Why do so many e-bikes have fat tires?

Discover the intriguing rationale behind the prevalence of fat tires on most electric bikes. The surge of electric bikes, or e-bikes, has been remarkable in recent years. These bicycles are equipped with a compact electric motor that assists the rider while pedaling, making long journeys or steep inclines more manageable. However, one distinguishing feature that has captured widespread attention is the prevalence of fat tires on electric bikes.
Initially, the oversized tires may appear to be merely a stylistic preference or a measure to enhance traction for off-road adventures. Yet, there is a deeper purpose behind their dominance in the e-bike realm.
The primary motivation for utilizing fat tires on electric bikes is to support the increased weight and power of the motor and battery. Conventional bicycles are designed to bear the weight of a rider and perhaps some equipment, whereas e-bikes can be substantially heavier due to additional components. The fat tires offer a broader contact area and air volume within the tire, leading to enhanced stability and maneuverability when carrying heavier loads.
Another asset of fat tires on electric bikes is their adaptability to diverse terrains. Featuring a wider tread and lower tire pressure, these tires can adeptly navigate rough or uneven surfaces like gravel, sand, or snow. This versatility attracts urban commuters and outdoor enthusiasts seeking a bike capable of conquering any road condition.
Moreover, fat tires provide a cushioned ride by absorbing more impact from bumps and obstacles on the path. This characteristic proves especially advantageous for individuals with joint or back issues, as it minimizes the strain on their body during rides. Consequently, it ensures a more pleasant and comfortable biking experience, making extended journeys or daily travels less arduous.
Enhanced traction is another notable attribute of electric bikes equipped with fat tires. The expanded tire surface area maximizes ground contact, resulting in superior grip and steadiness. This feature proves invaluable when navigating wet or slippery surfaces, effectively reducing the likelihood of accidents.

its a motorbike, thats why.

Probably because e-bikes and most of their riders are heavy and normal tires aren't rated for so much weight.
