I'm guessing you are European? Bicycles in the US almost never have fenders except for old timey / retro style models. Fenders fell out of style in the 1980s and never really returned. People who do have them usually install them themselves as an upgrade.
Speaking as an American who owns a basic beach cruiser bicycle and
- puts less than 50 miles on it per year
- has zero desire nor space for a full electric bike
- would never use their bike in any kind of inclement weather
- would never use their bike for anything other than leisure
I think it might be aimed towards my demographic specifically?
Like this thing seems pretty neat, just strap it to my bike and go? Sign me up.
