Electric Pedals (London) hires out a Large tier of up to 20 bikes for audiences of 500 or more and a Small tier of 2–6 bikes under the published architecture claim "All electricity is generated live by the riders. No mains power. No stored battery energy." ^1,2 Its 18 kg battery-free "OWL" backpack kit has travelled with conservation and wildlife NGOs across six African countries, from Malawi to Madagascar, including a Malawi roadshow that reached over 14,000 people in six weeks ³.

The market around it is small and specific. Reaction Bike Power's 4–8-bike hire needs no electrical storage at all ⁴; Bespoke Gear supplies 250–500 W generators and has published open, no-welding DIY plans since 2011 that underpin much of the field's grassroots building elsewhere ^5,6; Bent Architect staged a fully human-powered pop-up cinema in Bradford in March 2025 ⁷. Magnificent Revolution, which ran Cycle-In Cinema from the 2007 Big Chill festival with 8- and 20-bike systems, has no activity documented after October 2012; its former domain has been hijacked and now serves gambling spam, so it is not linked from this site ^8,9, and its construction plans survive at the suppliers that carried its lineage forward ^5,6. Across the Irish Sea, Pedalcents ran indoor 8-bike fundraiser screenings behind a 16-by-9-foot screen in 2015 and 2016; its site is still online, but no 2024–2026 activity is documented, so it is listed as uncertain ¹⁰.

Two entries are documents rather than operators. The university reference builds — a Sheffield/Engineers Without Borders single-bike cinema costed at £475 around a 60 W BenQ GP1 projector, and a 2016 Leicester project — are kept as reference designs in active use ¹¹. Low-tech Magazine's 2022 household bike-generator guide carries no map pin because the corpus does not locate the publication, but its instrumented efficiency curve is the only measured generator dataset on record and is cited throughout the site's explainers ¹².
