Design Features





Built around a 1200cc BMW transverse flat 4 cylinder all-alloy engine, the Exodus is a transportation "Ultra-Machine." Brutally efficient in design and operation, this machine, clean, raw, sleek, and muscular, breaks tradition with its novel recumbent design. The Exodus is created from forged, cast, machined, and hand-formed aluminum; high-strength speciality steel tubing; magnesium castings; titanium machined parts; and turned, hammered, and woven stainless steel; metals that come together as an integrated whole through careful hand-welding and assembly. The beauty of the dull sheen of raw metal appeals to both the heart and mind of the rider. The Exodus is an ICBM - an Intercontinental Ballistic Motorcycle.

The Exodus is a nearly perfect "naked bike", you can see its essential mechanical components, including the engine, drive train, and many of its secondary systems, standing proudly exposed, nothing unessential stands in the way of them fulfilling their mechanical purpose.




Looking at the Exodus from the point of view of another driver watching it quickly approach in his rear view mirror, you can see how low and narrow it is - 43.5" high and 24" wide. The Exodus has about 50% less frontal area than a typical cycle of the same caliber. While completely surrounding the rider, the low and streamlined Exodus has quite low wind resistance, it leaps ahead of the competition when accelerating from 60-140MPH, where air resistance slows down other machines with similar power-to-weight ratios. Additionally, the low position of the rider, engine, and gas tank provide a center-of-gravity nearly a foot lower than contemporary motorcycles, enhancing the stability and maneuverabilty of the Exodus in a way not seen before in a street cycle.

In addition, many of its features deserve attention in their own right.

The front windscreen, little more than a simple lightweight single piece of Perspex, provides exceptional aerodynamics, exhibiting nearly the same effect as a full body fairing. The winglets, running the full length of the windscreen, further improve air flow and reduce drag. While the rider is nicely protected from the wind, he still remains open to world.



The rear driveshaft/swing arm and monoshock stand proud of the main chassis and exemplify the lean character of the Exodus. They evince a sense of purposeful, powerful, muscularity, the rear leg of a cheetah with claws gripping the earth. The rear fender is attached to the swingarm and follows the motion of the wheel, maintaining minimum clearance between the wheel and fender to accentuate aerodynamic air flow. As the Exodus moves down the road, the swing arm, far aft of the center of gravity, nicely absorbs bumps without affecting the composure of the main chassis, and provides controllable and predictable power delivery.



A 17" BMW alloy wheel is mounted to this swingarm, with stopping power provided by an 11.2" floating solid Brembo rotor clamped by a dual piston Brembo caliper. All wear items, including pads, filters, cables, electronics, and fluids, are stock BMW items to ease maintenance.

The exposed all-alloy BMW engine with magnesium covers is a work of art in itself. It's protected during a collision or roll-over by a horizontal element of the exo-skeleton which easily can be removed when the engine needs to be accessed for service. This engine, while providing exceptional high specific output, is extraordinarily durable and reliable, known to live up to the demands of hard autobahn use without a whimper. It feels like a turbine, it revs smoothly and easily, yet it has a nice exhaust burble at idle that turns into a wail as it approaches its 8500rpm red line.




The foot pegs and controls are designed with the same engineering principles in mind, they're cylinders of raw alloy, strength, and elemental functionality. Both the pegs and controls are made of lightened billet aluminum, very strong and rigid, perfectly positioned for riding control and comfort. They accentuate the essential metallic toughness of the Exodus and provide additional protection for the rider. A protective steel skidplate runs from near the front forks towards the rear beneath the rider and gas tank, shielding both from road debris and other dangers.

The front forks and wheel demonstrate more of the immense capabilities of the Exodus, with 12.5" dual Brembo cross-drilled floating rotors that will bring you down from 155MPH without too much drama, yet let you drive easily and smoothly at low speeds. Plus, the advanced BMW integrated hydraulic ABS couples the braking of the front and rear wheels for even better balanced behavior. The handling capabilities of the Exodus offer exciting new possibilities for both the street and track rider.




The alloy forks by Brembo are similar to conventional telescopic forks. However, these forks are shorter than those found on a typical motorcycle. They have been engineered to provide the rigidity and the specific rebound and damping rates required for the superior handling of the Exodus. A 17" BMW alloy wheel is mounted to these forks and shod with a high performance Metzler tire, suited for high speed in both the dry and wet, while providing excellent grip in the corners.

The bucket seat is a 20 degree inclined racing seat of perforated and hand-welded aluminum, specially constructed for lightness and strength; mimimum padding provides sufficient comfort while not reducing the connection of the rider with the machine. Ensconced in that seat, the rider feels as if he's strapped an engine on his back, like a pilot in a small jet. Behind the seat, the stainless steel mesh grill of the rear body shell serves as a massive air intake and provides excellent airflow to both the radiators and the engine intake.

The hand-formed aluminum rear body shell provides near perfect aerodynamics. The basic "tear drop" shape causes little turbulence or drag. As the stainless steel mesh intake grill provides air to both the engine intake and radiators, the body shell then permits hot air from the radiators to escape through additional stainless steel mesh grills, a pair of rhomboid vents on the upper back and a single oval duct near the rear wheel.

Most of the mechanical and systems components are exposed to view, their raw alloy enhances the elemental design of the Exodus.




Even simple things, like the rearview mirrors, exhibit the character of the Exodus. They're nicely contoured to reduce wind resistance and also include a turn signal.




Just picture yourself at wide open throttle coming out of a turn:

What provisions are provided for stopping & remaining upright. Slow maneuvering and operation in traffic, i.e.; the real world.
I see no out riggers to drop and it looks impossible to use your legs to balance you at rest.

