Total NOOB in Minnesota

Hello everyone,
I'm completely new to this game, but I have been getting so much helpful info searching on this forum I decided to join up. I've never motorized a bike before, but I just ordered my first kit after a couple weeks of searching around for info. I decided to start electric as it was quite a bit cheaper and as I'm not very mechanically inclined, the install looked like it was much easier. I do hope to eventually upgrade to gas power. Got a cheapy 700 watt 48 volt kit online, and I plan on adding it to a Schwinn Meridian Trike that I got this spring. I'm open to any help the veterans here have to give!

Kit cost me $199, but I have to supply my own batteries, so it'll end up being a total of around $320 when all is said and done.

I need that much power to haul myself around, I'm a pretty big guy, just over 300lbs.

A company called XcellSior. They have a website that you can order from, but they also have deals on ebay sometimes. I got it cheap on a last minute ebay bid, but even if you order it off their site it's still only $259.

I'll post the website once I'm cleared to do so. I just started so I can't post links without getting in trouble yet!
EDIT: Here's the link
