I think the fx+ is an excellent bike. There is one sticking point however, The electic system is a Bionx. While well made, they have choosen to design their system in a way that doesn't allow aftermarket componets to be used. If you have problems fixing it yourself is very limited.They will not sell you parts.
If your friend still has his bike what is it? Is it a Tidal Force? We may be able to help you get it going again. You wouldn't believe the advancements in batteries in just the last two years.
I would do a Google search for Electric Bikes or Electric Bicycles; lots of information out there. We have looked at Pedago and Prodeco (assembled in the US but possibly made with foreign parts) but have chosen to stay with our Schwinn World GSE but I would not recommend them due to poor Schwinn support. You could also read past posts on this topic in this Forum.
Best thing you can do is build your own e-bike, that way, you can always find spare parts and keep using it. Besides, if you build your own, it's going to be more powerful than one that you buy that's ready-made.
Thank,s for your help i think i just hold for a wile and have another look around my neighbour was out to day and bought a Klakhoff Agattu e for his wife so i will have a look at that when he gets it on Wednesday.
