Early life and career
Born in Merton in London, Eisenberg left school at 15 after his GCSEs to take a job in a health shop. A competitive bodybuilder at the time, Eisenberg said he took the job to get discounts on nutritional supplements.
While working at the store, Eisenberg wrote a monthly newsletter on the science of nutrition and, in 1993, self-published a book on the same topic. Eisenberg used the profits from the book to start supplying protein supplements to other bodybuilders.
Eisenberg was a fully qualified senior gym instructor, specialising in nutrition and conducted two years of endocrinological research at the British Medical Research Centre and Pharmaceutical Association. providing the knowledge and passion to form Maximuscle.
He went to design and technology college in Barnet, London, after doing his GCSEs. During his GCSEs, he was sponsored by Digital for a new XY axis robot, when just 15 years of age for one of his Technology GCSE projects. He further featured in the Sunday Times for his rear wheel engine powered cycle. Even though Eisenberg confessed to being self taught in the world of engineering, welding, tuning and engines, he trained and achieved his certification at H&S Rolls Royce Portsmouth for the C250 series turbines, as used in his world record setting land speed motorbike.
Business
Maximuscle
In 1995, Eisenberg founded sports nutrition brand Maximuscle with £3,000. Initially supplying whey-based supplements, the company's product range grew to include drink powders, edible gels and protein bars.
Maximuscle was the first UK sports nutrition brand to have its products screened under World Anti-Doping Agency rules.
In 2010, Maximuscle was selling £80 million worth of products per year. In 2011, GlaxoSmithKline bought Maximuscle for £162 million. At the time, Maximuscle was Europe's best-selling sports nutrition brand. Zef Eisenberg continued on in a consultancy role with GSK for Maximuscle. The German food giant Kruga (with 2 Billion Turnover) bought Maximuscle from GSK in Jan 2018.
Maxicorp
Eisenberg ran Guernsey-based Maxicorp. The company is active in property investment, autosports racing and engineering.
The property business has bought and sold properties worth around £210 million in London, the Channel Islands and Gibraltar. It bought BBC Villers House in 2012 for £16 million. with plans to develop the largest Ealing Cross Rail Station, iconic office block and retail.
The engineering autosports arm builds bespoke high-speed vehicles. It also designed and manufactured the Eisenberg V8, the world's smallest and lightest V8 engine motorbike. The Madmax ultra-speed motorbike race team is part of Maxicorp. Maxicorp is the registered trademark holder of Eisenberg and Madmax in the UK and EU.
Madmax Race Team
Eisenberg set up Madmax Race Team in 2011 from Guernsey. The Madmax is a specialised engineering team that works with the best to develop some of the world's most extreme and powerful motorbikes, cars, quads and land speed vehicles. The Madmax Race Team is behind multiple world land speed records on bikes, quads and cars, with over 50 land speed, British, world and Guinness records to its name, including the world's fastest electric unfaired bike.
Electric Motorbike Racing
Eisenberg who has been a long time fan of the iconic, Isle of Man TT, sponsored three times IOM TT podium winner Daley Mathison and Dr Miguel Gimeno Fabra on the Nottingham of University (NOU) Electric motorbike under the Zero TT class for 2019. The NOU bike had been designed to be more powerful and capable than all its previous years. The day before Madmax Team rider Daley Mathison was meant to ride the Zero TT bike to number one podium position, sadly Daley, was killed in the Superbike crash. Zef Eisenberg promised Daley's wife Natalie, and family that this was unfinished business and he would take the NOU bike to world record glory himself as a tribute and final send-off to Daley. The Madmax / NOU electric motorbike was re-engineered to be more powerful than ever and on Sept 21/22, Eisenberg, along with the help of Dr Miquel achieved four FIM world speed records (at Elvington, Yorkshire), wearing Daley's actual 'daisy' kneesliders and with Daley's wife Natalie present, Eisenberg fulfilled his goal of making the bike into a world record bike for Daley. This technological feat achieved in record time, inspired the Royal Automobile Club (RAC) club to name Eisenberg as the winner of the SIMMS award, a highly prestigious accolade, only given in years of exceptional motorsport performance.
Eisenberg V8 Motorbike
The autosports arm builds bespoke high-speed bikes and cars. The brand manufactures the Eisenberg V8 (EV8), the world's smallest and lightest V8 engine. under the Eisenberg Racing banner. Eisenberg has created a partnership with Prodrive, one of the UK's largest motorsport engineering brands to develop a limited production run of the 480hp motorbike. The bike is considered to be one of, if not the most, powerful production bike ever made, with a speed in excess of 225mph, a redline of 10,500rpm, more than twice the torque of a Triumph Rocket 3, up to 500hp (with race fuel), but weighing just 280kg dry and a wheelbase of 1650mm, no longer than a Ducati Diavel. The bike is expected to cost around £150,000 when launched sometime in 2021.
TV and media
Speed Freaks
His success in Land Speed Racing has led Zef to become a TV presenter/racer with a new 'high octane' TV series called Speed Freaks, a six-episode production on ITV4, produced by Keshet, focusing on Land Speed racing and Speed. This 6 x 60’ series will see daredevil Zef Eisenberg take on his toughest challenge yet - to break the British land speed record in a car he plans to engineer himself. With over 40 land speed records currently to his name, he's already done it on a bike at the iconic Pendine Sands in Wales. Now Zef wants to finish what Sir Malcolm Campbell started in 1927 and break the 200mph barrier in a car and, in doing so, become the only person to hold the British land speed records on both two and four wheels. In order to prepare for this dangerous feat, Zef is scouring the nation to meet fellow motoring mavericks and glean essential engineering know-how from their incredible “franken-machines”.  Whether they've fitted a 24,000cc W12 aero-engine into a car, or built from scratch a full Dakar off-road racer, Zef's going to get behind the wheel and under the bonnet of Britain's fastest cars, bikes and boats. Inspired by these extraordinary machines, Zef will challenge his own team of mechanics to take a different vehicle each week and make it as fast as humanly possible. The knowledge they gain will play a crucial part in helping this real-life Tony Stark and his team prepare Zef's crazy 1200hp specially built road-legal Porsche 911 Turbo S for the series finale - his death-defying record attempt at Pendine Sands. Speed Freaks has been commissioned for ITV4 by Paul Mortimer, Head of Digital Channels and Satmohan Panesar, Commissioning Editor, Factual Entertainment. David Williams, Keshet Productions said, “This high-octane series features a feast of items and VTs geared up to indulge anyone with an interest in cars, motorsports and engineering.  Zef’s need for speed and desire to break that land-speed record is infectious and makes for compelling viewing.” In May 2019, Eisenberg achieved his goal of achieving the fastest ever wheel driven vehicle bike and car at Pendine sands, with speeds in excess of 210mph.
