Brief Introduction – Dual Motor Electric Bike
What is a Dual Motor Electric Bike?
How does an Ebike Dual Motor drive bike handle?
Dual Motor Electric Bike can automatically change gears by the motor controller according to the size of the load, and adopts a scientific and reasonable method to solve the technical problems that the speed and climbing ability of ordinary single-speed motors cannot be balanced and contradictory. Double-drive electric vehicles can effectively improve the performance of electric bicycles.
All-wheel drive and its wide wheels would be ideal for riding on snow or beach sand.
The speed is limited to 45 kilometers per hour with the 2000W motors, and we can remove this limitation to reach up to 55 kilometers per hour with full throttle.
When going uphill, the dual-drive motors share the load of the electric bike, and the operating point of each motor is still near the maximum efficiency point of the motor’s output characteristics. For example, the motor still has 80% efficiency, and the current of the two motors does not increase (the consumption of the current may not be as much as 1 motor), but double the torque (the sum of the normal torque output of 2 motors).
Therefore, ebikes with dual drive motors should automatically achieve power matching according to road conditions, loads, and slope systems. The smooth road is driven by one motor, and the uphill and heavy loads (or overtaking) are automatically switched to 2 motors to drive synchronously; only dual-drive electric vehicles can obtain the best performance.
Secutronic KD800 Dual Motor Fat Tire Electric Bike：
This is a Dual Motor EBike, a double drive ebike with the main characteristic of having an electric motor in each of its wheels, being one of the few 2×2 all-wheel drive bicycles on the market.
The KD800 is a 2 wheel drive electric bike ideal for towing a trailer with the kids.
Its Aluminum Alloy Frame and Alloy Crown Suspension Fork with 120 mm of travel stands out for housing gigantic 26 inch diameter Fatbike wheels with 4″ thick Kenda K-Shiel tires and an anti-puncture system.
The design allows it to pose a very peculiar frame geometry, with the rear section, which forms the vertical bar and the structure of tubes that support the rear wheel, very sloping compared to the rear.
Front Fork and Front Wheel Drive: This setup is meant to give the rider room to jump out of the saddle quickly , and it is very similar to what downhill bikes offer, for precisely that reason.
Two electric motors KD800, double motors, one on each wheel
Particularly noteworthy are the two electric hub motors that are integrated into each of the wheel hubs, which, thanks to an energy management system that removes the power from the slipping wheel, sending more torque to the one with traction. They allow you to traverse virtually any terrain without flinching.
In each wheel axle, in the hub, it incorporates a 1000W motor (Ariel Rider Dual 750W motor), achieving a total power of 2000W in AWD 2×2 (All Wheel Drive) mode.
However, the KD800 isn’t exactly a downhill bike. The suspension system is only at the front, where it mounts an Alloy Crown Suspension Fork with 120 mm of travel, while at the rear it is rigid, that is, it does not include any type of shock absorber or swingarm to absorb irregularities.
This feature is not due to an oversight by the manufacturer or an attempt to reduce costs. The reason is precisely its double traction system. With the hub motor at the rear wheel, the suspension would be an inefficient part as it would require energy to compress with each run, which would reduce engine performance and thus lose traction.
To somewhat reduce the effect of eliminating this suspension, the frame is mounted on two tires with a very high four-inch ball, which eliminate a good part of the vibrations and make the slightest irregularities in the terrain imperceptible. Against it, the high rebound it offers when descending can be a problem.
KD800 Dual Motor Electric Bike Battery and Range
As for its electric traction system, it is with a single battery (not dual batteries) that works at 48 V and 17.5 Ah (840 Wh). And feed two 1000 Watt electric motors, each located in the wheel hubs. The pure power mode gets 50 kilometers of distance, a range that almost doubles to 100 kilometers with the pedal assist mode.
Double electric hub motor:
The two electric hub motors located in the hubs of both wheels of the KD800 are managed by a drive system that sends power to the wheel with the most grip.
The KD800 uses a transmission system that drives both wheels governed by a traction control system that sends power to the motor of the wheel whose tire has grip, removing it from the spinning wheel.
Advantages of KD800 Dual Motor Electric Bike
As for the benefits it can offer, KD800 ensures that it is capable of assisting the cyclist’s pedaling up to 45 km/h. Despite its frame, which aesthetically mimics downhill bikes. KD800 does not offer this model for excessively steep terrain, but it does offer it for roads and trails full of sand, gravel, mud or snow, no matter how steep they are.
The new gear drivetrain, derailleurs and shifters are provided by Shimano, while the rest of the components such as the handlebars, stem, saddle and even the seatpost have been developed in-house by Secutronic.
Currently, this electric bike is street legal in the U.S., considered an e-bike, and sells for $1,099 only.
