Door N. 3 .. Bike Friday Tikit is more customizable to your component choices
+ is made in more than one size , the hyper-fold feature is fast to operate
you roll the folded bike by its front wheel,
and because the seat hinges to fold rather than telescope into the frame

like you must with both Brompton and Dahon, so with the Tikit,
your saddle height remains un changed with every fold.

Brompton rear wheel folds straight under , the other 2 the wheel folds along side..
Brommy folds the front wheel, back then it covers the crank & some greasy drivetrain.
