Hey e-bike enthusiasts, if you've got a TSDZ2B mid motor that's starting to sound a bit rough, this gear assembly is your fix! Weighing only 94g, this compact replacement gear is built from premium nylon and steel that can handle the torque without deforming or wearing out quickly. The reduction gear design provides smooth power transfer while being surprisingly lightweight and reliable. Installation is straightforward - just remove your old worn-out gear and pop this new one in place. No special tools needed, which is great for home mechanics. The craftsmanship is seriously solid, with strong load-bearing capacity that'll keep you riding smoothly for miles. Perfect for mountain bike conversions or anyone who puts serious miles on their e-bike. I've used these in several TSDZ2B rebuilds and they've held up better than the original parts. Pro tip: Keep one of these on hand as a spare if you're a heavy rider or do lots of hill climbing - it's cheap insurance against being stranded with a noisy motor!
