# Talk:Sinclair C5

Someone (or multiple people maybe) keep adding a link to their forum to this site, using advert like text. There is no need for this link to be here, and the owners of the site and users of the site make money selling parts though it. How would one go about getting this site blocked? Is it even to the point where it should be? 88.211.96.3 (talk) 14:36, 22 October 2008 (UTC)

I think that the Jet-powered C5 is spoof.--Timtak (talk) 15:53, 31 October 2008 (UTC)

c5alive.co.uk is another c5 enthusiasts website which also has a forum , and yes, spares are bought and sold to help keep the things running. The c5's are all nearly 25 years old now and need some help to keep them running. So why not include links to such sites ?

Had a C-5 "car" tough plastic somone took a sledge hammer to it only the taillight was damed! Also thinks theres a new Eletric scooter Car called the "NIKOLA" coming out soon based on the c-5(after NIKOLA Tesla Teslaedsonmoi (talk) 01:49, 30 July 2010 (UTC)

I spent the early eighties building all the Sinclair prototypes for the C5. As there were four of them (all different)and the resulting production model was called C5 I suppose you could say mine were the C1, C2, C3, and C4 (though that's not official of course).
The other day I was tidying my garage and came across an eighth-scale model of the C4 which I had made for wind-tunnel testing at Exeter University. The project was moved from me to Lotus Cars for 'sorting and productionising' some time in 1983 and I seem to remember that the idea was to have them built in the defunct DeLorean factory in Ireland (by robots apparently) but we all know that the C5s ended up being assembled alongside washing machines at Hoover. I should point out that I only produced the bodies and that the mechanical engineering was carried out by a firm based at Exeter Airport. Rotorbloke (talk) 19:45, 11 December 2010 (UTC)

Although I just added a cite (and correction) to the previously un-referenced "12,000 units" sales figures, the 17,000 overall units sold figure provided by Sinclair Research might be also doubtful, since Sir Clive was quoted by the BBC in 2003 as saying "we sold 5,000 of them".BBC News 
Perhaps some diligent digging (maybe via Hoover Company records or annual reports) will uncover some good sales figures from that era. — DennisDallas (talk) 16:46, 18 July 2011 (UTC) & 16:48, 18 July 2011 (UTC)

Who designed Sinclair C5? Rick Dickinson?  — Preceding unsigned comment added by 188.83.10.244 (talk) 19:07, 19 March 2012 (UTC) 

No, he only did the ZX80, ZX81 and the original Spectrum. The C5 was designed by Tony Woods Rogers (who built the prototypes) and Guy Desbarats, who did the industrial design. Prioryman (talk) 19:17, 19 March 2012 (UTC)

This review is transcluded from Talk:Sinclair C5/GA1. The edit link for this section can be used to add comments to the review.
Reviewer: Ritchie333 (talk · contribs) 14:38, 19 September 2014 (UTC)

Like the ZX81 and the ZX Spectrum, this gives me nostalgia for the 1980s. The article has 61K of prose, which suits a lead of three paragraphs.
All of the online references check out okay. The biggest problem at the moment are the references, which need to have a fuller list of where to find the books. I presume "Dale" is "The Sinclair Story" by Rodney Dale, but we'll need the full title, publisher and ISBN to ensure the information cited to it is factually accurate and verifiable. Usually, I split references into "Citations" (where the {{reflist}} template goes) and "Sources" (where individual book entries appear).
Further comments to follow. Ritchie333 (talk) (cont) 14:38, 19 September 2014 (UTC)


### Lead
The quotations in the lead don't appear to be in the body. Either they need to be duplicated and expanded, summarized or removed.
I've tackled this now - they're now reflected in the "Demise" section. Prioryman (talk) 18:07, 27 September 2014 (UTC)
"Sinclair had made a fortune" - possibly "Sinclair had been financially successful" would be better
I've addressed this by explaining that Sinclair had become a multimillionaire from his computer business and hoped to repeat that success with electric vehicles, which I think puts it in context better.
"It was launched" - what was launched?
Reworded. Prioryman (talk) 18:07, 27 September 2014 (UTC)


