Wheel diameter
Bikes with large wheels are faster, but also more difficult to control. For city bikes, the common wheel diameters are 20", 26" and 28".
- 20” wheels are more compact and better manoeuvrable, but slower.
- 28” wheels let you ride faster, but they take up more space and their manoeuvrability is worse.
When choosing, consider your riding style and preferences.
Motor mounting position
E-bikes have several types of motor mounting configurations and each of them affects riding performance and handling differently.
- E-bikes with a mid-drive system are easier to control and the ride is smoother.
- E-bikes with a hub drive (front/rear) are not as well-balanced as mid-drive bikes.
Frame material
Frame material affects the bike weight and characteristics.
- Aluminium is the most common frame material due to its light weight and low cost.
- Steel is quite heavy and susceptible to corrosion. On the other hand, the bike is steadier when riding on uneven surface.
- Carbon or carbon composite is five times lighter and six times stronger than steel. It has high durability and great shock-absorbent properties.
