SE Big Mountain 21 29er Mountain Bike
The SE Big Mountain 21 29er mountain bike provides an affordable means to hit the local trails or your favorite greenway with aplomb. Its steel frame is incredibly strong and provides a nice ride quality over the rough stuff while the 75mm travel Suntour suspension fork smooths out ruts and roots. The 21-speed drivetrain delivers the perfect range of gearing so you're all set for climbing as well as rolling along briskly on flat terrain. The 29" wheels provide the means to roll over obstacles better than smaller diameter wheels and they roll super smooth on smooth terrain. And when it comes to controlling your speed a set of linear pull brakes ensures you've got all the stopping power you need.

  • 21-speed drivetrain offers a wide range of gear options to help you over hilly terrain

    I like the bike and it was a great deal. I got it for gravel road and trail riding and it works great. The seat was unconformable at first but now its fine.

    Comments about SE Bikes SE Big Mountain 21 29er Mountain Bike:

    The front forks NOT adjustable and are a little soft. The saddle and seat post are lower quality. The value is excellent. Nashbar price and price match are great.
    The bike comes in a box with cables attached to the handlebar. Assembly is simple. Do not select a dimestore bike just because you are not wanting to assemble. The other feature is the rear cables run on top of the top tube. I had a 3 year old Fuji 29er and it needed several parts. I am very satisfied with this bike. (I ride around 400 miles a month)

        For the price I found this bike to be an incredible bargain. I was able to get my 13 y/o son into an entry level mountain bike for a very reasonable cost. After a month everything still works great. The bike is a little heavy, but other than that he loves it. Mostly used for riding gravel backroads.

        I have pro level road bikes and wanted an entry level MTN bike. For the price this bike cannot be beat. I read the other reviews and they are harsh. I had this bike from box to riding in an hour. I did completely flip the brake/ shifters opposite of how it came. I replaced the seat stem and seat for my comfort and I could have used 21" frame but the 19" is adequate with the longer seat stem. Everything works great on this bike once tuned and I do recommend it. It is heavy for MTN biking but suits the local trails here fine.

          This is my first bicycle purchase besides aa brick & mortar store. I bought this model for its price and expected durability in a small town. It is very comfortable, but I have to admit I haven't pushed its capabilities yet. Clearly worth it for commuting.

          Comments about SE Bikes SE Big Mountain 21 29er Mountain Bike:

          This is a great bike for the money. Astute viewers may recognize that this is exactly the same bike as another sold here, with a lower price and a different color/decals. I'm 5'11" an bought the 19", although I could have gotten the 21". Bought on a Nashbar discount promotion, this bike costs the same as big-box store bikes of similar quality and maybe even less. The purpose of this bike for me is to have a bike handy at work, that I can lock up outside and not worry about. Mine came with a Zoom fork, which appears to be the same as the Suntour with different stickers. Crank is alloy or steel but entirely ensconced in a fused plastic clamshell, which is kind of weird and interesting. Components are better than the price would suggest. Assembly and adjustment was easy, the only vexing item being the orientation of the derailleur hanger on the frame which I figured out quickly. Frame is hi-ten steel and heavy, but tank-like in a good way. Welds look like hammered poo in places (a term you'll know if you're a welder or know someone who is), but the penetration is good and I have no cause for concern. There are eyelets for a rack and fenders on the rear dropouts, but strangely none on the stays, so if you want to mount a rack you'll have to be creative. Brakes are fine, the front is particularly effective, and the rear feels a little like pulling a sinker through a bowl of oatmeal. This a good runabout bike you don't need to worry about. It would not make a good mountain bike, as the gearing is too high and the fork is inferior for trail work, plus it's heavy. But for running around, exercise, and not having to worry about it, it's a great bike.

          I will use this for some commuting and light off-road. Assembly was easy and pretty straight forward. Seems to be a good quality bike for the money paid. Only problem so fair is that the brakes squeak when applied. Hopefully this will go away once broke in.

          Bought this for the (discounted) price only. Assembly was straight-forward. Derailleurs were well adjusted and didn't need to be tweaked. Small thorn punctured tire on maiden trip around the block. Buy a bottle of slime for your assembly list. This will work good for casual riding, but won't last long on the rough stuff.

          This was purchased as a gift for my son as his introduction to quality bicycles. I had hoped it was a quality bicycle. The wheels needed truing when it cam (expected) but the fact that they wont keep true is very frustrating. The brakesare a joke and will have to be upgraded to a quality set from our LBS. The brakes feel spongy and the brakes bend when used hard. I'm very dissapointed and will never buy another or recomend to anyone.
