Your question is very non specific which makes it hard for people to respond. Alot more information is needed. First, What Trike? Do you wnat to mount it behind the seat? or to the front Wheel? Are you going to purchase the Complete Titan Rack Mount kit or just the Titan Motor? Photos are always a big help? There is a member Large Filipino who has mounted a Titan Kit to the front of his Trike and seems to be quite happy with it. I can't say that I have seen or heard of one mounted to the rear? There was a member who mounted the Titan motor in the rear of a custom made/modified cargo bicycle.
