I have 2 of them, a pair that spawned near my base.

My taming tip: if there are rocks nearby that are taller than the Trike and you can jump up on; then shoot the Trike a few times with a Tranq arrow to get it mad and then run to the rock and climb it. Make sure you have plenty of Tranq arrows and then shoot away. Mejo berries are useful so if you have a bunch of those then that helps. If not then just put a bunch of random berries and keep topping them off until the Trike is tamed.
