Tannus Tyres (UK) – Tannus is to supply tyres for the ground-breaking IRIS eTrike. “The airless, no-puncture, tyre company stood out as the obvious choice for Sir Clive Sinclair’s nephew Grant Sinclair, who has developed the ground-breaking machine. Tannus were picked because its innovative design performed well on the bike”, shared Tannus Tyres.

The tyres also get round the need for easily removable wheels on the IRIS in the event of flats.

Jazz Walia, Tannus European Managing Director said: “It is fantastic to be able to work with Grant and the IRIS eTrike. It’s a great marriage of two highly innovative products which are challenging conventional wisdom to improve travel in the 21st Century.”

Grant Sinclair said: “We have looked at a number of tyre options and Tannus offer the best solution for the IRIS. Tannus are like us – we are both working to break down conventional barriers and offer a positive future through innovative and ecological consumer products.”

The IRIS will be equipped with one 26 inch Tannus rear wheel and two 20 inch front wheels.

It is the latest in a number of deals struck by Tannus which include supplying tyres to Specialized and 160,000 Chacle Bikes in Japan, and new deals with Alton Sports in Korea and US start up Ezra.

The futuristic eTrike has been compared to the Sinclair C5 launched by Sir Clive Sinclair (inventor of the World’s best selling computer: the ‘ZX Spectrum’ throughout the 1980s).

But while there may be minor superficial similarities between the two trikes, the differences are far greater. The IRIS is a motor-assisted eTrike and not solely electric. Its structure means it has plenty of room for storage and may appeal to delivery businesses, like couriers or fast food companies or even paramedics.

Its outer shell is made of expanded polypropylene which has outstanding energy absorption and multiple impact resistance. It is also fully weather proof.

The IRIS has 8-speed race bike gearing, together with a 250 watt pedal assist motor (more powerful versions are availavle for other territories) and is capable of 30 mph.

It has a lithium battery which is good for 30 miles and can be fully charged in one hour.
