You probably want to stay away from SLA batteries. Check out ebike.ca, talk to one of their sales representatives and have them put a kit together for you. Get a LiFePO4 battery from pingbattery.com that will last you three to four times longer than an SLA battery. Remember you get what you pay for. Goldenmotor.ca also has their Magic Pie 3 hub motor which you should check out.
What kind of trail bike are you planning on putting the kit on? Make and model? Does your trail bike meet the minimum requirements for an ebike kit? What will be the main use of your ebike? Commuting, etc? Will your brakes work with the ebike kit? How far do you want to travel before you have to recharge the battery/batteries?
Check out Greg Davey's website and his 50+ mph ebike (http://www.fastelectricbike.com/book.html
). Read Greg's first free 20 pages of his book. You may not want/need to go 50+ mph but if your bike is built that strong then you know it can handle the lower speeds you do intend to go at.
Keep us posted on what you find.
