Questions are welcome. No pressure, no bike jargon required.
The ride, not just the specs
There is a certain kind of freedom that starts when the pavement ends. The Checkpoint was built for exactly that feeling: comfortable enough to stay out longer, capable enough to keep going, and ready to carry what matters.
We love bikes that invite you to say yes to the extra mile. This is one of them.
What makes it special
The industry-leading TQ HPR 60 harmonic pin ring motor is super efficient with an amazing range-to-weight-to-speed ratio. It's ultra-compact, whisper-quiet, and offers a natural-feeling assist up to 28 mph with 50 miles of range (in eco mode). Plus, choose how much boost you get and when you get it with three assist modes.
Explore even farther with an optional 160Wh Range Extender that fits neatly in your bottle cage and gives you an extra 44% more range.
IsoSpeed technology soaks up fatiguing bumps in the road so you can ride stronger longer.
