Looking for one of the best 20” electric bikes for kids? The Amped A20 is a serious step up from smaller electric balance bikes, giving young riders a bigger platform, smooth power delivery and proper off-road capability — without jumping straight into full high-performance territory.
Quick answer: the Amped A20 is one of the best-value 20” electric bikes for riders aged around 6–12+. It gives a bigger bike feel, controlled power and proper progression without being too much too soon.
Quick Answer
Choose the Amped A20 if your rider is ready for a larger 20” electric bike with more stability, more room to grow and smooth usable power.
It is ideal for riders stepping up from smaller 12” or 16” bikes who want a bigger bike feel without jumping straight into full high-performance territory.
For many young riders, the A20 is the sweet spot between starter electric bikes and faster Pro-level machines.
My Take as a British MX Rider
The Amped A20 is a really strong progression bike because it gives riders more size and stability without becoming too aggressive too quickly.
It feels much more planted than smaller electric balance bikes, but the power delivery is still smooth enough for riders building confidence.
For a rider who has outgrown a 16” bike and is ready for a proper next step, the A20 makes a lot of sense.

Why Riders Love the A20
The A20 has a very different feel from starter electric balance bikes. It gives young riders a larger platform, more stability and a much more confidence-inspiring ride at speed.
More Room to Grow
The 20” platform gives taller and older riders more space than smaller electric bikes.
More Stability
The larger frame and wheel size help the bike feel more planted at speed.
More Progression
A strong stepping stone before moving into faster Pro-level electric bikes.
540W Performance with Two Ride Modes
The Amped A20 uses two riding modes so riders can build confidence before using the full performance of the bike:
- Eco Mode — around 9.3mph for controlled riding
- Boost Mode — around 19.8mph for full performance
This makes the A20 easy to start on, while still giving riders something they can grow into.
Direct Drive Motor — A Big Plus
One of the best things about the Amped A20 is its direct-drive rear hub motor. It keeps the bike quiet, simple and low maintenance compared with chain-driven options.
- No chain
- No sprocket wear
- Quiet power delivery
- Low maintenance design
- Smooth throttle response
For many families, that simplicity is a major reason to choose the A20.
Built for Progression
The A20 is not just about speed. It is designed to help young riders build proper riding skills and confidence before moving onto faster or more advanced bikes.
- Throttle control
- Cornering confidence
- Standing technique
- Off-road bike handling
- Skills that transfer to bigger bikes later
That is why many riders progress through the Amped range from A16 → A20 → A20 Pro.
Amped A20 vs A20 Pro — Should You Stretch?
If your rider is already confident or aggressive, the A20 Pro may be worth considering.
Choose the A20 If...
- You want a smooth, manageable step up
- Your rider is moving up from a smaller bike
- You want strong value
- You do not need maximum performance yet
Consider the A20 Pro If...
- Your rider is already confident and fast
- You want more performance
- You want longer-term progression
- You want the stronger overall specification
Who Is the Amped A20 Best For?
- Riders outgrowing 12” or 16” bikes
- Riders wanting a bigger bike without too much power
- Families looking for strong value in a 20” electric bike
- Young riders doing regular off-road riding
- Riders who need a bike they can grow into
The Amped A20 is best for confident young riders who are ready for more bike, but not necessarily ready for the full aggression of a Pro model.
