Question: i want to buy a tube and tire can some guide me
Document: It took me three hours of riding time to pop an inner tube (but that was my own fault for having a 3/4-full tire and going over railroad tracks). This bike has some giddy-up. If you hate attention, this bike isn't for you... people look at this bike like Oprah looks at a Christmas ham. I haven't been able to take it off any sweet jumps just yet, but I did ride it up a humorously-steep hill I'd never known existed.
The bike arrived on time, packaged well with Schwinn box inside a bigger box for good protection. The build was straight forward taking about an hour including unboxing and a quick scan of instructions.By the way good instructions on YouTube for adjusting brakes and detailers, just search bike maintenance.Now for the problems faced. I inflated the rear tire to about 80% the recommended 125 lbs and was starting on the front when the rear deflated in 1 second from a split tube.
I only had one issue, and they resolved it right away.Don't hesitate to buy this one bike.
The freewheel has some grooves on the surfaces of the cogs. The teeth of the cogs are irregular and appear to be worn. The gear will not shift into its lowest gear or the largest cog. My barrel adjuster on the derailleur does not turn easily at all. While the rim and tire themselves do rotate with no warp.
I've had my Schwinn Phocus for about 2 weeks now. I've never written a review on here before, but I am so happy with this bike, that I had to say something, especially for those looking to get into biking and not sure what to buy. I have not been on a bike in about 20 years or more, and I now I'm addicted.
So in sum, Schwinn has offered to the novice to modest rider the opportunity to enjoy 1999-2003 race quality (again only a few adjustments or tweeks would be needed) with a touch of 2014 design at a modest price. In other words, Superb...Schwinn. Very happy that I bought it. There is a learning curve with assembly. There are tools to have or buy if you do not have them.
I just got this bike for my husband and he already loves it. It's a good value for those who want a nice bike without paying outrageous prices. I'm not impressed and was quite disappointed by the fact that we received this (new in packaging) with parts of it badly scratched. Even though we removed protective cardboard from the shaft, we found scratches and gouges, that go completely through the paint.
The bike was hard to put together, though I'm not great at assembly. It was missing a part for the front wheel and had to order that. I actually brought the bike to a bike shop to make sure it was put together so it was safe, which cost more money. It wasn't a great idea to buy a bike on-line, wouldn't do it again. The bike looks great, however! Would have sent it back if it was easy to do.
I love my bike, it performs great. My speed and time has increase drastically from a lightweight mountain bike to the Schwinn Phocus. I am a advert biker and I do a lot of cardio training and this bike is perfect for it. By the way, this is my 1st road bike. It fits great. The only problem is I have been having is that the inner tubes are too thin and don't hold up to long rides. I brought a heavy tube and cant wait to try it.
I haven't worked on a bike since I was 17, and now I'm 54 so didn't want to take the chance of something falling apart. Once I got going on the bike, it was fantastic. It performs incredibly well. I'm 6 feet and the bike fits me just fine. I didn't like the pedal stirrups at first. I felt like my feet were confined, and that I could not get them out of the stirrips fast enough when I stopped.
Answer: yes
