The HXBike Shark Mako is a distinctive electric bike designed to stand out with its aggressive styling and powerful features. Marketed as a class 2 eBike, this model offers versatility through pedal assist and throttle options, making it suitable for various riding conditions. This review explores the Shark Mako’s specifications, performance on the road and off-road, battery life, and overall user experience.

Technical Specifications of the Shark Mako

The Shark Mako is equipped with a 48V 750W pseudo rear hub motor, capable of delivering a peak power output of 1500 watts and 85 newton-meters of torque. This configuration allows the bike to reach speeds up to 20 mph under class 2 settings. However, the bike can be unlocked to class 3, enabling speeds of up to 37 mph according to the manufacturer.

Battery and Charging

The battery is a 48V 20Ah pack, hidden discreetly within the down tube, offering a total power capacity of 936 Wh. Charging is facilitated by a 3-amp charger, which fully recharges the battery in approximately six hours. The battery can be removed for off-bike charging but requires several steps to unlock and extract, including moving the front tire and unscrewing a dial.

Drivetrain and Gearing

A Shimano 7-speed drivetrain with a Shimano derailleur and a seven-speed thumb shifter controls the bike’s gearing. The chainring size is 44 teeth, optimizing a balance between torque and speed. However, riders may experience “ghost pedaling” at low speeds due to the smaller chainring.

Brakes and Suspension

Stopping power is provided by Logan two-piston hydraulic brakes paired with 180 mm rotors. Front suspension consists of spring-loaded forks with 100 mm of travel, preload adjustment, and lockout functionality, which helps absorb shocks during rough terrain rides.

Tires and Frame

The bike features CST Patrol tires sized 27.5” x 2.25”, with an aggressive mountain bike tread pattern and puncture resistance. The frame accommodates riders between 5’5” and 6’3” (55 to 63 inches in inseam), with adjustable seat height ranging from 33” to 41”. Available in gray or blue, the Shark Mako weighs approximately 61.7 lbs and supports a maximum payload of 400 lbs.

Features and User Interface

The Shark Mako’s cockpit is designed with a motorcycle-style layout. On the left handlebar, riders find the rear brake lever, horn, headlight control, and a full-color display. The display shows battery percentage, speedometer, pedal assist levels (1-4), trip data, and odometer. The right handlebar hosts a full twist throttle, front brake lever, and gear shifter buttons.

Lighting and Safety

The bike includes an integrated headlight positioned below the front fender with a single bright bulb. Reflective gills and a lit-up “nose” add to the bike’s visibility and unique aesthetic. Plastic fenders on the front and rear help reduce dirt splatter during rides.

Durability and Certifications

The Shark Mako is in the process of obtaining UL2271 and UL2849 certifications, ensuring safety and reliability standards. It also has an IPX6 water resistance rating, protecting it against high-pressure water jets from any angle.

Performance Evaluation

In class 2 mode, the pedal assist caps speeds at around 15.5 mph, which the reviewer found somewhat limiting. However, throttle-only mode allows speeds reaching up to 32-33 mph, demonstrating the bike’s true potential for higher speed rides. A slight delay exists in pedal assist activation, requiring two to three pedal rotations before power engages.

Hill Climbing Capability

The Shark Mako struggles moderately on steep inclines, such as a 20° grade hill dubbed the “hill of pain.” Throttle-only mode provides enough power to ascend, albeit slowly. Pedal assist requires shifting between levels and gears to maintain momentum, with the highest assist levels sometimes not engaging power immediately. The rider’s effort remains significant during climbs.

Off-Road and Terrain Handling

Equipped with aggressive mountain bike tires and front suspension, the Shark Mako handles off-road conditions competently. The bike performed well on muddy trails and even managed to traverse sandy beach terrain, requiring moderate rider effort. Noise from rattling components was noticeable, especially on rough terrain, but did not detract significantly from the ride quality.

Battery Life and Range

The claimed range is up to 75 miles on a single charge, but real-world testing showed a 23.5-mile ride with 4% battery remaining after mixed use involving throttle and pedal assist. Battery indicator accuracy was high, closely matching GPS-measured distance. The bike’s power delivery remains consistent even at low battery levels, although a warning error appears early to alert riders.

Additional Observations and User Experience

The seat is firm but shaped ergonomically with a central comfort groove, suitable for longer rides. Pedals provide good grip, preventing foot slippage. The adjustable seat post and cockpit controls are user-friendly but may require some acclimation for first-time riders.

Noise and Build Quality

The bike produces noticeable rattling noises from the battery compartment and covering panels, especially on uneven surfaces. The front headlight occasionally contacts the front fender when riding over bumps, suggesting the front fender may need removal for aggressive off-road use.

Braking Performance

Hydraulic brakes deliver reliable stopping power with a stopping distance of approximately 17 feet from 15 mph and 53 feet from 28 mph. However, the aggressive tire tread may increase stopping distances due to sliding on dry surfaces.

Missing Features

The Shark Mako lacks a walk-assist feature, which some eBikes offer for ease of pushing the bike uphill or through tight spaces. The horn, while loud, may be too aggressive for trail etiquette, where a bell might be preferable.

Is the HXBike Shark Mako Worth It?

The HXBike Shark Mako stands out with its bold design, solid throttle performance, and competent off-road capability. While it excels in throttle-assisted speed and offers a comfortable ride with good battery life, there are limitations in pedal assist speed capping, hill climbing power, and some build quality concerns such as rattling and fender clearance.

This bike is ideal for riders who prioritize throttle control and want a unique-looking eBike for urban and moderate off-road riding. Those who prefer longer pedal assist speeds or require smoother hill climbing may find it less suitable.

For interested buyers, the Shark Mako is priced at $1,499 with a 2-year warranty and currently available with discount options. The bike’s distinct aesthetics and throttle responsiveness make it a compelling choice in the mid-range electric bike market.
