First this is a project that requires some experience with bicycle repair and terms used. The Rear wheel Conversions are more complicated than the front wheel ones. You will need a set of Metric Wrenches and a set of Metric Hex Keys. The manual that comes with the kit is well illustrated but it assumes you are familiar with bicycle repair. You will be using your existing Tire, Tube and Freewheel. The instructions DONOT say "take a 3/4" hexhead screw etc etc". You are given a complete bag of hardware and you are on your own to decide what fasteners to use. You will be required to remove the right front Shifter and right front Brake to install the Throttle. After the conversion is complete it is recommended that you ride the bike around to check your shifting and brakes, all should function normally, if not adjust brakes and rear deraileur before installing battery and applying electric power. Check front and rear tire pressure to be sure they are up to spec(written on the sidewall of the tires). You now have the option to pedal as before or get the bike moving and hit the throttle. Some links to help you out.
CURRIE TECHNOLOGIES for the rear wheel conversion kit, They also have kits for the front wheel that are alot easier to install.--PARKTOOL For howto and bicycle tools--SHELDON BROWN about freewheels and how to. A freewheel is that multigeared disk on the rear wheel. During conversion it has to be removed from your rear rim and installed on the provided rim and motor combo.
