No milestone event takes place in a vacuum, and…Alta was formed in 2010, just two years after the Tesla Roadster had been in production. They are…Marc Fenigstein, Derek Dorresteyn, Jeff Sand, and David Drennan. It was started by four friends that were all motocross enthusiasts. I’ll get back to that in just a few minutes… Where it beginsĪlta started out as a company in October of 2010, located in the southern part of the San Francisco Bay with the name “BRD”. One of the things that distinguish the Alta design is the advanced liquid-cooled motor, which helps it manage heat-spikes from rapid-fire acceleration cycles. The rapid-fire speeding up and slowing down on dirt bikes is hard on the motors, controllers, and batteries, so…if someone is making an electric dirt bike that does this well, then…the engineers at that company are doing something right. And once you get on the main highway? you could cruise for as much as an hour without needing to stop and then accelerate up to cruise again.Ĭompare that to dirt bikes. This is where we’re building The Future of Fast.As a comparison, street motorcycles accelerate hard after the light turns green, but…then they enter a cruise-phase that can last for over 90% of the time they are running up to the next red light. 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. We endeavor to not only advance the field of motorcycle technology, but to also apply our technology and advanced engineering across transportation markets. What started as a “what-if?” between friends in 2010 has matured into a full scale Original Equipment Manufacturer (OEM). *** Estimation based on continuous riding under moderate usageĪlta Motors designs and manufactures the most advanced electric motorcycles in the world. * Torque measured at Countershaft Sprocket REAR BRAKE: Brembo Single Piston 219mm Rotor RECHARGE TIME: 2.5 hrs(240v)| 4 hrs(120v)įRONT BRAKE: Brembo Two Piston 260mm Rotor 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. Additionally, it is the main structural hub, connecting to the rear suspension, the airframe, the forged monocoque chassis, and the trellis skidframe. 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. 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’s motor weighs 15lbs and puts out 40hp and 36 ft-lbs of torque. This placement allows for the lowest polar moment of inertia in motorcycling – drastically minimizing any gyroscopic impediment to handling. It is optimized to the narrow width of the Redshift’s bulkhead and is precisely located at the roll center of the bike. Our stacked honeycomb architecture allows for extreme energy density at 185 watt hours per kilogram, combined with a unique thermal wicking system to shed heat faster than any other lithium-ion transportation battery in production.Īlta’s water-cooled 14,000 RPM motor is pound for pound one of the most powerful in motorsports. The Alta Pack is waterproof rated up to IP67, is durable enough to handle shocks and vibes up to 20G, and is digitally self-monitoring. Mile for mile, there is no smaller, more compact, energy dense battery pack in transportation. The combination of low weight and lightning fast acceleration make for a potent street-legal motorcycle that gives you all the tools necessary to experience the offroad world in the purest manner possible. Built with the DNA of a motocross bike, our Redshift EX eliminates the incessant oil changes and maintenance intervals of its high-strung competitors, and still slays on the trail. The 2018 Redshift EX is the ideal ratio of motocross speed, singletrack prowess, and urban capability.
