A great "Thank you" to all those who took the time to reply to my request to help me locate a purchaseable Segway lock kit, especially to those who went to the extra trouble of locating their unused one hidden away.
After all option were weighed up carefully, a Segway dealer was able to provide me with a new kit at the most competitive price and also organise shipment across the Pacific puddle.
Again, my thanks to those who offered their own unused lock kits.
