Koen Bike, 18 Inch Bike for Kids Ages 5-9, SmartStart Ergonomic Design for Kids, Adjustable Seat Grows with your Child, Rear Coaster Brake and Front Caliper Brake, Training Bicycle

We purchased this about a month ago and it’s been a great intro bike for our three year old. We purchased the 14” model and it’s a perfect fit, our boy is currently about 40” tall and he rides this on the lowest setting. He went straight from a three wheel trike with the pedals at the front to this and was pedaling on his own within minutes. We did lube everything up after assembly and feel it rides very smoothly. We did get this on sale and while I feel that the normal price is probably worth it, I’m glad I didn’t have to pay that! I do like that it doesn’t look like a little kid’s bike or have characters on it, I think that makes it more versatile and something less likely that he’d lose interest in. Overall, a solid choice for a first ride.

This Schwinn Koen is the perfect first bike for my 4 year old son! I chose the 16” wheels as he is just at the bottom of the height range so he has room to grow into the bike that it will last us a couple years. His peddling experience was between a big wheel and a classic trike, so this did take a few minutes of practice for him to get used to the resistance of peddling this bike and the factor that peddling backwards brakes the wheels. He is 39” tall - I kept the handle bars at the height they were set to and installed the seat at the lowest height. Assembly took less than an hour solo, the bike comes mostly assembled with a few pieces to be added on. My son LOVES riding his new “big kid bike” and I’m at a light jog to keep up with him! It won’t be long before we’re taking the training wheels off.

Reading some of these reviews had me a bit concerned. I believe that many are written by individuals expecting the bike to arrive ready to ride. This is not the case. You should avoid making this purchase if you are not mechanically inclined. With that said, assembly is not difficult. This will include adjusting the hand brakes. These are the items usually already done for you when purchasing from a bike shop. A lot of reviews mention issues with the crank bearings failing. I believe this is caused either by they way the bike is shipped or by kids dropping the bike on its side too frequently after removing the training wheels. That is because the crank housing is plastic. It’s the only thing that is lacking of typical Schwinn quality. When the bike arrived at my house, it was clearly marked not to place the package on its side. The delivery person did so anyway. Before I even pulled it out of the box, I checked to make sure it was not damaged and that there were no missing parts. Good to go! This is a very nice kid’s bike and my son loves it. The bike is fairly lite for having a steel frame. If your kids requires an 18 inch model or smaller, I would recommend it. If you are looking for a 20 inch model, I would consider another model or brand, especially if your kid is an aggressive rider. Good luck!

I'll start with this is a great bike. That said, the person who pre assembled this bike had no clue what they were doing. The front brake levers were literally vertical, the rear wheel end nuts so loose they would have fallen off, and the inner rear wheel nuts were so tight they pinched the rear wheel so tight it wouldnt even spin. Don't even get me started on the actual brake pad setup on both sides which most people aren't comfortable dialing in. I would have rathered they sent it disassembled honestly. It took 15 minutes to set up, and more than an hour, plus a visit to the bike shop to make it functional since they wrenched the inner rear wheel nuts so tight I couldn't even address the issue. The setup was so bad I felt like I needed to check everything just to be comfortable. So... Great bike quality and components for what it is worth, but DO NOT ride out of the box. There's some sketchy assembly line stuff going on there.

PERFECT Gift for Our 4 year old Grandson! Quality, Right Price!!! Win Winnnn!!!!

I bought the red version from Amazon Warehouse (Like New). The box had been opened before but the bike was not put together before. The number plate was missing a screw and the sticker on the front was scratched and ripped. Not a huge deal. The bike went together easily however some things needed adjusted. The steering tube had a notchy feeling so I backed off the top nut a half turn and that fixed the issue. The chain and rear wheel (pre-assembled) were also very tight but I was able to loosen that up a bit. The rest of the assembly was simple and I didn't need the manual (it's a bicycle, not a rocket engine). As for the ergonomics and the SmartStart system, I think it's fantastic. This bicycle looks like it was made for a child's body. It's not all scrunched up like most children's bikes and the proportions are perfect for my son. Really impressed. My son is 42" tall and has an inseam of ~17 inches. The 14" bike is perfect for him AND he has room to grow. He's able to put his tippy toes down which gives him confidence and he still has enough room to comfortable pedal. VERY happy with the purchase. This is the perfect child's pedal bike and the price is likely the best on the market. HIGHLY recommended.

The bike itself is good but it came with missing part.

Easy to build out of the box, but not so easy to tune for a good riding experience. Put it together with just 1 adjustable wrench in about half an hour. However some adjustments needed for the nuts of the handlebar and pedal cranks for a smoother experience. My 4 year old boy got riding smoothly after about half an hour of fiddling around and getting used to the arm and leg motions. Overall recommended for parents with some tool assembly and kids with some prior pedalling experience, at ~200 Singapore dollars.

There are no training wheels (the description is completely deceptive), I can't install the reflector because its base which is attached to the bike is missing, there is no installation section in the manual. Unless the company sends the missing pieces and wheels, I will keep this score. The box in which the bike comes is very fragile and with a lot of holes. It would be a reasonable birthday gift. Please look for something else!

Der Aufbau hatte sich schon recht schwierig gestaltet für uns Leien Die Vorderbremsen bremsten nicht richtig. Auch die hinteren nicht. Da das Fahrrad keinen Rücktritt hat sind wir davon ausgegangen das beide Bremsen das Fahrrad sofort zum stehen bringen. Wir haben dieses Rad für unseren Enkel gekauft, wenn er mal zu Besuch kommt. Mit den Stützrädern ist das alles kein Problem gewesen aber als wir die Stützräder abgemacht haben und unser Kleiner alleine fahren konnte war das einfach nur gefährlich. Wir haben einen Bekannten, der ist bei einer Fahrradfirma tätig. Der hat gesagt dass da bei den Bremsen nichts mehr zu stellen geht. Wir sind mega enttäuscht. Berg ab fahren geht gar nicht. Nur mit festhalten. Dieses Rad ist nicht zu empfehlen.

Excelente!! Mi hijo quedó fascinado con su bicicleta y yo muy satisfecha con la compra
