year-old ride an Amped A20 Comp?
Yes, a tall and confident eight-year-old may suit the A20 Comp, particularly if they have already progressed from a smaller electric bike.
Smaller or less experienced eight-year-olds should also compare the A18 Comp and A20 Pro before moving to the larger, heavier Comp chassis.
Can a nine-year-old ride an Amped A20 Comp?
Yes. The A20 Comp can be a strong choice for a confident nine-year-old who is around 130cm or taller and already has reliable off-road riding control.
Beginner mode provides a sensible starting point, but the child must still be physically comfortable with the size and weight of the bike.
Can a ten-year-old ride an Amped A20 Comp?
Yes. Ten years old often sits within the strongest general suitability range for the Amped A20 Comp.
For a confident rider around 130–150cm tall, it provides a strong balance of manageable sizing, serious power and enough capability for long-term progression.
Can an eleven-year-old ride an Amped A20 Comp?
Yes. The A20 Comp is an excellent option for many confident eleven-year-old riders, particularly those moving up from an A20 Pro, Revvi 18 or another smaller electric bike.
It offers more suspension, braking performance and chassis stability without immediately moving to the much larger A24 Comp.
Can a twelve-year-old ride an Amped A20 Comp?
Yes. Many twelve-year-olds will fit the A20 Comp extremely well, provided they fall within the approximate 130–160cm rider-height range.
A rider already approaching 160cm should also compare the A24 Comp, particularly if they are growing quickly and have the experience to manage the larger bike.
Can a thirteen-year-old ride an Amped A20 Comp?
Yes. The A20 Comp can suit many thirteen-year-old riders who remain comfortable on a 20-inch platform and prefer a more compact, agile bike.
Taller riders around 155–160cm may sit between the A20 Comp and A24 Comp. In that situation, current physical fit and riding confidence should take priority over buying the largest possible model.
Can a fourteen-year-old ride an Amped A20 Comp?
Yes, provided the rider remains within the recommended size range. A smaller fourteen-year-old may find the A20 Comp fast, capable and easier to handle than a larger 24-inch bike.
Riders approaching or exceeding 160cm are likely to gain more space, stability and long-term comfort from the A24 Comp.
How long will a child fit the Amped A20 Comp?
The recommended rider-height range of approximately 130–160cm gives the A20 Comp useful growing room for children entering near the lower or middle part of that range.
A rider who starts around 130–140cm may use the bike for several seasons, depending on growth rate and riding development. A rider already near 160cm may have less physical room to grow and should also compare the A24 Comp.
Amped A20 Pro vs Amped A20 Comp
Both bikes use a 20-inch platform, but the A20 Pro is the lighter, better-value performance option. The A20 Comp is the more substantial full-suspension bike for serious off-road progression.

Amped A20 Comp vs Revvi 20
The Revvi 20 and Amped A20 Comp are both premium 20-inch electric bikes, but they suit different rider priorities.
The Revvi 20 is the smoother and more confidence-building all-rounder. The A20 Comp is the stronger performance choice for riders who want full suspension, hydraulic brakes and a more aggressive off-road setup.
| Feature | Revvi 20 | Amped A20 Comp |
|---|---|---|
