Both the FavoriteBikes Hybrid CSC ST and StormX are available exclusively at Costco — but they're built for very different riders. The CSC ST is an urban commuter refined for paved roads and everyday convenience, while the StormX is a fat-tire powerhouse designed for off-road adventures, snow, sand, and riders who demand maximum range.

Hybrid CSC ST — The Urban Commuter
The Hybrid CSC ST is engineered for riders who spend most of their time on paved roads, bike lanes, and city streets. With 27.5" × 2.2" Kenda road tires, a lightweight step-through frame, and a Shimano Altus 9-speed drivetrain, it handles daily commutes with ease. The included pannier bag, fenders, rear rack, and rear light mean you can ride straight from the box — no accessories to hunt down.
The 48V 14Ah LG MJ1 battery (UL-rated) delivers up to 60 miles of range, and the Bafang motor's 60Nm torque handles moderate hills without breaking a sweat.
Choose the Hybrid CSC ST if you:
- Commute daily on paved roads, bike paths, or city streets
- Want a step-through frame that's easy to mount and dismount
- Prefer a lighter, nimbler bike for urban riding
- Value a complete out-of-the-box package (rack, fenders, bag)
- Need up to 60 miles of range for longer commutes
StormX — The All-Terrain Powerhouse
The StormX is built for riders who go beyond the pavement. Its 26" × 4.0" fat tires provide exceptional traction on snow, sand, gravel, and rough trails. The high-torque motor delivers up to 1200W peak power, and the massive 917Wh battery gives you up to 80 miles / 125km on a single charge — the longest range in the FavoriteBikes lineup.
The heavy-duty hydraulic suspension with lockout absorbs trail impacts, while the welded rear rack keeps your gear secure even on bumpy terrain.
Choose the StormX if you:
- Ride off-road, on trails, snow, sand, or gravel
- Want maximum range — up to 80 miles per charge
- Love the stability and grip of fat tires
- Need a bike that handles diverse terrain year-round
- Want raw peak power (1200W) for challenging climbs
