I live at the top of a monster hill, and the 99 N·m torque on this thing makes my commute feel like a flat road. The 20x4" tires give me way more confidence on gravel than my old bike ever did.

That torque number isn't just marketing hype—I actually felt the 99 N·m kick in while climbing a gravel path, and the 20x4" tires kept me planted the whole way.

I live at the top of a monster hill, but that 99 N·m torque makes the climb feel like flat ground every time. The battery holds up well for my whole commute, and the motor kicks in just when you need it.
