Voltra Electric Motorcycle Concept

Ironically, one of the features designers of electric motorcycles seem to have the hardest time getting away from is the gas tank. My hunch as to why is a motorcycle just looses too much of it’s identity as soon as you take away the tank. Eventually our minds may learn to accept the tanks absence. Until then Dan Anderson‘s Voltra electric motorcycle concept, with it’s trellis frame forming the skeleton of a gas tank lets our minds wander just far enough to be comfortable with the no tank look.
Suspended on the end of the vestigial tank structure is a cafe racer inspired seat and tail section hinting at Dan’s inspiration for the bike. This 4th year University of Western Sydney Industrial Design student has a deep rooted respect for the culture of ICE motorcycles and their design. His father Chris successfully raced Norton Manx in a classic race series in Australia in the late 80’s and early 90’s and currently owns a Commando and a few Ducati’s. He was Australian champion 3 times and state champion 6 or 7 times. Dan’s personal bike is a Ducati Pantah 600 that he restored himself.

 

The striking aesthetics of the Voltra bike speak for itself.  Combine the visual presentation with cool features like a removable instrument cluster that doubles as a key and records data for review after the ride and it would have the most vain of squids jumping at the chance to add it to their garage furnishings. However, the more you dig into the design the more you realize the beauty is more than skin deep.

Earlier this year MotoCzysz unveiled an equally stunning carbon fiber framed E1PC that has the batteries attached to the side of the frame in 10 modular packs. Dan took a quite a different approach. What appear to be side panels on the Voltra are actually part of the carbon fibre monocoque frame. It is designed as a load bearing exoskeleton that has a hollow cavity inside to hold the batteries.

The AC induction electric motor resides in a cast housing that doubles as a pivot for the trellis swing arm. This design not only makes for a rigid connection between swingarm and frame, it provides a consistent chain tension through the travel of the rear swing arm.

The motor and lithium ion batteries are directed by a programmable control unit. The design translates to a 441 lb machine with 129 Nm of torque and a top speed of 124 mph. All very realistic specs based on today’s technology, a further testament to Dan’s thorough research. As with all electric vehicle designs weight and energy density of batteries will come down and specs will only get better.
Be sure to have a look at the gallery below as there is a lot more information in the sketches and renderings. He includes ergonomics analysis for average, large and short riders, analysis of stressed members of the construction and a view of how the motor is fitted inside the swingarm pivot.
Dan told me I have the most information of any site on the net so let me know if I missed any information contained in the pics. I’ll also mention Dan is in his fourth year and looking for a motorcycle company to begin his career with and he is open to any form of propulsion. Someone might want to snatch him up before he gets together with Tom Miceli and Tony Helmholdt and creates more competition in the market.

Tron Lightcycle : The Future Vehicle

As Ducati gets ready to unveil its 2011 line-up in Milan tomorrow, there’s one bike we are more than certain won’t make the showcase: the Ducati Tron Lightcycle. While Ducati is expected to make a cameo-appearance in the new Tron Legacy movie, we don’t think the Bologna-based company’s product placement will go quite as far as this Ducati fan’s imagination. One of the better photoshops we’ve seen in a while, the oil filter protruding from the bottom of the bike makes us squirm with delight

Zero MX : Zero Motorcycles

Once you’re in the air, it’s all about the landing.
The Zero MX takes our revolutionary electric motorcycle technology to the track. Incredibly tough and lightweight, the Zero MX uses our newly developed suspension system to absorb aggressive terrain and give you an edge. Combined with our state-of-the-art Z-Force™ technology and ultra-light frame design, the Zero MX is agile and fast where it counts.
By developing a custom suspension system we have made the Zero MX highly responsive while maintaining an industry leading power-to-weight ratio. During aggressive riding the advanced suspension system and alloy wheels take the hits while smoothly maintaining control. Intensity combines with silence to open up a new world of riding possibilities.

Frame – Sculpted Aircraft Grade Aluminum Means Lighter, Stronger, and Faster At the core of the Zero MX lies the ultimate dirt bike frame that we’ve engineered from the ground up and hand crafted using aircraft grade aluminum. The resulting combination of lower weight and higher strength means more responsiveness. In the turns and off the line this translates into greater acceleration. To make the frame even more durable each one is shot-peened and anodized. Hydroformed top tube for increased strength & reduced weight Massive swingarm for increased strength & torsional rigidity (better cornering and tracking) Large cylindrical swingarm cross tube for increased stiffness & suspension response Thru-axle rear hub for exponentially increased strength & rigidity Entire frame is shot-peened and anodized for resistance to corrosion and abrasion Organic frame gusseting for increased strength & smoother body lines Bodywork is highlighted with new color graphics

Motor and Energy– High Torque and Acceleration Fueled by Zero Motorcycles’ proprietary lithium ion power pack, the Zero MX delivers more torque than any other motorcycle in its class. This is made possible by our power pack’s ability efficiently dump an incredibly high amount of power as soon as you punch the throttle. Using an advanced monitoring system, each cell in the power pack is individually controlled during charge and discharge. The charger integrates into this system and uses a specially developed charge profile to optimize the power pack’s recharge time. Think of it this way, fuel systems are to gas motorcycles what electrical systems are to electrical motorcycles. Where others use a small carburetor and fuel pump, we use a highly tuned fuel injection system. We’ve found a way of rapidly flowing more energy out of our power pack than any of our competitors. This means more acceleration and more fun.

