The main difference between an e-bike and a fatbike lies in their design, intended use and specific features. Here is a brief explanation of the difference.
Tire design: An e-bike usually has standard tires similar to those of traditional bicycles. These tires are narrower and designed for general use on paved roads and bike paths. A fatbike is distinguished by its wide tires, usually between 4 and 5 inches wide. These extra-wide tires are specially designed to provide stability and grip on rough, unpaved terrain, such as sand, snow, mud and rocky trails.
Intended use: E-bikes are designed for general use and are often used for commuting, recreational cycling on paved roads and bike paths, and covering longer distances with pedal assistance. Fatbikes are specifically designed for adventure cycling and off-road riding. They thrive on challenging terrain and are ideal for adventurers who enjoy exploring off-road trails, such as beaches, snow-covered paths, and unpaved trails. In the Netherlands, you also see fatbikes a lot more in cities and towns
Tire Characteristics: The tires of an e-bike are designed for efficiency on paved roads, so they are less wide and have less rolling resistance. A fatbike's wide tires offer significantly more stability and grip on uneven, soft or slippery surfaces. They float, so to speak, on top of soft terrain, making them well suited to sandy beaches or snowy roads.
Electric support: Both e-bikes and fatbikes can have electric pedal assistance. The difference lies in the intended use of this support. E-bikes with narrow tires are more focused on facilitating everyday cycling on paved roads, while e-fatbikes combine electric assistance with off-road capabilities for adventure riding.
