Battery Pack

Alta Motors Accu of batterij pakket

The Redshift owes its speed and endurance to the custom battery pack which powers it all. The Alta Pack crams 5.8 kWh into 30.8 kilos with a maximum of 350V: mile for mile, there is no smaller, more energy dense battery pack in transportation. Our battery team gave themselves three years to develop and commercialize wholly new technologies to achieve the performance and safety we demanded of an off-road race bike. The Alta Pack is waterproof - rated up to IP67. It is durable enough to handle impacts and vibrations up to 20G, and it is digitally self-monitoring. Our stacked, honeycomb architecture allows for extreme energy density at 185 watt hours per kilogram. This paired with a unique thermal wicking system to shed heat faster than any other lithium-ion transportation battery in production, gives the Redshift the edge you want on the track.

The Motor

Alta Motors Elektrische Motor

Alta’s water-cooled 14,000 RPM motor is pound for pound one of the most powerful in motorsports. It is optimized to the narrow width of the Redshift’s bulkhead and is precisely located at the roll center of the bike. This placement allows for the lowest polar moment of inertia in motorcycling - drastically minimizing any gyroscopic impediment to handling.The Redshift's motor weighs 15lbs and puts out 40hp and 36 ft-lbs of torque. The unit pushes power through a 3.5:1 gear reduction to deliver a 122 ft-lbs of torque at the counter shaft from a dead stop and 0 RPM.The Redshift delivers enough torque to lift the front wheel whenever you need to, and it corners like nothing you've ever ridden. The faster you go, the more of an advantage you have. And if you want to go fast, this motor will take you there.

The Bulkhead

Alta Motors 

The Redshift Bulkhead—the chassis core—functions as the outer motor casing, the cooling circuit for the motor and inverter, as well as the transmission case for the gear reduction. Additionally, it is the main structural hub, connecting to the rear suspension, the airframe, the forged monocoque chassis, and the trellis skidframe. All of this integration is coordinated with very specific strength, weight, and stiffness goals to produce the right ride and compliance characteristics at all lean angles, and under impact.

Alta Motors Frame of Chassis

Every component of the Redshift chassis and drivetrain is designed from the ground up by Alta's engineers to achieve maximum strength and efficiency per pound. By refining and combining off-the-shelf concepts, we increased the functionality of each element of our motorcycles and simultaneously reduced weight, build complexity, and potential for failures. These innovative designs give the Redshift the strength riders need with the speed and agility riders desire.

Power Management

Alta Motors RijderspositieAlta’s proprietary, water-cooled motor controller is a clean sheet design. Both the hardware and the software were developed in-house to integrate seamlessly with our high-speed, permanent-magnet, brushless motor. The controller transfers a direct, instant connection between the rider’s throttle hand and the rear tire. The relationship between the controller and the electric motor allows riders to tune their bikes' power to their riding conditions and riding style. Through pre-programmed throttle maps, riders can adjust the rate of acceleration and amount of engine braking to respond to changing conditions like hard-pack, turning to mud.

Suspension and Brakes

Alta Motors Voorwiel Detail

Where existing components meet our performance standards, we utilize the best that the motorcycle world has to offer. Brembo brakes and WP suspension with a rising-rate linked rear suspension means the bike is up for anything you can throw at it, and that spare parts and top notch tuners are readily available.

Alta Motors WP Achtervering


Alta engineers have re-imagined the ideal off-road subframe structure: strong, light, durable, and comfortable. Without a need to combat hot exhaust systems, the core of Alta's subframe could be made of Makroblend®, a resin engineered for exceptional durability. The Airframe allows the system to be compliant for rider comfort, and to bounce back rather than bend or break in a crash. To achieve a more efficient (i.e. lighter, stronger) structure, we designed a system of internal ribs and a stressed skin similar to that of an airplane fuselage. The Redshift Airframe performs with multiple times the strength of a standard aluminum or polymer subframe
