Jasion EB5 Ultra Long-Range Full-Suspension Fat Tire E-Bike

Built Around Battery Capacity, Not Just a Bigger Motor

The Jasion EB5 Ultra is a full-suspension fat tire electric bike designed for riders who prioritize battery capacity, wider tires, stronger peak power, and more capability on mixed everyday terrain. Its 52V 20Ah removable battery provides 1,040Wh of stated capacity, making it a model to consider for longer commutes, outdoor routes, rural roads, and weekend rides that go beyond short neighborhood trips.

Unlike lightweight folding e-bikes designed mainly for quick storage and short urban travel, the Jasion EB5 Ultra uses a larger 26-inch fat tire platform, full suspension, a reinforced frame, and a higher-capacity battery. This makes it more relevant for riders who want one e-bike that can cover paved roads, gravel sections, hard-packed trails, snow, sand, and uneven streets.

70-Mile Claimed Range for Longer Riding Plans

The Jasion EB5 Ultra uses a removable 52V 20Ah lithium-ion battery with 1,040Wh of stated capacity. Jasion lists a maximum claimed range of up to 70 miles. This figure represents favorable riding conditions, and actual range will vary according to pedal-assist level, speed, throttle use, rider weight, cargo, terrain, elevation, wind, weather, tire pressure, and battery condition.

A larger battery can be especially useful for riders who do not want to recharge after every short trip. It may suit longer commutes, weekend rides, rides with changing terrain, camping trips, or users who prefer to keep more battery reserve available for hills and higher-assistance riding.

2500W Peak Power for Steeper and Heavier Routes

The Jasion EB5 Ultra is listed with up to 2,500W of peak motor power and at least 75Nm of torque. This power specification is intended to provide more confident support for starts, hills, loose surfaces, heavier riders, and cargo-carrying rides than lower-output commuter e-bikes.

The listed maximum speed is up to 33 MPH. Riders should check local regulations before using the bike on public roads, bike lanes, shared-use paths, or public trails. Speed limits, throttle access, helmet rules, registration requirements, and e-bike classifications vary by state and municipality.

Full Suspension for Rougher Roads and Mixed Terrain

The Jasion EB5 Ultra combines a heavy-duty dual-crown front fork with a 160mm enclosed rear shock. Together with its 26 × 4.0-inch fat tires, this setup is designed to help reduce the impact of broken pavement, gravel, uneven trails, rough rural roads, and other mixed riding surfaces.

The fat tires provide a larger contact area than standard commuter tires, which may be useful on sand, packed dirt, snow, and loose gravel. However, this is still not a dedicated technical mountain bike for aggressive downhill riding, large jumps, or advanced singletrack terrain.

Hydraulic Braking and Mechanical Control

The Jasion EB5 Ultra uses hydraulic disc brakes with 180mm rotors. Hydraulic brakes are designed to provide more consistent braking control than basic cable-operated disc brakes, which can be especially relevant on a larger, heavier fat tire e-bike.

The bike also includes a Shimano 7-speed drivetrain and five pedal-assist levels. This combination gives riders more options for adjusting cadence and motor assistance across flat roads, hills, changing wind conditions, and mixed terrain.

Daily Equipment for More Than Recreation

The Jasion EB5 Ultra includes a rear rack, full-coverage fenders, a high-visibility front headlight, and a brake-activated rear light. These features help position it as a practical transportation option as well as a recreational fat tire e-bike.

The rear rack can be used with compatible panniers, cargo bags, baskets, groceries, commuting equipment, or camping gear. The listed maximum total payload capacity is up to 330 lb, including the rider, battery, and carried cargo. Confirm accessory compatibility and rack-specific load limits before carrying heavier items.

Fit, Weight, and Storage Before You Buy

The Jasion EB5 Ultra weighs approximately 91 lb. This is not a lightweight e-bike and may not be practical for users who need to lift a bike upstairs, mount it on a lightweight vehicle rack, or store it in a narrow indoor area.

The listed recommended rider-height range is approximately 5’6″ to 6’7″, with a minimum seat height of 35 inches and a maximum seat height of 39 inches. Riders outside this range, or riders who prefer a low-step frame, should compare step-through alternatives before purchasing.

Who Is the Jasion EB5 Ultra For?

The Jasion EB5 Ultra may suit taller riders, long-distance commuters, outdoor riders, and fat tire e-bike buyers who want high battery capacity, full suspension, hydraulic brakes, stronger peak motor output, and a large 26-inch platform. It may be particularly relevant for users who ride on a mix of pavement, gravel, packed dirt, snow, or uneven roads.

It can also suit riders who need practical utility features such as a rear rack, fenders, lights, and a higher total payload capacity, but do not want to move to a dedicated cargo e-bike.

When to Consider Another Model

Choose a smaller folding e-bike if apartment storage, frequent car transport, public transit, or easy lifting is your top priority. Choose a lower-step commuter e-bike if you need easier mounting and dismounting. Choose a dedicated e-mountain bike if advanced trail geometry and technical off-road performance are your primary needs.

The Jasion EB5 Ultra is best understood as a large, long-range, full-suspension fat tire e-bike for riders who want more capability, cargo flexibility, and battery capacity than a basic city commuter model provides.
