  But nearly 35 years ago, inventor Sir Clive Sinclair was working on a vehicle that would be right at home in today’s mobility movement. The Sinclair C5 was a single-seat, pedal-assisted electric vehicle that was designed for city commutes. The diminutive car was designed to go up to 20 miles on a charge (though real world numbers were closer.   After a change in the law prompted by lobbying from bicycle manufacturers, Sinclair developed the C5 as an electrically powered tricycle with .

  The infamous Sinclair C5 has inspired a new one-person electric vehicle designed by the nephew of C5 inventor Sir Clive Sinclair. Known as the Iris e-Trike, Grant Sinclair’s creation has a streamlined shape based on the aerodynamic helmets used in track cycling and skiing. It’s constructed from a chromoly steel trike chassis inside a monocoque [ ]. The vehicle is battery-assisted tricycle – like an electric bike these days – the driver pedals it around, but the pedalling is assisted by an electric motor. Though the driver need not pedal (if he’s feeling lazy). The C5 is steered by a handlebar beneath the driver's knees.

  That all keeps it within the EU rules for pedal-assisted e-bike so gets a motor limit at 25km/h. Additional braking for the 55kg e-trike is handled by a pair of hydraulic disc brakes. Step up to the £ Iris eTrike Extreme and you get a W mid-drive motor mounted to the cranks. The Sinclair C5 is a one-person, electric battery assisted pedal cycle. It was the brainchild of Sir Clive Sinclair, one of the UK’s best-known millionaires who had earned a knighthood as a result of his highly successful Sinclair Research range of home computers in the early s.

The classification of the C5 as being an electrically power assisted tricycle suggests that it is appropriate to consider whether its accident performance is likely to be better or worse than that of pedal cycles.

The pedal cycle fatal user casualty rate is per. The Sinclair C5 has been designed to meet the new regulations which eased the legal operating requirements for electrically assisted pedal bicycles and tricycles.

The present report discusses an assessment of the likely accident rate for the C5 on public roads and attempts to relate this to the rate for pedal cycles. Get this from a library.

Sinclair C5: Electric assisted pedal tricycle of the Eighties In the last chapter of our history of ebikes we were in the 70s, with its austerity. With the Yom Kippur war first and the energy crisis from onwards, oil producing countries impose a huge increase in crude oil prices.

The Sinclair C5 is reborn: s electric tricycle gets 21st century update from inventor's nephew Save The Iris E-Trike will cost £3, and up Credit: Grant Sinclair. The new street-legal, one-person hybrid electric/pedal-powered tricycle is billed as faster and safer than its '80s predecessor and sports a Plexiglas canopy, so it can be used in all weathers.

When the motor proved inadequate, drivers could use the foot pedals to propel the vehicle – and it was an “electrically assisted pedal cycle”, the C5 was exempt from tax and insurance. The C5 electric tricycle (with pedal assist) was a single-seater vehicle unveiled with great fanfare on 10 January It was billed as the future of transport.

Sinclair C5 electric trike goes on sale – archive, 11 January The battery–powered tricycle developed by British inventor Clive Sinclair.

A standard powered 12V C5 is therfore still road legal. If you up the voltage to 24V (Or More) you are strictly speaking breaking the law if you take it on a public road as your top speed is over 15mph, and you are effectively doubling the power rating of the motor. It then breaks the Electric Assisted Pedal Cycle rules (EAPC).

In the electrical and electronic aspects of the vehicle, as in most other areas, minimization of component and. Sinclair is widely known for its C5 pedal/electric three-wheeler, which was designed by company founder and pioneering inventor of the ZX range of computers, Sir Clive Sinclair.

The mids. The Sinclair Research C5 is a battery electric vehicle invented by Sir Clive Sinclair and launched by Sinclair Vehicles Ltd in the United Kingdom on 10 January The vehicle is a battery-assisted tricycle steered by a handlebar beneath the driver’s knees.

Powered operation is possible making it unnecessary for the driver to pedal. The Sinclair C5 is a small one-person battery electric velomobile, technically an "electrically assisted pedal cycle". It was the culmination of Sir Clive Sinclair's long-running interest in electric vehicles. Although widely described as an "electric car", Sinclair characterised it as a "vehicle, not a car".

Sinclair had become one of the UK's best-known millionaires, and earned a knighthood. Sinclair was in the mood for more electric vehicle creation inwhen the Zike electric bike was released. Like the C5, production lasted just six months – and around 2, were sold.

The Sinclair C5 was once touted as the future of electric vehicles – and indeed travel. To give you an idea of what we’re talking about, take a look at this original advert from for the.

The Sinclair C5 was billed as the future of transport, writes Jack Stewart for BBC Futures. It was a single-seat "e-trike" that could be driven, or pedaled, by anyone. The advertising buy was big. The ancient UK law which restricted the original Sinclair C5 of the s to watts and 12mph was ignored for many years in favour of the EU limits of watts of continuous power and assistance up to 25kph(mph).

Revised EU regs for ‘electrically assisted pedal cycles’ (EAPCs) were finally integrated with UK law in Januarythe. The Sinclair C5 is a small one-person battery electric velomobile, technically an "electrically assisted pedal cycle".

Derided by many as a national joke when first built in Merthyr 30 years ago, some say the Sinclair C5 electric vehicle still shows the possibilities of transport in the future.
