Unbalanced and uncontrollable bike rides

Because young children need pedals to help them feel secure on the bike. Shoes are scuffed on the bottom making for uneven balance which causes falls.

It plays but does not stay in your ears while cycling.

The only thing nice about these bikes are the price.  The back wheel does not spin freely.  I brought it to a bike shop and paid to have it serviced and the rear wheel still does not spin freely.  Don't wast your time.  I bought two of these and both have the same problem with both.

I received this balance bike and as I was putting it together, I realized that they had sent me a faulty bike.  The handle bar would not screw into the frame.  At that point, I had already put the back wheels on tightly and could not take the bike apart to ship it back.  After 30 frustrating minutes, I finally dumped the whole bike back into a big box and shipped it back.  So frustrating as my son was very upset that I was sending it back.

I received this bike about a week ago. Considering the price, I didn't have much expectation, but I can't give more than two stars to this bike. The Q&A and the manual say that this bike can hold up to 240 lbs. However, the tires that came with this unit are labeled, "Max Load 75 kg (165 LBS)". I am slightly heavier than 165 lbs but, when I ride, the rear tire is pressed so flat to the extent that the wheel almost touches the ground, even though the tire is inflated until it is about to explode. In addition, the front wheel is seriously misaligned so the wheel and the handle not perpendicular to each other. When I hold the handle straight, the wheel faces leftward. There may be a way to fix this, but I didn't try. There is no instruction in the manual and I don't want to scratch it yet. I attach a figure for this.

* Update after two months
I changed my rating from two starts to four, since the major issues I had were resolved. I fixed the handle alignment issue, following the guide posted on the seller's website. I had searched their website initially, but couldn't find the guide until they posted the link in the comments below. I appreciate their quick response. As for the max load issue, inflating the tires harder seems working but not that reassuring. Although the seller claims that weight is distributed on both tires evenly, that is not true. Because of the saddle's position, the center of the mass is skewed to the back, so most of the weight hangs on the rear tire. I gave the bike to my kid, so I am not riding it frequently, but it still makes me anxious whenever I ride over bumps.

Overall, the bike seems to be solid. It is much heavier than I expected it to be and the brake pads were all turned in the wrong direction when it arrived in the package. Also, the tension on the chain was too high and the bike would keep braking without any brakes being applied. This should not have been the case. Since I do not know much about bikes, I did not realize any of this. Therefore, I had to take it to a bike shop for them to look at it and make a bunch of adjustments prior to my son being able to ride it safely. It cost about $25 to have these adjustments made, which should be built in to the overall cost of buying this bike.

I was really hopeful about this bike. My daughter wanted something pink with training wheels. I tried to convince her that a balance bike might be a better idea, but I relented. The bike arrived today and we set about assembling it as soon as it arrived.

Everything was fine until I started inflating the tires. I should say that I'm no stranger to bikes (or tires), I am a daily bike commuter and have changed out tubes in the past with no incident (but hey, there's always room for failure). The rear tube I inflated to 60 PSI (the rated range was 40-65 PSI). Then I inflated the front tube to the same. As I went to remove the pump it burst, in my face. With my ears ringing I turned to my daughter looking stunned and upset. She was so incredibly heartachingly excited about riding her new bike, and then poof (or boom) excitement replaced by immediate heartbreak.

I called around town and couldn't find anyone with tubes to fit these oversized tires (16 x 2.35, what in the @#$^?) but got close with 16 x 2.125. I picked up two since in my experience it's a good idea to carry spares. No big deal, the replacement tubes cost $14.

We got home, I put the new tube in, was careful to ensure that it wasn't pinched between the tire well and the wheel, and inflated it to (what felt like) a cautious 50 PSI. We took it outside and rode happily up and down the block for about 20 minutes. We even took it in the backyard and she rode in circles and back and forth a few times to get the hang of things. It felt like happy success.

About an hour later, after we picked her brother up from preschool (who also got a bike, but a simple balance bike with plastic wheels) we attempted to ride up and down the block again, but as we set out the front tube burst, this time with her on the bike. I mean, she weighs 44 pounds, are you KIDDING me?! I picked her up, screamingly upset now, and the bike, and we went into the back yard to fix things up again.

I replaced the new tube with the spare I had purchased (if you're still with me, we're on tube #3 now), even more carefully put the tire back on, and this time filled it to 40 PSI, which was the bottom limit listed on the tire. At this point she was tired of riding so we all went inside, had dinner, and I put the kids to bed.

This evening, with the kids peacefully asleep in bed, while the bike sat quietly in the living room, both the new front tube and the rear tube (which was stock) have now burst, inexplicably. I was only present for one tube's explosion, so I don't know when the other did, but, it doesn't matter. My daughter will be so heartbroken tomorrow when I have to explain why her bike is being returned.

I'm an optimistic sort, and so was hopeful that this would be a good first bike after the sticker shock I got from the local bike shops ($240 for a Cannondale?!). But now I'm thinking it might be worth it if, at least, the tubes don't explode from a passing glance.

