Thanks for the info. The SLA is all I could afford but I plan to baby the battery. If I get 14 to 15 range that will be good for me. I cannot see going 10 miles away from the house and not being able to make it back. Most places I need to get to are less than 5 miles away. I choose to go with Ampedbikes for the price. Again, all I could afford a complete kit for 501 dollars. I did have to get torque arms for the front fork another 25 dollars for a total of 526.00 spent.
I have read with a 48 V you can get more speed but I don't know if i will need it. The forks are steel I suppose.. a magnet sticks to them and the dropouts. My only real concern is if the motor will even fit. I have a 26 inch mountain bike and at the dropouts I have 4 inches. About an inch above that the forks get an inch bigger giving me a clearance of 3 inches. Well I took the plunge and ordered, so I guess I will find out when it gets here.
