The bike cost me £350 (I believe it was 800 new) I did get a spare battery with it.May I ask how much did you pay for this bike? There is a lot of wisdom in what Andy wrote. Maybe it would be wise to cut losses and start fresh? After all cycling should be enjoyable.
I have paid £8 for indexing the gears and £25 for fitting a quick release skewer to be able to fit it in my car if required.
Also the previous owner had taken the pedal assist disc off (because they didn't like the way it jolted away when starting peddling ) and that was put back inclusive of cost at the same time as the quick release.
So at this moment in time it has cost me £383 and the electric to recharge the batteries.
I am only cycling for pleasure and I know the battery life is not very good as I think I have been using it the wrong way up to now, ie not peddling hard enough to stop the assist from using battery life, but this is why I have been asking basic questions and most of you kind folk have been extremely helpful with parting with knowledge and tales of your experiences.
My main reason for getting an ebike was to get up the hill to get home as I live at the top of a hill, so although the battery life on my bike is not what it should be, as long as I leave enough juice in one of the batteries to get home I will be satisfied with my purchase.
Thanks Les
