Don’t treat a bike like a car, they are not the same thing.
Contemporary EV sound is designed for linear velocity. But riding a bike is rarely a linear experience; it’s a dynamic experience over several axes. With traditional bike acceleration and braking is key to sound but adding additional layers of sound while cutting corners is a next-level experience.
But the key to developing the solution is designing a technical solution that makes the intention of the driver heard. A slow throttle or an aggressive approach do not only sound different but also make the difference for road users. Different audible intentions trigger different responses.
From flat out acceleration to tiny throttle tweaks while in a tight hairpin, you and other road users need to feel and hear the difference.
