Are suspension lockout systems on electric mountain bikes truly necessary for climbing and sprinting, or are they just a marketing gimmick designed to increase sales by making riders feel like they need yet another feature to be competitive? Is the weight and cost of these systems really justified by the minimal performance gains, or are riders just getting caught up in the hype surrounding the latest and greatest technology? Can anyone provide some actual data or testing results that show a significant improvement in climbing or sprinting performance when using a suspension lockout system on an electric mountain bike?
