Development and Production

Spring wooden bike frames are result of thoughtful development. Geometry is developed by modern methods such as numerical simulations and advanced 3D modeling. Special focus was given to testing, to achieve best performance and riding experience. As result the bikes are lightweight (between 1,7 and 2,1 kg) and fun to ride.

During production both accuracy and proper material selection are of great importance to us. Raw material is carefully chosen and machined to perfectly matching parts which are then bonded together with special glue mixture.

After that the surface is grinded to perfect smoothness and protected from any weather conditions with transparent coating.

About us

Wooden bicycles Spring are the result of great technical knowledge, designed with computer software for simulations, to get the optimal weight-to-stiffness (performance) ratio of the bicycle. They are made out of birch wood, as this allows for the best weight-to-stiffness ratio. The frame weighs less than 2 kg, depending on the size of the frame (available in sizes SM, or L, or custom sizes). All Spring products are made with Slovenian wood, which makes them environmentally friendly, and means we can take advantage of the natural potential offered by our local environment.

Wood Properties

Wood indeed has some superior properties that are reflected in Spring bike frames.

DURABILITY

Durability of wood is truly remarkable. Unlike aluminum, wood will not break after thousands of kilometers on road, but will remain in sound condition after many years.

DAMPING

Wood’s vibration absorption capability is just remarkable. This makes riding Spring wooden bicycles smooth and comfortable.

STIFFNESS

Properly treated wood is stiff and hard enough to allow for good responsiveness and effective transmission of the power from pedals to the rear wheel.

LIGHTWEIGHT

Based on material studies, birch wood was selected due to the excellent weight-to-stiffness ratio. Consequently, the weight of a Spring wooden frame is, depending on the size of the frame, only between 1.7 and 2.1 kg.

BEAUTY

The color of the wood is as unique as our fingerprints. This makes every wooden bicycle frame beautiful and one of a kind.

Customized features

  • Unique bicycle sizing 
  • Frame tattoo
  • Integrated cadence & speed sensor
  • Other wood types
  • Selection of colors
  • Disc caliper mount
