The writing credit on the single is Robert Calvert and Sylvia MacManus.[1] MacManus was Dave Brock’s then wife Sylvia whose name Brock used in order to put pressure on his publishing company to improve his deal.[2] The verse is an eight-bar rock and roll boogie whose riff is an adaption of the standard riff that can be heard on the likes of Johnny and the Hurricanes' "Red River Rock" (sample ).

[The Greasy Truckers] was about my third gig, and I didn't know what I was doing. I hadn't done any rehearsals and I thought that Silver Machine was a Chuck Berry number – really. – Simon King[3]

The lyrics were written by Robert Calvert and he sang the lead vocal on the original live recording. However, the vocals were considered too weak (sample ) for the single release so they were re-recorded in the studio. Calvert, who suffered from bi-polar disorder, had been sectioned at the time so was unavailable to attempt another version, and the lead vocals were eventually recorded by Lemmy:

[Calvert's] vocal was fucking hopeless, but he never realised it. That's how mad he was. It sounded like Captain Kirk reading 'Blowing in the Wind'. They tried everybody singing it except me. Then, as a last shot, Douglas said, 'Try Lemmy'. And I did it in one take or two.[4]

Lemmy just had the best voice for it. Of course, Bob was not pleased when he found out. – Douglas Smith[5]

The lyrics are a send-up of space travel, inspired by the Alfred Jarry essay How to Construct a Time Machine which Calvert interpreted as a description of how to build a bicycle:

I read this essay by Alfred Jarrey [sic] called, "How to Construct a Time Machine", and I noticed something which I don't think anyone else has thought of because I've never seen any criticism of the piece to suggest this. I seemed to suss out immediately that what he was describing was his bicycle. He did have that turn of mind. He was the kind of bloke who'd think it was a good joke to write this very informed sounding piece, full of really good physics (and it has got some proper physics in it), describing how to build a time machine, which is actually about how to build a bicycle, buried under this smoke-screen of physics that sounds authentic. Jarrey got into doing this thing called 'Petaphysics' [sic], which is a sort of French joke science. A lot of notable French intellectuals formed an academy around the basic idea of coming up with theories to explain the exceptions to the Laws of the Universe, people like Ionesco the playwright. The College of Metaphysics. I thought it was a great idea for a song. At that time there were a lot of songs about space travel, and it was the time when NASA was actually, really doing it. They'd put a man on the moon and were planning to put parking lots and hamburger stalls and everything up there. I thought that it was about time to come up with a song that actually sent this all up, which was 'Silver Machine'. 'Silver Machine' was just to say, I've got a silver bicycle, and nobody got it. I didn't think they would. I thought that what they would think we were singing about some sort of cosmic space travel machine. I did actually have a silver racing bike when I was a boy. I've got one now, in fact. – Robert Calvert[6]

Hawkwind have very rarely appeared on television, but the success of the single necessitated an appearance on the BBC chart show Top of the Pops. However, the group felt ill at ease at the prospect of miming a performance in front of a studio audience who didn't represent their following, so a compromise was reached with the BBC recording the band performing live at Dunstable Civic Hall on 7 July 1972, this clip being shown with the single version dubbed over it.

A version was recorded at Maida Vale Studios, London on 2 August 1972 for broadcast on the Johnnie Walker show on the 14th, "Brainstorm" also being part of the session. These two recordings have subsequently been included on the 2010 EMI release Hawkwind: At the BBC – 1972.[18] The song was also recorded live at the Paris Cinema, London on 28 September 1972 as part of the hour-long In Concert series broadcast. This full concert was released in mono in 1991 as BBC Radio 1 Live in Concert, and in mono and stereo in 2010 as Hawkwind: At the BBC – 1972.[18]

On 3 December 2007, Cleopatra Records in the USA issued a limited edition of 500 10-inch vinyl EPs consisting of both BBC versions of "Silver Machine", the live version as the A-side and the session version as the B-side.

On 14 November 2019, the group recorded a session for Marc Riley's BBC Radio 6 Music show, playing "65 Million Years Ago", "Last Man on Earth", "Spirit of the Age" and "Silver Machine".[19]

The song has sporadically been played live by the band. Its first re-appearance is on the 1980 live album Live Seventy Nine, but it explodes after a minute and is suffixed with "(requiem)" in Brock's attempt at laying the song to rest, sick of having to play their "hit single". Further live versions have been released, most notably a version on the 2002 live album Canterbury Fayre 2001 with vocals by Arthur Brown.

Lemmy continued to make guests appearances with the band when their paths crossed. Some live versions of the song on which Lemmy appeared include The Friday Rock Show Sessions from the Reading Festival 24 August 1986 and Motörhead's Stone Deaf Forever! boxset from Wembley Arena 19 October 2002.

In 1982, the band recorded a new studio version of the song which received general release on 7-inch record and 7-inch picture disk by RCA/Active (RCA267, 27 August 1982). The B-side was a 33 RPM extended play featuring the full 7:25 version and a new version of "Psychedelic Warlords" with a Huw Lloyd-Langton vocal.

Receiving criticism over the release, Brock defended their actions: "It was only done as a tenth anniversary thing, and wasn't supposed to come out just as a picture disc. That was RCA's decision, and I didn't like it one bit. The only reason we cut it was as a special souvenir."[20]

In addition to the single release, the record company included it on the Choose Your Masques album, leaving Marion Lloyd-Langton to complain: "[Huw and I] actually had three tracks for the Masques album, but RCA insisted that Silver Machine went on, so the third track was dropped; pity about that."[21]
