Diamondback 2012 Insight STI-8 Performance Hybrid Bike (Black, 17-Inch/ Medium)
Product Description
The Diamondback Insight STI-8 takes the high performance and versatile Insight 3 and turns it up a notch. By adding simplicity in use and maintenance, we've bettered our top of the line performance hybrid with a Shimano Nexus internally geared 8-spd hub and single front chain ring. This leaves you with better shifting and an easier to maintain rig. Add in a Shimano 8 spd, twist shifter and what you've got is one stealth and simple machine that packs a punch.

Great ride around bike
By R. J. Bennett
This is a great affordable bike with internal gearing. This is the main reason why I bought this bike. I wanted a simple, maintenance free bike that would be fun to ride for 15 to 30 km at a time. Build is excellent.PROS:1. Super quiet2. Light and nibble3. Great gear rangeCONS:1. Brakes are not great at stopping the bike2. Brakes are noisy, I think I will upgrade at some point3. The tires slow the bike down, I think they should be narrower and higher PSI for a faster ride.Saddle could be better but at the price point and my expected riding distance I won't complain. I have other bikes for longer or faster rides. This bike is a great commuter or go ride the neighborhood kind of bike.

Impressive quality, but check out the Incredible value
By BD King
I would have gone to five stars just for the value, but there was no sizing guide, hence the 3 stars.I bought this primarily due to the Shimano Nexus hub and other reviews. The bike came on schedule (as always with Amazon Prime), and the quality is impressive as you remove it from the box. As with other reviewers, I decided to let a bike shop do the final assembly and tuning. The instruction manual leaves a lot to be desired for instruction, and there are nuances to tuning a bike that I believe are better left to the bike shop mechanics.A couple of things:1. The seat is a torure rack. Immediately replaced.2. They don't tell you how to "size" the bike. Once I got the manual, I realized I should have ordered a medium, not an extra large. The extra large is about 2-3 inches higher than is comfortable for me, but I'll keep it anyway. Check out your inseam and order the correct size.3. The tubes use a valve that is incompatible with 'standard' air chucks. You'll need adapters or a pump with that nozzle.4. No kick-stand. That was a significant dissapointment.ValueEven though I paid $50 for the assembly, another $35 for a gel seat, $10 for a kickstand and valve adapters ($5), I found out after the fact just how much of a DEAL this is. The shimano nexus hub sells for over $350 by itself, and I got this for a total cost of $479. Add the other costs and I've out $579 for a high quality, light weight hybrid bike with a state of the art internal hub. I checked around, and there is no better deal anywhere for this combination.RideThe bike rides excellently. Once I got used to the height. I love the internal hub: this was not my first experience with internal hubs. I have a Sturmey-Archer 8 on a TerraTrike Rover 8. I much prefer internal hubs to derailleurs. You can shift even when stopped, there are no clunky adjustments, and no endless chain adjustments. Even though you "only" have eight speeds as opposed to 27 on derailleurs, I find that this is adequate for all but the steepest hills. As a rule, I seldom used the higher gears on my 24 speed, and used the very low gears even less.You can add a Patterson Metropolis Transmission in place of the front crankset if you like ($250), and that increases this to 16 speeds, providing a little better low end, and you still have an inexpensive bike for the quality and capabilities. If we start riding more hills, I'll likely add that in the future.

By DMont
I got so sick of dealing with derailleur problems and adjustments I set out to find an internal gear hub bike. Unless you want to spend over a grand this was really the only thing I could find. I didn't have any experience with internal gears before this but after using this bike for a while, I'm never going back to derailleurs, at least for everyday commuter.Shifting takes a little getting use to. It's nice being able to downshift while braking into a corner, and being able to come to stop in 8th gear and just click it right back to 1st. Unlike the old 3 speed internal hubs, you can up-shift no problem under light pedaling. Under heavy loads like trying to downshift while going up a hill you might have to pause pedaling a moment, though this really hasn't bothered me much. Under normal conditions shifts are so fast and smooth you'll wonder if it really happened. I did somehow get stuck between gears once, but other than that no problems to report. There is quite a bit of gear friction in the hub, your turning a lot of gears even when you’re not using them. So maybe there's some sacrifice in efficiency but it's not really noticeable to me.In all except very steep hills the 8 speeds is all you'll ever need. I'd say 1st gear is probably about the equivalent to a 3rd gear on your standard off the shelf 21 speed. If you think you need that granny first gear then maybe this isn't right for you. On mostly flat ground you'll be in 4th or 5th gear most of the time.Quality of the whole bike is a step up from your average inexpensive bike. Not top quality components but definitely not the cheapest either.I'm 6' tall and the 19" is pretty compact for me. As slim as it is, I find the seat fairly comfortable.Brake pads could be better. I can't stop my fronts from squeaking. Hand grips are really nice, but they keep rotating down.The ride is surprisingly smooth and compliant for an unsuspended bike. It's nothing like an old, steel frame 10 speed.If you know nothing about bikes you'll probably want to have it assembled for you, but really basic knowledge is all you need to do it. The back wheel and chain are all pre-installed, which would be the hard part. Make sure you check the cable adjustment on the shifter, took mine for the first test ride and gears were slipping all over the place. Instructions detail the procedure, it's pretty simple. Once it's done you're pretty much set.
