US company Sidewinder Campers has developed hard-shell living modules that attach to the side of a motorcycle in sidecar fashion rather than being towed behind. Four versions are offered: Pygmy, Colorado, Mojave and Sonoran. The smallest, Pygmy, measures 2.13 m long and 1.22 m wide and high, weighs about 159 kg unladen and sleeps two. The Sonoran is nearly 4 m long, weighs 612 kg and is designed for four people. The modules are compatible with cruiser, adventure and touring motorcycles with engines of 1000cc or more. Pricing for the Pygmy has not been announced; some sources put the starting price at about 10,000 US dollars. The Autopian raised safety concerns: the wide module on the right restricts the rider's view, and the Sonoran's weight exceeds typical towing guidelines for motorcycles.
