Does the eBike have a speed limiter to comply with local regulations and, if so, how does it handle situations where the rider is going downhill or on a slight incline, potentially reaching speeds above the allowed limit due to gravity or momentum? What mechanisms are in place to prevent the bikes motor from assisting the rider in such situations, and how do they impact the overall performance and usability of the eBike? Are there any differences in how speed limiters work on eBikes designed for different countries or regions with varying regulatory requirements, and what implications might this have for riders who travel or ride in multiple jurisdictions? Can manufacturers ensure that their speed limiters comply with the specific regulations in each country while still providing a seamless riding experience for users?
