Question: do I need to combinate the bicycle myself?
Document: I love my new bike! It was easy to put together and it rides smooth and takes enough impact to enjoy off road cycling. Of course you will need a better seat because majority of generic seats on bikes hurt you butt if riding for long periods of time.
Other than the front wheel being stubborn getting placed, I am very happy. My butt hurts now but only from not riding bikes for 20 years!
This bike came quickly was easy to put together and looks great. It rides nicely. For the price, I don't think you will find anything better!
I received today the bike, the box is very damaged but the bike is good. It's a basic bike but the price is low... Depending the use I think is a good choice, it is very easy to assemble.
We didn't know that it was going to come in pieces that we would set up. It took us ages and it's not even set properly up yet. Well, I guess we'll have to bring it to a bike shop to be sure everything's fine. Otherwise it looks pretty cool and sturdy. We'll how it goes as time passes by!
Bike works great. Easy to assemble. Only problem I had was the handle bars coming very loose when I firstly rode it. Seat is extremely uncomfortable and will hurt your back if you plan to ride long distances. I recommend buying a gel seat cushion. Other than that, great bike to buy for the price.
My son really likes the bike and I hate to have to take the time to return it, but the tire is warped and it wobbles when he rides it. I would like the company to offer to send me a new tire but if they don't I'll just return the bike and get something else. Other than the tire the bike is great. He loves the shocks and the bike is great. Would hate to have to return it.
The bike is Amazing I use it for food delivery in NYC.The only bike complaint I have is that the seat is painfully stiff and that the handlebars took a while to adjust but that was on a related issuerelated issue - I got the bike used and Amazon's odd customer service didn't send a peddle or the bolt that tightens the handle bar to the handle bar stem but fortunately i got those from Huffy.
Received it today. Box was torn up and already opened when it got to my front door. The parts looked to be in OK shape. Took an hr or 2 to assemble. Once assembled, I took it for a ride. I noticed the gears that the pedals are connected to are spinning crooked. I could not switch gears properly and then I noticed the tires are not spinning aligned either. You can see a wobble.
This is my first mountain bike. I was surprised by the way the nose dips on its shocks when braking. If not careful, it could cause a flip. The seat also is less than comfortable. Other than that, I find it easy to ride, shift gears, pedal up hill & down. When I get into a little rougher terrain it is more difficult to control due to the front shocks taking too much of a dip & causing a possibility of a flip.
Answer: no
