Pros Reasonably priced, good distance range, well rounded performance, solid component specOutstanding 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 motor
Cons Heavy, sluggish handling at times, controls/display are difficult to readReadout 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, expensive
Bottom Line The well rounded and reasonably priced Giant Trance E+ 2 Pro takes home our Best Buy AwardThe 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-bike
