Ivy (motorcycles)

Ivy was a motorcycle manufacturer between 1907 and 1934 in Birmingham, England. It was run by various brothers from the Newman family. Ivy built about 6,000 motorcycles of various models. Most used two-stroke engines made by either J.A.P. or Precision, but there were also 225cc and 296cc engines designed and manufactured by Ivy.[1] The company also made its own suspension forks, carburettors and sidecars. The company was heavily involved in motorcycle racing, with several of the Newman brothers entering races themselves. The race bikes were kept as standard wherever possible to demonstrate the build quality and specification of the production machines. The Newman brothers believed that this was the best way to prove their designs and advertise their products. H. C. Newman was especially successful, winning many local events and finishing well in the Isle of Man TT races several times.
