Terrible experience- I purchased two conversion kits- mine started acting up less than a year after purchase. Took their Customer service department over a month to get with me. Replaced Battery and Control Unit. Now the new unit and my wife unit both start running away on us. When you restart you have nothing until the unit decides it wants to work again. When it runs away the brake lever disconnects do not work, you manually have to reach up and turn the unit off while its speeding down the road. Sorry I ever purchased these kits. I started a new ticket twice on this new problem and its been over two weeks and I haven't heard from them.--Oh I do get about 3 emails a week trying to sell me a conversion kit "ha"
