Overview
A chain drive with seven speeds links the pedals to the rear wheel, while an electric motor adds pedal assist on a carbon steel frame. Dual suspension, fat tires and dual disc brakes point it at trails.
Power, suspension at both ends and an upgrade path for the battery are what the listing leads with. What it does not give is a weight, a rider limit or a plain statement of which battery comes with which version.
Who it's for
Teens and adults who ride dirt paths and want suspension, wide tires and a headlight set. Riders comparing runtimes must confirm which battery goes with the version they pick. Shorter riders should ask about fit, as only a standard size is given.
Pros and cons
- Dual disc brakes
- Battery upgrade option
- Tool kit and charger included
- Battery capacity varies by version
- Bike weight not listed
Performance notes
A bigger battery adds range but also mass, so the choice of version changes both runtime and handling. Dual suspension and wide tires reduce impacts on unpaved ground, and two disc brakes spread braking effort across both wheels. Pedal assist adds motor power in step with pedaling.
