GRZ700 Road Bike, 700c Men's, 21 Speed

My fiancée loves her bike! It arrived fast, and was free of shipping damage. It was relatively easy to assemble once I had the correct tools, and is good quality for such a low price. From a more technical point of view, the bike is a little on the heavy side considering its only medium sized. The dual set of brakes is a hit for my fiancèe who doesn't like to always be reaching for the drop brakes. The shift levers are a bit far back, but considering the brake set-up, it makes sense. For the price, this bike is a great buy, and even though it's not a top of the line road bike, it is more than enough to get you outside and enjoying cycling.

i have a mountain bike and wanted to bike on the road ,bought this thinking it would give better performance and i can ride faster on the road. It does but very little boost compare to mountain bike. Its a good bike but if you are looking for a performance one this is not. Also, changing gear is not smooth and makes noise and have to constantly adjust the front and back to make the noise go away whenever changing the gear. also wasn't able to go all 21 speed, certain combination of front and back are not possible to do. couple of time chain got dislodged during the uphill chaining gear making it dangerous.Tried to call the vendor but put me on hold for a long time and i gave up.

I biked about 2k miles last year with my Walmart $100 MTB, mostly on a paved trail. I bought this road bike about 2 weeks ago and had about 120 miles on it. So far I am neither happy or unhappy with it. Here are my initial thoughts on this bike:Pros:1. It is a lighter bike than my MTB, though it is still about 30lbs. Tires are thinner and can be inflated up to 85psi. All these result roughly 10% gain on speed with less effort to pedal compared to my MTB.2. Dropped handle bar gives you more options to position yourself against the strong wind.3. Easy to assemble. I just need to true the wheels and adjust the brakes and shifters.Cons:1. Seat is not comfortable especially during a long bumpy ride.2. No bottle holder or threaded holes for one. You need to buy the holder separately along with a tap bit.3. The derailleur shifters are mounted on the stem. It is not that practical if you need to shift constantly.4. The front derailleur shifter does not have “catching mechanism”. It is like a linear pull where you have to estimate the catching positions of each of those three front gear rings. Luckily I don’t need to shift it that often.5. Tech support wasn’t available at the time I called two weeks ago. I left my phone number and have not got a call-back.Bottom line: It is a great cheap bike for commuting on a flat road. If you bike to exercise, you might need to ride a little bit longer to burn the same amount of calories than on a heavier bike.

I bought this bike to prove that to ride fast and showing good time you don't need expensive bike. Buy it was easier that i though :) Bike came in good condition, everything works. Breaks are kind of ok, but they work (must use both). Only thing i had to change right the way is the front sprocket for a bigger size.Had this bike for 150miles of hard riding, so far so good. I'm very impressed that it works so well!

Didn't come with an Allen for assembly or the screw to hold the shifter on. Also, the cover on the sprocket broke the first ride. Other than that it's good for the price.

This bike ain't the best out there. It's definitely a budget bike. As far as looks go this thing is a looker but actually using it is a different story. If you're mechanically inclined getting this thing together isn't rocket science. But adjusting the poorly constructed brakes takes some time. After the better half of a day adjusting the brakes to get more stopping power I finally came to the conclusion the brake pads this bike came with are garbage 1/10 no bueno. They're made from this soft rubber material similar to the consistency of a pencil eraser that has poor bite on the rim of the bike. Riding it is pleasant. I was able to get some speed relatively easilyBike maintainss it's momentum as it rides. Shifting through the gears isn't the best. Not really a fan of the lever type shifters but it gets the job done. Quality feels ok, and as far as durability it's not good. After the first ride the bike fell apart and became unusable, via an issue with the rear wheel hub. Overall for the price they're asking if say it's not worth it. Had to wait a month for the bike to get here due to a lack of inventory. Definitely not worth the wait. Super disappointed. I am glad Amazon is making it right with a full refund but still can't help being bummed out after having waited so long for it.

I purchased this bike back in March to commute to work 17 miles a day round trip in NYC. In honesty, I bought this as a quick fix to taking the subway during the surge and peak of our Covid outbreak with the expectation that I would purchase a better bike after a few paychecks. However, this bike as surpassed my wildest expectations and has performed wonderfully. Durable and comfortable, I've ridden almost 1000 miles at this point with no degradation issues. Normal maintenance is required of course. The gear shifter is not as precise as advertised, but at the price point, can you really complain? I can't speak to other's experiences, but if I was faced with the same decision again, I would purchase this bike without question.
