Review: Gravity 27FIVE SS 27.5 (650b) rigid single speed mountain bike
I recently purchased a Gravity 27 FIVE SS 27.5 (650b) rigid single speed mountain bike. For $350.00, no tax, and free shipping, I figured the Gravity 650b was a great way to experience both 650b and single speed without spending a lot of money. I’m very happy with this bike. It’s a quality bike and lots of fun to ride.
The bike shipped with no problems and arrived in good condition. I had no problems putting it together. I love the simplicity of the single speed, as well as the direct power it delivers from pedal to rear hub.
This is the first 650b I’ve ridden (and owned) and it fits me very well (I’m 5′ 8″ with a 33″ inseam and I got the 17″ frame). The good fit of the 650b makes the center of gravity much lower for me than my 29er and I found the bike a lot more maneuverable and playful than my 29er, which was something I was looking for in a 650b.
I added better and wider tires to my Gravity 650b (Kenda Slant Six Pro) as well as better pedals (Diety Compound) and grips (Ergon GE1). The seat the bike came with (a WTB Speed V) is comfortable and I have no need to change it.
The bike rides well and I’ve enjoyed riding it. I’ve had to get off and walk a little more often than usual, but not that much more often than usual. I ride in the mountains and I have to walk my multi-speed 29er pretty often too. It’s nice riding a bike without thinking about changing gears. And it feels a lot better than a multi-speed when you have to stand on the pedals going uphill, too, which is pretty often.
Without a front suspension fork the ride is a bit more jarring at times, but not that much more (it can be pretty jarring at times on my hardtail too), so I have to be a bit more careful to watch where I’m going. I like the rigidity of the fork when I’m climbing uphill, which is more often than not, and I’m going to experiment with lower air pressures in the front tire to compensate for the lack of suspension.
All in all I would say the Gravity 650b rigid single speed is a great bike for those who are looking for an entry level 650b rigid single speed mountain bike. For the price, quality, no tax, free shipping, and fun, it can’t be beat!😀

Why ride a Singlespeed?
“Modern 24-27 speed bikes are marvels of technology, and allow a cyclist to select the gear ratio that will make the most efficient use of his/her energy. If what you’re after is getting the maximum possible speed/distance for the minimum effort (and there’s nothing wrong with that!) a multi-speed bike is what you need…but, efficiency isn’t everything!
“If you’re riding for sheer pleasure, or for exercise, you don’t necessarily place that high a premium on output results, as measured in speed, distance or vertical climb. Instead, you may care more about the actual experience of riding your bike. In this case, you may be a candidate for a singlespeed bike.
“Riding a singlespeed can help bring back the unfettered joy you experienced riding your bike as a child. You don’t realize how much mental energy you devote to shifting until you relinquish your derailers, and discover that a whole corner of your brain that was formerly wondering when to shift is now free to enjoy your surroundings and sensations.
“Paradoxically, a singlespeed is, in another sense more efficient than a multispeed bike! While the single gear ratio will not be the “perfect” gear ratio for all conditions, in the conditions which fit the single gear, it is considerably more efficient mechanically than the drivetrain of a derailer bike.
“A singlespeed bike dispenses with the weight of the derailers, shifters, cables, extra sprockets and longer chain. In addition, a singlespeed gear train runs the chain in a perfectly straight line from sprocket to chainwheel, and avoids the serpentine wind through the pulleys of a derailer. You can really feel the difference! A singlespeed is noticeably quicker and easier to pedal than a multispeed bike in the same gain ratio.
“Singlespeed bikes are also considerably more sturdy and reliable than multispeed bikes. There’s no derailer to bash if the bike falls over, catch on the underbrush or to get overshifted into the spokes. The rear wheel itself is a lot stronger than one made with off-center (dished) spoking to make room for a whole bunch of sprockets on one side…”
