Good Bike for the Price

A friend of mine received this bike as a birthday gift and asked me to assemble and adjust it. Just a word of warning to those who haven't ordered bike online, this bike will arrive partially assembled, so you will need some knowledge of bike maintenance to set it up. You'll need a set of allen keys, small adjustable wrench, cable cutter, and a pedal wrench to fully assemble the bike. Or if you can stand the dirty looks from your local bike shop... have them set it up.

The components are of good quality for an entry level bike. The mostly Sora drivetrain (front and rear derailleur and shifters) shifts well and is easy to adjust. If you are familiar with older Sora shifters that had a thumb trigger that was inaccessible from the drops, you'll be happy to know this model (ST-3400) has a paddle behind the brake lever just like the rest of Shimano's line. The wheels were true and the spokes appear to evenly tensioned. To get the bike to this price point, they installed some non-Shimano components (brake calipers, crank, and bottom bracket), but they work just fine. The brake pads could be better, but it's easily upgradable.

However, there were some annoyances during assembly. The front derailleur was just a little bit too high, so I had to lower it 1-2 mm to get good shifts. And the chain is noisier than average, even after lubricating it, at first I thought it was rubbing the side of the derailleur cage at times (it wasn't), but once you are riding it, you won't notice it when the wind is rushing through your hair :)

My friend reports that the ride is smooth and the STI shifting is nice (his previous bike had friction shifters). Handling is responsive... so much that he was surprised at how easily the bike turned. The tires he received were 700x23c, he would preferred 25 or 28 mm width since he plans to commute with it as well. He appreciates that there are mounting holes for a rear rack. Carbon fork probably means a front rack is out.

This is a decent bike, but is not heavy duty and needs some retuning after a good day on the trails.  The chain slipped a couple of times after steep climbs and the rims need to be trued.  I weigh about 165 lbs, so YMMV.

Bike is good for the price.  Some plastic parts where metal should have been used! Great bike to start out on but if you are mountain biking I would invest in a better bike.

I would have to say it could be a challenge to put together but once it was assembled it was no problem.  The seat is comfortable and the bike is quiet and smooth riding.  I like the display but don't believe the heart rate monitor to be so accurate but use it only once in a while to "approximate" my heart rate.  The one complaint is the handle bars are not secure and I usually have to adjust them away from me so that I don't hit my knees on them.  The fan has mediocre air output at "high" setting.  The price I agree though is pretty good and that it is worth the time to put it together and once assembled a very convenient way to get in 30-45 minutes on a bike while watching t.v. or reading.  Although the small area to set books are magazines isn't secure and books or magazines slip off while riding the bike.  Overall a good value for the price.

Nice bike. It comes partially assembled. Our handlebars were assembled backwards so I had to take them apart before I could put them on the bike. No big deal. Haven't ridden too much, but the little I've used the bike it seems comfy.

It's a sturdy bike. The finish is pearly white, not matte white. The brakes and derailleurs work well. My front gear shifter (on the left handlebar) broke within months of purchase but it was inexpensive to replace at a shop. Seems to handle rough/broken up streets well.

Bike arrived undamaged and well packaged.  The instructions are a little confusing as there are multiple models contained in them but got the bike together in an hour or so.  Have not ridden it a lot as yet as it so hot here right now but it handled well and gears shifted fine without adjustment.  Replaced the seat with one more padded but that is just my preference. The pedals do look a little flimsy so time will tell if they hold up.

All in all, for the money, this is a great bike. I have had it for a month now and I am very pleased with it.

Like other reviewers, the assembly was not the best experience because the instructions are horrible. However, I knew this from the other reviews, so my expectiations were properly set, and I was sure to read all the reviews for assembly tips. I put the bike together in about an hour.

The bike is very quite, and works well.

The resistance works well for a bike in this price range (its not super challenging, but certainly adds to your workout).

My only complaint is that at 5'10" I can just barely use the bike comfortably, however I am willing to deal with it for the price. Anyone taller than 5'10" may want to consider another bike.

The back cushion is not very comfortable, but like another reviewer said, it is nothting that a small pillow can't handle.

All in all, I am very glad I got the bike and would buy it again at this price.

It's a good bike and it was reasonable priced.  The one improvement I would like is for it to have higher handles.

