I recently upgraded my e-bike with some titanium bolts and a battery-powered rock light, and honestly both were worth it. The titanium bolts feel super high quality, lightweight, and way stronger than the stock hardware, plus they gave the bike a really clean custom look without worrying about rust. Installation was simple and everything fit perfectly. The rock light was also a great addition — it’s bright, durable, and makes night rides look awesome while adding extra visibility. The battery life lasts longer than I expected, and mounting it was easy with adhesive and straps. Overall, both upgrades made the bike feel more premium and personalized, and I’d definitely recommend them to anyone wanting better style and performance on their build.
