Thanks people, I wasn`t too upset, I purchased a 36V 16Amp battery from Yose, delivered from Germany in just a few days. Good quality product, well packaged with everything you need, only had to change the connectors to spade type and stick it in the bag on the rear carrier. Very good company, very fast reply to e mails. My most used bike is my first one I purchased (which is what the battery was for) A Powertrek Dynamo. To be honest it has been a superb bike for what I paid ( I think it was around 600 UK) I was told when I purchased it on another e bike site (no names ) that it was rubbish and only afterwards did the guy who launched Oxygen tell me it was the design he took over and had ridden for months with no problems. He actually moved abroad I think but sent me free of charge a brand new frame that he had in the warehouse before he cleared it out but doubt I will ever use it now.
