I was going to wait until I had reached the magic one thousand mile mark, before writing anything else about my Woosh Santana, but your enquiry has prompted me to act a little sooner. I have done almost seven hundred and fifty miles since the beginning of May, this year, with a two week gap for illness. I was sceptical of electric bikes but, after speaking to a lady customer one day, who does a twenty mile round trip each day to the hospital where she works, I realised they were a practical form of transport. She has done this trip for two years now, and says the battery is just starting to get a bit tired. She has a Freego which, I now realise, is almost identical to the Santana, but twice the price. My daily ride to work is only three miles each way, but on my days off, I seem to do about twenty miles each day, merely because it is so easy to ride and such a pleasure to ride. (I am over fifty nine years old).
I had to tension a few spokes in the back wheel during the first few weeks, but that all seems okay now. One pedal played up, and the grips are a bit smooth and plasticy, but I can find no other faults. The brakes work, the lights work, the gears work, it's easy to mount and dismount. It takes me where I wish to go and, when I return, it does not feel as if I have made any effort. All this with just a motor and a battery added to a bike. I have not tackled any real hills during my ownership. There must be others on this forum with hub-driven bikes of a similar price, who can give you more information. I have fitted panniers and a front basket, so can carry most things when I need to. The rear tyre still has its original fine pattern on it at this mileage, so it must be pretty hard rubber, as all the weight is usually concentrated at the rear, with tools, motor etc.
As far as gears are concerned, I feel that three hub gears, like the
ODK cargo bike, or the automatic set-up like the Momentum bikes, is the ideal for an electric bike. I tend to use a low gear or a high gear. Riding an electric bike is totally different to a normal bike, with the motor doing so much to help. I think the controller must play a large part, but it's rather out of sight and forgotten. I have never been a fan of hub gears, but they may have found their place with electric bikes.
It is worth going on the Ali Baba site with a search for ebikes, just to see what is available, from the poseur to the practical. This may help you get things in perspective, when you see what seems to be the same machine for sale in the UK, but at three different prices. Woosh seem to have made the effort with their website, to give as much help and advice as they can, when they are selling via the internet, and they were helpful when I contacted them directly. From your description of your transport needs, I think the Santana would be perfectly adequate.
