Re: Long distance travel
180 miles a day on a bicycle? That's an ambitious goal, for sure.
Like was said, you'll need one heck of a comfy seat and don't abuse the engine. I've done several 60 and 70 mile rides in a day with no issues but I build my seats for comfort. I also use large motorcycle style fuel tanks that hold over a gallon, in one case 2 gallons.
The Chinese 2 stroke engine, if set up right and treated with care can easily carry you 180 miles without troubles but there are other aspects you'll need to consider such as wheel bearings and proper chain lubrication. Good tires are also important.
Let us know if you try your extended run.
Have fun and ride safe.
