There is no evidence in the cited scientific work of a complete nanoscopic bicycle or a lock made for one. The phrase works better as a question about molecular machines: researchers have manipulated a molecule with two wheels, and scientists use bicycles to explain how tiny machines might turn directed motion into useful work. Neither result is a report of a molecular bicycle lock.
What does “a lock for a nanoscopic bicycle” refer to?
The phrase does not identify a verified device or established scientific object in the sources cited here. The available work offers two related but distinct ideas: an experiment that induced motion in a single molecule with two wheels, and a bicycle analogy used to explain the requirements for a molecular machine. A separate review compares a conventional bicycle chain lock with molecular interlocking. These are scientific results and explanatory comparisons—not evidence that a complete nanoscopic bicycle, or its lock, has been built.

What did researchers actually make move?
In a 2007 paper, L. Grill and coauthors reported inducing the rolling of a single molecule equipped with two wheels, each 0.8 nm in diameter, using the tip of a scanning tunnelling microscope (STM). The reported work concerns controlled molecular-scale motion and manipulation, observed through STM signals; it does not describe a complete bicycle or a locking mechanism. Read the paper in Nature Nanotechnology.
Why compare a molecular machine with a bicycle?
Itamar Willner’s 2020 ACS Central Science Outlook uses a bicycle to explain the difference between movement and machine-like work. A bicycle does not become a useful machine merely because its wheels turn: the analogy calls for an energy source, directionality, and a load that receives the work. At molecular scale, this helps frame what a machine would need to do. It is a teaching analogy, not experimental evidence of a molecular bicycle.

What does a bicycle lock have to do with molecular interlocking?
A 2014 Royal Society of Chemistry review, “Functional interlocked systems,” uses a conventional bicycle chain lock as a conceptual comparison for mechanically interlocked molecular architectures. The analogy concerns how a ring around a stoppered bar can regulate access or position. It does not describe a nanoscale product that secures a bicycle. Read the RSC review.
Could such a lock be built—or bought?
The sources cited here establish molecular motion experiments and analogies, not a practical nanoscopic bicycle lock or a complete molecular bicycle. They do not provide a design, performance specifications, or a product to purchase. A standard bicycle lock would address an ordinary bicycle, not the nanoscopic subject implied by the phrase.
