Amped A20 Electric Balance Bike – Quick Overview
Best for: riders aged approximately 6–12+ years old.
Ideal rider height: riders around 120–145cm.
Seat height: approximately 65–75cm.
Motor: 540W electric motor.
Ride modes: Eco 9.3mph / Boost 19.8mph.
Why parents choose it: larger 20” platform, smooth power delivery and more room to grow than smaller Amped models.
Our view: a brilliant progression bike before stepping into full Pro-level performance.
The Amped A20 is the natural step up from smaller Amped electric bikes. It gives riders more size, more power and more room to grow, without jumping straight into the more aggressive A20 Pro.
With a 540W motor, 20” platform, direct-drive rear hub motor and two simple ride modes, the A20 is built for progressing riders who want a bigger, smoother and more capable electric bike.
In terms of sizing, the Amped A20 is best suited to riders around 120–145cm tall. This makes it a strong choice for children who have outgrown smaller 16” bikes but may not need the extra aggression of the A20 Pro.

My Take as a British MX Rider
The Amped A20 is where kids electric bikes start feeling much closer to a proper lightweight off-road bike rather than just a smaller balance bike with power.
The bigger 20” platform, smooth direct-drive setup and stronger overall feel make it a confidence-inspiring progression bike for riders stepping up from smaller models.
The key sizing point is height. If the rider is around 120–145cm tall, the A20 is a great fit. If they are already towards the taller end and very confident, the A20 Pro may be worth considering instead.
For most riders aged around 6–12+ and around 120–145cm tall, this is one of the best all-round progression bikes in the Amped range.

Direct Drive. Silent. Low Maintenance.
The rear hub motor on the Amped A20 is a direct-drive system, meaning power goes straight to the back wheel with no chain, no sprocket wear and virtually no mechanical noise.
This creates a cleaner, quieter ride with less maintenance and less to adjust over time.
Combined with 28Nm of torque, acceleration feels smooth, predictable and confidence-inspiring rather than aggressive or intimidating.
Battery, Range & Ride Time
The Amped A20 uses a removable 36V 5.0Ah lithium battery, providing approximately 45–60 minutes of ride time per charge.
Eco mode significantly extends battery life compared to Boost mode, making it ideal for younger or less experienced riders.
Charge time is approximately 3–6 hours using the included 36V 2A charger.
