Pros Outstanding battery life, whisper quiet motor, just right geometry, intuitive operationGood controls, huge distance range, confidence inspiring at speed, good component specVery nice build, stealthy looks, hard-charging downhill performanceLightweight for an e-bike, normal trail bike feel, range extender battery, quiet motorGreat build spec, very capable downhill, eye-catching design, integrated battery, Shimano E8000 powertrain
Cons Readout display not standard feature, SRAM Guide brakes not powerful enough, reported motor failuresHeaviest in test, sluggish at low speedsExpensive, sluggish handling at times, came setup with tubes in tiresLess battery storage capacity, less powerful drive unit, expensiveExpensive, heavy, lethargic climber, unimpressive range
Bottom Line The 2020 Specialized Turbo Levo Comp checks in for the third consecutive time as Editor's Choice thanks to class-leading range, power and innovationConfidence and stability, the Bulls E-Stream EVO AM 4 likes to party and can do so for a long time thanks to its large battery and distance rangeThe enduro-oriented YT Decoy is capable of charging the descents as hard as you wantThe new Turbo Levo SL splits the difference between a regular trail bike and a full-power e-bikeWell-built with high-end components and the rock solid Shimano E8000 powertrain, the 2020 Commencal Meta Power 29 Team is a capable ebike but is held back by its limited range and weight
