Have had my Woosh sport CD a while now, but have decided to sell and buy a couple of folding bikes, so we can take them in car on holidays and days out. Wife's sold her bike and I'm going to probably stick mine on Gum Tree. Question I have us re gears, on the Woosh changing gears when under pressure needed a knack to avoid lots of noise and complaints from derailleur gears, the back worked OK most of the time. Is this a problem with all electric bikes with derailleur gears, as if it is I'm sure the wife wouldn't cope with it at all,her old bike had Nexus hub gears,and was no problem. Looking at bikes, it seems lots of fold ups have derailleur.
