The Sinclair C5 electric vehicle is back as the X-1!

The Sinclair electric vehicle is back!

Sir Clive Sinclair’s first stab at cheap, clean personal transport, the Sinclair C5 which was released 25 years ago, was so far ahead of its time that it was met with ridicule and proved a huge commercial flop .

However, the British inventor of the ZX80, ZX81 and ZX Spectrum computers is back with a new electric vehicle concept, the new Sinclair X-1.

Like its predecessor, it’s powered by a mix of battery and human elbow grease, with its lightweight rechargeable 24v Lithium Polymer battery pack claiming to serve up to 10 miles travel for just 10-pence-worth of electricity.

No licence required

The X-1 is powered by a ‘super efficient’ MCR pancake 190 watt motor, linked to the rear 16″ wheel by a fixed gear drive chain –  and because it’s classified as a bike, can be driven by anyone over the age of 14, and without a licence, insurance or road tax

Enclosed in an acrylic bubble with an integral roll cage frame bonded to monocoque chassis, and backed by front and rear disc brakes and lights, the X-1 hopes to persuade people that it’s a far safer proposition than Sinclair’s first wobbly effort.

The Sinclair Research X-1 is expected to go on sale in July 2011 for £595. UK residents may be eligible to get a 50 per cent reduction under the Government’s Cycle to Work scheme.

  1. The Sinclair C5 had three wheels and wasn’t a bicycle. This is an electric bicycle with a roof on it. Completely different.

  2. Make the C5 more agile. Add a roof. Add indicators. New and improved design done.

    To me this just looks like an incredibly unstable bike
