Lightweight wooden frame – 1.95 kg (made out of carefully selected and precisely dried local birch hardwood to minimize our carbon footprint).
Shock and vibration-absorbing frame (wood in combination with a smart design gives the frame ultimate shock and vibration-absorbing capabilities).
Monocoque frame design (monocoque frame design with less than 5 mm wall thickness and produced with highly accurate CNC machining delivers excellent weight-to-stiffness (performance) ratio).
Hollow chainstay (to reduce the weight even further without compromising the performance, chainstays are made hollow. This feature also allows us to route the rear derailleur cable internally.).
Integrated seat clamp (seat clamp is hidden under the wooden monocoque structure to keep the aerodynamic design and looks uncompromised).
Extremely strong epoxy adhesive (in-house developed adhesive gives just the right flexibility to the bonds while keeping them super strong throughout the lifetime of the frame).
UV protection (carefully chosen 3-layer transparent coating protects our frames against all weather and road conditions).
The geometry of the bicycle can be adapted to a customer’s specific needs.
Work, classes, and new adventures along your way with the Spring city bicycle. Ultra-lightweight wooden frame and optimal positioning for a comfortable and upright smooth ride adapt to the city surfaces and obstacles.
It is possible to choose non-standard equipment of higher or lower quality. The price depends on the choice.
