I had a new KT controller fitted to my Wife's Freego Regency bike. I was so impressed with it that I decided to buy myself a Regency and have it converted as well . I bought one in very good condition on Ebay. It arrived with everything ....except the Keys to the back wheel lock. Think they are called Dutch wheel Locks. Seller can't find them. Don't want to send it back as in excellent condition. Any suggestions?
