I am building a motorized bike that will allow me to do long trips on the bike.
I will be starting with a yet-to-be-chosen mountain bike. The bike will have an aluminium frame, shimano deore ls or xt components, and disk brakes, likely Avid.
The bike will also have a freeradical, from www.xtracycle.com, installed, to allow for some serious cargo. The engine will be installed as low as I can get it, behind and below the seat.
I will build the drivetrain for the engine myself.
I intend on carrying myself, the bike, a trailer, my 60lb dog, plus 200lbs of cargo. I figure the total weight will be 500lbs.
My goal is to travel with this load at 30mph (no faster), with a little power on reserve to maintain speed up a hill.
My questions are:
1) What horsepower would I need?
2) Will a standard bike chain work as the drive chain for this engine?
3) Is there a freewheel sproket I can use that will handle the engine needed, and be compact enough to fit on a bike?
I know 500lbs is a lot for a bike. about 100 of it will be the dog, who will be in the trailer, towed behind me.
I know this is a srange project, but it is what we want to do. With that much weight, I don't know how much I'll be able to peddle, but as long the the engine runs, it won't matter.
Oh, the trips we want to take will be as long as 350 miles one way
Thanks
