Although rotary engines were mostly used in aircraft, a few cars and motorcycles were built with rotary engines. Perhaps the first was the [[Millet motorcycle]] of 1892. A famous motorcycle, winning many races, was the [[Megola]], which had a rotary engine inside the front wheel. Another motorcycle with a rotary engine was [[Charles Benjamin Redrup|Charles Redrup]]'s 1912 [[Redrup Radial]], which was a three-cylinder 303&nbsp;cc rotary engine fitted to a number of motorcycles by Redrup.

In 1904 the [[Barry engine]], also designed by Redrup, was built in Wales: a rotating 2-cylinder boxer engine weighing 6.5&nbsp;kg<ref name="Barry">{{cite web |url=http://www.fairdiesel.co.uk/Redrup.html |title=Charles Benjamin Redrup |access-date=2008-04-11 |archive-date=2017-07-15 |archive-url=https://web.archive.org/web/20170715031138/http://www.fairdiesel.co.uk/Redrup.html |url-status=live }}</ref> was mounted inside a motorcycle frame.

The early-1920s German [[Megola]] motorcycle used a five-cylinder rotary engine within its front wheel design.

In the 1940s [[Cyril Pullin]] developed the [[Powerwheel]], a wheel with a rotating [[single-cylinder engine|one-cylinder engine]], [[clutch]] and [[drum brake]] inside the hub, but it never entered production.
