Additionally, the system is programmed to only work with the 360 WH TQ battery we’ve selected. Do not swap or use non-approved batteries on your Trek ebike to maintain safety and compliance.
What if I want more range?

Model Comparison Questions
How does this compare to the FX+ 2 model?
FX+ 2 is also a lightweight commuter e-bike model that utilises our Hyena Hub-drive system. While both are lightweight, the FX+ 7 has a larger battery (360 Wh vs 250 Wh), more torque (40 Nm vs 50 Nm), and more integration of lights, mudguards and a Quad Lock charging mount. If you are looking for a lightweight ebike without the additional range, integration and power of FX+ 7 – the FX+ 2 might work for you.
How does this compare to the Allant+ Models?
These models utilise a Bosch a Bosch mid-drive system instead of the TQ system on the FX+ 7. Typically, the Allant+ models will have higher battery capacity and torque specs than the FX+ 7 but the tradeoff will be weight. Allant+ models are usually 4.5 to 5.44 kg heavier than the FX+ 7. If light weight is a priority for your commute, the FX+ 7 is ideal. If you need more range without and extender or more power, you might want to explore the Allant+ family.
