Further, the hardtail electric bike is equipped with a Shimano Deore drivetrain for smooth, accurate shifting using a wide range of gears. This means you can handle the added power of the pedal-assist providing a longer lifespan of the components.

The Suntour suspension fork is lightweight and plush while the 2.6-inch Schwalbe tires keep you on track. An added benefit is the tires are puncture-resistant to help minimize flats. Furthermore, it comprises a dual-layer skid plate that protects the motor from rock strikes.

Another standout is the Shimano 10-speed transmission with an 11-42T cassette offering you a gear for every situation you cycle. The hydraulic disc brake is powerful and keeps your speed in check for off-road cycling.

From the first pedal you take, the Cube 500 will help you get there. The motors slotted into a perfect position in the chassis and the batteries placed inside the cast down tube and looks great.

The fantastic thing is you do not need to remove the battery for charging.

Other Fantastic Features

The e-bike has a minimalist design, but loads of potential to upgrade. There is a bottle cage on the seat tube and has rack bosses on the seat. With the internally routed cables, they stay out of the way and make servicing easier.

The seat tube is pre-routed to use with a seat post dropper.

The majority of the bike component is black, including the lower fork, seat, handlebar, rims, stem, and seat post. The spokes, disc brake rotors and suspension fork look nice in the silver highlights. The fork has no anodized stanchions and is not adjustable but has a 15 mm thru axle with supported wider Boost hub spacing to use with a wide spoke bracing angle.

Cube Hybrid Pro 500 - BatteryIncluded you receive a Bosch 2 amp battery charger and is compatible to use with the 4 amp charger as well. The Performance Line motor produces faster energy and some reduction-gearing drag compared to an Active Line motor. With the engine, you get a higher torque of up to 75 nm with high-speed pedal support.

So if you do enjoy pedaling fast, the Performance Line CX motor will keep up and not fade out. What this means is that you don’t have to shift as frequently to maintain a higher speed.

The mountain electric bike has a Bosch motor controller that measures the rear wheel speed, pedal torque, and pedal cadence.

It also has a built-in sensor for shifting and reduces the pressure automatically when changing gears. The Shimano Deore drivetrain has a ten (10) speed system powered with a Shimano trigger shifter interface allowing you to pull in or push out for higher gears. With the Shadow Plus derailleur, it brings it closer to the wheel and avoids rock strikes.

The top speed reached by this ebike is 20 mph (32 km/h).
