TQ-HPR50 small, quiet, mighty

The TQ-HPR50 motor is super-efficient with an amazing power-to-weight ratio. Most motors use gears and belts that take up space and can make noise or break. The TQ-HPR50 uses a harmonic pin-ring drive transmission thats small, ultra-quiet and unbelievably natural-feeling.

Range Extender

Give yourself 40% more range with an optional 160wh external battery. It fits in a standard bottle cage and doesnt require any complicated wiring or special mounts.

Connect, customize, calculate

The Trek Central app seamlessly connects with your bike for custom motor tuning, activity tracking and more ways to analyze and personalize your ride. You even get navigation features and real-time range calculations.

Removable battery

The 360 Wh battery gives you power for 2-5 hours. Its concealed in the downtube, but its still easy to remove for more convenient charging.

Active Braking Pivot

Active Braking Pivot allows our engineers to tune how the suspension reacts to acceleration and braking forces independently. That means you get more confident control when you need it most.

Transition to transmission

SRAM Eagle T-Type transmission mounts directly to the frame, skipping that pesky derailleur hanger of yesteryear. This makes for a more robust system thats not only cleaner looking, its also more precise under load, and easier to set up.
