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 that’s 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 doesn’t 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. It’s concealed in the downtube, but it’s 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.

Slack or steep, the choice is yours
Install angle adjust headset cups (sold separately) to tweak the head tube angle a degree steeper or slacker to your liking — all without impacting your bottom bracket height.
