9S Downtube Disney Folded on the water


The Downtube 9S is equipped with 9 speed front suspension. When it comes to a commuter bicycle, this folding bike is our top seller. You will be blown away with this bike and its potential as a great commuting apparatus. Similar to the frame geometry of the 9FS, this baby is exactly what commuters are looking for. A rear rack and rear fender added makes a whole difference because it allows commuters more room. The rack is one of the things that commuters will appreciate because it allows them to haul all their gear.

For additional comfort, we added the adjustable front fork. Looking for a bike that stops on a dime? Consider this 9 Silver Suspension folding bike. The quick release hubs make commuting so much easier.

By designing some of the most resourceful and multi-purpose bikes on the earth, we provide you with the ability to select just how you want to ride. Our folding bicycles can adjust the way that you ride. They provide the performance you need with a portable twist to your experience. During our design phase, we place a lot of emphasis on quality and comfort. We don’t sacrifice the critical elements of a bike. We make it to fit your lifestyle.


We have included some incredible features that include the integrated headset, aluminum frame, rear fender, rack and removable frame protector.

High-end Tektro V brakes & two finger levers are matched with double-wall aluminum machined sidewall rims, meaning that this bike stops FAST, since the brakes can engage on a textured surface. Free standard upgrades include the water bottle braze-on (water bottle cage not included) and headtube bag interface. The bike is fully disc-ready, and we incorporated the disc hubs, which accept 6 bolt rotors, frame tabs for disc, and disc cable routing. A front derailleur braze-on with cable routing allows riders to quickly and easily turn this bike into a 27speed bike. We also add mini-bar ends and high-rise handlebars which allow the rider to customize the fit without any interference with the fold. We use standard bike parts so that when you are ready to upgrade, it is a breeze!

Folding bikes are our expertise. We do it better because bikes come naturally to us. In addition, when designing our bikes, we have YOU in mind the whole time. So why wouldn’t you trust us? You really should! We have your best interest at heart and so does this bike. Buy it NOW and see for yourself. It is time to go for a test ride, but only when you have had the bike delivered right to your doorstep. Order today!

    Great bike, folds down small. It carries all my gear, and the rear fender, rack, and kickstand are perfect.

    After many searches to find the best affordable folder, I found it here. 9 speeds, front shock and many other well designed features for commuting and touring in one single model is very impressive ! Bravo Downtube !

    Better than a Brompton

    Posted by Kevin Wilson on Jul 31st 2016

    After hours and hours of researching folding bikes, I bought a 2008 Downtube 9sp front suspension. It's 2014 and haven't had one issue with the bike outside the normal wear and tear in six years.
    I'm 200+ lbs and jump curbs with no hesitation...still not one issue. The only other folder I would buy is the Brompton, but at $1400...that isn't happening. Downtube still stands out amongst it's competitors six years later. Better design, better build, and the best value folder on the market.

    I bought a 2011 Dahon Speed D7. For a Good price. The bike was hardly used. Not too many Folders in Memphis,Tn.USA.Then I purchased a 2013 Downtube Silver 9 from Downtube online. Yan had the bike shipped in two business days.The difference between the two bikes is like Day & Night! The Dahon rides stiff,makes noises,uncomfortable under geared with 7 speed. and throws chains with it's low end components.The Silver 9 right out the box(very minor adjustments)rode like a Dream. This is a wonderfully designed Bike. I love everything about it. All it needs is a matching front fender.I am going to use my Dahon when I travel on the road.I am going to keep my Downtube at home to be ridden in Class & Style.( It's a Chick Bike) The Ladies go Crazy over this Gem.I want to thank Yan Lyansky.For creating this masterpiece of a wonderful Bike.Thank You Yan!
