Thanks for the positive comments chaps, the bike was built on a budget just to keep me amused in the evenings, the frame was salvaged from the tip and new tubes cut and brazed in to suit and i made the tank (fortunately it does not need to hold fuel or i would have been in trouble). The Motor is only 200/250W the legal maximum in the UK and is no flying machine. The range should be around 20miles i think, though it all depends how much you use the pedals. I truth i have hardly ridden it and will be looking to sell it to find something else to make. The only drawback with this arrangement is with the batteries in the tank it does make the bike quite top heavy.
