Heldun were motorcycles produced from 1965 to 1968 in Shropshire.
The company only made 50cc machines, either as complete models or as kits. The list was ambitious and they used German and Italian two- and four-stroke engines, with models for road, road racing and trials in a variety of forms.
By 1967 they had added a scrambler and supplied in kit form only.
By 1968 only one trials model was mentioned, and then the name disappeared.
