Just as reference; JV Bike and Reckless Bike Stores (which has 3 in Vancouver) both come up pretty well rated in Yelp. It's a starting point with a couple of companies that are familiar with EBikes. There were more; however, you should do a little research and see who is closer to you and seems comfortable to work with. Give each of the stores a call--only way to know other than just dropping in for a visit. Smart move, though to have a local company to help you!
