I like the ansmann that you mentioned and if I could get that one I probably would because of the already mentioned spec and warranty, the fast4ward is too similar to the woosh sport CD, component and weight wise to justify the extra expense, although its got a better battery and charging time.Why do you prefer woosh than ansmann? Or fast4ward? Any particular reason? Please share....
I particularly like the Sport because it ticks so many boxes for me, price, weight, looks, frame size, full throttle,5 levels of assistance, reasonable components, Samsung battery, cost of replacement batteries etc. and reputation of customer service. They are also getting in new kit to build more, so hopefully a few upgrades too, just have to wait and see before making a definite decision.
