Carbon full suspension BMV


Cheap carbon options from China


Their business practices are shady, their English worse, but they almost own manufacturing in the World.  Already making bicycle parts for name brand cycling companies, now these factories have turned their expertise to making their own in-house bicycle parts for much less money.

These parts have all the technology behind them as workers already make parts for their high-end customers.    What is lacking is all the media hype and research and development seen in brands you already know.


The above bike frame is a near replica of a Scott Spark, their high-end full carbon race bike. The geometry is identical, but they take design tips from other brands and incorporate them, such as the "handle" at the seat tube/top tube junction seen on many Specialized bikes.


This bike was purchased from a China seller.  The main difference is in the price as the ride and weights are near identical to their near-cousin name brand versions.

Already this test frame has been put through the paces on some of the southeast's most demanding trails and has put smiles on the riders faces.  The frames are offered in 29 and 27.5 inch wheeled versions as well as hard tails.

In a time where carbon bicycle components and frames are seeing sky-rocketing prices riders still want to protect their wallets.  The name-brand frames are not US made; the money goes over seas anyway, but these cheap alternatives are cutting out the middle man and giving the bike shops a source of reasonably priced bicycles.

I call it BMV because the ride is so sweet you will want it to be your Valentine too.

Update:  I have well over 7,000 miles on this frame and with no issues.  I have serviced the pivot bearings once, and the ones lower on the frame needed it, as is common to all frames.
My only complaint was in the initial build I could only arrange the front derailleur high enough to fit a 38 tooth ring, but this is no longer an issue with 1x11.
I have just replaced the chain stay portion with a new thru-axle chain stay, and this has stiffened up the rear end a little.

Update II: I rode this for 3 years, racing and riding, but retired it when I got a new bike.  The parts have been swapped over to a 120 travel frame of the same factory and that one has 10,000 miles on it from all over the country and still going.

The cable routing is wrong.  When will frame makers realize that the cables from the right side of the bar route around the left side of the frame, and the ones on left to the right?  This also has the rear brake as an internal routing through the frame and the derailleurs external.  I do not route the brake internally because that requires disconnecting the hose and finding new parts to re-connect. Instead I routed one of the derailleur cables through, and this is not the smoothest of routing lines, but works just fine.  I then attach the brake hose externally where the shifter housing went.  It works, but smart riders have been routing cables smoothly around the other side for over 20 years now.  Come on guys….

  1. What an amazing design of this bike. I really want to suggest you for this bike you should use carbon fiber bike frame which is lightweight and easy to riding in mountain.
