Even outside the racing bicycle market lightweight design is getting more and more popular. Recently one of our customers CarboFibretec commissioned a study on an electrically powered cargo bike. The bottom bracket is one of the key components of the concept and needs withstand the heavy loads required to support the electric motors.
Within this project the geometrical freedoms of the Carbon-SMC technique were perfect to use. In combination with transitions of the wall thickness and reinforcement ribs the design could be tailored for the required load conditions. In addition, integrated fits, inserts and positioning aids allow for the perfect integration of the electric drive components and the pedals.
