What are the best methods for adjusting the throttle response time on an ebike for optimal hill climbing performance, and are there any specific settings or techniques that can be used to improve efficiency and reduce battery drain? How do different throttle response settings affect the ebikes overall performance and handling on varying inclines, and what are the trade-offs between instant torque and gradual acceleration? Are there any specific ebike models or systems that are better suited for hill climbing, and how do their throttle response settings compare to others? What role does cadence play in throttle response settings, and can adjusting the cadence sensor sensitivity improve hill climbing performance? Are there any general guidelines or recommendations for adjusting throttle response time based on rider weight, terrain, and desired level of assistance?
