🐐 THE BILLY GOAT SL
Street-Legal Power. Fat-Tire Confidence. Everyday Freedom.
The Billy Goat SL brings a powerful 750W electric motor, 1,000W peak output, 70Nm of torque, and a UL 2271-certified 52V 20Ah Samsung battery into a street-oriented fat-tire e-bike built for commuting, neighborhood riding, recreation, and everyday adventure.
With 20 MPH throttle operation and up to 25 MPH pedal-assist speed, plus up to 35+ miles of electric range or 60+ miles with pedal assist, the Billy Goat SL gives you the flexibility to choose how you ride.
⚡ POWER THAT FEELS READY
🔋 750W Motor • 1,000W Peak
The Billy Goat SL uses a 750W motor with 1,000W peak output and 70Nm of torque.
That combination gives the bike strong low-speed pulling power and responsive acceleration for everyday riding and moderate hills.
🚀 Up to 25 MPH
-
Throttle: up to 20 MPH
-
Pedal assist: up to 25 MPH
-
Class: Class 2 throttle / Class 3 pedal assist configuration where applicable
The bike ships from the factory configured around its street-oriented Class 2/Class 3 setup. Local laws can vary, so riders are responsible for confirming the requirements where they ride.
🔋 52V 20Ah SAMSUNG BATTERY
The Billy Goat SL is equipped with a 52V 20Ah Samsung-cell battery with UL 2271 certification.
Range
Up to 35+ miles using electric power.
Up to 60+ miles using pedal assist.
Actual range varies with rider weight, terrain, temperature, speed, tire pressure, riding mode, wind, stops and other conditions.
🔌 Charging
The included charger is rated:
58.8V / 3A
Full charging time:
Approximately 6–7 hours
That makes overnight charging straightforward for regular commuting and recreational use.
🛞 FAT-TIRE CONTROL & STABILITY
The Billy Goat SL uses wide, puncture-resistant INNOVA tires designed to provide a substantial contact patch for everyday road riding and suitable unpaved surfaces.
Tire configuration
-
Front: 20 × 4.0
-
Rear: 20 × 4.5
The staggered tire sizing gives the bike a distinctive stance while helping provide stability and traction.
🛑 4-PISTON HYDRAULIC BRAKING
Stopping power comes from Karasawa 4-piston hydraulic disc brakes.
Hydraulic braking provides controlled lever feel and strong stopping performance, making it a particularly useful feature on a higher-powered fat-tire e-bike.
🛞 DURABLE MAG WHEELS
The Billy Goat SL uses durable mag wheels, giving the bike a clean, modern appearance without conventional spoke wheels.
Combined with the wide 20 × 4.0 front / 20 × 4.5 rear tires, the setup is designed around stability and everyday durability.
⚙️ SHIMANO 7-SPEED DRIVETRAIN
A Shimano 7-speed shifter gives riders additional gearing options when using pedal assist.
Use lower gearing for controlled climbing and higher gearing when you want to comfortably maintain speed on flatter roads.
💡 ROAD-READY EQUIPMENT
The Billy Goat SL isn't limited to motor and battery performance.
It comes equipped with:
💡 High / Low Beam Headlight
Switch between high and low beam lighting depending on riding conditions.
↔️ Front & Rear Turn Signals
Integrated turn signals provide additional visibility when changing direction.
📣 Horn
A built-in horn provides an audible warning option for traffic and pedestrians.
🔑 Throttle Ignition Key
Key-controlled ignition adds another layer of control when starting the bike.
🔒 Rear Wheel Lock
An integrated rear wheel lock provides an added security feature when parked.
📟 LCD Display
Monitor important riding information from the integrated LCD display.
📱 BIKEGO App Compatibility
The LCD system can work with the BIKEGO app, including optional navigation functionality.
🏙️ BUILT FOR REAL-WORLD RIDING
The Billy Goat SL is especially suited to riders who want one e-bike capable of handling multiple everyday roles.
🏠 Daily Commuting
The 750W motor, 70Nm torque, 7-speed drivetrain and fat tires give you a practical setup for everyday transportation.
⛰️ Hills
The 1,000W peak motor output and 70Nm torque provide strong assistance on moderate inclines.
Actual hill-climbing performance depends heavily on rider weight, grade, terrain, battery charge, temperature and riding conditions.
🛣️ Pavement
The 20 × 4.0 front and 20 × 4.5 rear tires provide a wide footprint and stable road feel.
🌲 Light Adventure
The wide INNOVA tires can provide additional traction and stability on suitable unpaved surfaces.
The Billy Goat SL is not specified by the manufacturer as a mountain bike or dedicated off-road bike, so demanding technical trails should be approached appropriately.
