Sport mode is one of the four classic ride modes on Bosch motors. The original list was
- ECO with 60% support
- TOUR with 140% support
- SPORT with 240% support
- TURBO with 340% support
Those support numbers are correct for the Performance CX motors Gen4 and Gen4 Smart System. Other models did have slightly lower numbers.
Over time Bosch added multiple new ride modes in order to support different rider needs.
- eMTB, progressive mode with support from 140% to 340% depending on rider input power, developed for MTB enthusiast, gives more control, adds extended boost function
- eMTB for short cranks (165mm and shorter), progressive mode with support from 140% to 340% depending on rider input power, less power needed to reach higher support
- TOUR+, progressive mode with support from 60% to 340% depending on rider input power, developed for touring, needs more rider input than eMTB standard to reach higher support levels, supposed to be more economic
- AUTO, adaptive mode with support from 60% to 340% depending on riding resistance (head wind, climbs), developed for the city/trekking rider, holds moving average speed of the last few seconds without the rider needing to raise own effort, quickly moves up to the higher support levels
So now, with the newest update and only for the smart system motors, there are a total of eight different modes. All need to be installed on the motor either by the bike manufacturer at delivery or later by an LBS. Then these modes will show up in the Flow App and you can select any combination of four from the list. In some cases the manufacturer can restrict the available modes.
For some special motors there are even more modes.
- Cargo motors have CARGO mode with 400% support and more controlled start behavior even with full load.
- Race motors have RACE mode, a more aggressive eMTB mode with up to 400% support and longer extended boost.
- The SX motors have a SPRINT mode with up to 280% support depending on cadence (higher than 100 needed), developed for gravel bikes and city commuters.
