THE TASK

How do you foster children's motor skills and coordination through play? The brief: a product that picks up their urge to move and sparks joy in locomotion through muscle power and dexterity.

APPROACH

A decentrally spoked rear wheel generates propulsion through up-and-down motion alone, with no further parts. A frame of laminated wood is the visual highlight, ecological and locally producible. The low-complexity build keeps the vehicle light, robust and low-maintenance.

CHALLENGES

  • → Making the wooden frame light, elastic and still stable
  • → Reproducible fabrication of a free-form wooden frame with simple means
  • → Reducing parts and complexity
  • → Making a durable offset rear wheel in-house

RESULT

The unusual drive method is fun and first demands learning the necessary coordination: balance, timing, weight shift. The frame with integrated footboard is light, elastic and beautiful to look at.

TECHNICAL EXECUTION

  • → 1:10 paper model to check proportion and feasibility
  • → Layers of 7 mm waterproof-laminated gaboon plywood, hollowed for weight
  • → Steering tube rolled and laminated from 0.6 mm sheet steel, light and stable
  • → Spoke lengths simulated in Adobe Illustrator, cut and Z-bent to size
  • → Form lamination with a custom mould

WHAT STANDS OUT

The decentral hub position, an almost forgotten drive technique, reinterpreted here. The wooden frame could be produced to a high quality with simple means.
