E-Bike mid-motors

Description

Using the specially developed test bench for mid-mounted e-bike motors, it is possible to test the operational stability and the function of the control system at an early stage of development. In endurance tests, the mid-motor can be subjected to load collectives consisting of time-weighted speeds and torques, thus enabling the behavior of the motor to be observed under long-term load. The test bench is able to emulate a driver cadence of up to 150 rpm and a maximum crank torque of 300 Nm. All performance data of the mid-engine are measured.

Cargo bikes are one of the fastest-growing model groups on the e-bike market. The focus in the development of the drive is increasingly on combining the support motor, an automatic gearbox and a regenerative brake in one unit. By means of a V-belt CVT or combinations of planetary gear sets, new economical overall solutions are emerging that fulfill the aforementioned aspects in the form of a mid-motor. The concepts investigated provide for an adjustment range of over 400 %.

Revolutionary Advantages: 3D-Printed Cycling Jerseys Optimized for MTB and Road Racing

3D-printed cycling jerseys promise a new era of sportswear tailored precisely to the specific needs of mountain bikers and road cyclists. Thanks to precise manufacturing, these jerseys offer not only a perfect fit but also elevate function and protection to an entirely new level.

For Mountain Bikers: Adaptive Protection

A mountain biking jersey that protects without getting in the way – that’s the vision of 3D printing. Flexible protective structures made from hexagonal elements can be integrated directly into the fabric. These honeycomb-like designs are highly efficient at absorbing impact energy (ideal for trail crashes) while offering excellent freedom of movement and breathability. Strategically placed at the shoulders, elbows, and back, they provide targeted protection where it matters most, all while being lighter and more comfortable than conventional protectors. The result is a second skin that protects and breathes with you.

For Road Cyclists: Aerodynamics That Save Seconds

In road racing, every millisecond counts. 3D-printed jerseys can make all the difference by minimizing air resistance. Fine surface textures or strategically placed guiding elements and fins can optimize airflow around the body. Much like the dimples on a golf ball, microscopic structures in the fabric influence the air in such a way that it clings longer to the body, reducing turbulence. The result is enhanced aerodynamics that help you reach the finish line faster. These invisible features are seamlessly integrated into the jersey, ensuring a perfect fit and helping you maximize performance with every pedal stroke.
