Plan on ground-level storage, a ramp instead of a lift, and a hitch rack rated well above standard e-bike weights. What the mass buys you is the dual drivetrain, the second battery, and a steel frame rated to 396 lb of payload.\u003c\/p\u003e\u003c\/details\u003e\n\u003cdetails\u003e\u003csummary\u003eDoes it have a warranty and who handles it?\u003c\/summary\u003e\u003cp class=\"sb-a\"\u003eSamebike covers the frame for 3 years and the battery, motors and other components for 1 year (battery prorated after the first year).
