Alta Motors designs and manufactures the most advanced electric motorcycles in the world. What started as a “what-if?” between friends in 2010 has matured into a full scale Original Equipment Manufacturer (OEM). We endeavor to not only advance the field of motorcycle technology, but to also apply our technology and advanced engineering across transportation markets. In pursuit of this goal we have recruited an agile team of experts, developed innovative electric vehicle technology, and created a world class manufacturing operation headquartered in Brisbane, California.
This is where we’re building The Future of Fast.

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. 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. 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.
Alta’s liquid-cooled 14,000 RPM motor is pound for pound one of the most powerful in motorsports. The Redshift's motor weighs 15lbs and pushes power through a 3.5:1 gear reduction to deliver full 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.
Alta’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 relationship between the controller and the electric motor allows riders to tune their bikes' power to their riding conditions and riding style.
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. 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.
FRAME & SWINGARM
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.
