Savage 750 - Rambo Bikes Savage Electric Bicycle

My wife bought the bike directly from Rambo as a gift for me for Christmas. As part of a black Friday deal, the bike came with a high mountain conversion kit, used to increase climbing power, I believe. Perfect! With this included, she thought the price and deal were good, and purchased the package deal. After receiving the bike, I decided to install the kit. Pretty straight forward, not really clear directions, but nothing that could not be figured out.... Once all the pieces were assembled and attached, the last part needed to be done was to attach the chain.. This is where the problem starts. Humm... Upon installing the chain, the new sprocket on the kit and the "old" sprocket on the bike were not compatible. I called Rambo the following day and told them the problem... figuring its an easy switch on a sprocket.. Their answer, "Oh, that kit will not fit on my bike" WTF.. Well, then, how about a refund on the price of the conversion kit? "Nope! We can't do that.. " In our last conversation, they stated to send me my address and they will send me a hat.. Ugh, nope! There will be no advertising. Why send something with a bike that is known not to work or fit. A worthless free gift. I feel it was pretty bad business, and will no longer purchase anything Rambo related.
