Circuit Speed Test
The Trek FX+ 2 is not built to be a high-speed electric bike, but rather a practical and efficient commuter. That said, it performs respectably in a circuit speed test, particularly in typical urban environments where agility and controlled acceleration matter more than top speed.
During a standard circuit speed test, which includes a combination of flat streets, slight inclines, and stop-and-go segments, the FX+ 2 demonstrates a consistent and stable ride. Powered by a 250-watt HyDrive rear hub motor, it offers pedal-assist support up to 20 mph (32 km/h), which is the legal limit for Class 1 e-bikes in many regions.
Acceleration:
From a standstill, the motor engages smoothly. The torque isn’t aggressive, but it’s sufficient for getting up to speed in a reasonable amount of time, ideal for city riding where sudden bursts of power can be unnecessary or unsafe. Riders can expect to reach top assisted speed in under 10 seconds on flat ground, depending on leg power and weight.
Speed Holding:
On flat terrain, the bike comfortably maintains its top assisted speed when using the highest assist level. The assistance is subtle and natural, not jerky or overly mechanical, which contributes to a relaxed but efficient ride.
Hills and Inclines:
The FX+ 2 handles gentle inclines adequately. The motor’s 40 Nm of torque is modest compared to mid-drive motors, but it gets the job done for short, moderate climbs. Riders in hillier areas may find themselves dropping to lower gears and adding more personal pedal effort, as the hub motor isn’t as torque-heavy as other drive systems.
Braking at Speed:
Even when traveling at max speed, the hydraulic disc brakes perform with confidence. They bring the bike to a quick and stable stop with minimal effort, a critical feature for urban circuits where sudden stops are common.
In summary, the Trek FX+ 2 isn’t designed to be the fastest e-bike on the market, but in a circuit speed test focused on real-world conditions, it delivers reliable, controlled performance that suits city commuters. Its steady acceleration, predictable top speed, and dependable brakes make it a strong choice for riders prioritizing efficiency and comfort over raw speed.
Range Test & Battery Performance
When evaluating the Trek FX+ 2’s battery and range performance, it’s essential to understand the type of riding it’s designed for: efficient, everyday commuting and light recreational use. The FX+ 2 is powered by a 250Wh internal battery paired with a 250W HyDrive rear hub motor, which together offer a balance between weight, simplicity, and practical range.
Real-World Range Test
Trek advertises a maximum range of up to 35 miles (56 km) on a full charge under ideal conditions. In real-world testing, the actual range varies based on several key factors:
-
Assist level used: There are typically three assist levels—Eco, Normal, and High. Using Eco mode conserves the most energy and can achieve close to the full 35-mile range, while High assist significantly shortens that to about 15–20 miles depending on terrain and rider effort.
-
Rider weight and cargo: Heavier riders or those carrying loads on the rear rack will see a reduction in range.
-
Terrain and elevation: Flat urban routes allow for longer range, whereas hilly areas or routes with frequent stops consume more battery power.
-
Temperature: Cold weather can impact battery efficiency and decrease range.
On average, most riders can expect:
-
30–35 miles in Eco mode
-
20–25 miles in Normal mode
-
15–20 miles in High mode
Battery Charging and Convenience
The 250Wh battery is fully integrated into the downtube, giving the bike a clean look. It is non-removable, meaning the entire bike must be brought near a power outlet for charging. This design is sleek and helps keep weight down, but it could be inconvenient for users who live in walk-up apartments or need to charge in a separate location.
Charging time is approximately 4 hours from empty to full. Trek also offers an optional Range Extender—an additional external 250Wh battery that doubles the overall range. This accessory is ideal for riders planning longer trips or commuting over greater distances regularly.
Battery Management System
The FX+ 2 includes a smart battery management system (BMS) that helps optimize performance, prevent overcharging, and extend overall battery life. Trek designed the system to require minimal user maintenance, with diagnostic tools available through authorized Trek dealers.
Hill Test – Trek FX+ 2 Climbing Capability
The Trek FX+ 2 is a lightweight electric bike built primarily for city use, and its hill-climbing performance aligns with that focus. Rather than being made for steep or mountainous terrain, it handles gradual inclines and rolling hills with ease. Powered by a 250W HyDrive rear hub motor that delivers 40Nm of torque, it offers sufficient assistance for everyday hills, though it may struggle a bit on steeper gradients.
Mild to Moderate Hills (0–6% Gradient)
On gentle inclines, the FX+ 2 performs comfortably. When using the higher pedal-assist levels, the motor engages smoothly and helps maintain a consistent pace without forcing the rider to overexert. In this type of terrain, the 9-speed Shimano drivetrain also contributes to efficient gear changes, allowing the rider to adjust cadence effectively.
In most cases, riders won’t need to stand up or shift aggressively to get over these mild slopes. The FX+ 2 keeps momentum well, making it suitable for neighborhoods with rolling terrain or cities with modest elevation changes.
Steep Hills (7–12% Gradient and Above)
On steeper inclines, the FX+ 2 starts to show its limitations. The rear hub motor lacks the high torque output of mid-drive motors found in more climb-focused e-bikes. As a result, the bike relies more heavily on the rider’s own pedaling effort, especially at lower speeds.
Riders will likely need to shift into lower gears early and maintain a steady cadence to climb effectively. In High assist mode, the motor does provide noticeable help, but it may not be strong enough to carry heavier riders or those carrying cargo up extended or very steep grades without significant leg input.
Traction and Stability
Thanks to its balanced geometry and relatively lightweight frame, the FX+ 2 maintains good control on inclines. Its tires provide decent grip on paved surfaces, and the hydraulic disc brakes ensure safe control during descents, offering smooth and consistent braking even after sustained use on downhill segments.
Bottom Line
The Trek FX+ 2 can handle hills, but it’s best suited to environments with moderate elevation changes. While it’s not a powerhouse climber, it gets the job done for most city and suburban riders. Those who frequently ride in hilly areas or need to conquer longer, steeper climbs may want to consider adding the optional Range Extender for extra power or exploring mid-drive e-bike options with higher torque ratings.
Safety and Brake Test – Trek FX+ 2
When it comes to rider safety, the Trek FX+ 2 is equipped with features designed to offer control, confidence, and visibility—critical factors for urban and commuter riders. One of the standout aspects of this bike is its reliable braking system, which performs consistently in both dry and wet conditions.
Hydraulic Disc Brakes Performance
The FX+ 2 comes with Tektro hydraulic disc brakes, known for their responsive stopping power. In safety tests across various speeds and terrain types, the brakes provide strong, steady deceleration. Whether coming to a stop from 20 mph on flat pavement or slowing down on a downhill stretch, the brakes engage smoothly without feeling overly abrupt or harsh.
Braking Distance
On dry pavement, the bike can come to a full stop from 20 mph within approximately 12–15 feet (3.6–4.5 meters), depending on rider weight and conditions. In wet or slippery environments, the braking distance slightly increases, but the hydraulic system still offers better control than mechanical brakes or rim-based systems.
Brake Modulation
A key feature of the FX+ 2’s braking system is its excellent modulation. Riders can apply gradual pressure to slow down smoothly or squeeze harder for an immediate stop—an essential trait for safe riding in traffic or during unexpected hazards. The levers are ergonomic and easy to grip, even with gloves on, making them accessible to a wide range of riders.
Visibility & Built-in Safety Features
Beyond braking, the Trek FX+ 2 includes several built-in safety elements that enhance visibility and protection:
