Gear Guide

Ride harder. Stay connected. Keep your phone where you need it on the trail.

Mountain bikers need their phone for navigation, trail maps, and capturing the descent. The problem is every carrying option either buries it in a pack or risks it on a handlebar mount. The KOALA 2.0 by HANGTIME was built to solve that.

Why It Matters

What mountain bikers actually need from a phone solution

Secure through every hit Pockets eject phones on drops. Jersey pockets bounce on rough terrain. The KOALA's Super-Grip pad and bungee tether keep your phone locked to your chest through rock gardens, berms, and technical descents.
One-handed access on the trail Pull up a trail map, check your GPS, or snap a photo without stopping. No digging through a jersey pocket, no stopping to unzip a pack. Your phone is right there when you need it.
Works with any kit Fits over a jersey, a base layer, or a lightweight shell. No case required. Compatible with virtually all smartphones. Doesn't interfere with your hydration pack straps or chest strap.

How It Works

Built for the trail. Not the road.

The KOALA 2.0 uses a Super-Grip silicone pad and bungee tether system to keep your phone locked against your chest. It works with virtually any smartphone — no case required — and fits over a jersey, a base layer, or a lightweight shell.

One-handed access means you can pull up a trail map, check your GPS, or snap a photo without stopping. It's the difference between capturing the descent and missing it — or worse, getting lost on a remote trail because your phone was buried in a pack.

Where It Works

Flow trails. Enduro stages. Bikepacking. All of it.

Mountain bikers use it to navigate remote trails, document descents, and stay connected in the backcountry. Enduro riders rely on it for stage navigation and emergency communication on multi-day events where leaving your phone at the trailhead isn't an option.

It's also the go-to for gravel riders, bikepacking, and anyone who wants their phone accessible without the bounce. 2,040+ reviews from riders, climbers, and skiers who've put it through real conditions.
