Maximizing Performance: A Technical Breakdown of the Maui Jack Folding eBike

The Maui Jack Folding eBike is designed for riders who need power, convenience, and versatility in an electric bike. While its compact folding design makes it easy to store and transport, its performance-focused components make it an ideal choice for both urban commutes and light trail riding.

In this technical deep dive, we'll explore the key engineering aspects of the Maui Jack that set it apart—from its Bafang motor and Samsung battery to its drivetrain, braking system, and suspension setup.

Power & Efficiency: The Heart of the Maui Jack

500W Bafang Rear Hub Motor

The Maui Jack is powered by a 500W Bafang brushless rear hub motor, delivering smooth yet powerful assistance across various terrains. Here’s why this motor stands out:

• Consistent Power Output – A 500W rating provides enough torque to handle hills, city streets, and light off-road paths without struggling.
• Rear Hub Placement – With the motor integrated into the rear wheel, the bike benefits from better weight distribution and a direct power transfer to the road.
• Quiet & Efficient Operation – The brushless design reduces friction and noise, offering a smooth, silent ride.

5 Levels of Pedal Assist & On-Demand Throttle

The Maui Jack gives riders full control over how much assistance they want:

• Pedal Assist System (PAS) – A torque-emulating sensor delivers adjustable assistance across 5 levels, allowing for customized riding experiences.
• Thumb Throttle Control – Need an extra push? The on-demand throttle provides instant acceleration, great for starting from a stoplight or tackling a steep hill.

Speed & Range

• Top Speed: Up to 20 mph (depending on conditions and rider input).
• Range: 40-55 miles per charge, subject to rider weight, terrain, and assist level used.

Battery & Power System

Samsung 48V 15Ah Battery

The Maui Jack is equipped with a Samsung lithium battery that’s removable and securely locked inside the frame. This ensures safety while offering easy access for charging.

• High Capacity – With 15Ah (5000mAh capacity), the Jack can handle long-distance rides without frequent recharges.
• Smart Charging System – The 48V Smart Charger comes with LED status indicators and CE certification, ensuring safe and efficient charging.

Drivetrain & Gearing: Built for Adaptability

Shimano 7-Speed Drivetrain

The Maui Jack uses a Shimano Tourney 7-speed system, giving riders a range of gears to suit different riding conditions.

• Trigger Shifter – Allows for quick and precise gear changes, especially useful in stop-and-go city riding.
• 46T Crankset & 14-28T Cassette – The combination of crankset size and cassette gearing offers a balanced ride, letting you pedal efficiently even at higher speeds.
• KMC Z7 Chain – Known for its durability, this chain handles electric bike torque loads without excessive wear.

Stopping Power: Hydraulic Disc Brakes for Maximum Control

The Maui Jack is equipped with XD-E300 hydraulic disc brakes—a premium braking system that offers better control, stopping power, and reliability than traditional mechanical brakes.

• 160mm Rotors – Large rotors improve heat dissipation, preventing brake fade on long descents.
• Smooth Braking Feel – Unlike mechanical brakes, hydraulic brakes require less force, allowing for gradual, controlled stops.
• Safety in All Conditions – Whether it’s wet roads or steep downhills, the hydraulic system ensures consistent stopping power.

Frame & Suspension: Comfort and Durability

Alloy Folding Frame & Suspension Fork

The Maui Jack's alloy frame is designed for durability, portability, and performance.

• Lightweight Yet Sturdy – At 64 lbs, it’s built for strength without unnecessary bulk.
• Folding Mechanism – The folding stem, frame, and pedals make it compact and easy to transport.
• Guide 20 Suspension Fork – Helps absorb shocks from uneven terrain, making city commutes and light trail rides smoother.

Wide 4-Inch Fat Tires

• CST 20x4-inch tires provide excellent traction and a comfortable ride.
• Ideal for both pavement and gravel paths, giving riders versatility without compromising control.

Who is the Maui Jack Best For?

The Maui Jack is perfect for riders who need a folding eBike with power and comfort. It’s ideal for:

• City Commuters – A foldable frame, strong motor, and long battery life make it an excellent urban ride.
