The information source for single wheel trailers from the early 1900's, through today, Allstate and Heilite to name a couple. The intention of this site is to be the most comprehensive, informational single wheel trailer site on the internet. If you have any information, pictures, or anything else send us an email.

A. Sommer

Manufactured in Germany by the A. Sommer company. The trailer could be purchased in the early to mid 1960’s for 350 DM (around $205). It appears as though this trailer will fold and rest up on the back of the tow vehicle similar to the Huckepack made by Calberlah, another German trailer.

Here I send you some pictures of my single wheel-trailer. Sorry but I don’t have any more information of it. I’m also just waiting for information form someone in Germany who told me he also owns a singlewheel-trailer of “Sommer”. When I get theses information I will send them to you. Owned by Christoph Weyers.
