Question: I always get a flat tire wit this bike.I mean i cant even go 3 miles before the tires give up.I changed the tire tubes many times ?why?
Document: Paid the less than $3.00 extra to get this in 1 day. I had the bike 98% done except for a couple of adjustments in less than an hour. It looks great and went together very easily. After putting it together,put the chain on the front sprocket, adjusted the front brake, air in the tires and rode it. Now the true test when my Fiance rides it this weekend. So far so good.
I LOVE MY BIKE! I have had this bike since 2008 and I get stopped and am given compliments on it all the time. I have been told it is a great fit. It runs great. I exchanged the tires for commuter tires for about 20 dollars, and I ride it on average 8-16 miles per day. I also exchanged the seat for something a little more comfortable for really long rides. The seat that comes with it is perfect for the average rider.
The shock and components on this are designed for easier going stuff.Oh - and assembly was a cinch. Put the tires on, put the handlebars and pedals on - nothing advanced. I did have to tighten the brake cables a bit but that's always the case with a brand new bike. If you aren't sure, you can always lug it to your local bike shop and have them dial everything in for a nominal fee.
My bike arrived on time without dings or scratches. It was mostly assembled already except for the seat (very easy) the pedals (very easy), the handlebars (easy), and the front wheel (took some effort) I had to shift the brake levers a bit for comfort for my tiny hands. After that I just tightened every bolt I could find, inflated the tires a bit and then it was ready to go.
This bike is s$#! I can't go from 1st speed to 2nd speed, but I can go from 3rd speed to 2nd speed-wtf? Now I will have to take it to a bike store and have them try to fix it for me-more money that I should of spent on a woman's Trek bike(had one before and had NO problems with that one of  course I spent $500) Do not buy this unless a guy in your life or even you know how to fix bikes!
I even get a good compliments...easy to assemble!really good bike for it is Schwinn and you can never be wrong!
I just got this bike for my birthday and its great. The gear shifters are easy and the gears switch nice and easy.The brakes are amazing.The frame is so lightweight which is great for transporting.The front shocks work better than expected, they really make for a smooth ride especially on gravel terrain. You dont have to work that hard in order to go fast, the gears are so easy to change from hills to flat areas.
Since it seemed to be shifting well enough without me on it, out of fear of messing it up I didn't do this and went to ride the bike.I fortunately didn't have any accidents on account of not making all the needed modifications from the get-go. The handlebars would come loose after a while, so I began to carry an Allen key with me. But after the third time I tried positioning them so the brakes would be further down, and the handlebars haven't come loose since.
i got the bike earlier then the recomended time. it fits me well. im 5ft 3 but it would be good for anyone taller or a teenager. my boyfriend took a whike to get all the gears working properly but it was super quick to put together. i paid around 320 on the bike but the seller bought and shipped from walmart at a price of 199
Brakes &gears needs adjusting from get go.Crank came loose next,need to buy pully for that.Schwinn Made by Pacific now.
