As both a skater and a biker, I'll try and explain the reason for the rift:

• Bikes are heavy and hard (harder than plywood/flesh) and cause far more damage to the structure than a 1000 skateboards could. This is a fact, no point in disputing it.
• Bikes pick different lines to skate/scoot. They roll faster, have a longer wheelbase and are less agile, leading to lines which are more gradual/smoother. These lines are not the same as skate/scoot, and lead to collisions as inexperienced people can't predict them.

However, at our local spots the bikers have been embraced because when it comes to re-plying the ramps every spring (after the winter freeze has ruined the top layer) and mid summer when getting a bit worn, the bmx boys are the first there with their tool belts and fully charged cordless drills and a few sheets of ply. Or cinderblocks, concrete mixers and steel pipe. Or in this case (Queenstown, where I live, where the Gorge Road Jump Park is), turning up with shovels and utes full of dirt. There was VERY little financial support for this park from anyone, just the boys getting together and digging.

You want to be that guy, who people want around because he fixes more than he breaks. A lot of people aren't, and your prefered vehicle is a lot higher risk of damaging than what you may be worth.
