It’s the first electric superbike and though its range is considerably less than the first modern four-stroke superbike, the 1969 Honda CB750, its top speed of 125 mph (200 km/h) is almost identical.
Built to demonstrate the potential of electric sports motorcycles for the first emissions-free Grand Prix, the initial prototype is based on a Suzuki GSX750 frame and running gear and runs two 43 bhp Agni Lynch Electric motors arranged in line with the frame. Together, the motors produce 125 Newton Metres of torque and both have been modified to withstand high RPM using Kevlar-reinforced armatures. The vision is to create a lightweight, carbon fiber framed 2WD TTX02 with "hot swappable", 20 kilowatt hour battery packs, regenerative braking and a production run of 50 machines in 2010 with a target price of UKP20,000.
Though capable of 200 km/h with longer gearing, in the form .......

..............presented yesterday, the bike is currently geared down to 110mph for greater acceleration which is quoted as 0-60mph in 3.5 seconds – not quite superbike territory, but certainly in the realms of supercar acceleration.
We’ve been raving about the potential of electric motorcycles for several years now and until today, only the Vectrix Electric Superbike prototype (see original story about the Robrady Design in 2005 and unveiled at last year’s Milan Show) of the dozens of electric two-wheelers we have covered has really promised genuine sporting performance on a par with large capacity motorcycles.
Similarly, we have enormous belief that the world’s first clean emission Grand Prix to be held at the Isle of Man during TT race week in June 2009 will flush out some really fast electric bikes for the first time.
The TTX01 was produced under commission by the organisers of the TTX GP in order to demonstrate the potential of the electric motorcycle. TTXGP founder Azhar Hussain told Gizmag that the bike was created because, "the public's perception is that electric motorcycles just aren't credible as race machines and to overcome that challenge, we built a bike."
"We've had many people contact us wanting to become involved in the race in 2009 or beyond, but there is just no electric machinery available as yet and that has been one of the major aspects of enquiry", said Hussain. "Now we've proven that there is genuine performance potential in electric motorcycles, we expect to begin turning the tide of public opinion."
"Seriously, we need to change the way people see electric motorcycles if we're going to change their buying habits and a large part of what we're doing with the TTX GP is pioneering those changes."
Hussain said there were currently around 60 teams preparing to compete in the TTX GP, with most opting for electric motorcycles, but several working on hydrogen machines and one in the process of developing an electric fuel cell hybrid. "If half of those people get to the line for the first race in June I'll be happy", he said.
"We're currently working with some of the overseas teams, 22 of the 60 are from outside the UK, to help them with getting riders who know the course well enough to be competitive, so it's fair to say that a lot of these teams are very serious about winning the first race - it's an historic event and the importance of winning the first of what we expect to become a very important event in history has not been lost on the competitors", said Hussain.
"We'll be having a closed track day in April and an open track day in May where all the competitors will get to see how competitive they are. Those days will be announced fully when we have decided on the race circuit to use, but it is certain to be one of the major racetracks in the UK", he said.
"So another aspect of what we're doing is to ensure that there are race bikes available if people want to compete, and the next step is to take advantage of the inherent strengths of the electric motorcycle. The GSX Suzuki frame and running gear are heavier and more robust than they need to be, and the size of the motorcycle, particularly its frontal area, can be reduced enormously - the GSX has a four cylinder motor which is much wider than an electric motor and hence we'll be able to make the next machine both lighter and faster, even if we don't get any more horsepower from the motors.
"The idea behind using a carbon fibre frame is to reduce weight as much as possible and to use the greater freedom of construction to enable battery swapping", said Hussain. "We're seeking suitable partners to work with in several aspects of the bike, so if there's anyone out there wishing to collaborate, we'd be more than pleased to hear from them."
Only one production motorcycle currently exists with a Carbon Fibre frame - the Bimota DB7 Oronero.
"The bike uses the Cedric Lewis-designed Agni electric motor which already holds the unlimited world electric water speed record of 68 mph set in 2005, and plans another record attempt with much higher goals.".
Cedric Lynch invented the Agni Motor in 1983. The Agni Motor achieves a remarkable 93% efficiency and it maintains high efficiency over a wide range of loads and speeds. It runs on D.C. up to 84 volts and the low shaft speed and high torque enable the use of a simple, cheap and efficient transmission in most applications.
One of the most significant aspects of the next prototype will be 2WD according to Hussain. At present, both engines power the rear wheel and Hussain says, "by adding an additional motor into the front wheel to create a 2WD motorcycle we can achieve significant improvements to handling and roadholding, particularly in wet conditions." Yamaha has been working on such a system for several years now.
"The aim is to have a bike which is road legal from the get go, and can perform well on a racetrack by unscrewing the mirrors and putting on the right tyres, and our target price is UKP20,000."
