Amped A20 Comp vs A24 Comp: Which Electric Bike Should You Choose?

Quick answer: The Amped A20 Comp is the better choice for most riders who want a serious 20 inch full suspension electric bike with strong performance and manageable sizing.
The Amped A24 Comp is the bigger flagship option for taller, older and more experienced riders who need more size, more power and more room to grow.
If you are comparing the Amped A20 Comp vs Amped A24 Comp, the main difference is not just power. It is rider size, confidence, experience level and how much bike the rider actually needs underneath them.
Both bikes sit at the premium end of the Amped electric bike range, with full suspension, hydraulic disc brakes, off-road tyres and serious performance. The A20 Comp is the more manageable option for most young riders, while the A24 Comp is the larger flagship model for taller and more experienced riders.

Choose the Amped A20 Comp If You Want the Best All-Rounder

The Amped A20 Comp is the bike most families should look at first. It gives riders a proper premium electric bike feel without jumping straight into the largest and most powerful Amped model.
With 20 inch wheels, full suspension, hydraulic brakes and strong power, the A20 Comp is a serious upgrade from bikes such as the Amped A20 Pro, Revvi 18, Revvi 20 and other smaller electric balance bikes.
Amped A20 Comp is best if:
- The rider is around 130-160cm tall
- You want a premium 20 inch electric bike
- The rider is ready for more power but still needs manageable sizing
- You want a serious bike without going too large
- You want better value compared with the A24 Comp
For most young riders, the A20 Comp is the sweet spot. It is fast, capable and premium, but still easier to handle than the larger A24 Comp.

Choose the Amped A24 Comp If You Need the Biggest Amped Bike

The Amped A24 Comp is the flagship option in the Amped range. It is larger, more powerful and better suited to riders who are already too big for a 20 inch bike or who want the maximum long-term progression from the range.
The 24 inch wheels, 48V battery platform and 2000W peak output make it the better choice for taller teenagers and confident riders who need a bigger chassis underneath them.
Amped A24 Comp is best if:
- The rider is around 150-180cm tall
- The rider has outgrown smaller electric bikes
- You want the most powerful Amped model
- The rider is confident, experienced and sensible with power
- You want more room to grow long term
The A24 Comp is not the best choice for a nervous or small rider. It is a bigger, stronger bike and should be chosen when the rider is physically ready for it.
Not sure if you need the flagship model? Compare the sizing and riding experience carefully before sizing up from the A20 Comp to the A24 Comp.
Which Bike Is Faster?
The Amped A24 Comp is the faster and more powerful bike on paper. It has a larger 48V system, higher peak power and a higher top speed.
- Amped A20 Comp: up to around 28mph
- Amped A24 Comp: up to around 31mph
However, speed should not be the only reason to choose the A24 Comp. The bigger difference is the size and power delivery. A rider who fits the A20 Comp properly will often ride better, safer and with more confidence than they would on a bike that is too large.
Which Bike Is Better for Rider Size?
Rider fit is the most important part of this comparison.
The A20 Comp suits riders who need a proper full suspension electric bike but still want a manageable 20 inch platform. The A24 Comp is for riders who are already taller and need the extra wheel size, chassis room and power.
Simple sizing guide:
Choose A20 Comp: if the rider is roughly 130-160cm tall and wants the best all-round premium Amped bike.
Choose A24 Comp: if the rider is roughly 150-180cm tall, experienced and ready for a larger flagship model.
Which One Should You Buy?
For most riders, we would recommend the Amped A20 Comp. It offers the best balance of performance, size, price and confidence. It is still a very serious electric bike, but it is not as large or as intimidating as the A24 Comp.
The Amped A24 Comp is the right choice if the rider is already tall, experienced and likely to outgrow the A20 Comp quickly. It costs more, but gives you the largest and most powerful bike in the Amped range.
Garland Powersports Verdict
If the rider is between the two sizes, the safer option is usually the Amped A20 Comp. It is easier to manage and will suit more riders.
Choose the Amped A24 Comp when the rider is clearly tall enough, experienced enough and ready for the biggest Amped electric bike available.