### Design
The citation for the first sentence in this section needs more information. I assume this was a press release. Do we have an ISSN or similar for it?
No, it's from the C5 promotional brochure (of which I have a copy). No ISSN. Prioryman (talk) 19:32, 22 September 2014 (UTC)
"The chassis consists of a single Y-shaped steel member" - can you clarify what "member" means in this instance?
"in cross-section" sounds a bit awkward", perhaps "has a cross-section of" followed by the dimensions
I've addressed the above two points by rewording as "a single Y-shaped steel component with a cross-section ..." Prioryman (talk)
What are "power toggles"?
Reworded as "A power switch and front and rear brake levers are positioned on the handlebar." Prioryman (talk) 19:32, 22 September 2014 (UTC)
"revolutions per minute" should be defined on first use
Done. Prioryman (talk) 19:32, 22 September 2014 (UTC)
The citation in the last sentence for the last paragraph is a little vague - can this be tightened up, particularly as there is a direct quotation, and referral to the "High-Vis Mast" I recall Crash had a special feature on the C5 (and scans of the magazine are available online) where they talked about the "Hi-Vis Mast".
It's from a different promotional brochure (again, I have a copy) that Sinclair shipped with each C5. I've clarified the reference. Prioryman (talk) 19:32, 22 September 2014 (UTC)


### History
#### Origins
"while he was still a teenager" - "as a teenager"
"in the late 1950s" ... "fifteen years later" ... "in the early 1970s" - the narrative seems to jump around a bit
Reworded these. Prioryman (talk) 19:39, 22 September 2014 (UTC)


#### Early development
"a preliminary investigation into a personal electric vehicle" - best to put a direct citation after a quote
Done. Prioryman (talk) 22:09, 23 September 2014 (UTC)
" It would be aimed at" - wouldn't "It was aimed at" be better (given the specification, which was completed, is what is being referred to)
Reworded. Prioryman (talk) 22:09, 23 September 2014 (UTC)
"It would be easy to drive, park and enter or exit" - enter or exit where exactly?
Enter or exit the vehicle. I've made this clearer. Prioryman (talk) 22:09, 23 September 2014 (UTC)
"costing £500 at the most" - is it worth putting in a conversion figure to show how much that is today?
Hmm. I'm not a fan of doing that, given the different ways of measuring values over time. Prioryman (talk) 22:09, 23 September 2014 (UTC)
I still think it would be helpful. A typical reader may not have been born when the C5 was introduced, and hence might have no concept of the practical worth of £500 in 1985. Ritchie333 (talk) (cont) 12:11, 25 September 2014 (UTC)
"Sinclair chose to rely on existing lead-acid battery technology, avoiding the great expense of developing a more efficient type of battery" - don't need the "of battery" at the end, we know the whole sentence is talking about that
Good point, done. Prioryman (talk) 22:09, 23 September 2014 (UTC)
"Tony Wood Rogers recalls" (before the quotation about battery choice) should be simply "Wood Rogers" per WP:LASTNAME, and shouldn't it be "recalled"?
Changed the name, but I think "recalls" is the proper style in the context. I'll look into this point. Prioryman (talk) 22:09, 23 September 2014 (UTC)
"Sinclair head-hunted Barrie Wills" - "employed" is probably simpler
Reworded. Prioryman (talk) 22:09, 23 September 2014 (UTC)
"established in Warwick in the West Midlands" - the problem here is that there is West Midlands (county), which was existent during the C5's lifetime, but Warwick was never in. Not sure what to do about this.
It's not a problem really, it refers to the West Midlands (region) in which Warwick is most definitely located. Prioryman (talk) 22:09, 23 September 2014 (UTC)
"in an area with" - don't need "in"
Reworded. Prioryman (talk) 22:09, 23 September 2014 (UTC)
It would be helpful to give a brief overview of why VED was abolished for electric vehicles in 1980.
I have to admit I don't know. I'll have to do a bit more research on this. Prioryman (talk) 22:09, 23 September 2014 (UTC)
Raleigh redirects to Raleigh, North Carolina. You want Raleigh Bicycle Company
Already fixed by someone else, it seems. Prioryman (talk) 22:09, 23 September 2014 (UTC)


#### Development and design of the C5
What are the "A, B, C1 and C2 demographic groups"?
I've added an explanatory link. Prioryman (talk) 13:10, 25 September 2014 (UTC)
"one of the first such tests carried out on 29 July 1981" - how is this possible given that we've just been told that prototypes weren't available until late 1983?
Very good point, I can only think that this is a mistake by the cited author. I've removed it. Prioryman (talk) 13:10, 25 September 2014 (UTC)
Are you sure the name is "High-Vis Mast", not "Hi-Vis Mast"?
Yes - that's how it's spelled in the Sinclair brochures. Prioryman (talk) 13:10, 25 September 2014 (UTC)
"It was claimed" - per WP:CLAIM, say who specifically said this
Attributed. Prioryman (talk) 13:10, 25 September 2014 (UTC)
Worth linking "jig" to jig (tool)?
Done. Prioryman (talk) 13:10, 25 September 2014 (UTC)
Shouldn't British Leyland Maestro be Austin Maestro
Yes, amended. Prioryman (talk) 13:10, 25 September 2014 (UTC)
"and took only about 70 seconds" - suggest "and only took about 70 seconds to complete"
Amended. Prioryman (talk) 13:10, 25 September 2014 (UTC)
Worth mentioning that the suggested DeLorean factory was in Belfast?
No harm in it, done. (Actually Dunmurry). Prioryman (talk) 13:10, 25 September 2014 (UTC)
The WDA quotation needs a source
Already cited actually, but I've made this clearer. Prioryman (talk) 13:10, 25 September 2014 (UTC)


