Sinclair had planned to introduce the [[Sinclair X-1]] through Sinclair Research, another attempt at a personal electric vehicle following the Sinclair C5. The X-1 was first announced in 2010, and incorporated design aspects that the C5 had been panned for, including an open egg-like shell for the rider with a more ergonomic seat, a more powerful motor and larger battery storage, and an effectively lower cost accounting for inflation than the C5.<ref>{{cite magazine | url = https://www.wired.com/2010/11/sinclair-x-1-sir-clive-tries-another-electric-bike/ | title = Sinclair X-1: Sir Clive Tries Another Electric Bike | first=  Charlie | last= Sorrel | date = 5 November 2010 | accessdate = 16 September 2021 | magazine = [[Wired (magazine)|Wired]] }}</ref> However, the X-1 failed to reach the market.<ref>{{Cite news|url=http://www.edn.com/electronics-blogs/benchtalk/4437901/Sir-Clive-Sinclair-interview--ZX-Spectrum-relaunched-for-retro-gameplay|title=Sir Clive Sinclair interview|last=Dunn|first=Michael|date=8 December 2014|newspaper=EDN|access-date=5 February 2017|language=en}}</ref>