"One of the other critically important aspects of the next version of the bike is to have hot swappable batteries. If you want to go racing, no-one is going to charge their battery quickly enough in a pit stop, and it must be hot swappable because the computer-controlled power management system we have on the drawing boards will need rebooting if you cut the power. Accordingly, we're shooting for hot swappable 20 kilowatt hour battery packs, even though the current machine only has a 14 kilowatt hour pack."
Right now, the 20 killowatt hour battery pack weighs in at 75 kilograms, and fully charged, at road speeds, that should give the bike around 50 miles - obviously everything is geared around completing one lap of the 37 mile TT circuit at race speeds, but talking in roadgoing terms, the recharge time with a standard 13 amp power supply is under two hours."
"We'll be using the TTX01 as a promotional vehicle during the first six months of 2009 leading up to the TTX GP, with motorcycle journalists being invited to ride the machine to verify that it performs as claimed, and there will be a battery-powered European tour taking in Portugal, France, Germany and Italy promoting the TTX GP where we'll be using the bike."

A minister from the Isle of Man government, the Honorable John Shimmin, will be on hand in Las Vegas on November 3 to help launch Mavizen's TTX02 electric superbike. This electric motorcycle is meant to be a bootstrap vehicle for teams wishing to compete in the TTXGP racing series. The specs have not been released but obviously it is meant to perform better than the TTXGP winning entry from Mavizen's collaborator, Team Agni. The TTXGP race is part of the TT race series held on the Isle of Man, and bikes competing in this race have to complete either one or two 38 mile laps over mountainous rugged terrain. (see TTXGP UK Championship 2010 agreement, and other TTXGP news)
Until recently the all electric superbike class of motorcycles seemed to be occupied solely by Mission Motors. However over the last two months we have seen Lightning Motors run a prototype of their superbike at the Bonneville Salt Flats, they expect to sell production models during 2010. And now Mavizen is getting ready to sell the TTX02 in Q1/2010. Additionally other companies may enter the superbike market with Brammo, Electric Motorsports, and Zero Motorcycles being likely contenders. (See Lightning Motors has second fastest electric motorcycle, ahead of Mission Motors)
Mavizen has been leaking a series of tease photo's prior to next week's launch. Obviously details will be revealed next week but that hasn't stopped informed speculation from trying to figure it out ahead of time. One of the teaser images is the usual blur job but with a bit of photoshop detective work a writer on Asphalt and Rubber found an unblurred thumbnail which indicates Mavizen is using a KTM RC8 as the frame of the TTX02. Installed in the frame is two Agni motors.
The Mavizen announcement also claims the TTX02 will be "the first factory production vehicle to be delivered with a dedicated IP access and connectivity to the network". What this precisely means is yet to be seen as for example other vehicles have had data connectivity to some sort of network, e.g. the Tesla Roadster can phone home with data that Tesla turns into vehicle improvements.
The Mavizen TTX02 will be unveiled on Tuesday 3 November at the SEMA show in Las Vegas (Press conference 13.00hrs in the Making Green Cool Zone). The bike will be unveiled by the Honourable John Shimmin, MHK, Minister for Local Government and Environment, Isle of Man Government. A full technical specification and high resolution photos of the bike will be available at the launch.
TTXGP is developing a global programme of low-carbon motorsports events working with the Auto-Cycle Union, British Motorcyclists Federation and the Fédération Internationale de Motocylisme to provide a platform for competition to drive technology and innovation into the next generation of motorsports.
Mavizen has decided to offer a new electric bike based on the previous winner of the TTXGP so that other teams can have a solid foundation to build on for next year. The TTX02 is based on the KTM RC8 with a Agni powerplant. The twist is that they call it a "laptop on wheels" because of all the electronics it packs on top of what is strictly required to control the electric motor (dash-mounted computer that runs Linux, has wifi connectivity and a web-server, etc). Posted Image All this hardware and software might seem overkill for a racing bike, especially since it no doubt adds a bit of weight, but it probably compensates for that by giving the teams who will buy one more information about their performance and more ways to customize the ride. If the bike is able to tell you in great details how you're doing, it's probably easier to make adjustments (both to the bike itself and to the way it is driven) to shave off precious seconds from your laps.
Technical Details The twin electric motors have a peak horsepower of about 100hp and they get their electricity from a lithium-ion battery. 3 different batteries will be offered, with 11kWh being the biggest one (it should give the bike a range of at least 38 miles, enough to complete the Isle of Man race).
