The Macfox X1S x Bs.zay Electric Bike combines distinctive co-branded styling with practical urban performance, comfortable fat tires, and dependable electric assistance. Built on the popular X1S commuter platform, this limited-edition model features an exclusive pearl-white frame with purple accents, giving it a unique appearance while retaining the everyday reliability of the original Macfox X1S. Powered by a 500W brushless rear-hub motor that reaches up to 750W at peak output, the X1S x Bs.zay delivers smooth acceleration and a manufacturer-rated top speed of up to 20 mph. Its removable 48V 10.4Ah battery offers up to approximately 28 miles of riding range with one battery, while an optional dual-battery configuration can extend the maximum claimed range to approximately 56 miles. Wide 20 × 4-inch tires, front suspension, hydraulic disc brakes, an extended cushioned seat, and a simple single-speed drivetrain make this electric bike suitable for daily commuting, campus travel, neighborhood riding, and relaxed weekend trips. Exclusive Bs.zay Co-Branded Design The X1S x Bs.zay stands out with an exclusive pearl-white finish complemented by purple details and coordinated graphics. The high-strength carbon-steel frame uses a pearl-powder finish designed to create a subtle shimmer under changing light. In addition to its unique appearance, the finish is intended to provide resistance against everyday scratches and paint chipping. The result is a distinctive moped-inspired electric bike that combines street-ready styling with a strong and practical frame. 750W Peak Motor Performance The bike is powered by a 500W rated brushless rear-hub motor capable of producing up to 750W of peak power. This provides responsive assistance when accelerating from a stop, navigating city streets, or riding on moderate inclines. The rear-hub configuration delivers power directly to the rear wheel, helping create predictable acceleration and a stable riding feel. Riders can use pedal assistance to reduce physical effort or engage the thumb throttle where permitted by local electric-bike regulations. The manufacturer lists the X1S x Bs.zay as a Class 2 electric bike with a maximum assisted speed of 20 mph. 48V 10.4Ah Removable Battery A removable 48V 10.4Ah lithium-ion battery supplies approximately 500Wh of energy capacity. It can be charged while installed on the bike or removed for convenient indoor charging. The removable design is useful for riders who park the bike in a garage, shared storage area, apartment building, or location without a nearby electrical outlet. A locking mechanism helps keep the battery secured to the frame during normal operation. Charging the standard battery takes approximately five to six hours under typical conditions. Up to 28 Miles of Standard Range With one fully charged battery, the Macfox X1S x Bs.zay provides a manufacturer-rated range of up to approximately 28 miles under standard testing conditions. Macfox states that its testing assumes an average rider weight and steady cruising in a moderate assistance setting. Actual range can vary depending on rider weight, terrain, speed, assistance level, throttle use, wind, temperature, tire pressure, and battery condition. Optional Dual-Battery Range Riders who require additional distance can install an optional second-battery setup. With two compatible batteries, Macfox lists a combined maximum range of up to approximately 56 miles. The dual-battery arrangement is especially useful for longer commutes and full-day recreational rides where charging opportunities may be limited. The additional battery is generally sold separately unless specifically included in the selected product configuration. 20 × 4-Inch Fat Tires Wide 20 × 4-inch tires provide a broad contact patch for improved traction and stability. Their added volume helps absorb smaller road imperfections and reduces vibration when travelling over cracked pavement, gravel paths, compact dirt, and other suitable surfaces. The fat-tire design also contributes to the bike’s moped-inspired appearance and low, stable riding stance. Riders should inspect tire pressure and tread condition regularly to maintain safe handling, efficient battery use, and predictable braking. Adjustable Front Suspension The front suspension fork helps absorb impacts from uneven pavement, shallow potholes, gravel, and other everyday surface irregularities. Macfox describes the suspension fork as adjustable, allowing the rider to tune compression and rebound characteristics for improved comfort and control. The rear section does not use a full-suspension system, so most shock absorption comes from the front fork, wide tires, and extended cushioned seat. Hydraulic Disc Brakes The X1S x Bs.zay is equipped with front and rear hydraulic disc brakes. Hydraulic braking provides a smooth and responsive lever feel while requiring less hand effort than many basic mechanical brake systems. A motor power-cutoff function disengages motor assistance when the brakes are applied, helping the rider slow down with greater control. Hydraulic brakes should be inspected periodically for pad wear, rotor alignment, fluid condition, and consistent lever pressure. Thumb Throttle and Pedal Assistance The bike supports both pedal assistance and thumb-throttle operation. Pedal-Assist Mode The motor provides assistance while the rider pedals. This mode can reduce effort during commuting and generally provides better battery efficiency than continuous throttle use. Thumb-Throttle Mode The thumb throttle activates motor assistance without requiring continuous pedaling. Availability and permitted operation of the throttle depend on local electric-bike laws and riding-area rules. Traditional Pedaling The bike can also be pedaled without electric assistance when desired or when battery power is unavailable. Single-Speed Drivetrain A simple single-speed drivetrain reduces shifting complexity and routine adjustment requirements. Instead of selecting between multiple mechanical gears, riders control effort and speed through pedaling, electric assistance levels, and throttle input. This straightforward arrangement suits flat or moderately varied urban routes where simplicity and low maintenance are priorities. Extended Comfort Seat The long moped-style seat provides a broad and cushioned seating surface for relaxed urban riding. Its low-profile design supports an upright riding position and contributes to the bike’s distinctive motorcycle-inspired appearance. The manufacturer recommends this model for riders approximately 5 feet 3 inches and taller. The seat and mounting hardware should be checked regularly to ensure all fasteners remain properly tightened. Backlit LCD Display A handlebar-mounted LCD screen keeps essential riding information visible while the bike is operating. The display shows key details such as: Current speed Remaining battery level Assistance setting Trip information System status The backlit design improves readability in changing lighting conditions, while handlebar-mounted controls allow assistance settings to be adjusted without unnecessary distraction. Integrated Front Lighting The bike includes an integrated front light designed to improve visibility during early-morning, evening, and low-light rides. Lighting helps make the rider more visible, but it should be used alongside reflective clothing and careful riding. Riders should also consider adding an appropriate rear light or additional visibility equipment when local rules require it. High-Strength Carbon-Steel Frame The frame is manufactured from high-strength carbon steel, providing a durable foundation for daily transportation. The fixed-frame construction avoids the hinge used on folding bikes, helping maintain structural rigidity. Macfox lists the complete bike weight at approximately 65 lbs and the recommended maximum rider load at approximately 220 lbs. The maximum load should include the rider and all carried accessories or cargo. Practical Urban Dimensions The compact 20-inch wheel platform creates a lower center of gravity than many full-size bicycles. This can make the bike feel stable during starts, stops, and lower-speed maneuvering. The published overall dimensions are approximately 71 × 27 × 42 inches, with a seat height of approximately 33 inches. Riders should compare these measurements with their height and preferred riding position before purchasing.
