An electric bike that disappears under a desk.

Spark

Mara measured Berlin apartments and train vestibules before drawing a hinge.

The product is the fold, not the motor.

Friction

Most folding e-bikes still look like machinery when folded.
Fold is for apartments where the bike has to become furniture.

Bet

An electric bike that disappears under a desk.

Build

A single-motion hinge, a hidden 250W drive, and a 40km battery in the frame.

The latch is mechanical; nothing to charge before you store it.
