Trek FX Plus 1

Manufacturer: Trek

The Trek FX Plus 1 is an aluminum-frame electric bike built around a clean, integrated design with internal cable routing and an in-frame battery that keeps the overall silhouette tidy and uncluttered. It comes equipped with both a display and a dedicated smartphone app, along with front and rear lights for year-round usability.

Powering the bike is a 500W hub-drive motor delivering up to 60 Nm of torque, with a top assisted speed of 32 km/h and a maximum range of 80 km per charge. The 520 Wh battery takes around 5.5 hours to fully charge and is housed within the frame. Shifting is handled by an 8-speed drivetrain, while braking relies on hydraulic disc brakes. Riders can choose between eco and turbo assist modes, and the dual pedal sensor setup combines cadence and torque sensing for responsive power delivery.

Pros
  • Dual pedal sensing with both cadence and torque detection allows for more responsive and natural power assistance
  • Hydraulic disc brakes provide reliable stopping performance in varied conditions
  • Both eco and turbo assist modes give riders direct control over power usage and range
  • Internal cable routing and an in-frame battery contribute to a cleaner, less cluttered frame design
  • Integrated front and rear lights make the bike usable in low-light conditions without additional accessories
  • An on-board display combined with a dedicated smartphone app offers convenient ride monitoring
Cons
  • The battery is not removable, which means charging must be done with the bike stationary near a power source
  • At 22,100 g, the overall weight is substantial, which can make handling or transporting the bike more difficult
  • No GPS is built in, so location tracking or navigation relies entirely on an external device
  • The lack of any suspension front or rear means the ride may feel less forgiving on uneven or rough surfaces
  • No anti-theft features are included, requiring separate solutions for security
Who is this for?

This bike is well suited to adult commuters and everyday urban riders who want a practical, capable electric bike for regular use. The 500W hub-drive motor with eco and turbo modes makes it adaptable for both relaxed commutes and more demanding routes, while the 80 km range per charge supports longer daily distances without frequent recharging. Riders who appreciate a tidy, well-integrated build will find the internal cable routing and in-frame battery appealing, and the inclusion of integrated front and rear lights alongside a smartphone app makes it a convenient all-in-one option for city or suburban riding.

Who is this NOT for?

Riders seeking an off-road or trail experience will find this bike limiting, as it has no front or rear suspension to absorb rough terrain, making it poorly suited to unpaved paths or technical surfaces. The non-removable battery is a drawback for anyone without easy access to charge the bike in place, such as those living in apartments without ground-floor storage. At 22,100 g, the bike is also not practical for users who need to carry or lift it regularly, such as those navigating stairs or loading it onto public transport frequently.
