Hello, Beesley.

I just purchased the kit your looking at from Papamotors. See my developing thread at: http://www.bikeforums.net/showthread...onversion-kits

I had to upgrade my old Trek 820 to a 2012 Kona Lanai to get disc brakes and other structural improvements. The Papamotors kit seems to work better with older bikes which have separate shifters and brakes. Take a look at their online manual and pay close attention to the model of bike they preform the conversion on. As Robert C. mentioned earlier, ebike.ca will help you tremendously as they have helped me. You may be better off purchasing the components through them and getting the battery you need through Ping (http://www.pingbattery.com). I don't think you'll be able to stay within the $1,000 limit but you'll be close. I've already exceeded my limit.
