Overview

An adult electric bike from YVY built around a high-power motor rated between 1000W and 3000W depending on configuration, with 20-inch fat tires and a UL2849-certified battery system.

The K20Max spec sheet describes a 3000W motor with an 80 N.m torque rating and a 38 MPH top speed, positioning this as a higher-power ebike for hill climbing and mixed terrain rather than a light commuter. Range figures come from YVY's own battery specs: up to 55-70 miles on pure electric power and 90-120 miles with pedal assist, though real-world range depends on rider weight, terrain, and mode used.

  • 3000W peak motor, 38 MPH top speed
  • 52V 40Ah removable battery
  • 20-inch fat tires
  • UL2849 certified

Who it's for

Suited to riders wanting strong motor power for hills and long battery range for extended trips, across pavement, trail, or snow given the fat tire setup. Less suited to riders who want a lightweight, easy-to-store ebike, since this is a higher-power build with a large detachable battery.

Pros and cons

Pros
  • Detachable 52V 40Ah battery for flexible charging
  • Dual suspension and hydraulic disc brakes
  • Three ride modes plus 7-speed gearing
  • UL2849 certified battery system
Cons
  • Large battery and motor add weight versus standard ebikes

Performance notes

The dual motor setup and 7-speed transmission work across three modes, pure electric, pedal assist, and pedal only, letting torque delivery adjust to hills versus flats. Dual front suspension and hydraulic disc brakes are meant to handle rough terrain, while the 52V 40Ah battery is removable for charging off the bike.
