ICE developped the Compact Twist Fold System, it's standard on all models.

Fold an ICE in 3 steps
- remove the seat  (2 easy knobs, 1 quick release)
- turn the steering handle (1 quick release)
- fold the trike (1 quickrelease with safety lock)

If needed slide the front stem shorter, you have now a packet of about 0,80m x 0.80m x 0.50m.
If you remove the front wheels, the package is still smaller.
