Our verdict

A single-speed fat tire e-bike offered with two battery sizes, with dual suspension and dual disc brakes. Check which battery your listing option carries, and the minimum height field looks wrong.

Overview

Commuting streets and off-road trails both fall within what this high carbon steel e-bike is meant for. It has dual suspension, dual disc brakes, a digital display and an adjustable seat and handlebar.

Two battery sizes and a stated skill level of advanced point to a bike meant for riders who want range. The single speed means no gears for steep climbs, and the height entry in the spec table is clearly mistaken.

Who it's for

Experienced riders using one bike for city streets, gravel and snow, who accept a single speed. First-time e-bike buyers may prefer something with gears. Assembly is required.

Pros and cons

Pros
  • Two battery options
  • Dual disc brakes
  • Adjustable seat and handlebar
Cons
  • Single speed only
  • Minimum height field unclear

Performance notes

With one speed there is no gearing to ease steep climbs, so the motor does that work. A large battery lengthens range at the expense of added weight. Fat tires and dual suspension handle gravel, snow and city roughness.
