When it bends, cracks, strips at the pedal thread, or works loose on the spindle, you feel it every stroke — a click, a wobble, or a pedal that no longer sits square under your foot.\u003c\/p\u003e\n\n\u003cp\u003eThis is the direct replacement crank arm set for Ridstar electric bikes — \u003cstrong\u003eboth the left and right arm together.\u003c\/strong\u003e It is not a wear item you swap on a schedule; it is the part you need after an impact, a stripped pedal thread, or a spindle that has chewed up the original. \u003cstrong\u003eSelect your model and you get the matching set the first time.\u003c\/strong\u003e\u003c\/p\u003e\n\n\u003c!-- ============================================ --\u003e\n\u003c!-- SELECT YOUR MODEL --\u003e\n\u003c!-- ============================================ --\u003e\n\u003ch3\u003eSelect Your Model\u003c\/h3\u003e\n\n\u003cp\u003eUse the dropdown above to choose the crank arm set that matches your bike.

Once the aluminium thread is gone, the arm has to be replaced — it cannot be safely re-tapped for the same pedal.\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eBent or cracked arm\u003c\/strong\u003e — After a hard impact, curb strike, or drop, a crank arm can bend or crack. A bent arm throws off your pedal stroke and puts uneven load on the bottom bracket. A cracked arm can fail without warning.\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eLoose on the spindle\u003c\/strong\u003e — If the arm keeps working loose even after you re-torque the bolt, the square or splined interface where it meets the spindle may be worn out (rounded). A fresh arm restores a tight, click-free fit.\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003ePersistent clicking or creaking\u003c\/strong\u003e — A worn crank-arm-to-spindle interface creates a rhythmic click that follows your pedal cadence.

Left and right are not interchangeable — the pedal threads are opposite-handed — so having the matched pair means everything threads in and stays put.\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eDirect OEM replacement\u003c\/strong\u003e — The same crank arms Ridstar uses on the bike, not a generic substitute that may sit at the wrong depth or use a different interface.\u003c\/li\u003e\n\u003c\/ul\u003e\n\n\u003c!-- ============================================ --\u003e\n\u003c!-- WHAT'S INCLUDED --\u003e\n\u003c!-- ============================================ --\u003e\n\u003ch3\u003eWhat’s Included\u003c\/h3\u003e\n\n\u003cul\u003e\n  \u003cli\u003e1 × Ridstar crank arm set — left and right arm, for the model you select\u003c\/li\u003e\n\u003c\/ul\u003e\n\n\u003cp\u003e\u003cstrong\u003eNot included:\u003c\/strong\u003e Pedals, crank bolts, bottom bracket, or tools.
