You don't get multi speed with a simple single speed transfer case unless you get jackshaft over or use a reverse rotation pocketbike transfer case.
Both of what you have are single speed transfer cases. You can choose what gear you are stuck in, pretend you have a broken transmission that can only use 1 gear: do you want to be able to climb hills in 1st gear but be limited to a low speed with high rpms? Stuck in 3rd, kinda slow on takeoff, decent speeds and will slow down on hills but maybe take them but only if you pedal. Or stuck in 5th (your gear ratio), destroy your clutch some every time you accelerate from a stop, very slow acceleration, high top speed and no ability to take hills without moving into the clutch destroying rpm range.
Your choice.
