Tikit is different than the Travel bikes, Whole rear section, folds on the Tikit including the BB.
you can tension the chain directly and even make it as a Fixie, by pulling the dropout back.
Need to have bought the right rear section to get that feature.

The fold hinge is Behind the BB, like on the NWT/Pocket Llama,
so on those you always need the spring chain tensioner..
I got a Rohloff/pocket Llama this year , the German chain tensioner came on it.
