Alpha ST Electric Cruiser Bike

The Murf Alpha ST is a powerful step-through electric bike built for riders who want the speed and capability of a full-size fat-tire e-bike with a more accessible frame design. It can be configured as either a Class 2 or Class 3 e-bike, offering throttle assistance up to 20 mph and pedal assistance up to 28 mph in Class 3 mode. Five levels of pedal assist allow riders to control how much support the motor provides, while the single-speed drivetrain keeps operation simple and reduces maintenance.

A 750-watt motor gives the Alpha ST responsive acceleration and dependable climbing power. Its 52-volt, 20 amp-hour battery provides 1,040 watt-hours of capacity, supporting an estimated range of approximately 30 to 60 miles per charge. Actual range will vary depending on rider weight, terrain, speed, weather, and assist usage. The battery carries an IPX6 water-resistance rating, and the bike is compliant with UL 2849 and UL 2271 standards.

The Alpha ST rides on wide 26-inch by 4-inch fat tires for added traction, stability, and comfort. Four-piston hydraulic disc brakes provide strong stopping performance, while the threadless headset helps create a solid and responsive steering feel. The step-through frame makes mounting and dismounting easier, and the integrated rear rack adds practical carrying capacity for gear or accessories. An off-road-style headlight, integrated brake light, and tail light improve visibility in changing conditions. The Murf Alpha ST weighs approximately 70 pounds, supports up to 330 pounds of total weight, and is best suited for riders around 5 feet 7 inches to 6 feet 5 inches tall.