Drivetrain – Larger Chain and Sprockets for Increased Durability & Longer Life To accommodate the Zero MX’s increased traction and ability to accelerate in the dirt we use a hardened steel 420 chain and direct drive gearing. The result is a stronger and more durable drivetrain that puts the power from the throttle directly into the dirt. Hardened steel 420 Chain Front & rear accompanying 420 Sprockets Larger rear sprocket mounting/bolt pattern for increased durability and better management of high torque acceleration

Handling – Faster Turns and Bigger Berms We want you to be able to take full advantage of the rapid acceleration the Zero MX has to offer. To do this we’ve taken our riders’ handling wish list and built in the features. The result, this electric dirt bike gives you the control you need to for the acceleration you want. Direct mount (to fork crown) double clam stem for increased rigidity and control Increased rise and reduced reach stem for better control & stability Wider, taller, and stronger full sized dirt bike handlebar Higher strength hardened race headset for longer life & smoother turning

Brakes – Stopping on a Dime in the Dirt Because you’ll be going faster and harder on our electric dirt bike we’ve added a few things to help slow you down. The 2010 Zero MX electric motorcycle features beefier brakes all around. 4 piston calipers front and rear 9” (224 mm) rotor in front and rear Increased reservoir size for more responsive braking under high strain

Instrument Panel & System Upgrades – Quick Look & Easy Access A quick look tells you everything you need to know on the Zero MX. We’ve taken all the important dials and switches and securely located them in a new instrument panel. Accompanying this, is a newer wiring system for increased safety and electrical system longevity. With a bike this desirable, you’ll also be excited to know that this motorcycle comes with a keyed ignition. Easy access to gauges and switches – ‘quick look’ clustered instrumentation “Armed” light for increased awareness & safety Key switch with solenoid for added safety, peace of mind, security and ease of use Flush mounted rockers switches for speed settings (easy/sport and 30/50mph) Integrated battery power connector for ease of use and durability Integrated battery fuse for added safety in handling and adverse circumstances

Wheels and Tires- Hook Up on Technical Tracks The Zero MX custom alloy wheels are designed to reduce unsprung weight while not comprising on strength. During acceleration instant torque is efficiently channeled into the dirt through a beefy rear tire and directed using an equally aggressive front. Tall knobbed and grippy full size rear tire - 17X3.5 Large lugged high strength rear rim 17 x 2.5” Thicker 32h 12g spokes Custom oversized & reinforced hub 1.6x19 front wheel Aggressive front tire 19x3.0

Suspension - Designed for the Track The Zero MX uses our newly developed suspension system to absorb aggressive terrain and accommodate larger riders. Taking advantage of the motorcycle’s low weight, the inverted front fork is one of the beefiest, lightest and most responsive in the industry. Riders can quickly dial it in using the externally adjustable compression and rebound damping. On the rear, our rigid double diamond swing arm keeps the wheel planted using a newly developed custom rear shock with a fully adjustable spring preload and easily tuned damping. Zero designed lightweight front end Inverted front fork to reduce unsprung weight (48 mm fork leg) Fully adjustable rebound and compression damping on the front Custom rear shock with adjustable spring preload and damping Unique double diamond aircraft grade aluminum rear swingarm for reduced weight and increased torsional rigidity

Extreme Package – Adding more power to already high performance We offer an ‘extreme package’ for those wanting to ride even harder and faster. The upgrades include a stronger motor and a stronger/smoother front fork.

Higher Power Motor – More Acceleration & Speed

This is your motor if you’re looking to leverage all the latest Zero MX features and push your motorcycle (or yourself) to the limit. It offers more torque and increased acceleration.

• Efficient German built high torque/ high power perm motor
• 10% more power than the stock motor for greater acceleration
• Greater acceleration

Mavizen TTX02 an electric superbike

Overview Mavizen TTX02

The TTX02 is the world’s first production electric superbike. With a number of world firsts combined with the proven chassis from KTM and drivetrain from the TTXGP winning Agni bike; the TTX02 is an exclusive opportunity to procure a platform for development and racing across the entire TTXGP racing programme. 
Our race proven technology is primed for the track however if you would like to make your TTX road legal (where permissible by local laws and regulations) we can provide the components to make this possible. We advise you to contact your national motor vehicle licensing authority for advice on obtaining single vehicle type approval.
Please be advised, that although Mavizen will help you to obtain this approval, this in no way transfers any liability or warranty risks to Mavizen. 
Please contact us for more information before you proceed.

PERFORMANCE:

The TTX02 delivers performance, with incredible off-the-line acceleration and a formidable top speed of 130mph depending on the gearing.
Contrary to general perceptions, this electric motorcycle is 15kg lighter at 170kg than the same bike with a petrol engine without fuel or fluids.
With a 7.5kWh battery pack the range is enough to complete TTXGP races at full pace (25 miles +) and can be up to 110miles during road use.

RACE HERITAGE

The TTX02 was initially built for racing, as an off the shelf race bike.  A TTX02 has competed in every round of the TTXGP season, with three in the Final at Albacete, Spain.  This has been a fantastic development opportunity and the lessons learnt from the experience have been directly transferred to the bike.

CHEWII – ON BOARD PC

A touch screen visual display unit informs the rider exactly how the bike is performing, providing real time information on temperatures, current draw, voltage and power usage.  The CHEWII system runs on an Intel chip and has WiFi, Bluetooth, GPS and USB, allowing remote access for checking the battery charge or uploading new settings.

HOT-SWAPPABLE POWERTRAIN
 
The entire powertrain, including batteries, motors and controller can be removed in less than 5 minutes.  This negates the charging time and means that on trackdays or for racing the bike can quickly be back out on track.
The powertrain is housed by a structurally reinforced, Kevlar lined, carbon fibre box which replaces the semi-stressed engine.
The TTX02 powertrain is extremely versatile, with many easily configurable settings for power delivery and efficiency and it is also easily adapted for other applications, even boats!
