My Take as a British MX Rider

20 inch bikes are where young riders often start to feel real progression.

This is where I start thinking less about “starter bikes” and more about what will actually help a rider improve.

If I was choosing based on progression first, I’d focus on confidence and control before chasing maximum power.

Best First 20” Step-Up Bike

The Amped A20 is a brilliant step into larger bikes without going straight into higher-performance territory.

• 540W motor
• Up to 20mph
• Manageable power delivery
• Great first 20 inch step-up bike
• Good progression from smaller Amped models

My view: one of the smartest step-up bikes in the 20” category.

Best for Older or Taller Riders

The Revvi 20 is one of the most popular 20 inch electric bikes for kids in the UK.

• 800W motor
• Up to 22mph
• Smooth, confidence-building ride
• Strong larger-platform option
• Great for older or taller riders

My view: probably the safest “can’t go wrong” recommendation for riders wanting a bigger, smooth and stable 20” bike.

Best Performance-Per-Pound Choice

The Amped A20 Pro pushes further than most bikes in this category while still offering strong value for the spec.

• 800W motor
• Up to 28mph
• 36V 10Ah battery
• Hydraulic brakes
• Hydraulic adjustable forks
• Huge upgrade potential

If performance and long-term headroom are the goal, the A20 Pro is very hard to ignore.

Best Premium Amped 20” Option

The Amped A20 Comp is a serious step up from standard 20 inch electric bikes.

It is not just a slightly better A20 Pro — it moves into a more complete off-road performance setup with more motor output, full suspension and a much more capable chassis.

• 36V 1000W brushless motor
• 1200W peak output
• Up to 28mph
• 36V 10Ah battery
• 60–90 minutes ride time
• Double shoulder hydraulic adjustable front forks
• FASTACE rear air shock
• XOD hydraulic brakes front and rear
• 20” Kenda fat off-road tyres

My view: the A20 Comp is the premium Amped choice for riders who want more serious off-road performance than the A20 Pro.

Compared with the STACYC 20eDRIVE, I would position the A20 Comp as slightly more aggressive and off-road focused, while the STACYC feels more premium, lightweight and refined.

Best Premium Lightweight Option

The STACYC 20eDRIVE takes a different route to traditional electric dirt bikes — lighter, premium and hugely skill-focused.

• Premium 36V brushless STACYC platform
• Up to 20mph
• 40Vmax 6Ah battery
• Manitou J-Unit Machete forks
• Hydraulic brakes front and rear
• Lightweight 15kg package
• Premium no-compromise build quality

It is a more specialist choice than the Revvi or Amped options, but for the right rider it is a seriously premium machine.

My view: if budget is less of a concern and you want the most refined lightweight 20” electric balance-style bike, STACYC is the halo option.

What age is a 20 inch electric bike for?

A 20 inch electric bike is usually best for older or taller children, often around 8–12+ depending on height, confidence and riding experience. Some confident younger riders may suit a 20” bike earlier, while others may be better staying on a 16” or 18” bike for longer.

Is a 20 inch electric bike too big for an 8 year old?

It depends on the rider. A tall, confident 8 year old may be ready for a 20” bike, but a smaller or less experienced rider may be better on a 16” or 18” model first.

Revvi 20 vs Amped A20 — which is better?

The Revvi 20 is a smooth, stable all-rounder for older or taller riders. The Amped A20 is a great confidence-building step-up bike with manageable power. The better choice depends on whether you want a smoother all-round option or a slightly more performance-focused Amped feel.

Amped A20 Pro vs Amped A20 Comp — what is the difference?

The Amped A20 Pro is the best performance-value option, with 800W power, hydraulic brakes and strong upgrade potential. The Amped A20 Comp is the premium off-road option, with a 1000W motor, upgraded suspension and a more serious chassis setup.

STACYC 20eDRIVE vs Amped A20 Comp — which should I choose?

The STACYC 20eDRIVE is the premium lightweight choice with a refined feel and strong motocross heritage. The Amped A20 Comp feels more aggressive and off-road focused. Choose STACYC for lightweight premium progression, or A20 Comp for stronger off-road performance.

What is the fastest 20 inch electric bike?

Among the bikes listed here, the Amped A20 Pro and Amped A20 Comp are the highest-performance options, both reaching up to around 28mph depending on rider, conditions and setup.

Which 20 inch electric bike has the best suspension?

The Amped A20 Comp is the strongest option for serious suspension, with double shoulder hydraulic adjustable front forks and a FASTACE rear air shock. The STACYC 20eDRIVE is also premium, with Manitou J-Unit Machete forks.
