Lectric XP4 750 vs Aventon Level 3

The Lectric XP4 750 is the better pick for riders who want a folding frame, a torque sensor for natural pedal assist, and a 28 mph top speed. The Aventon Level 3 is the better commuter: a step-through frame, front suspension fork, suspension seat post, fenders, integrated lights and GPS tracking with an alarm. The XP4 carries more cargo on its rear rack and folds for storage or transit; the Level 3 rides more comfortably on rough pavement and is easier to mount. Owners of both praise the hydraulic brakes and quiet motors, but the XP4's 69-71 lb weight and the Level 3's 67 lb weight make neither easy to carry up stairs.

• Choose the Lectric XP4 750 if you need a folding bike for a car trunk or small apartment, want a torque sensor and a 28 mph top speed, or plan to haul heavy cargo on the rear rack.
• Choose the Aventon Level 3 if your riding is mostly commuting on mixed pavement, you want fenders, lights, suspension and GPS tracking out of the box, or you prefer a step-through frame.
