Fat-tire e-bikes have quietly become one of the most-searched categories at Costco Canada — and for good reason. Wide tires, powerful motors, and all-terrain capability give riders the confidence to keep riding when the weather turns and the roads get rough.

The FavoriteBikes StormX ST sits at the center of that demand. Designed in Canada and available at Costco, it brings together fat-tire performance, a smart app ecosystem, and a feature set that punches well above its price.

This guide breaks down the StormX ST's fat-tire advantages, app capabilities, and exactly which types of riders it fits best.

Why Fat Tires Make a Difference

More Grip, More Stability

The StormX ST rolls on 26 × 4-inch fat tires — roughly twice the width of a standard commuter tire. That extra contact patch delivers immediate benefits: better traction on loose gravel, wet pavement, packed snow, and sandy trails. For Canadian riders dealing with seasonal road conditions, this isn't a luxury — it's practical.

A Smoother Ride Without Sacrificing Speed

Fat tires act as natural suspension, absorbing vibration from cracked pavement and uneven terrain. The StormX ST pairs this with a hydraulic front suspension fork rated for fat-tire geometry, giving you a genuinely plush ride. Most riders report it handles city streets and light trails equally well.

Built for Winter, Ready for Summer

Designed through a collaboration between Canadian Costco product specialists and the FavoriteBikes engineering team, the StormX ST was built from the ground up for four-season riding. The frame geometry, tire clearance, and motor tuning all reflect input from riders who need their e-bike to work on icy February mornings — not just dry September afternoons.

StormX ST Specs That Matter

Motor and Power

The StormX ST is powered by a 500W hub motor with a 1,200W peak output and up to 60 Nm of torque. It handles steep hills without hesitation, and maintains speed through sand or snow where cheaper motors bog down.

Battery and Range

The 20 Ah UL-certified battery (approximately 917 Wh) delivers up to 80 miles / 125 km of range on a single charge under optimal conditions. Even in higher assist modes, most riders comfortably reach 60–80 km per charge.

Integrated Rear Rack

Unlike bolt-on alternatives that flex under load, the StormX ST's rear rack is welded directly into the frame. It offers multiple mount points for panniers, cargo baskets, and accessories — making it a credible option for grocery runs, commuting with gear, or carrying hunting and camping equipment.

Favorite Smart System: What the App Actually Does

Full-Color LCD Display

The StormX ST ships with the Favorite Smart Display — a full-color LCD that shows speed, battery level, remaining range, assist level, and real-time diagnostics. Compared to the monochrome displays common on bikes in this price range, the difference in readability is noticeable, especially in sunlight.

Favorite App Features

Pair your StormX ST with the Favorite App via Bluetooth for a level of control that most Costco e-bikes don't offer:

• • Smart Lock / Unlock — lock and unlock your bike from your phone, with alarm alerts if the bike is disturbed
  • Ride Stats — track distance, speed, calories, and trip history
  • Assist Customization — fine-tune each of the 5 pedal-assist levels to match your preferred feel
  • Navigation — basic turn-by-turn directions displayed on the bike's screen
  • Firmware Updates — receive motor and display updates over the air

Adaptive 1,600-Lumen Headlight

The Cree 1,600-lumen headlight adjusts brightness based on ambient conditions — bright enough for unlit rural paths, auto-dimming in well-lit areas. It's integrated into the frame and powered by the main battery, so there are no AA batteries to replace.

Intelligent Lock

The Favorite Smart Lock activates automatically when you power down the display, immobilizing the rear wheel. You can also trigger it manually via the app — a genuinely useful theft deterrent for urban commuters.

Who the StormX ST Is Built For

The All-Weather Commuter

If you commute year-round in Canada and don't want to stop riding when it snows, the StormX ST is one of the few bikes at Costco's price point genuinely designed for that. The fat tires, powerful motor, and long battery range make cold-weather commuting practical rather than heroic.

The Adventure Rider

Heading out on mixed terrain — gravel paths, forest trails, beach rides, or hunting access roads — the StormX ST's fat tires and torque output handle surfaces that would stop a standard commuter bike. It's not a full mountain bike, but it comfortably bridges the gap between road and light trail.

The Cargo-Conscious Buyer

The welded rear rack and app-controlled smart lock make the StormX ST a practical daily hauler. Add a pannier set and you've got a cargo-capable commuter that doesn't look like one.

The Tech-Curious Rider

If you've looked at other Costco e-bikes and felt underwhelmed by the basic displays and no-app experience, the StormX ST's full app integration, adaptive lighting, and OTA updates offer a noticeably more modern ownership experience.

Who It May Not Suit

The StormX ST's fat tires add rolling resistance on smooth pavement. If you ride exclusively on flat, dry city roads and prioritize maximum speed efficiency, a lighter commuter bike like the Hybrid CSC ST may be a better fit. Fat-tire bikes also weigh more, which matters if you regularly carry your bike up stairs.
