OVERVIEW
The Doohan iTank is being exclusively distributed by Motorino in Canada. It is the first electric crossover motorcycle in the world in its class. It is built on a tri-split chassis incorporating a unique two-wheel front end. Each of the two wheels has an independent hydraulic suspension system. The unique three-wheel design of this bike produces exceptional stability and safety when compared to two-wheel motorcycles. This bike is designed by a team of engineers who have implemented the latest innovations of the electric vehicle industry and is built using the highest quality materials and components available. The iTank has the precision of a Swiss watch without any of the delicacy, an image that immediately comes to mind upon embarking on a ride. This bike performs just as well on pavement as on the road, giving you the confidence to take corners sharply. No matter what the roughness of the road, the independent adjustment of each wheel to the surfaces of the road will ensure the utmost stability.

BATTERY
The battery pack is composed of the highest energy density Panasonic or LG 18650 battery cells. The battery pack utilizes the technological innovations of Tesla to provide control over each individual battery cell compared to the dated cluster control of a regular Lithium-Ion battery pack. This technology eliminates the need to compromise on the capacity or cycle life of battery cells for the sake of the battery pack as a whole. The battery management system (BMS) is developed by the French company FPS (Forsee Power Solutions). The BMS precisely monitors temperature, overcurrent draw, over-charge, over-discharge, prevents short circuits, and constantly equalizes capacity in each cell. FSP have developed packaging that reinforces each cell against any physical impact. The casing is also waterproof and provides efficient heat dissipation for each cell. The BMS communicates with the VCU (Vehicle communication Unit) through the CANBUS protocol and reports current consumption and generated current levels when using the brakes. The state of Charge (SOC) is dynamically calculated and displayed as a percentage on your dashboard. An iOS and Android application is currently in development that will be able to communicate through a wireless network with the on-board VCU.

There are two battery compartments that can accommodate two removable 60V/26AH Lithium batteries. The two batteries are connected in parallel and the VCU communicates with each one individually. The HS(High Speed) version of iTank provides a range of 75km, with speed of 65km/h. On ECO mode, the range is 95km, with a maximum speed of 45km/h.

The batteries can be charged through a single CANBUS port inside the bike or removed and charged off the bike.

MOTOR
The 12” QS motor is incorporated in the cast aluminum rear wheel rim. It is rated as a 1490W continuous power motor but delivers 3600W peak power. All of this is possible at a torque of 150NM and it does not even produce any excess heat! The high efficiency of the motor means that it can roll down to 900W on a flat surface—while maintaining the highest speed—thus ensuring low power consumption and an even longer range.

The most reliable indicator of motor efficiency is the relation between power and torque at every speed. The iTank delivers 100NM torque at 420RPM at a continuous power of 1490W with 80% efficiency. Translated, this means that the bike can handle a 22% incline hill with 40km/h speed when only 22Amps are drawn from the battery. This is only 40% of the total peak power this motor can deliver. This means that there is an additional 50NM of power remaining!

CONTROLLER
Another advanced and unique feature of the iTank is the controller of the motor. Firstly, the bike is equipped with a FOC (Field Oriented Controller) based on a vector control algorithm with a sinusoidal output signal. The whole concept of the traditional “impulse style” Hall Effect throttle has been changed in the iTank to a hard steel cable throttle ensuring accelerating stability, response and safety. This type of controller is designed using the established principles of acceleration in electric cars. The controller eliminates the disproportional starting part of the acceleration curve and ensures smooth yet powerful acceleration. It also relieves the battery of any initial high-power demand that can be extremely detrimental to the life of the battery.

The controller is also connected to the VCU through the CANBUS protocol connection. The controller uses this connection to report to the VCU any malfunctions of the motor-control system or any deviation from the expected behaviour.

CHASSIS
The uniqueness of the DOOHAN iTank begins with the chassis. It is built on a tri-split concept using a hard carbon-steel midsection holding together the aluminum alloy front end and suspension together with the aluminum alloy rear fork. Elegant platform style foot rests for the rider and passenger are stretched at the bottom at each side. They are made out of hard aluminum alloy and are part of the structural integrity of the body. The chassis also features an aesthetic and spacious seat on top. The midsection of the frame accommodates two battery compartments, thus ensuring that their weight is close to the ground. The rear shock is concealed in a horizontal position. All aluminum and steel frames are robot welded. Finally, the frame is powder painted, thus protecting the frame from corrosion.

SUSPENSION
The front suspension is the most distinguishable part of this bike. The arms are built with the hardest aluminum composite alloy available. They are braced against the robust mid section with their ends freely floating in orthogonal directions. A rocker bracing is incorporated on top of the arms translating the vertical movement of the wheels into horizontal movement of the DOOHAN iTank.  Bilateral spring-loaded shock absorber (not in the picture) keep both wheels in parallel and ensure the smooth tilting of the suspension. The spring provides resistance against sharp angled tilts, acting as a counter-force to the weight of the rider. Twelve SKF bearings support each end of the arms. All bushings and bolts are made from hardened steel with titanium coating preventing metal deformation even under the most violent conditions. Two vertical hydraulic absorbers at each end prevent the shocks from hammering at extreme conditions. All connection points are covered with dust-protective rubber membranes.

