Can a motorized bicycle make a 100 mile trip?

A 2-stroke or a 4-stroke will have no problems doing a 100 mile trip, so long as the appropriate type of Loctite is used on nuts, bolts and screws that are prone to vibration related problems.

It is most important that a 2-stroke is jetted correctly, for this will be in large part what determines long term reliability when operated for long periods of wide open throttle at sensible rpm.

A 2-stroke (when jetted correctly) will return approx 100 kilometers (60 miles) for 2 litres (0.53 US gallons) of fuel when using a SickBikeParts shift kit that allows the engine to operate at 3,800 rpm at max cruise speed.

A 4-stroke engine is likely to be a little more economical and is less sensitive to incorrect jetting, but for the same engine size, it will be less powerful, if both engines are optimised to produce optimal power.

These links show some of my long distance trips, where the engine was working it's heart out the whole way; brutal mile after mile after mile:

Another important point is that you will want a comfortable seat; ideally having some level of shock absorption to make long distance touring a pleasant experience on your backside.

This is my setup, which has proven to be extremely effective. Don't for one second be shy about purchasing a ladies comfort seat, because a ladies seat is thickly padded and designed for comfort:

I have this version but in the lycra covering http://www.marwi.com.tw/index.php/en/light.html?page=shop.product_details&flypage=yagendoo_VaMazing_1.tpl&product_id=336&category_id=38

And this suspension (long travel Cane Creek Thudbuster LT) seat post has proven to be very effective with (soft) grey elastomers.
I ordered the 25.4mm seatpost as well as the correct seat post shim to fit the seat post tube in my bike. Ordering the smallest seat post diameter allows you to fit your Thudbuster to any kind of bike by ordering another shim of appropriate size.
