TQ offers a smooth, quiet, natural-feeling pedal assist, has 50 Nm torque to climb up hills and comes as a lightweight package.

Can you add a Range Extender?

Yes, the TQ HPR Range Extender Battery is compatible. It offers an additional 250 Wh of battery power to increase range.

How accurate is the TQ power meter?

While the TQ power meter is accurate enough for the TQ system to provide smooth, natural assist, it is not accurate enough to provide athletic training data. For training purposes, we recommend a pedal-based power meter system.

How long does it take to charge the battery?

The TQ battery charges in 2 hours with the supplied TQ charger.

Is the battery removable?

The battery is removable by an authorised Trek dealer. Do not try and remove the battery at home.

Can you swap for a bigger battery?

No, the FX+ 7 frame was designed to fit the 360 Wh battery from TQ. Larger capacity batteries typically have larger dimensions that will not fit in the frame. 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?

We offer the TQ Range Extender that fits into a water bottle cage and adds an additional 160 Wh of battery life (160 Wh Range Extender + 360 Wh Internal battery) and increases your range.

Does the Quad Lock mount charge my phone?

Can I swap the handlebar?

No, the handlebar on this model is part of an integrated system with the stem and headlight. We do not recommend replacing it.

Can I swap the rear rack?

No, this rack is designed to fit with the frame and mudguards for a seamless look. Additionally, it houses the rear light and has channelling for the light wire.

Can I attach a trailer to the bike?

What is the QL3.1 system?

This is a hookless mount for side bags so the bags can easily be removed and are comfortable for carrying.

Can my rail mount bag be upgraded to QL 3.1?

No, you cannot convert a rail mount to QL3.1.

Does this bike include MIK Studs?

Yes, the FX+7 includes the studs for MIK side mounting

Is the rear rack compatible with standard pannier bags?

The MIK SIDE washers and fasteners can be removed to fit some standard-rail pannier side bags. For mounting on the ovalised rails, you may need rubber shims to prevent rattling or rubbing. Also check that the lower hook/strap can fit onto the rack lower rail to keep the bag from swinging into the wheel.

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.
