Last year they did set the world speed cycling record of 83,13 mph (133,78 km/h) with the composites-intensive VeloX 3 recumbent bike.
The Human Power team at Delft University of Technology and the VU University of Amsterdam aimed to break that record with their next bike VeloX 4. The result ended in a win for men’s World Human Powered Speed Challenge 2014 in Battle Mountains, with only 1,53 km/h from a new world record so VeloX 5 are now being developed ready to challenge the impossible.
VeloX 4 shell are built in sustainable Styrene-free Daron® Resins from DSM in combination with TeXtreme® carbon fiber.
Thomas Wegman marketing manager of DSM Composite Resins says at DSM webpage: “The main focus of the VeloX IV designers was on road-holding ability, air resistance and crash protection. We helped them translate this into the use of stiffer materials, so that deformation at high speed can be prevented and the optimal aerodynamic shape is retained even in at high air pressures.”
Wegman continues that the students’ project taught DSM some new things about composites: “Traditionally, DSM’s resins were used in particular in glass fiber reinforced composite parts. “Projects like the VeloX have taught us a lot about how our materials work with carbon fibers.”
