Do Electric Bikes Have Gears? (How to Shift Without Snapping Chains)

Yes, the vast majority of electric bikes feature mechanical gears—typically 7 to 11-speed derailleur cassettes or internal gear hubs—operating alongside electric motor assist levels. Shifting gears on an e-bike requires momentarily easing off rider pedal pressure so the electric motor does not apply 70 to 90 Nm of torque against changing sprockets, which prevents chain snap and cassette teeth shearing. Match lower mechanical gears for hill climbing and higher gears for cruising above 20 MPH.