It's easy to keep the Exodus upright by just putting your feet down the same way as with a normal motorcycle. If you look at our blog, we've posted a photo of a view looking down from above towards the rider's feet, and another photo of the rider sitting in the bucket seat with his feet on the ground.

One feature of the Exodus that makes this so easy is its low center-of-gravity (CoG), which is almost a foot lower than on a normal motorcycle. With this low CoG, the Exodus requires very little effort to be held upright. In comparison to a normal motorcycle, it seems it wants to stand up by itself. So, when the rider wants to come to a stop, he just brakes and puts down his feet, just like with any normal motorcycle. But actually, he needs less force to do so. The rider can stand there indefinitely holding up the Exodus with very little effort.

Additionally, when the rider wants to get out, or is just tired of paying attention to keep the Exodus upright, he can use the power center stand by pushing a button on the right grip. When you press that button, the center stand comes down in 3-4 seconds. When you want to start out from a stop and you're on the center stand, you just drive away, and the stand automatically retracts. You can see that in one of our videos: The Exodus starting out for another ride.

Of course, there may well be a role for outriggers, especially for off-road use and completely enclosed vehicles, and we may introduce them at some point. But even then, our approach probably will be through the use of much smaller "feeler arms", basically 8-10" long robotic jointed extensions that intelligently apply variable force to the ground as needed. Additionally, we've been working on other technology, similar to what Segway uses, that eliminates the need for either outriggers or heavy gyroscopic stabilizers. You'll hear about these approaches in future updates.

With a powerful engine and the ability to perform, you can be sure that stopping this machine is tricky. A good Air Brake System combined with Air Brakes and a couple of stablisers (or something as simple as Air Assisted jocky wheels) this could be the bike of the future. If anyone is interested in the air options please visit me at http://www.airbrakesystems.co.uk I would be happy to discus the options with you. As for all us bike (and other vehicle) entheusiatsts. Do you remember the spider man movie, when he said ' with great power comes great responsibility' I would like to modify it to 'with great power comes great brakes' Thanks for listening.

Thanks for your suggestions, Alan, you make some good points. We agree that excellent brakes are essential for a high-speed vehicle like the Exodus, that's why its brakes are so large and why we relied on BMW's “Integrated” ABS system that modulates front/rear braking. We'll take a careful look at your “Air Brake System” to see how it might help, it well could be appropriate for our off-road variant, where military requirements, such as systems logistics and training, are crucial considerations.

As for “jockey” wheels, we haven't found them necessary for the Exodus, at least for moderately-experienced riders, although they might be helpful for novices. In that case, their use would be similar to "training wheels" for bicycles; they might help the first time someone wants to ride it, but they'll never learn to ride it well if the training wheels stay on. As we said in reply to a prior comment, we might offer something like them on future models, but even then, we're working on articulated robotic arms that can apply well-modulated ground-forces for a range of handling opportunities, not just stabilization at low speeds (think about the "steel shoe" used by flat-trackers). Moreover, we're working on Segway-type low-speed balance mechanisms that will work even without external arms or heavy gyroscopic stabilizers. Please stay tuned for upcoming announcements.

Thanks, David. We know you've worked on similar concepts so your compliment is all the more appreciated.

I really like the bike, really something special. The only thing that I have not seen mention of is storage capacity. Does it have any? If so how many Liters? Thanks!

John

Thanks for your comments. We've been giving storage a great deal of thought. We have several full body designs in mind that do include storage above and behind the engine, including what you might call a "shooting brake", or "station wagon", that looks a bit like the old Ferrari "Bread Wagon". The aerodynamics even work pretty well with more storage. We did have a luggage rack attached to the Exodus at one time, but took it off so it wouldn't confuse people, but we sort of like that alternative as well, it's lean and mean and can be removed for those situations when aerodynamics are more important.

Currently, there's very little room within the engine surround, but we could pick up a bit of storage if we were more stringent with component layout, versus ease of tuning and repair. However, we don't have much room with the turbo configuration for the "G" version, which appears to be the only model we're going to release this year. We think the turbo performance, which is pretty amazing, makes up for the lack of storage.

However, there is about a a half cubic foot available inside the main spar between the driver's legs. We intentionally left that volume unused as we decide what kind of communications gear options we should offer. Nonetheless, we have been thinking about putting a small storage compartment there as well.

Someone suggested we offer something like saddlebags or panniers for the rear of the body, perhaps around the engine surround, and we think that might make sense. Another person likes the idea of a small pouch or storage pack that would rest on the main spar in front of the driver. We have some drawings of such a pack and think that might work as well. Moreover, for a full body shell, we can move the radiators to the front, which then frees up even more volume above and behind the engine.

Do any of these alternatives sound right to you?

This bike looks gorgeous! The name "intercontinental ballistic motorcycle" truly applies to this bike! The riding posture is good for long rides, but this is so different from the conventional bikes, http://microsoftoutlookemails.com/ it would take some time to get used to this. I'm off to search videos of this bike in motion! Awesome job!

Thanks, Stevenson, we're glad to hear you appreciate our effort. Yes, the Exodus is great for long rides, as we've said before, it feels like you're piloting a small jet airplane. Additionally, the mid-engine design is rather good for all-around riding, especially if you think about the enclosed and off-road versions we're working on. If there is one thing that might be a problem with inner-city traffic for some people, it's the "need" to put your feet down at every stop light. Rest assured, we're working on a couple of solutions to that "problem" so you can rely on the machine to keep you upright even when you're stationary. Please stay tuned...
