Question: my wife is 5ft 7inches. is this size (15) ok?
Document: Great bike! Bought this for my wife so she could keep up with me on my Trek. Took about 30 minutes to put together but was not hard at all. We ride often on paved and firmly packed dirt bike trails and the bike handles well.
The bike is for Christmas and is currently being hidden. I have not opened the box it came in.Diamondback is a quality bike, I am sure that my wife will like the bike. I am not happy that the bike was reduced in price for black Friday by $50.00 and I was unable to recover the difference. Instead I was offered a $10.00 credit. I feel that I was taken advantage of.
I was looking for a comfortable upright bike, and after spending about 100 hours researching bicycles online, and speaking with a bike salesman at our local department store (who was very helpful), I decided on getting one with the larger 700c, rather than the 26&#34; mountain bike size tires to make peddling more efficient.
Very comfy ride. I looked at much more expensive bikes, and granted I don't ride 20 miles a day, but this one has worked wonderfully for me.
Today, I received a refund in full and they didn't charge me for the shipping. Amazon gets five stars!
This was purchased by a friend of mine through my prime account. It was already 90% assembled when received and the rest went together like clock work. The front and rear derailleurs needed practically no adjustment and I am no experienced bike mechanic. Wouldn't highly recommend this product to anyone.
This purchase has turned into a not so pleasant buying experience.
This is a great bike for someone who is both serious about riding but not ready to buy a high-performance, high-cost bicycle.
This bike is perfect for me. I am an adult woman who hasn't ridden a bike since childhood and is looking to commute to work on a bike starting this summer. This bike is comfortable, easy to ride, the gears shift easily, it was extremely easy to assemble, and it does everything I would want. It is light enough to lift but the tires are substantial enough to handle mildly rough terrain. And the price was really great.
These tires are about half way between a road bike and mountain bike in width and are pretty smooth with some tread, but they are not knobby. Basically, this bike is a cross between a road bike, mountain bike and comfort bike with 21 gear speeds.When I opened the box it came in, I didn't think I could put it together, but decided to just do one thing at a time, and after 2 days, I had it assembled.
Answer: no
