Pendle tow ball Discovery 4 bike hang on rack TBMD Strap kit included. Price:   £112.99

Made of stiff, high tensile steel tubing, with a durable powder coated finish to protect bicycle paint. The mounting block has a spherical inner section and bolts to European / swan neck style towballs. Bikes hang (side by side) from upright L shaped horizontal arms, which are held in place by clips. These can be removed when the rack is not in use, though the mounting block would also need removal if you wanted to tow. This rack allows up to 6" offset from the mounting block to give enough clearance around the spare tyre on the smaller 4 x 4s like the Discovery. Straps are included, weight 8.5kg.
