Pros and cons

- 20x4.0 inch puncture-resistant tires for sand, dirt and snow
- Front and rear suspension with dual mechanical disc brakes
- Three ride modes plus app-adjustable top speed
- No key start, add a separate bike lock
- Ships speed-limited to 20mph until adjusted through the app
Performance notes
The 1500W peak motor and 90 N.m of torque are rated to climb inclines up to 30 degrees, with the 20x4.0 inch tires providing traction on sand, dirt and snow. Dual mechanical disc brakes and front and rear suspension handle stopping and rough-surface control, while three modes, throttle-only, pedal-assist and manual, let riders choose how much the motor contributes. AetherGlide rates range at 50-60 miles in electric mode, though that will vary with rider weight and terrain, and a reviewer confirms the bike arrives limited to 20mph until adjusted in the app.
