Shop Kids Electric Bikes by Rider Height
Choosing the right electric bike by rider height is often more accurate than choosing by age alone. Children grow at different rates, so height, confidence and previous riding experience should all be considered before choosing a bike.
This guide helps you shop kids electric bikes by height, from small starter bikes for younger riders through to larger 18”, 20” and performance-focused electric bikes for taller, more confident riders.
Quick Answer
Riders under 105cm usually need small 12” starter bikes. Riders between 105cm and 120cm usually suit 16” starter and progression bikes. Riders between 120cm and 135cm often move into larger 18” and 20” youth electric bikes. Riders over 135cm may suit 20” bikes or more performance-focused models depending on confidence.

Shop Electric Bikes For 135cm+ RidersShould You Choose By Height Or Age?
Age is useful, but height is often more accurate. Two children can be the same age but need completely different bikes because of height, strength and confidence.
Height Helps With
- Choosing the correct frame size
- Making sure the rider can reach the ground
- Avoiding bikes that feel too cramped
- Making the bike easier to control
Confidence Helps With
- Deciding how much power is suitable
- Choosing between starter and performance models
- Knowing whether to size up
- Matching the bike to the rider’s ability
Should You Size Up?
It can be tempting to buy the biggest bike so the rider can “grow into it”, but this is not always the best choice. A bike that is too tall, too heavy or too powerful can make a rider nervous and slow down their progression.
Do Size Up If...
- The rider is already confident
- They are physically strong enough
- They can touch the ground safely
- They have previous bike experience
- They are outgrowing their current bike quickly
Do Not Size Up If...
- The rider is nervous
- The bike feels too heavy
- They struggle to stop or turn
- They cannot comfortably reach the ground
- They have no previous riding experience
My Honest Verdict
For the youngest riders: start with the Revvi 12, Amped A10 or STACYC 12eDRIVE.
For riders between 105cm and 120cm: look at the Revvi 16, Amped A16 or Revvi 16 Plus.
For riders between 120cm and 135cm: the Revvi 18, Amped A20 and Amped A20 Pro are usually the strongest options.
For riders over 135cm: the Amped A20 Pro, Revvi 20 and Amped Comp models are where we would usually start.