Caveat emptor.

This bike was purchased for my son to use at college; getting around an urban campus. The campus has bike lanes, so no real mountain terrain to challenge the bike's workmanship. However, unlike the 'easy to assemble' claim, he had to take the bike to a bike shop to have it assembled. After riding the bike for less than a week, the bike pedal broke off. No, my son does not weight 300lbs. After the company sent a replacement pedal, which had to be taken to to the bike shop again for assembly.....He now has no brakes. After riding the bike for a couple of weeks, pressing the brakes to the max level in order to stop, he's decided the bike is not worth any  more trips to the bike shop or his safety. Unfortunately we have missed the return date, and it is not easy to box up a bike and return it. So, needless to say - this is a learning experience. Some things just should not be purchased on-line.

In general the bike is just fine, except for one not so little detail: there's a design flaw that creates a big security risk: the wheel (26") does not allow for a good turn if you keep the pedals in any other position than one at the bottom and one on top. If you place them in other position, the foot closest to the wheel will touch it, "braking" it and making you unstable. I have almost fell about three times for that same problem. It won't happen if you're already moving, but for instance if you're just starting and want to turn in a more tight angle, you will have this problem. Very annoying.

I was able to get this to fit fine on my mountain bike, but the trouble is it is adjustable.  It kept falling down and hitting my bike tire while riding over small bumps (gravel road).  By the third ride, it hit the tire and broke in half.  If you are planning to do anything other than ride on perfectly flat paved roads, get something else.

Be aware this could be useful for a city riding where you don't care about how comfortable or long it takes to finish a ride, but this makes your ride feel sluggish and very heavy.

The bike we received had several mechanical problems.  The Critical Cycles customer support was not prompt in addressing the issues.  I cannot recommend this bicycle.

Let me preface this review by saying that I am a reasonable person, not some kind of moron who doesn't know how to use a tricycle or who has a daredevil kid doing unusual things.  My two and a half year old daughter is very coordinated with good balance, and this tricycle tips over literally every time she rides it.  If there is any forward motion at all and the handlebar is turned more than just slightly in either direction, it will tip over.  Even while I hold onto the back of it to steady it, it still tips over.  I don't know what the standards are for mandating recalls, but this thing should no longer be sold.  At the very least, make sure your child is equipped with a helmet and be ready for some tears.

You will see many reviews for noseless saddles where people complain about a lack of control.  This should be obvious as the whole point of the nose is for control, but that is not my complaint with Schwinn's attempt at a noseless seat.  I couldn't even stay in the seat long enough to determine if control would even be an issue.

I can not recommend this seat to anyone for any reason.

if you have a smart phone or tablet, just download the "tilt-n-drive" bike/motor cycle/dirt bike games for free.  Graphics are nice and it is pretty fun but i'm just a different kind of gamer.

The handlebar does NOT steer or turn smoothly. I suspect this is a defective unit that steering or turning seems to be very "sticky". My little one has lots of difficulty to maintain his balance as result from this "stickiness" of the steering. The point of this balance is to train little one's reflex to turn or steer to maintain balance, but the design is prohibiting or defeating the purpose.

I will NOT buy this.

This bike is very cute. The ride is very comfortable, and I feel that is in part to the tire size and the seat.

I like how far the handle bars are apart, if you are large chested you don't feel like one of the girls are going to get in the way of steering. That was an issue years ago on a mountain bike.

The position for ridding is great, I have had two back operations, and this causes no pain. I have not been on a bike since 1990. Yes I am older, over 50, and this is my first brand new bike. All my bikes I ever had were used from someone or found in a dump and fixed.

I knew I wanted more than one speed, but did not want a lot of them either, so I got the three speed. I don't like speed one, it just is for trying to get up the hill, or in my case the little knoll in the road. On level ground I use third speed, I can go best with that one, after I get out of my driveway, they paved our road last year and I have to push it over the hump.

The instructions were very bad, it gave all wrong sizes of tools to use, but was able to figure that out fast. I did get this out together wrong on the front tire. Like a kid and in a hurry, I did not pay attention to how the front spoke was facing. So I had to take it all off and start over, that was after going crazy for half an hour trying to figure out how I was going to ride this. I happen to set the peddles and seat pole on my tv stand in the garage and could not find them.

When I was trying to figure out how I could ride this with no seat and peddles, I was on the phone with my mother in law. That was where I goofed, I should have been trying to concentrate on this and could have saved me grief.

I have purchased a basket for the front and a horn along with reflectors for the spokes. It looks very sharp or some could say crazy. The only reason for not giving this five stars is the seat is in the lowest position and I barely reach my tip toes to the ground. The bike stated it was good from 5-6 feet, and I am 5' 2" .

If you are thinking of this can be a good bike, you bet it is and once you get on you don't want to get off, at least me. I put in my basket a tablet, a Bluetooth speaker, water bottle, battery charger, and cell phone. There is what keeps me happy, the music, and I don't want to stop.
