I have a Saris Freedom Hitch rack and tried it on my new 500 ST yesterday. It almost worked! The rack has a middle stem that has a brace for the downtube but the ratchet strap is too short to fit around the battery and the tube. Saris does sell some longer straps, but they seem to be out of stock. Ebay only seems to sell regular-size strap replacements. Are these something I could find elsewhere? Or somehow strap it some other way? Also, the Saris requires quite a lift to get the 55+ lb bike onto the rack. Is there a better way? Thanks.
