Electric Superbike 'Leap Forward'

MotoCzysz, have announced the availability of its Electric D1g1tal Dr1ve (eDD) kit, which could be suitable for manufacturers or teams wanting to develop an electric race bike for this year's inaugural TTXGP electric world series. MotoCzysz press release follows...

MotoCzysz Electric D1g1tal Dr1ve System
MotoCzysz announces the most integrated electric drive available. The first product from a family of integrated drives being developed by MotoCzysz is designed and engineered specifically for high performance electric motorcycles. The eDD system integrates advanced technologies with new proprietary industry first solutions. For individuals, teams and companies interested in building a high performance electric motorcycle, the new MotoCzysz Digital Drive system is the most advanced integrated electric drive system available.

MotoCzysz power, your imagination
Electric drive systems are rapidly moving beyond the resources available to individuals and small teams, but the vision and ability to build a next generation e motorcycle has not. With the MotoCzysz eDD system an individual or team can use their imagination and build a highly competitive proprietary race bike or utilize parts from a donor bike to build the electric motorcycle of their dreams.

Motor
The MotoCzysz liquid cooled 75kW/100hp electric motor is one of the highest torque/density motors in the industry (250+ft/lbs/340+Nm continuous 77lbs/35kg). The integrated permanent magnet solution generates more torque while being more efficient than any comparably sized AC induction motor. The MotoCzysz cooling system elevates the motor’s nominal power output closer to the motor’s peak power output. The MotoCzysz motor can deliver a continuous 75kW (100hp) and is 93% efficient under continuous heavy load (140C). The motor is available to accommodate either right or left hand chain drive.

Controller
The MotoCzysz LQ 240V 85kW Controller is specifically optimized for the motor, in both function and packaging.  Accepting 240V and 350+ amps the sealed Controller contains ALL the high voltage components and plugs directly into the motor, resulting in a nearly completely wireless (high voltage) system.  The Controller receives battery motor and rider command data and adjusts current accordingly.; The Controller software has multiple embedded maps for setting or customizing functions like torque contouring and overall power settings.

Batteries
The new Digital battery pack utilizes high density, high discharge LiPo (Lithium Polymer) cells. Each pack is embedded with monitoring capability that sends vital data wirelessly via infrared to a Digital Vehicle Management System and ultimately to the Controller. Additionally, each battery pack houses an LED display that indicates the overall pack as well as individual cell group data. Each battery pack weighs less than 18lbs and effortlessly “snaps” into the “suitcase” chassis. The “suitcase” holds 8 battery packs for a total energy storage of 10kWh.

Chassis
MotoCzysz has designed the “suitcase” chassis to optimize the mass location and vehicle’s overall on board energy density. The chassis accommodates virtually any modern double sided swingarm from a 1,000cc motorcycle. The suitcase also ships with a matching top plate for the mounting/fabrication of a new or existing front end.

Fully Charged

Above is a trailer for the new Mark Neale documentary Charge. The movie is narrated by actor and motorcycle fan Ewan McGregor and documents the world’s first electric motorcycle race, the TTXGP, at the 2009 Isle of Man TT.

The movie does a great job of describing the excitement and technical challenges of producing an entirely new breed of racing motorcycles. 2010 looks like it is going to be a watershed year in terms of motorcycle technology. It now seems inevitable that electric technology will displace internal combustion engines in the coming years. Remember photographic cameras that carried rolls of film? What about cathode ray tube computer monitors and TV screens? In a decade or so I expect that exploding petrol as a means of propulsion will seem rather quaint and young kids will scratch their heads and wonder how it was ever possible.

Mavizen Factory Training and Support



Mavizen, winners of the inaugural 2009 TTXGP (electric MotoGP) race are now offering a 4-day technical training course on electric propulsion systems throughout 2010. The course compliments the TTX02 race bikes they produce that are now on sale. Course topics include: Batteries, Motors, Controllers, Chargers, Battery Management Systems, Safety Systems, Construction & Wiring Considerations. The course is currently advertized at £900 for all four days. Visit their web site for more details.

CRP Racing have released details of the TTXGP electric race bike they have built based on the Mavizen TTX02 electric propulsion system...

Source TTXGP Press Release:

On January 14th Lord Drayson, UK Minister for Science and Innovation, unveiled the super sports electric motorcycle built by CRP Racing. CRP Racing is very pleased to unveil its ground-breaking motorcyle in terms of innovative technology. This has been demonstrated with the project of the bike eCRP 1.0, where the UK-based company, TTXGP, has collaborated with the Italian company CRP Racing.

eCRP 1.0 represents the Italian style and design with a strong "racing" look, easy to handle for its dimensions and shape, whose colours remind the Italian flag with the aim to promote that values leading the made-in-Italy a unique and distinctive factor.
