• Constructed of super tough - water resistant 420 D Nylon • Covers up to 2 bikes • Not to be used on the back of a vehicle . The main issue is wind, putting the RV bag on the back of a regular vehicle (non-rv) subjects it to an excessive force from the wind, which will likely tear/shred the bag, but also puts an undue load on the bike rack and the bikes which can lead to the rack failing or damage to the bikes. • Ensure that bike and covers are clear of exhaust pipes and that the cover can not get caught in any moving parts on the vehicle. The Swagman Horizontal RV bike carrier cover is new and improved to allow for wider handle bars and larger hitch mount racks, giving you the space you need for any large sized heavy duty ebike and cruiser. Fitting up to two bikes this is the perfect accessory for both families and men and women who enjoy traveling by RV or use a travel trailer. The large zippered opening makes it easy to cover your bikes without the extra hassle and the straps secure it for less flapping. The weather resistant nylon material is durable enough to tow your bike on the back of an RV, but is not suited for travel on the rear of SUV, cars, and regular vehicles that are subject to high winds. "Ride, paddle, explore: seek your adventure" That philosophy was the intention of founders Jim and Jan Morris who saw an opportunity to create a better way to transport your bike back in the early 90’s. Swagman was one of the first companies worldwide to design and market a hitch style bike rack. Over the years, that small bike rack company based in the Okanagan Valley of British Columbia grew to include numerous other ground breaking designs in the North American Bicycle, RV and Automobile markets.
