    • Better traction on loose surfaces
    • Added riding comfort
    • More riding versatility
    • Know the trade-offs  (weight & rolling resistance)
    • Built around the Fastron platform (750W, 26 × 4.0", 3.14" front suspension)

    How to Choose the Right Fat Tire Electric Bike

    Fat tires are only one part of the decision. Compare your riding routes, tire size, frame design, and carrying needs before you buy.

    1. Start With Your Riding Routes

      Think about where you ride most often.

      • City streets, errands, and light gravel: Sprint.
      • Gravel roads, packed dirt, and mixed-terrain rides: Fastron SO or ST.
      • More demanding technical trails: Explore our off-road electric bikes.
    2. Compare Tire Size and Wheel Setup

      Not all fat tire electric bikes use the same tire dimensions.

      • 26 × 4.0-inch tires: Fastron SO and ST offer a full-size fat tire setup for mixed-terrain riding.
      • 20 × 3.0-inch tires: Sprint uses a compact wide-tire setup for everyday routes and utility riding.

      Consider wheel size, frame geometry, and intended terrain together.

    3. Choose Your Frame Style

      • Step-Over: Choose Fastron SO if you prefer a traditional top tube and step-over frame.
      • Step-Through: Choose Fastron ST if you prefer easier mounting and dismounting.
      • Utility Frame: Choose Sprint if you want an integrated 3-in-1 rear mount for compatible cargo or passenger accessories.
    4. Check Weight and Carrying Capacity

      Always calculate your combined rider and cargo weight.

      • Fastron SO and ST: 300 lb total weight limit.
      • Sprint: 275 lb total weight limit.
      • Sprint rear mount: Maximum 55 lb load.

      Also consider the bike's own weight when lifting, transporting, or storing it.

    Frequently Asked Questions About Fat Tire eBikes

    A fat tire electric bike, sometimes called an electric fat bike, uses wider tires with more air volume and a larger contact area than standard bicycle tires. Leoguar's Fastron SO and ST use 26 x 4.0-inch tires, while the Sprint uses 20 x 3.0-inch tires.

    Yes. Fat tire electric bikes can work well for everyday commuting, especially if your routes include broken pavement, gravel paths, or uneven roads. However, wider tires can add weight and rolling resistance.

    Choose the Fastron SO if you prefer a step-over frame, the Fastron ST if you want easier step-through access, or the Sprint if you mainly ride in urban or suburban areas and want a 3-in-1 rear mount.

    The Fastron SO and ST offer an advertised range of up to 60 miles, while the Sprint offers up to 55 miles. Actual range depends on rider weight, cargo, terrain, speed, assist level, tire pressure, and weather.

    The Fastron SO and ST each have a 300 lb total weight limit, including the rider and cargo. The Sprint has a 275 lb total weight limit, with a separate 55 lb rear-mount limit.

    The Fastron SO and ST ship with a default speed setting of 20 mph. They can be unlocked through the display settings to reach up to 28 mph where local rules allow. The Sprint has a 20 mph top assisted speed.

    Fat tires can improve flotation on suitable packed snow and firmer sand. However, they do not guarantee traction on ice, deep powder, or very soft sand. Tire pressure, tread, surface conditions, and riding technique all affect control.

    Requirements vary by state and local riding rules. They may depend on the bike's speed configuration, motor specifications, and where you plan to ride. Check local requirements for the exact configuration before riding.

    Leoguar electric bikes include a 2-Year Limited Warranty covering electrical components and a 14-Day Trial. A restocking fee may apply to returns. Review the full warranty and return policies for coverage and exclusions.
