Hello everyone I am a new enthusiast I have done research on my build for about the last month and FYI this is the first chat room or forum that I have ever been a part of LOL. So I apologize in advance if this gets lengthy. Ok I will just jump right into it I researched ebike front wheel or rear wheel I researched 2-stroke 4-stroke engines and what I have come up with is I will be the most comfortable for my daily commute with a 4-stroke reliable engine. E-bikes are cool but they have limitations on distance and the prices are ridiculous. I have not bought a bike the current mountain bike that I had planned on using does not have a big enough V space ( which sucks because it already has disc brakes ) my dream would be to have a mountain bike with a central mounted 4-stroke engine and 3 to 4 inch Fat Tires. My initial Vision was a three-wheel Fat Tire trike, the purpose of my build is for a commuter I work about 13 miles from my house so its 26 miles round trip. As well as tooling around town just for fun and quick grocery store runs. I live in Minnesota and soon old Jack Frost will be here hence the fat tires and three wheel trike build. I have been on multiple sites viewing the price of a 4 stroke bicycle kits & it looks like I will be out of here about $260 to $300 for a basic kit or the Honda one which is like $500 (probably won't happen) all my searching has led me here. Especially since it seems like I'm the only one that I have around who thinks this is a good idea LOL. Okay to my question what is the best and most cost-efficient place to get the engine kit and do you really think I should scrap the Fat Tire trike idea?
