As the title says, I am looking for a way to save some money up at college this year and think this will be a definite help. Last month I spent over $390 on gas alone for work, the girlfriend and other travels. Granted I don't drive that much at college but the 1-5 mile commutes I do each week are wearing my car down. I have been looking all over the place and see a few companies that offer similar kits; SD Stinker, Bike Berry, Kings, and others. So is there really a better choice from any of the above suppliers? I must mention I am not looking to spend too much, meaning the $179 models have been where my eye is, and 66/80cc. Also is there anyway or any supplier who is running any specials that might keep the price down below $200 with shipping? I currently am looking to get a bicycle for this since the one I have I'd rather not modify, I saw Target and Walmart both have bikes that would do just fine (the one I saw a video of on Youtube, certainly shows it working nicely) http://www.target.com/p/magna-men-s-glacier-point-26-mountain-bike-blue/-/A-10993559 http://www.walmart.com/ip/Roadmaster-Granite-Peak-26-Men-s-Mountain-Bike/15711164 Regarding the engine, I have been looking into Bike Berry and can't find whats the difference between their "Mega Motor" and "Flying horse" models, I can't find a single difference. Can someone give me some pointers on this, looking to order Monday!
