This is my low level way to tame a trike:

1) get a slingshot, the resources to repair it, mejoberries, narcoberries, and a bunch of rocks (I prefer at least 200)

2) go to a beach with one and find a large rock he can’t climb (make sure it is very steep)

3) shoot him anywhere but the head (he won’t get knocked out if you shoot him in the head) while on the rock

4) when he is knocked out, give him the mejoberries and narco berries and let him eat (do not force feed him unless he is running out of torpor then you can feed him the narcoberries)

Boom you got a trike
