I do not like the single arm fork and the special front hub required to mount the wheel on such forks (the same issue exists for the Helix: its very difficult to find a front hub that fits on the single sided fork of the Helix).

If a failure happens of the front hub (due to the bearing or the hub itself, for instance due to water/moisture) there is a major risk to be unable to find a new hub that fits on this specific fork.

The lack of front carrier is also a major drawback. Like on the Brompton, the rear rack s not good to carry things and doesn't allow to use side pannier (too low, too close to the pedals and heels when pedaling).
