Product description

The FavoriteBikes StormX is a fat tire e-bike built for riders who want traction, cargo capacity, and year-round versatility. Available through Costco Canada or directly from FavoriteBikes, it pairs 26" × 4.0" Wanda tires with a removable 46.8V 19.6Ah (917Wh) battery and a welded rear rack. The wide tires add grip and stability on loose surfaces such as snow, sand, gravel, and rough backroads, while the rack carries secured gear within the bike’s 330 lb / 150 kg total load limit.

For riders choosing between a commuter and an all-terrain e-bike, the StormX prioritizes all-terrain utility over smooth-pavement commuting. Its 48V / 500W Favorite Smart System hub motor includes a built-in temperature sensor, and the LTWOO 8-speed drivetrain uses an 11–32T cassette for varied routes. In its Canada configuration, the StormX provides assistance up to 32 km/h.

Why riders choose the StormX

  • 26" × 4.0" Wanda fat tires for added traction and stability on loose, uneven surfaces.
  • Removable 917Wh battery that slides out for indoor charging; a full charge typically takes 3–6 hours.
  • Welded rear rack rated to 55 lb / 25 kg, with an integrated rear brake light for practical cargo use.
  • Adjustable hydraulic suspension with lockout for rough roads and firmer pavement setup.
  • Hydraulic disc brakes with an electric motor cut-off sensor.
  • 1,600-lumen smart headlight with high/low beam and a dusk-to-dawn sensor.
  • Smart display and app with color LCD, RFID entry, and Bluetooth connectivity.
  • 330 lb / 150 kg total load rating for the rider and cargo combined.

The StormX is one of several FavoriteBikes models available through Costco Canada. If your ride is focused more on commuting than loose terrain, compare Costco electric bike models or read our Costco electric bike Canada buying guide before choosing.

StormX FAQ

Yes. The FavoriteBikes StormX is available through Costco Canada and directly from FavoriteBikes. Costco sets its own current price, delivery, availability, and checkout terms; direct orders use the current price and Add to cart option on this page. FavoriteBikes provides manuals, app support, and warranty service for both purchase paths.

The StormX is the all-terrain fat tire model, with 26 × 4-inch tires, adjustable hydraulic suspension, and a welded cargo rack. The Hybrid CSC is a low-step commuter. Read the StormX vs Hybrid CSC comparison, or compare Costco electric bike models across the lineup.

The StormX uses a removable 46.8V, 19.6Ah lithium-ion battery rated at 917Wh. It slides out of the frame so it can be charged indoors.

A full charge typically takes about 3–6 hours, depending on the starting battery level. Use the included Dpower charger and charge indoors as directed in the owner's manual.

The Canadian StormX configuration supports speeds up to 32 km/h. Ride within local rules and adjust speed for terrain, visibility, and conditions.

The 26 × 4-inch Wanda fat tires add traction and stability on loose, uneven surfaces, while the adjustable hydraulic suspension and 48V / 500W hub motor support rougher routes. Always adjust speed and braking distance for conditions and avoid heavy rain or immersion.

The package includes the StormX e-bike, Favorite Display, charger, platform pedals, two battery keys, RFID fob, Y-wrench, 15mm wrench, Allen wrench, reflectors, and owner's manual. Follow the manual for final setup before riding.

The StormX is rated for a combined rider-and-cargo load of up to 330 lb (150 kg). The welded rear rack can carry up to 55 lb (25 kg) of secured gear within that total limit.

The currently linked owner's manual lists 5 years for the frame, 2 years for the motor and electrical components, and 1 year for accessories and other essentials. Battery coverage is defined by the manual's charge-cycle terms. See the warranty terms for full eligibility and exclusions.

The StormX can handle everyday utility rides, but its main advantage is all-terrain traction and cargo capacity. For a lower-step, pavement-focused setup, compare it with the Hybrid CSC in the FavoriteBikes Costco Canada lineup.
