상품 특징

• 🛠️ All-in-One Square Taper Crankset – Integrated design with left crank arm, right arm & chainring combo, plus double-layer plastic chain guard. Fits 9/16" pedals. Compatible with single speed, 6/7/8 speed electric bikes, city commuters, folding bikes, fat tire bikes, and mountain bikes.
• ⚙️ Strong Steel Chainring & Forged Aluminum Arms – Chainring made of high-strength steel for long-lasting wear. Crank arms use forged 6061-T6 aluminum alloy – a premium material that stays lightweight, resists rust, and resists bending under heavy e-bike torque. Built for daily commuting and electric bike use.
• 🛡️ Double-Layer Chain Guard – Keeps chain from slipping off, stops chain grease from dirtying your pants, and gives your bike a clean look. Great for riders who want a worry-free ride without messy trouser legs.
• 📏 Multiple Length & Tooth Options – Choose from 152mm, 160mm, 165mm, 170mm, or 175mm crank arms and 46T, 48T, or 52T chainring. Perfect for customizing your bike’s gear ratio and fit – whether you need shorter cranks for folding bikes or longer ones for mountain bikes.
• 🔧 Easy DIY Installation – Square taper design fits most standard bottom brackets. No special tools needed (basic bike tools work). Before ordering, check your bike’s bottom bracket type and chainstay clearance. Direct replacement for worn or broken crankset.
