"stupid customers", "ridiculousness". A welcoming bunch you guys are...
Am I to worship the all-knowing bike gods? Sounds like a bunch of children.
Thanks for the laughs, boys.

The Thruster is basically painted toliet pipes with the cheapest wheels they could get away with on it. It was not designed as a durable bike for clydes or even for regular folk, it really wasn't designed more than plopped out and kludged together by someone who could care less about anything but making a small pittance per bike.
Your argument against 700c wheels is absolutely crazy and seemingly based in Wally-Mart bikes not in actual properly built wheels. My touring bike fully loaded is way heavier than you and it rolls on 700c rims and tires and my last tour was almost 100% off road and I had zero issues with the wheels or sizing.

Funny how people who act like children are the quickest to say other people are acting like children.

Update!
It's been a few years since logging on here, so I figure it is time for an update.
I just broke 2,000 miles on my Thruster.
Here is a list of original parts still going strong:
frame
wheelset (had to replace bearings in one wheel & repack both with grease once - I haven't always been good about maintenance after riding in rain. I also trued the wheels myself once, which seems to be holding up surprisingly well)
Brakes (honestly I thought the brakes would have been the first to go, but they still work, & well at that).
Here is a list of parts I have changed by choice/preference (btw, these are mostly things people upgrade to their preference at any level of bike purchase)
Tires & tubes
Pedals
Seat & post
Added bar ends
brake pads
Here is a list of things that I changed to avoid additional maintainance:
Bottom bracket & crankset (I probably could have cleaned & repacked the BB with grease but I didn't like hitting the cranks with a hammer to get them off every time. Instead, I went with a shimano sealed bb and a crankset that can be removed with a crank puller for about $30 bucks total. The crankset, & needing a hammer to remove it, was by far my biggest complaint about the Thruster).
Added an aluminum spacer to improve the chain line.
Here is a list of things that actually began to fail while riding:
The bearings in one wheel started to grind the last 20 miles or so of a ~60 mile ride. (This may have been my fault for not repacking the bearings with grease after one ride in very heavy rain. I made it home without damage to the wheelset, & only had to put up with the sound of grinding metal).
I'm posting this for the sake of anyone that might benefit from this information.
Sorry to those who had hoped for this thread to be dead already... dead as a doornail.

Fixie Thruster
I said basically that I think that my left crank arm keeps going out because I weigh a lot I don't think that the bike is "cheap", its because when I get up to push on a hill, on that aluminum crank arm, it gets more worn up since it is a road (flat street) bike. I then said who am I kidding? I'm a F A T A S S lol

do you know that when a crank arm “goes out” it most likely damages the spindle? And that putting a new crank arm on a damaged spindle is most likely going to accelerate wear on the new crank arm, causing it to “go out,” and that whole process damamges the spindle even more?
Do you actually see damage on the spindle? I mean the damage I see is mostly from the arm where the square turns bigger and gets looser (which causes the arm to eventually wobble off). How would I know if my spindle is damaged?

The spindle is hardened steel, while the crank arm is soft aluminum. Thus, it is highly unlikely that the arm can damage the spindle. If the spindle were damaged, you would see gouges or other damage on the flats of the square taper where the arm mounts.

I thought I read something like that. Why do they do that? Why do they make the arm aluminum and the rest steel?

The spindle needs to be hard because it rides against the bearings, and it also has to withstand the stress of bolts threaded into it very tightly. The arms can be aluminum for lighter weight.

Either the aluminum on the Thruster crankarm is soft, leading to it deforming under a load that a higher quality part would withstand, or it's not being torqued correctly, which leads to motion at the taper interface and working the aluminum side loose. When you install the crank arm, do you use a torque wrench, or just good'n'tight?

Quality aluminum crank arms hold up to pro cyclists pounding on them. Especially track racers have quads that look like they came off a bodybuilder. I doubt you are making more force on the pedals than they do.

I do the goodntight but now that I know I should be using a torque wrench. I've gone though about 2 crankarms from Amazon, it has to be like you mention regarding the quality of the arm (but probably both in my case) Thanks for the information and advice.

The thruster is definitely not using quality aluminum on those cranks, more like recycled beer cans. Sitting around scratching your head of what's wrong with the thruster is a waste of time and money tbh, if you ride regularly it's worth investing in a better bike then dealing with the same problem over and over.

My first time suggestions are too spend money on a quality bike and if your budget is below 600 you might consider raising it. You will be much happier with a bike that costs a little more because generally it will have better components and sometimes better frame materials or at least a better fork (like carbon fiber or higher quality cromoly steel). The less you spend the more pay later on fixing the bike and dealing with shifting issues and braking issues and having to replace parts and generally the less happy you are with the bike. Test ride a bunch of bikes including some out of your budget and really take them out for a little bit don't just ride for a minute and say "bike is fine" because you won't really get much in that short period but also know that a short time on a new saddle or looking at a saddle will tell you absolutely nothing about it other than it is a saddle. Don't just buy a Trek because that is the brand you know, same with anything else, make sure you test ride it and talk with the salespeople and get a good sense of the bike.

Walmart... thruster... ‘fixie’ ... how did this get to 5 pages that I’m not going to read through? My head hurts just thinking on it. All I can say is the thruster is a joke. No one should ever buy one for any reason. I’d maybe burry one in a time capsule with a note, apologizing that it was ever birthed

I would stay away from overpriced name brands like Trek. You can get much better quality from less famous brands for the same price as Trek. The Trek FX1 has a hi-ten steel fork, which is an automatic disqualifier IMO. I would want at least a butted chromo steel fork paired with an aluminum frame, and preferably a carbon fork for better shock absorbtion. I would also look for a bike with sealed bearings in the wheel hubs, bottom bracket and headset. Another thing to look for is decent brakes and shifters, which you can only assess by riding the bike. Also, expect to spend additional money on better tires and saddle, since the stock parts are usually low end. Finally, buy your bike at a local bike shop, not online, even though it will probably cost more.