I have no real problems with this bicycle, at most I can say the breaks are a little weak and the seat is stiff, but that's not an expensive change out. It was easy to assemble only really needing a crescent wrench and an a single allen wrench, then take it for a ride to get your adjustment's right. Unlike other reviews i haven't had the tires pop on me yet, I typically ride about 20 miles a week to and from, collectively. It will kill you on hills, too much of an incline and you're wondering if you should just be pushing it up along side you. the frame did occur some sort of rash on shipping, but it hasn't bent or twisted it and all it does is offset the white paint for the bike. All in all it's a great bicycle, i'm probably going to gift one to my brother for Christmas this year!

For a sub-$600 bike, it has a decent set of components. Suntour XCT fork is a little pogo-ey, but it's not the worst.

WTB Wolverine 2.2 tires are nice and grippy, actually surprised to see tires that nice on a cheaper bike.

Tektro disc brakes get the job done (barely), but I seem to constantly have to adjust them.

SRAM X4 drivetrain gets the job done. Not the greatest, but far from the worst. Can be a little difficult to adjust, but not impossible.

I did order some Wellgo MG-1 pedals to replace the stock Wellgo's that came with it, but that's a preference thing. I have big feet.

I will likely replace the fork and brakes. The rest of the components are within tolerances :)

Overall, unless you're riding some REALLY gnarly trails, or racing, this bike should be a good workhorse for most beginner to intermediate riders.

This is a nice bike for people looking for an inexpensive exercise bike.  I put it together myself and it was not that difficult.  I think it is solidly made, but if you want a strong more durable bike I would recommend spending a little more.  It works great for my wife and I with the joint usage of 3 times a week and along with our matching ProForm Treadmill this is nice.  One comment, the speakers are outstanding and you have to purchase the AC Adapter for ProForm for this bike to get the full use of it.

I got this bike looking for a road bike for getting to college. Over all its a good bike with a few upgrades it a great bike for the price.

Tips
--------------------

The rim tape in the wheels is bad before riding replace it. or you can even use 3layers of electrical tape.

--------------------

the pedals are cheap but i did not buy this bike for the pedals but the frame and wheels

--------------------

make sure all the bolts are tight, including the brakes, movement in the brakes is due to them being loose, the brake are the old tektro brakes under the promax name, the levers are also tektro Ergo under the promax name.
--------------------

three thing i replaced right away was the rear hub to a cassette hub $25, better deraileur sora $20 and a new bottom braket $10 with this the bike will drop about 3lbs to about 28 total and will be much stronger.

------------------
the frame and wheel are very good, the frame comes in right at 4lbs 22.5in frame (7005 alloy)

-----------------
if you also replace the fork, front hub, and handel bars and shifters and crank for another $200 you will have a sub 20lb bike with better parts then a trek 1.1

i highly recommend this bike

This is a solid bike, especially considering the price. We've had it for about a month now and it gets used most days.

Nice bike for the price. Fit my girlfriend perfectly (5'2"), so it's a good size for smaller people. The basket is quite cheap looking and flimsy, so I would replace that. Also, the sticker designs are not very nice looking either, but those can just be peeled off to leave the raw metal look (much nicer in my opinion).

Overall, 4 stars.

It's not a great bike, but it's definitely a great buy.  The seat is large and comfortable for my 6' 260-lb body.  The functions on the display are pretty extensive - speed, calories, distance, and a timer that can be set to count up or be set to countdown.  The adjustments to move the seat are a little more difficult than some are used to, but it shouldn't take you 30-minutes.  The cycle itself is pretty fluid after the first day, the tension system used to adjust the resistance works decently, you shouldn't need the higher setting ever on this bike.

Bottom line is this is a good starter bike - I got it to try and see what my commitment was to using a cycle.  If I stay on it for a year I will probably purchase a better model similar to a bike at a gym.  But before I spend $600-700 I figured I could test this one for ~$160 first!  So far, I am pleased with it.

I looked at this same exact bike at a box store. It sold for $200 more assembled.  Bike came promptly through UPS and was easy to assemble. Had to watch a video on the front brake assembly but that was the only gotcha.  The front wheel is not rolling true and the bike chain rubs on the very highest and lowest gears. Will have to get those two features tuned. Shifts fairly smoothly and is very comfortable. This bike simply cruises on the flats and does pretty good on the climbs as well. I am 6'0 and ordered the large. It is a great fit. I am a newbie to cycling but asked my friend who is an enthusiast. He reported that this is a good entry level bike. For the price you can't go wrong.

I put in 8 miles on it the first day I had it and loved it.  Eventually I will update the pedals to something high end but this looks to be a good commuter bike.
