As far as the bike itself goes, this is almost my perfect bike. The candy apple red paint job really pops when you see it in person, and the whole bike just looks really sharp. You never out grow that shiny new bike feeling. The Acera 8 speed rear derailleur is top line quality and will give years of reliable service. The Tektro mechanical disc brakes are preferible to more expensive hydraulic brakes in my opinion, and work great- you'll never be satisfied with vee brakes again. The 22 tooth chain ring up front and 32 tooth cassette give you a nice low gear when most other manufacturers are cheaping out on their gearing. If you want a super low gear it's no big deal to switch out the cassette to a 34 tooth. Last year's Overdrive had a cheap bottom bracket, but the '17 has sealed bearings. The pedals are just fine as are the handlebar grips, but most people will want to replace the saddle. The tires are fine but most people will want to switch to flat resistant tires. I use the bottom end cheap 2.2 Continental X KIng or Trail King tires that don't claim flat resistance but actually are flat resistant in my experience. (Of course you can always spend more for Conti's "Pro-Tection" tires and get the best. 2.4 width tires are too big and will rub the front derailleur.) The frame, rims, front forks, handle bars, and cranks are all solid quality and will perform well for the non-hardcore rider. The one part I take exception to is the Shimano shifters which seem to be an industry standard. I always switch them out for Sram grip shifters.
I also have a 29er and 26" mountain bike. I no longer see any use for 26" mountain bikes as the 27 1/2 (650B) wheels just work better in every way. 29ers have a lot of baggage like poor maneuverability, not very low gearing for hills, and are just plain big and heavy. 29ers have their uses, but the average rider will never regret having the slightly smaller 27 1/2. Note that this bike has no lower mounts for a bike rack which makes it almost impossible to mount one. Some other Overdrives like the 27 1/2 ST do have mounts, so look very carefully at the photos to make sure you know what you're getting.
Amazon pricing on bikes is chaotic. I highly recommend getting the Keepa extension for Chrome or Firefox which I used to get my two Overdrives for $195 apiece and free shipping. I've tried other price comparison apps and extensions and ended up really hating them. The $195 pricing was probably an algorithm anomaly because it only lasted for about four hours, but sub $300 pricing seems to come around a couple of times a year.
Internet bike retailing looks like it's gaining traction, and Diamondback has really hit a sweet spot with the Overdrive.
The 27.5" tires make it much easier to go fast with less effort and traversing rough terrain is made easier as well. The gear shifters are amazing. Nicest gears I've ever seen on any bike, hands down. They are super responsive and quick so switching on the fly for hills and what not is not an issue at all. Brakes are fantastic as well. I recommend looking on Diamondback's website for a sizing guide as I read some conflicting info. One of the comments here suggested for my height I'd need a large, but that would have been way too big for me. I ordered a small frame (I'm a 5'6" female) and I have about an inch of clearance over the bar when standing. Anything larger and it would have been unwieldy.
The grips are really nice as well, though can get a bit rough on the hands on long rides. I took her for a 14 mile trail ride last week and my hands were a bit sore at the end. Rather than swapping them out, I opted to get some nice padded bike gloves. The handles have great grip, they are just a little too abrasive for more delicate hands. The weight of the bike is amazing as well. It's much larger than my previous 26" bike, but is far lighter overall thanks to the fluted frame. Where I would struggle to get my old bike up on the rack, this one I can easily lift and handle without issue.
The only area that needed improvement was the seat. Ouch! Very hard on the rear end. I ordered the Diamondback pillow top seat, which are available for female and male, and it's a huge improvement. Much more comfortable and no more soreness after long rides. Do yourself a favor and order a replacement seat when you order this. Well worth the investment!
Overall I'm extremely pleased. I'm looking to get a few more Diamondbacks for my husband and son as well.
