Analysis and Design of a Bionic Fitness Cycle
3.5 Development and Test
At present, the first prototype (Figure 3.16) has been developed and has
been used to determine the scheme and to design the mechanical structure.
Through several debugs and the corresponding experiments on the prototype, the feasibility of the Bio-Cycle has been proven. Each adjustment range
according to the ergonomic design was in line with the requirements of comfort. As for the resistance system, the adjustment range can be set by programming and initializing the steering engine, and the test has shown that
its resistance torque ranges from about 10 to 25 Nm, which is sufficient for
different people’s needs. We also invited a couple of people to test the resistance control in different exercise motions, as shown in Figure 3.17.
Most test persons felt the training of the lumbar muscles to be relatively
strong at a larger tilt angle of the supporting bar, which was set while testing the mode of bionic riding. In comparison, the training of the limb muscles was felt to be stronger at a smaller tilt angle of the supporting bar. This
shows that that the changes in the depression angle have a great influence on
the effect of the exercises.
3.6 Conclusions
In this study, we analyzed the principle of a bionic fitness cycle and its
new characteristics. A four-drive transmission system and a compound
resistance system have been developed. We planned the overall size and
designed the structure to meet the requirement of ergonomics in order to
render the riding more comfortable for different groups of people. We also
developed an interactive interface so that the user could obtain the exercise
information in real-time and control it accurately. As a new riding motion
was created, we analyzed the characteristics of its resistance system and
designed a compound resistance system to adequately fulfill the requirements of comfort and safety. This new fitness cycle puts forward a completely new exercise concept and brings the users a more enjoyable riding
experience. We hope it will provide new impulses to the fitness industry
and to bicycle sports.
