1. I'm a FRED and don't wear spandex. 2. Doesn't wear out my prostate. 3. I have hopped curbs before, back when my bike was SS. Its really not that hard. 4. My tires being only 25c means that there is even less material hitting the pavement, meaning that there is an even lower 'coefficient of friction', making it a more efficient ride. And getting low on a BMX bike is actually bad for your back, because the rest of your body isn't in the correct position to be able to support your upper body being in an aero position like that. Theres a reason why people will do centuries and such on a road bike and not on a BMX bike. Same reason any length commute is going to be much easier, faster, more comfortable, and more efficient on a bike that is designed to go the distance.
