Most e-bikes come with 28-inch wheels. These offer stability and comfort, ideal for everyday use.
What size wheel in inches is best for an electric bike?
When choosing an electric bike, many people focus primarily on range or motor. But the size of the wheels and frame is just as important. The wrong size can reduce comfort and even lead to physical pain. In this article, we explain which wheel size in inches is right for which user, how to calculate frame size and what to look out for when buying an e-bike.

What does wheel size in inches mean?
Bicycle wheel size is expressed in inches (1 inch = 2.54 cm). This corresponds to the diameter of the wheel. The larger the size in inches, the bigger the bike.
Common bike sizes :
- 16 inches → often for young children
- 20 inch → children's bikes and compact models
- 24 inches → for teenagers or small adults
- 26 inches → formerly the standard size, now common on sports bikes and small e-bikes
- 28 inches → the most popular size for adult electric bikes
- 29 inches → especially for MTB
How do you determine the right wheel size for an electric bike?
The right size depends on the user's height, age and intended use.
Children
- 16 inches → for children aged 4 to 6 (height ±105-115 cm)
- 20 inches → for children aged 6 to 8 (±115-125 cm)
- 24 inches → for children aged 8 to 10 or ±125-145 cm
Teenagers and adults
- 26 inches → from 11-12 years or a height of ±145-160 cm
- 28 inches → ideal for adults from ±160 cm
- 29" → for sport cyclists and mountain bikers looking for more grip and speed
The difference between wheel size and frame size
Wheel size is sometimes confused with frame size, but they are two different things:
- Wheel size (inches): wheel diameter
- Frame size (cm): frame height, adapted to body size and inseam length
A 28-inch bike, for example, can come in different frame sizes (50, 54 or 57 cm). That's why it's important to calculate frame size in addition to choosing the right wheel size.
What wheel size should I choose for my e-bike?
- City bikes and electric transport bikes: generally 28 inches
- Small e-bikes or folding bicycles: 20 or 24 inches, practical in town and easy to transport
- MTB : often 27.5 or 29 inches for better grip and control
- Compact electric bikes for short distances: 26 inches
Tips for choosing the right size
- Measure your height and inseam length to determine the right frame size.
- Think in terms of use: short urban journeys or long strolls
- Always do a test run: you'll know right away if the wheel size is right for you.
Conclusion
For most adults, a 28-inch electric bike is the best choice. This size offers the ideal balance between comfort, stability and efficiency. For children, small adults or specific uses (folding bikes or MTB), other sizes are more suitable.
By taking into account both wheel size and frame size, you'll always find an e-bike perfectly suited to your body shape and needs.