#### Production, distribution and support
" Hayes, Middlesex, Preston in Lancashire" - inconsistency between using comma and "in"
Fixed. Prioryman (talk) 13:12, 25 September 2014 (UTC)
"The C5's major consumable item, the battery, was to be supported by 300 branches of Comet and Woolworths." - this sentence is unsourced
Now cited. Prioryman (talk) 13:12, 25 September 2014 (UTC)


#### Launch
The C5 was launched on a cold, snowy Friday 10 January 1985" - though the weather was believed to contribute to the negative impression left by the launch, I don't think "cold, snowy" belongs up front here
OK, trimmed. Prioryman (talk) 13:18, 25 September 2014 (UTC)
"The event was typically glitzy" - typically of what?
I've reworded this. I was aiming to say that it was in Sinclair's usual style. Prioryman (talk) 13:18, 25 September 2014 (UTC)
The large quotation from the sales brochure in the third paragraph looks a bit too large and may invite accusations of close paraphrasing.
I've trimmed this. As a nit-pick though, surely it can't be "close paraphrasing" if it's a direct quotation? Prioryman (talk) 13:18, 25 September 2014 (UTC)
Could we explain who Ian Adamson and Richard Kennedy are?
Done. Prioryman (talk) 13:18, 25 September 2014 (UTC)
"but this proved, as Adamson and Kennedy put it, "an unqualified disaster"" - missing a verb, should be "but this proved to be"
Added. Prioryman (talk) 13:18, 25 September 2014 (UTC)
The Sunday Times and The Guardian should be wikilinked, non UK readers might not be familiar with them
Good point, done. Prioryman (talk) 13:18, 25 September 2014 (UTC)
The Your Computer source is mistakenly attributed to Your Sinclair
Oops, fixed. Prioryman (talk) 13:18, 25 September 2014 (UTC)
The last sentence in this section is unsourced, and seems to be more of a linking narrative. The best solution would be to move it to the top of the next section.
OK, I'll find a home for this elsewhere. Prioryman (talk) 13:18, 25 September 2014 (UTC)


#### Reactions
Not sure about this section title. "Response" or "Reviews" might be a better choice
"Reviews" works best, I think. Prioryman (talk) 13:23, 25 September 2014 (UTC)
British Safety Council should be linked and labelled (BSC) so we know that that acronym's referring to that
Done. Prioryman (talk) 13:23, 25 September 2014 (UTC)
"The verdict from motoring organisations, road safety groups and consumer watchdogs was decidedly negative and probably sealed the C5's fate." But the only response given was from the BSC. The responses from the AA and Which could be moved here.
The source quoting James Tye (United Press International) could do with more information. If this is a press release, using {{cite press release}} rather than {{cite news}} might be a better fit
United Press International is a press agency like Reuters or Associated Press and the citation is of a news report, so the news template is appropriate. Prioryman (talk) 13:23, 25 September 2014 (UTC)


#### Sales history
"Princes William and Harry", and Paul Daniels could do with the appropriate links.
Done. Prioryman (talk) 13:27, 25 September 2014 (UTC)
The section about notable owners may need to be investigated. I don't believe Prince Harry would have been physically capable of driving a C5 throughout its original sales life, when he would have been less than one year old. I got the impression from reading The Scotsman source that the princes picked up second hand models years later when they were adults.
The source doesn't say this explicitly, though it would be a reasonable assumption. I've tweaked the wording of the first sentence of that para to make it clear that it refers to owners rather than necessarily meaning buyers of the first tranche of C5s on sale. Since we don't know exactly when they acquired their C5s we can't say either way. Prioryman (talk) 13:27, 25 September 2014 (UTC)
Is the Honda PX50 notable enough for a redlink?
Not sure to be honest, I'm not particularly knowledgeable about mopeds. Maybe leave it as it is, and if someone else wants to add a link they can? Prioryman (talk) 13:27, 25 September 2014 (UTC)
The Financial Times source for vehicle theft needs a page number
Added. Prioryman (talk) 07:26, 26 September 2014 (UTC)
"sales of the C5 remained in the doldrums" - this sounds like a colloquialism, how about simply "sales of the C5 remained weak"
Reworded. Prioryman (talk) 07:26, 26 September 2014 (UTC)


