I'm a firm believer in the saying "If you want to go faster, buy a motorcycle".

Is this because the frame isn't designed for a heavier motor and the torque forces that are put on a high speed strong pulling motorized bike?


One reason why I want a motorized bicycle is because they aren't as fast as a motorcycle, although I have looked at old 200cc motorcycles like the CB200. Someone has a CB750 for $600 in my town that needs a lot of work and my first thought was actually--- How can I make it slower!

Not just the frame, but think about the forces on the tires. Wheels that spin at 40+ mph get balanced so the wheel doesn't wobble. Enough wobble, and the tire can unseat itself. The tube can pop if that happens. Even if that doesn't happen, the centrifugal forces alone can blow the tire. Bike tires aren't meant to spin that fast.

Most bicycle brakes are v-brakes, which stop well at vike speeds. Much past that and your stopping distance goes down tremendously.

But yeah, the frame can give out, which is equally disastrous. Play it safe, and get yourself a small motorcycle if you want to go car speeds. Learn on something small at first. I learned on a Yamaha XT250 enduro. I worked up to a Yamaha Bolt (950cc twin).

I ride in the lane like a motorcycle. My bike will top out around 45 give or take, if it's colder it will top out 50. The edge of the road always has all sorts of debris and it's easy to get a flat... From my bicycling days I used to get a lot of flats all the dam time.

Mikey, don't buy the cb750 that needs work. A similar bike in excellent condition is fine. The reason is that there are 4 cylinders, and 4 carbs. The inner two carbs are very hard to reach and therefore hard to tune. Better to find an inline twin. To make it slower you can put inserts in the carbs that limits the airflow and adjust your mixtures to match (less fuel/air = less power).

Agreen, where do you get this info about over 40 etc? People who ride downhill mountain bikes often exceed 40 and subject their frames to far worse shocks than we do with our motors. My bike frame HAS cracked in the chain stay due to my own error, I had modified the frame in that spot and it weakened it. However most frame cracks that happen are in the chain- or seatstays, and they don't cause an immediate accident. I just noticed it on my bike when the rear end felt a bit soggy.

The attraction of building high powered motorized bikes is in the handling and versatility. It is awesome to ride and throw around at under 120lbs, it can be pedaled, and you don't have to ride in the bike lane with high risk of flats and getting hit by a car going 20mph faster than you. I take my space in the lane and no cars get close to me like they did when I was a bicyclist sweating in the bike lane. Also, maintenance is very cheap, new tires cost $15 and the riding experience is easier than a motorcycle (automatic). Probably this year, my bike if not sold will go through a major do-over, more power (20hp), full suspension, and possibly the same weight or less. The DMV calls this a "motor driven cycle" which is legal for a small lightweight motorcycle, or a very high powered motorized bike with no pedals.

I can say one thing, ever since I put a license plate on my bike drivers seem to give me more room and more of the road than they used to.

Those aren't your typical bikes. And there are most definitely videos of downhill bikes breaking and having magnificent crashes.

Ever experienced a tire balance problem on a car below 40? On a bike? The weight of a bike rim is very low, so vibration on it can be pretty negligible. But cruiser tires and anything much larger than a hybrid 700c wheel can start shaking at speeds faster than pedal power. And yes, the tire does begin to deform and balloon as centrifugal force acts on it. That's one reason why cars have steel belts in their tires.

I ride in the center of the lane unless the speed limit is above 40mph, because at or below 40 I'm not inconveniencing anyone as I can keep up with the traffic. I also ride in the center on roads with faster speed limits anywhere where it is unsafe to pass, so that people are less tempted to do it anyways. Any road with a 45mph speed limit or above and I'm in the bike lane or off to the side.

I think you're 'ballooning' this a bit out of proportion. Car tires run belts because they are very wide with no sidewall pulling the middle of the tire in. Our tires are (relatively) thin, light, short sidewalls, and the better MTB road tires run higher pressures. They are always out of balance but only by a few grams. We are definitely good to 40mph and above that, generally the tire soaks up the imbalance for the most part.

The worst balance problem I have felt in a car was at 62mph from dirt stuck to wheels from rally drifting. This imbalance amounted to several ounces of misplaced weight!! not the grams we deal in.

It's perfectly legal to ride, it's my damn right to do so, and if I inconvenience someone by having to put their turn signal on and move their steering wheel 1", then they shouldn't be driving anyway.
Damn I really want to move there! Legal bar hopping w00t!

Anyways on topic, my bike tops out at 39 mph on flat land and 43 down hill so I ride in traffic always. Here in the city max mph is 35 and I can easily break the speed limit and keep up with the flow of traffic or pass them if I feel like it.

If theirs a bike lane its great you can scream past the cars on the right hand side.

Helmet is optional here, I wear one when I'm traveling far or going to work. Other then that I don't wear one cause I don't hammer down when I'm just going for a beer run or troubleshooting the engine.

Tbh, I prefer hitting the old dirt logging roads and raising **** out in the woods where I cant get in any trouble. Wait scratch that last time I was on a trail a game warden tried to bust me for not having registration but he had never seen one in the middle of the woods before so let me go because he didn't know the laws of the motorbikes on private ATV trails.
