>>1919448The amount of stress being put on a bicycle's headset area is completely different from an e scooter. There's a reason why competent manufacturers use steel for it.
>>1919449You obviously weren't there then for when Zero10x and Kaabo Mantis stems were snapping. They were breaking out of nowhere even for people who were underweight and not gapping curbs. Even Apollo even had to issue a notice for Phantom stems snapping due to using the wrong type of material. For the Burn-E issue people are speculating they used the wrong type of alloy or they aren't properly heat treated due to how they broke. But they shouldn't have been aluminum anyways for something that heavy with poor suspension geometry. Some of their aluminum stems are showing stress cracks like this one. Pure Chinesium.
