Group 1: New National Standard Implementation - The new standard increases the weight limit for lead-acid battery models from 55 kg to 63 kg, improves braking performance, and enhances anti-tampering requirements for controllers [1][4]. - The transition period from September 1 to November 30 allows for the sale of old standard models, but from December 1, all production of non-compliant models must cease [5][7]. Group 2: Market Reactions - Following the implementation of the new standard, there has been a noticeable market reaction, including price increases for old standard models and efforts by dealers to clear inventory [2][5]. - Some dealers report a shortage of old standard models as they are being sold out quickly, while new standard models have yet to arrive in stores [6][8]. Group 3: Consumer Experience and Concerns - Consumers are facing practical issues such as speed adjustments and model choices due to the new regulations, with some expressing a desire for higher speed limits [3][8]. - The new standard aims to address safety concerns, particularly regarding fire hazards, by limiting the plastic material proportion in bicycles to no more than 5.5% of the total weight [4][9]. Group 4: Technical Adjustments and Features - The new standard introduces features like optional Beidou positioning and dynamic safety monitoring, enhancing user experience and safety [4][9]. - The standard also includes measures to combat illegal modifications, raising the technical barriers for such practices [3][4]. Group 5: Industry Perspectives - Industry stakeholders acknowledge the necessity of the new fire safety requirements but express concerns about the potential increase in production costs due to stricter material regulations [9]. - There is a consensus among dealers that while the new standard improves safety, further adjustments may be needed regarding speed limits and weight restrictions for larger models [8][9].