#### Demise of Sinclair Vehicles
"what Rodney Dale calls" - per WP:LASTNAME, this should be simply "Dale"
Amended. Prioryman (talk) 07:38, 26 September 2014 (UTC)
The Sunday Times source for 15 December 1985 needs a page number
Unfortunately I don't have it - I had a press cutting that gives the date but not the page number. Prioryman (talk) 07:38, 26 September 2014 (UTC)
Do we know when Ellar resold the remaining C5s. The Daily Mail source given is dated 1996, nearly a decade later. The source also needs an author (if available) and page number
They bought them in 1985 and presumably sold them over a number of years - I don't know how many. There is no named source for the Daily Mail story (presumably a staff reporter) and as with the Sunday Times story, it was a press cutting with a date but not a page number. Prioryman (talk) 07:38, 26 September 2014 (UTC)
Why is Andrew P. Marks' view particularly important? The quotations are a little overlong, similar to above
I've trimmed the quotations. His views are significant as an academic analysis (published in an academic (peer-reviewed?) journal) on the reasons for the C5's failure. He's the only author I've seen addressing the C5 in detail in the academic literature. Prioryman (talk) 07:38, 26 September 2014 (UTC)
Who are Nigel Cross and Gus Desbarats? These opinions (as with Marks) would sit better in the "Legacy" section as they're not specifically anything to do with the demise of Sinclair Vehicles itself
I've clarified these. I don't think they work so well in "Legacy" as they specifically address what caused the failure of the C5 and by extension, Sinclair Vehicles. "Legacy" is what happened after Sinclair Vehicles failed. It seems logical to me to include an analysis of the C5's failure before that point. Prioryman (talk) 07:38, 26 September 2014 (UTC)


### Legacy
"Barrie Wills", per WP:LASTNAME should be "Wills". Likewise, "Tony Wood Rogers" should be "Wood Rogers"
Done. Prioryman (talk) 07:45, 26 September 2014 (UTC)
Can you confirm the Toyota Prius source specifically refers back to the C5?
Yes, it does. Prioryman (talk) 07:45, 26 September 2014 (UTC)


### External links
Can you give a brief description to each of the owner's clubs?
Done. Prioryman (talk) 18:08, 27 September 2014 (UTC)


### Summary
Overall, this is a well written introduction to a particularly idiosyncratic piece of British engineering. Though I've been aware of the C5 ever since it came out, I've never actually seen one myself, much less driven one. Anyway, I'll put the review on hold pending resolution of the above issues. Ritchie333 (talk) (cont) 10:34, 22 September 2014 (UTC)
Okay, I think we're mostly there apart from the concerns in the lead. Once the few remaining issues are left, I can pass this. Ritchie333 (talk) (cont) 17:38, 27 September 2014 (UTC)
@Ritchie333: Thanks for all your help with this. I've tackled the lead, so I think that's probably the lot now. Prioryman (talk) 18:09, 27 September 2014 (UTC)
Okay. The citation format is a little unusual, but that's not part of the GA criteria, so I can now pass this. Well done. Ritchie333 (talk) (cont) 18:40, 27 September 2014 (UTC)

The vehicle's battery is designed to provide 35 amps per hour when fully charged
is a direct quote from the source, but it doesn't make a lot of sense. What is meant is that a charged battery can supply 35 amps for one hour (and is then flat). 109.145.108.156 (talk) 22:30, 22 June 2016 (UTC)

A bit late, but it is clear that the original quoted source is a typo (or, more likely, some non techo copywriter thought that the correct version was a typo).
"35 Amps per hour" should have read "35 Ampere hours". 2A00:23C8:9883:A001:2DB6:A14C:7AD2:2F40 (talk) 15:49, 19 December 2024 (UTC)

I noticed this on the BBC News site this morning: http://www.bbc.co.uk/news/business-38960275
(Clive Sinclair's nephew is trying to create a modern equivalent to the C5).  — Preceding unsigned comment added by Shasarak (talk • contribs) 09:42, 15 February 2017 (UTC) 

I added it (with a few more sources). It can be expanded if needed with info from the different sources. // Liftarn (talk) 08:52, 20 February 2017 (UTC)
