I wouldn't. It's got a 293 cc 2-stroke according to the link. Hopefully, if one must pedal at all, it would be just to start it. Unless you're out of gas. Then you'd also be out of luck. And you get to find out if eating Wheaties pays off.
Wasn't it 1956 and the Reliant Regal Mk3?The Daimler Dart was probably the first British 4 wheeler, but I don't know about three wheelers. Wiki on Reliant fails to give a date for full body manufacture:

However, Glasspar seems to have been the first production (though not necessarily mass production) glassfibre car:

-----------Wasn't it 1956 and the Reliant Regal Mk3?
---------------------------No, no charm at all. It's a shed.
-------------------------------The Allard Clipper. 1 x door, 1 x bench seat. 1 x wheel drive. Dickie seat behind cabin to safely isolate 2 loud and sticky children.
----------------------------There are many claims and counter claims about who made the first series production fibreglass cars (yes, it's a loose term here), but the Allard dates from 1954, so that's one marker down.
----------------------------------------------Yes exactly, it's why I dislike the things too
