4 Stroke Bicycle Engines & Kits4 stroke motorized bicycle engine kits are great if you want reliability or do not want to mix your oil and gas. Learn from each other how to get the most out of your 4 stroke bicycle engine
The main problem I have with rack mounts is how high they're mounted on the bike and the tank looks like it's almost a foot above the seat. Could an upsucker carb possibly be offered in the future that could be used with a separate gas tank mounted elsewhere (lower), possibly between the engine and the seat? I think the clone engines actually can be bought with the option of a downsucker or upsucker carb. Also, this would allow the user to use a much bigger tank. I have a black plastic tank off a tiller that would be ideal and holds half a gallon of gas and would fit in the space between the engine and the seat.