Here are some more specs:
Top Speed: 130 MPH Core operating system is open source Linux USB based system bus allows virtually unlimited number of peripherals to extend the capabilities of the machine with plug'n'play Dry weight: 110kg (without batteries) Seat height: 805 mm Ground clearance: 110 mm (depending on battery and suspension configuration) Wheelbase: 1,430 mm Frame type: Chromoly trellis frame, powder-coated Rake (fork angle): 23.3° Trail: 90 mm Front suspension: WP-USD, 43 mm Front suspension travel: 120 mm Rear suspension: WP-Monoshock Rear suspension travel: 125 mm Front tyre dimensions: 120/70-17 Rear tyre dimensions: 190/55-17 Front brakes: Double disc. Brembo Front brakes diameter: 320 mm Rear brakes: Single disc. Brembo Rear brakes diameter: 220 mm
Here's a video (below) that shows the TTX02 in action and elaborates a bit on the thinking behind its creation. It's a bit over the top, with some "majestic" music that tries to make us believe that this is a world-changing bike... But if you can get passed that, it's still a pretty cool piece of technology that is no doubt helping engineers figure out how to make better electric vehicles, and to my mind, that's the main reason why electric vehicle racing is important.
The Mavizen TTX02 should be available in Q1 of 2010, with "a limited production of 50 units". The target price for a complete bike with a Circuit Pack is £25,000 (about $41,500).

We've long argued that electric motorbikes make sense - low-emissions, quiet operation, instant torque and hardly any maintenance compared with their gas-guzzling cousins. The sluggish reaction of the established industry players to this e-revolution has created an opportunity for names like Brammo, Vectrix and Zero to try their hand, and now a brand that dares to put the words "electric" and "superbike" in the same sentence. Launched last week in Las Vegas, the 130+ mph, GBP25,000 Mavizen TTX02 is based around a KTM RC8 frame, ships with two Agni motors and boasts a hot-swappable battery and drivetrain architecture. Born from, and bred for, the world's first electric GP, the bike is a "laptop on wheels" that runs on the Linux OS, comes with with integrated IP connectivity and a USB based system bus for open source engine management, and although it's not being sold as a street legal machine, TTXGP founder Azhar Hussain says the package can still provide a pathway from the racetrack to the road.
Mavizen TTX02 - what you get
On first impressions there's no doubt that the looks the part. The addition of Mavizen's own fairings to the RC8 chassis, plus the obvious change in color scheme, the twin Agni motors and the absence of the distinctive headlight help to differentiate the TTX02 racebike from the KTM.
The bike's top speed is specced at 130+ mph (depending on gearing) with 70kw peak and 40kw continuous power. The range is 25-50 miles using the 6kWh Circuit pack under track conditions, but this can be stretched to 130 miles "under regular road use" with the 11kWh Snaefell Pack according to Mavizen. There's also a yet to be finalized 3kWh Sprint pack on offer which provides six miles of track use.
Stopping power is provided by 320mm double disc Brembo's at the front and a 220mm disc at the rear while the drive train is from the Isle of Man TT winning Agni bike with the "interchangeable capacity dependent on the pack selected during purchase".
Dry weight is 110kg which jumps to 160kg once batteries are added (Circuit Pack ) and in a specification we're not used to discussing for a motorcycle, the OS is Linux, although Mavizen says it's also tested against Windows and may look into Android.
Mavizen TTX02 - what else you can get
The TTX02 is first and foremost a racebike that will give a new breed of competitors a development platform with which to take a place on the TTXGP grid, or any national or FIM championship. "Mavizen is about growing the grid," says Hussain, stressing that the company"wants to be a platform provider and facilitator for the TTXGP, not a competitor." Competitors who choose the TTX02 platform will be encouraged and expected to tweak the bike to gain a racing edge, and the swappable drivetrain and versatile management system is designed to facilitate this.
The onboard IP connectivity also makes it easier for fledgling race teams the ability to configure the bike themselves, and for regular buyers, this means that the bike can be remotely diagnosed and tweaked by Mavizen if there's a need for modification. Hussain's aim is to take full advantage of the "laptop on wheels" potential offered by electric motorcycles so that "you can just log onto the bike as if you are logging onto a website".
But what if you want to get take your GBP25,000 superbike to the streets? The TTX02 is built on a homologated chassis and the clever part is that although it's not being sold as a road legal bike, it still ships with a wiring loom fully integrated into the frame. This means that when you buy all the lights and other bits and pieces required to make it road legal (and this of course will depend on the jurisdiction you live in), the process becomes much more straight forward.
What next?
Mavizen is targeting March 2010 for shipping of the TTX02. Initially sales will be online and a limited production of 50 units will be brought to market. The target price complete with a Circuit Pack is £25,000.
The versatile architecture around which the bike is built also positions Mavizen to create a stable of bikes based on a common power pack concept, so we don't expect that the TTX02 (which we see as a groundbreaking step towards the day when e-bikes will outstrip their petrol-driven counterparts) will be the last we hear from these guys.
We'll be riding the Mavizen TTX02 soon, so stay tuned for a full review. Meanwhile, there's loads of exclusive pics of the very first TTX02 in the Gallery.