The rear suspension is also unique. The spring-loaded shock absorber is elegantly concealed in the mid-section of the bike and a flexible rubber dust cup covers it outside preventing any dirt penetration. A rocker arm is also used to convert the vertical movement into horizontal motion, ensuring a longer travel of hydraulic piston. That wouldn’t be possible using ordinary vertical shock absorbers.

All three touch points provide incredible stability and a comfortable ride in all terrain conditions. When used on rough surfaces each of the front wheels adjusts itself to the terrain and as a result the front end vertical amplitude is twice reduced. Each wheel has a drop of 18.3 cm which makes it possible to overcome obstacles such as curbs, stairs, ditches, etc. The long traveling arm of the rear suspension also allows the rear wheel to follow the terrain surface smoothly.

BRAKES and SAFETY features
Unlike a two-wheel cycle, the iTank is equipped with three hydraulic disk brakes. For a typical two-wheeled vehicle, the front wheel is responsible for 80% of the braking power. As the iTank has two front wheels paired to 220mm front disk brakes, it can provide twice the braking power of any two-wheel vehicle. The braking power is not only improved by the double hydraulic disk at the two front wheels but by the larger footprint at the front. All two wheel cycles are vulnerable to jackknifing on slippery conditions but the two front wheels of the iTank ensure vehicle-like braking performance and keep the scooter straight when immediate braking is required. The iTank controller also provides very efficient regenerative braking in the rear wheel before the mechanical brakes are activated. In wet or otherwise slippery conditions, the regenerative brake acts as an Anti Block System (ABS).

The three ground touch points make the iTank a much safer ride compared to any two-wheel motorcycle. More than 80% of motorcycle accidents occur without the involvement of any other vehicles. They occur because of sideslips due to sand or rocks on the road or because the rider underestimated the tilting angle. The two wheels on the front not only provide a better foot-print but also eliminate the inherent front wheel danger of a typical motorcycle. The tilting angle is also restricted to 40 degrees which gives the rider the confidence to counter the centrifugal force when performing sharp turns.

LIGHTS

The headlight incorporates automotive standard hi/low beam LED lights that provide brighter and wider illumination than the equivalent capabilities of a halogen headlight at 60% less power consumption. Over 8000 lumens are concentrated in a 35 degree beam on high beam mode. Independent LEDs support the wide angle daylight running lights. The rear running and brake LED lights are wrapped around the rear end providing 270 degrees of visibility.

The front and rear LED turn signals are 40cm apart from each other thus ensuring that the iTank conforms to motorcycle regulations. They are designed to be visible from the side as well.

DISPLAY, GAUGES, SWITCHES

An extra wide and bright dashboard displays the current speed and error codes, total mileage, controller temperature, real time output current, battery charge, the current consumption and regeneration current.

The electronic gear switch, the hi/low beam headlight switch, and the motor kill switch are ergonomically positioned on the right-side handle bar.

SECURITY
The DOOHAN iTank is equipped with mechanical and electronic theft protection devices. When the key is inserted in the ignition, pressed and turned left the handlebar will be locked. The bike is equipped with network enabled GPS tracking which communicates with the smart phone application. Thus the bike can be located from anywhere in the world. The application will be released in June of next year. The bike can also be locked and unlocked remotely using the application.

VEHICLE COMMUNICATION UNIT (VCU)
The DOOHAN iTank is equipped with a Vehicle Communication Unit (VCU) that communicates with all of the electronic components of the bike. The VCU runs diagnostic tests on each of the components every time it is activated to ensure the utmost in safety and security. The VCU communicates with all other electronic components of the bike through the CANBUS protocol. If a component is malfunctioning the VCU displays the error code for the problem on the dashboard. The GPS module, the security and communication modules are all incorporated into the VCU. It automatically sends messages to the application when the position of the bike is changed, when an error is reported or when the battery is at a critical level.

ACCESSORIES
Specially designed a cargo travel pack make the DOOHAN iTank as practical as a car three boxes – 2 on side and one on top are attached on to the back without interfering to the passenger seat. With a total volume of 120 litters they can accommodate as much language as a big suitcase and are secured with a lock. The top box is attached with a quick release mechanism and can be removed at any time.

At 70km/h you can consider a windshield for a rainy weather. It can be easily mounted and detached at any time.

A rain cover keeps your DOOHAN iTank dry on rainy days.

For extra security, you can lock the rear disk with alarmed disk brake lock.
