Which Electric Bike Is Best For A Rider Between 120cm And 135cm?
This is one of the most important height ranges to get right. A rider between 120cm and 135cm tall is often too big for a smaller 16” bike, but not always ready for a full-size youth performance bike.
If the rider is steady or still building confidence, the Revvi 18 or Amped A20 are the safest places to start. They give more size and stability without making the jump feel too intimidating.
If most confident riders in this height range asked which bike we would recommend, the Amped A20 Pro would usually be the answer. It offers the best balance of size, power, braking performance, suspension and room to grow.
The main thing is not just buying the biggest bike possible. The right bike should help the rider progress, not make them nervous.

- Closer to 120cm: Revvi 18 or Amped A20
- Closer to 125cm-130cm: Amped A20 or Amped A20 Pro
- Closer to 135cm: Amped A20 Pro, STACYC 20eDRIVE or Amped A18 Comp
Why Height Matters More Than Age
Age is helpful, but height is usually the better starting point when choosing a kids electric bike.
Two children of the same age can be very different sizes, and confidence level makes a big difference too. A correctly sized bike helps the rider reach the ground, stay balanced and build confidence much quicker.
My Honest Verdict
For newer riders: choose the Revvi 18.
For best value: choose the Amped A20.
For most confident riders: choose the Amped A20 Pro.
For premium lightweight feel: choose the STACYC 20eDRIVE Brushless.
For more experienced off-road riders: look at the Amped A18 Comp.
