- the input device enables virtual shifting beyond the available physical transmission ratios, e.g. to expand an installed physical 9-speed cassette to a virtual 11- or 12-speed cassette, or a single speed to a multiple speed.
- the computer or controller is preferably configured to receive input, e.g. via a keypad, computer, or smartphone, from a user to enter and/or amend the virtual gears.
- the invention further relates to a computer program comprising instructions to cause the system as described above to execute one or more of the steps of the method as described above, as well as to a computer-readable medium having the computer program stored thereon.
- a stationary exercise bike comprising: a support structure; a pair of pedals rotatably mounted to the support structure; a force-generating device operably connected to the pedals and generating a variable resistance force to the pedals; a force sensor configured to measure a force applied to the pedals by a user, wherein the force sensor measures a relative displacement of first and second points on the stationary bike that are interconnected by a drive structure defining a stiffness whereby a force can be determined based on the relative displacement and the stiffness; and a controller operably connected to the force-generating device and the force sensor, wherein the controller varies the resistance force generated by the force-generating device to simulate inertial effects based, at least in part, on a force measured by the force sensor.
- FIG 1 shows a smart trainer 1, comprising a frame 2 in a housing 3.
- a force generator in this example an electric motor, is fixedly mounted to the frame and accommodated inside the housing.
- a cassette 4 of sprockets is mounted on the axle of the force generator or coupled to the axle of the force generator via a transmission, such as a belt drive.

- F ped F Res . R wheel R ped .
- Real Front Real Rear Real Rear Rear Front .
- Virt Front Virt Rear Physical Gearing ⁇ Virtual Impact which yields front and rear mapping:
- F ped F Res . R wheel R ped .
- Operation is illustrated in Figure 3 and involves measuring force and angular speed of the axle, determining the number of physical gear teeth in the front (e.g. 53, see Figure 2 )) and in the rear (e.g. 21), for example from variations in the rotational speeds over a period of time, update the physical gearing map, find the front ring index (e.g. index 2), find the rear sprocket index (e.g. index 9), lookup virtual front ring from index (index 2 corresponds to 50 virtual teeth, in Figure 2 ), lookup virtual rear sprocket from index (index 9 corresponds to 30 virtual teeth, in Figure 2 ), update force and angular speed, and adjust the force provided by the generator.

- find the rear sprocket index e.g. index 9
- lookup virtual front ring from index index 2 corresponds to 50 virtual teeth, in Figure 2
- lookup virtual rear sprocket from index index 9 corresponds to 30 virtual teeth, in Figure 2
- the physical gearing ratio that is selected by the rider is determined, preferably automatically, and subsequently used to map the physical gears onto virtual gears that may or may not be the same as the physical gears on the bicycle trainer.
- the rider experiences the resistance as if he was riding on the virtual gears.
- the effect of the physical gearing can be eliminated from the resistance.
