According to the search results, a 250 watt motor is generally enough for daily use and providing a little extra boost, but may not be enough for hilly or difficult terrain, steep hills, towing, and speed racing (source: [eBike Savvy](https://ebikesavvy.com/is-250-watts-enough-for-an-e-bike/), [THEBICYCLEGEEK](https://www.thebicyclegeek.com/is-250-watts-enough-for-ebike/), [sixthreezero](https://www.sixthreezero.com/blogs/bike-advice/is-250-watts-enough-for-your-ebike)). It is also noted that e-bikes typically use motors ranging from 250W to 750W (source: [Electric Bike Report](https://electricbikereport.com/is-250-watt-motor-enough/)).
A 250 watt of power is enough for an electric bike. A 250 watt of power electric bike can only go on a flat land without any pedaling.
A heavier rider can go on a ride on flat land and struggle climbing hills with a 250-watt power electric bike on full throttle.
Attempting to go on long hills with a 250-watt power electric bike as a heavy person would be risking damage to the motor. The bike is only efficient on flat terrains and small hills.
