I can not stress enough to my friends how useful the trike is. Early game it makes a great pack animal. Late game in groups of three or four it can be used as a decent battle mount. Taming a trike early on can be a great way to start a large base and keep you well fed with berries.
A triceratops is a very special dinosaur in this game. It is easy enough to tame at a low level, yet powerful enough to take on raptors that could kill you easily. It can collect enough berries that you would never go hungry again, and still have some berries leftover to help tame more trikes. They are very slow but it can make up for it if you increase the weight, attack, and stamina stats. It is an extremely good pack animal because it can carry a lot, but still defend itself, especially if it is in a large group. Overall, the triceratops is one of my favorite and most versatile dinosaurs.
To tame one of those early game you just need to get yourself a slingshot (You can get the engram at Level 5), a low Level Trike (Level 1 - 30) and to be safe around 40 Stones. Then find some Trees and attack the Trike with your Slingshot then use a Hit and Run Technique. It should be much easier because the Trike gets stuck in the Trees and has to get around them. Which gives you enough time to shot him some times with your Slingshot. Once he is unconcious you just have to gather Berries. Use Mejoberries for a higher level after taming. Keep an eye on the Trike's Torpor(You find it in the bottom right hand corner in its Inventory). Once it drops on 0 your Trike will wake up and you have to knock it out again. To raise its Torpor you need to put Narcoberries in its Inventory, click on them and then click on the Remote use item Button (Each Narcoberry adds 8 Torpor). In the Dododex App you can Look how many Slingshot-Shots, Narcoberries and Mejoberries your Trike needs. Good Luck!
The best way to utilize the trike when tamed or untamed when tamed it can gather loads of berries for you or when it's untamed you can use it as a shield for instance like a carno is running after you and there's a trike try to run for the trike to get the carno to fight the trike so you can escape unharmed
I have found that the Triceratops/Trike prefers the tintoberries, my strategy for taming lvl 10< Trikes on a new charachter i usually grab around 40-100 tintoberries and 3 or 5 narcotics/10-25 narcoberries and i use the starve method for around 4 minutes before using a narcotic and putting the berries in!
The trikes are amazing for gathering a huge amount of narcoberries, i ride my Trike to the hills and keep hitting the bushes and then I access the Trikes inventory and grab what i want to keep and then press drop all items for the Trike.
I strongly recommend everyone to tame this creature and pump stamina weight and a little bit of health and speed as this will turn it into the perfect all around useful mount it's knock back effect , his ability to farm berries and if his weight is high allows him to carry ultimate amounts of resources and survive most predators
