To compare the e-bikes in this review, we subjected each model to the same rigorous testing process. Before testing, we identified the most critical performance attributes of electric bikes to establish our rating metrics. For each metric, we determined the best way to test and analyze each model's performance to compare the bikes. During testing, we took detailed notes, and after testing was completed, we rated each model based on cumulative scores and determined our award winners.
Ride
To assess the ride quality of the electric bikes in this review, we rode each bike for more than a month, gaining a feel for the ride and how component choices affect performance. We perform a variety of handling-specific tests to determine how the bikes compare. During our range test, our test rider rides nonstop for up to 3 hours on a test course with gently rolling hills and a mix of hard-packed surfaces, including pavement, gravel, and dirt. The extended length of the range test also allowed us to analyze the long-term comfort of each bike's geometry and touchpoints, such as the saddle and grips.
Every bike is run through a series of handling tests in a more controlled environment. Using our own closed parking lot, we set up cones and rode each bike in figure eights around them to assess low-speed handling and performance in tight turns. We brought each bike up to its top pedal-assisted speed and made large, sweeping turns. We tested braking performance by measuring the distance required to bring the bike from its top speed to a complete stop. We also rode each bike down a sustained hill to test the straight-line high-speed stability.
In addition to our handling tests, we also analyzed the performance of each bike's components, including the wheels, tires, and drivetrain. Additional features like lights, racks, and fenders were also considered based on their impact on the user experience.
Manufacturer Claimed Range vs GearLab Tested Range
The range of an electric bike refers to the distance it can travel on a single charge of its battery. Different battery sizes, motor power, rider weight, rider pedaling input, and terrain all contribute to how far a bike will travel before its battery is depleted. Due to these factors and variables, accurately testing and comparing the range of electric bicycles can be a challenge. To create a level playing field and minimize external variables as much as possible, we conduct all our range tests on the same course with the same weight rider in similar weather conditions. We set the bikes to their highest power setting and load our test rider to an even 180 pounds before each test. With the tires at the maximum recommended pressure, we set off using only the throttle, eliminating the variable of rider input to determine the absolute low end of each bike's range potential. These bikes can be ridden much farther when using their pedal-assist modes with a pedaling rider.
For testing accuracy, we use the same Garmin Edge 840 GPS-enabled cycling computer to track and log each test ride for consistency. For redundancy, we also track each ride with Ride with GPS, Apple Fitness, and Strava. These devices track our distance, elevation gain, time, average speed, and maximum speed. We then compiled all of our data for more detailed analysis.
Claimed Power vs. GearLab Dynamometer Tested Power
Electric power is the primary feature that distinguishes an e-bike from its non-electric counterparts. The power of a bike varies primarily based on the motor's size and wattage, as well as its electrical architecture. It stands to reason that a 750W (1HP) motor will be more powerful than a 250W motor, or a 52V system will supply more power than a 36V system. That said, we were also interested in the quality and consistency of the power output. To test the models' power output, we performed several tests using pedal assist and the throttle when applicable.
We test each bike's top speed (and speedometer accuracy) on flat ground by observing the speedometer, comparing it with a Garmin 840, and double-checking with a GPS app like Strava. We test acceleration by measuring the time it takes for the bike to reach its full speed from a complete stop on flat ground. We use a closed road with a steep (9%) incline to measure each bike's hill-climbing prowess and record the speed from flat ground to the apex of the hill.
A bike's motor is only as good as the software and sensors controlling it. To move past the manufacturer's claims, we put every bike through a multi-stage pedal assist (PAS) evaluation to see how “smart” the power delivery actually is.
Does the motor actually hit its promised top speed?In the world of Class 3 e-bikes, 28 mph is the industry standard—but in practice, “28” is often a suggestion. We test this by pushing each bike to its maximum support mode under high-intensity pedaling. While most bikes should theoretically cut off at the same speed, our 2026 testing continues to reveal "strays": Some motors taper off early (around 26 mph), leaving the rider to do the heavy lifting, while others let the assist linger slightly past the legal limit, providing a “punchier” feel at the top end.
Beyond experiential testing, we use a modified motorcycle dynamometer to precisely measure the power and torque delivered to the ground. We measure peak power in watts and graph it against peak torque in Nm. Peak power is often significantly higher than the nominal (or rated) power of the motor. By using a dynamometer, we push beyond the claims and feel of the bike and have hard data to compare.
Interface
An electric bike's interface encompasses all user interaction points: controls, display, and battery charging. Control systems for switching pedal assist modes vary widely in layout, ergonomics, and ease of use. We evaluated each model's controls extensively during range testing, handling tests, and everyday rides. Displays serve as the information hub, showing critical ride data to the rider. Options range dramatically from large LCD screens to minimal LED indicators. Advanced displays provide comprehensive information—elapsed time, current speed, pedal-assist level, remaining battery life, and more—all visible at a glance. Basic displays limit themselves to essentials like assist mode and battery charge. Some models enhance the experience further with companion apps featuring digital dashboards, extensive data tracking, and turn-by-turn navigation. Our preference leans toward well-positioned, easy-to-read LCD screens that deliver information quickly while riding.
Battery charging remains fairly consistent across the models we tested. Each bike includes a dedicated charger with a plug that connects to the battery's charging port. Most batteries can be charged while mounted on the bike or removed for off-bike charging and security. We charged each battery multiple times during testing to evaluate the charging port location, port cover design, and overall process convenience. We assessed ease of battery removal for both charging flexibility and theft prevention. Timing tests measured how long fully depleted batteries took to reach full charge. While some manufacturers offer faster charging for added convenience, this feature can shorten the overall lifespan of the battery.
Assembly
Purchasing from a physical bike shop usually includes professional assembly by a qualified mechanic. Online purchases, however, arrive partially assembled, typically around 85% complete, requiring buyers to finish the remaining steps themselves. Most consumer-direct brands keep these final steps simple and straightforward. If preferred, buyers can pay a local or mobile bike mechanic to handle the assembly.
We received most electric bikes directly from manufacturers or third-party sellers. At our GearLab bike shop, we unboxed and assembled each one ourselves to mimic the typical consumer experience. Throughout the process, we documented every step—from opening the box to the first ride—noting any unclear instructions or inadequate tools. We evaluated both printed manuals and online resources for clarity and helpfulness. Time-lapse cameras captured each assembly, allowing us to record exact completion times and identify any potential challenges buyers might face.
