Fathom E+ 1 EX

This versatile new E-bike combines the flat handlebar control and front suspension of a mountain bike with the built-in utility of a city bike. With integrated lights, fenders and a rear rack for cargo, the Fathom E+ EX is made for active lifestyles.

Key Performance Factors

Integrated design

800Wh EnergyPak is integrated into the down tube. The RideControl Dash handlebar has display compatibility and control buttons mounted on the handlebar.

Total control

New SyncDrive Pro 2 motor technology gives you 400 percent of tunable power so you can adjust your E-bike to ride just the way you like. A 130mm suspension fork helps smooth out rough roads and bumpy bike paths.

Off-road accessories

With built-in fenders, a rear rack and integrated lights, this hardtail can do double duty as an everyday trail riding bike or a practical companion for longer treks and adventure rides on dirt.

Range

How far can I expect to ride on a single battery charge?

The range for a single battery charge can vary greatly depending on conditions such as the combined weight of the rider and cargo; wind resistance; tire pressure and tread profile; terrain and elevation changes; road or trail surface; outdoor temperature; maintenance of the E-Bike; and the condition of the battery.

The bar below gives an approximate range. Conditions are categorized as extreme, good and ideal. Extreme conditions typically occur when riding with a heavy load, strong headwinds or excessive climbs.

  • Weight
    The most accurate way to determine any bike’s weight is to have your local dealer weigh it for you. Many brands strive to list the lowest possible weight, but in reality weight can vary based on size, finish, hardware and accessories. All our bikes are designed for best-in-class weight and ride quality.
