I just managed to sell my Electra (not electric) cruiser for $225 (£182). I paid $564 (£458 including tax) for it, then added $50 (£40) fenders. Also put a new crank set and freewheel on it because the Megarange freewheel it came with was intended for mountain bikes. A new crankset because the chain ring and crank arm were one piece; I needed a smaller chain ring.
Had 186 people look at it. The first three were scammers. The reason it took two weeks to sell it was, I think, because of the number of box store cruisers for half the price I wanted. People tend to not think about quality when they make comparisons. To most, a bike is a bike is a bike.
I gave the buyer the manual for it, and hadn't realized that Electra is a Trek product. Altogether, I spent $684 (£555) on it. But I had put over 4,000 miles on it in just over three years. I hope I'm done buying bikes, now. I have the fatty and the new step through to keep me happy. At the age of 77 I very much doubt a new bike will be coming my way unless Santa brings it.
