Designed to replace internal combustion and electric two-wheelers, EX-BIKE
PROBLEM DEFINITION
Why the World Needs EX-BIKE
The current mobility system is structured to create pollution and consume energy at the same time.
🔴 Urban Air Pollution
Urban Air Pollution is a Daily Infrastructure Failure
  • Two-wheel-centric transportation structure
  • Daily health risks from fine dust and exhaust emissions
  • Limits in speed and cost of existing policies
The structure itself creates pollution through movement
🔴 Dependence on Internal Combustion Two-Wheelers
Combustion-Based Two-Wheelers Dominate the Streets
  • Hundreds of millions of internal combustion motorcycles in operation
  • Fuel consumption, emissions, and noise problems
  • Slow replacement speed and high dependence on infrastructure
No realistic alternative solution
🔴 Limits of Electric Mobility
Electric Mobility is Not a Complete Solution
  • Insufficient charging infrastructure
  • Battery costs and disposal issues
  • Power generation itself is still carbon-based
The energy consumption structure itself has not changed
🔴 The Limits of the 'Mobility = Consumption' Structure
Mobility is Designed to Consume, Not to Produce
  • The more you move, the more energy you consume
  • The more you move, the more the environment worsens
  • Mobility is a cost and does not create value
The limit of the mobility paradigm itself
The current mobility system is structured to create pollution and consume energy at the same time.
PROBLEM SUMMARY
THE TURNING POINT
If, in the moment of moving,
it could purify the air?
Mobility Until Now
  • Pollution is generated the more we move
  • Hundreds of millions of internal combustion two-wheelers dominate cities
  • It must consume energy in order to move
  • Mobility is a cost and does not create value
The question EX-BIKE asks
  • What if it could purify the air while moving?
  • What if it could generate its own power?
  • What if movement itself could become an asset?
EX-BIKE was designed to answer that question.
SOLUTION
Why EX-BIKE is the Solution
For the four problems above, EX-BIKE provides a structural answer.
Problems ①②
Mobility itself creates pollution
→ EX-BIKE cleans the air while it moves
It filters fine dust by drawing in outside air during riding and releases clean air. Movement becomes an act of purification, not pollution.
Problem ③
You have to consume energy to move
→ EX-BIKE creates its own power
It generates self-powered motion through a pneumatic compressor without external electricity, fuel, or charging. It changes the energy consumption structure itself.
Problem ④
Mobility is a cost and does not create value
→ EX-BIKE turns movement into an asset
Riding data, carbon reduction, and air purification performance are converted into carbon credit assets. Mobility itself produces economic value.
Not Electric. Not Fuel. A New Category of Mobility.

  • PM2.5 removal: about 300~500 tons/year
  • Reduced urban fine dust levels and lower health risks for citizens
🛵 Replacement of Internal Combustion Engines
  • When 100,000 units are replaced, annual CO₂ reduction: 150,000~200,000 tons
  • Direct elimination of NOx, SOx, and fine dust emissions
  • Reduced urban noise and mitigated heat island effects
⚙️ Infrastructure Transition
  • Energy: fuel → air
  • Infrastructure: gas stations·charging stations → unnecessary
  • Key point: "eliminating dependence on urban energy infrastructure"
Replacing 1% of motorbikes transforms an entire city.
