Here is my basic opinion. Yeah, you can make a bicycle go 100 mph by drafting a car or going down a steep enough hill. But just because you slap an engine on that bike and you happen to be giving it gas while drafting a car or going down a steep hil, does that mean you get credit for having the fastest motorized bicycle? NO. Anything you do to assist in achieving a certain speed that does not involve the bike or the motor itself simply does not count. There have already been plenty of people who have used these tricks to achieve these speeds. And as far as the engine goes, an ht engine is probably never going to go 80mph under any kind of load and survive it. The gearing required to make an ht engine go 80 mph under gas power alone would require extreme rpms that the engine is simply not capable of.
The crank will let go way before you come any ware close to 80 mph . You will need way more horse power to go 80 then that crank will ever handle . After about 5 hp its not if its when its going to break .I have in my head ideas that would blow your mind. Who owns this one? Whats its hp rating?
Wondering if anyone knows where I could find a seat like that, or if it is a custom?Going down hill does not count!
This is the most powerful 66 cc China Girl 2 stroke on the planet!
Case inducted reed valve and modded to the limits of breaking.
I doubt if it would go 80 mph?
It would need some serious streamlining to go much faster than 65 - 70
That seat is pretty cool, its got to be custom.Wondering if anyone knows where I could find a seat like that, or if it is a custom?

would help if the people reporting a story got their facts rightFunny how 90cc went to 80cc to 80mph. At least I didn't follow but that's just me. As far as going 80mph, there's this for reference: http://www.elsberg-tuning.dk/recordbikes.html
Hope the link works. I think it's pretty interesting what can be when people put their minds to it.
That's all cool and everything, but we are not talking about pedal-only speeds. We are talking about motorized speeds. Yes, there are bicyclists who can go extremely fast. They are obviously very well trained and conditioned riders, and at least some of them are probably professional. There is a big difference between a trained rider and the average joe.time to educate you on a few things....
human flat land pedal only speed records are....
Current WHPSC Records:
In 2009, Sam Whittingham broke his own record again for a human powered speed of 82.819 MPH!
In 2010, Barbara Buatois broke her own record, with a women's human powered speed of 75.69 MPH.
In 2011, Greg Westlake broke his own record with an arm powered world speed record of 45.68 MPH.
this is done using less then 1/2 a horse power on a BICYCLE
wrong again its in the GEARING you can either gear for power or speed.... those bikes are geared for speed and could not climb a hill at all without being pushed up it. If you read the posts and the links you would know it took almost FIVE miles to reach that speedThat's all cool and everything, but we are not talking about pedal-only speeds.

Chill I dont plan running this in the city. I have a nice stretch of ol highwayjust east of El Paso. My Pa is law enforcement out there. If I accomplish this. I assure you it will be under the safest of conditions.When I want to go 80 MPH I do it on this.
IMHO doing over the top stuff on the Motorized Bike will only give law enforcement fire power to use against the hobby in areas of the country where they are barely tolerated as it is.
:EXAMPLE:
6 o'clock new flash......... Man killed on home built motorized bike while traveling at speeds believed to be at 70-80 MPH, to be clear about what a motorized bike is, it is a typical bicycle that has had a gas engine installed on it, the officials we spoke to told us they are dangerous and probably should not be allowed on the public streets.
I wonder how many normal 25-30 MPH MB would be allowed to run around town as they had been after an ordeal like this happened, I'll bet it would be screwed up for everyone who had one and they wouldn't be tolerated in that town anymore.
50-60 on a Bicycle is crazy fast, 80 on a bicycle is stupid fast....IMO
just my $0.02 nothing more, nothing less, that all.
Peace, Map
All and all have you seen the bicycles they make those speeds with? They need a push start just to get moving. Its all about the gear always has. People are only limited by their imagination.wrong again its in the GEARING you can either gear for power or speed.... those bikes are geared for speed and could not climb a hill at all without being pushed up it. If you read the posts and the links you would know it took almost FIVE miles to reach that speed
