You bought a bike that's meant to go through gnarly technical terrain and do it as fast as possible. Bar-ends are a hazard. If you're actually planning on mountain biking with it you'll get laughed at because no serious biker uses them. I realize what other people think about you isn't that important but seriously they provide zero benefit for actual mountain biking.

I would recommend you just get a commuter or road bike for paths and roads. It'll faster and more enjoyable than riding something that was built explicitly for off-road use. The weight difference alone makes it worth it.
