Folding bikes need more suspension than regular bikes and we listened to the needs of our customers across the globe. So we are now introducing the Downtube 9FS (9 speed full suspension) folding bicycle! It is finally here and many people are pleased and so will you! For one, it is the model that is the most comfortable compared to our other bikes. It is preloaded with adjustable suspension located in the front and in the rear.

You can take this bike on long rides without needing any more than nine speeds! The bike’s build quality is amazing and solid as a rock! The wide handlebars make it easier to maneuver. You will even forget that you are riding a folding bike, if you are not careful.

Most folding bikes have smaller frames and wheels, which makes them stiffer than larger- wheeled bikes. Our 9FS bike is delivers super comfort and is EXACTLY what is going to work for most riders. You won’t want to stop riding! On top of being more comfy, you will love the high quality drivetrain by SunRace, which we added. We are proud to announce that its performance is similar to that of the Shimano Deore. In addition to the top notch frame with comfortable suspension, we added several high end parts and a small fold. If you could describe this bike in one cool sentence, it would be “This bike rocks!” It has some incredibly amazing features that you will enjoy every time you hop on this bike. It will fulfill almost all of your needs and more…

On this bike, we include features that will make it more enjoyable to go on long rides. You will notice the aluminum frame, rack braze-ons, but rack is not included; integrated headset, and removable frame protector.

Do you want to know why this bike stops FAST? I bet you will love to know that too! Well, its high end Tektro V brakes, two finger levers, which are matched with double-wall aluminum machined-sidewall rims is the reason; since this allows the brakes to become engaged on a textured surface!

We also offer standard upgrades for free and this includes the headtube bag interface and water bottle braze-on, but cage is not included.

AND that’s not all!

With its adjustable suspension, it is so much easier to go up the hill. This bike is now fully disc ready. Yes, you heard right - it is 100% disc ready! In fact, we also include disc hubs that accept 6 bolt rotors. We also include frame tabs for the disc as well as disc cable routing. It also comes with a front derailleur braze-on with cable routing, which allows you to easily turn this bike into a 27 speed bicycle in a snap. Without hindrance to the fold, when you buy this bike, we customize it to your liking by adding mini bar-ends and high-rise handlebars.

When folded, it fits in any size vehicle. You will get tons of attention when riding on your bike. You will be almost obsessed with this bike when you get it. So what are you waiting for? Hit the purchase link and get to riding!

    UNBELIEVABLE

    Posted by Tom on Jul 31st 2016

    One word- UNBELIEVABLE. I'm not joking. I have the 9FS and the bike is simply amazing. I'm already going to order some extra parts, but bought the bike used. Now the only thing I wish is that I just bought it new. That's because they don't lose a lot of value, so you might as well get the newer one. And with the black out bits I think they look more modern. Here's a few impressions I've gathered:

    I read a rant from someone stating the brakes aren't that strong. So I put this to the test. I took it down the hill next to my house that has an easy 50 degree incline- stopped on a dime. I weight 160lbs and thought about upgrading to discs. Why? They work great just the way they are.

    Build quality is great. Solid as a rock. I hear the 2013's are even better, but the 2010 I have can be tightened down perfectly with no wiggle in either the handles or seat post.

    9 speeds work great. I thought they might not be enough, but now I'm wondering why I'd need more. I've taken it on a long ride and can't seem to find any need for extra gears. If your a bike nut, then maybe. But for the average Joe- well, I just don't see how you could be disappointed.

    The handle bars are wide- and I love it. I didn't know if it would matter but IT DOES. It makes it so much more comfortable and easier to maneuver. You completely forget your on a folding bike.

    Adjustable suspension! I thought it might be to soft- wrong again. It's so easy to adjust and felt absolutely perfect even climbing hills.

    It folds fine. Is it the most compact in the world. No- but who cares? Frankly, I can't tell at all. It fits in my Chevy Sonic with a ton of room to spare. For the added comfort of a suspension, I'll take a few extra pounds.

    I'm so happy with this bike that I'm almost obsessed with it. Tomorrow is suppose to be nice out and I can't wait to take it for a ride. I get tons of looks on this thing too.

    Now, time to start ordering all the extra bells and whistles. This is the best bike I've ever owned.

    Great for my sailboat

    Posted by Thomas Perry on Jul 31st 2016

    Dear Sirs It's been two years since I've owned 2 of your wonderful bikes. I am a sailor and have often carried my full-sized bike on my boat to ride when we went ashore to enjoy the area. The bikes where too big and had to sit out on deck to travel which would subject them to the extreme salt air and sea conditions.
    I thought, how much more convenient it would be to have folding bikes, so I spent many months looking around our local bike shops then online for what I felt would be the type of bikes we wanted. I saw all the usual popular folding bikes but was concerned that the small 20" wheels would create a stiffer ride, I read many blogs and decided on the DownTube 8FH brand bases on the feedback I read, it was reasonably priced and comes with full suspension. We have used these bikes for two years now and love them. These bikes are dedicated to the boat only. Its quality built and has a smooth ride, great for the light dirt trails along the coast and the 8 speed internal hub to keep things clean verses the usual derailleur configuration. On my bike I have put on fenders, a front disk brake and a rack on the back with Panniers for carrying extra clothing or for picking up food etc. for the boat. The other I've kept stock. It weighs about 27 LBS. a bit more with the extras added but light enough to carry on your back in the carrying bag while climbing up the ramp from the boat ramps. The Bikes are folded into their own bags and kept in one of our 3 sleeping cabins and supported by a lee cloth. We have no problems getting them through the cabin door, the companion way or into our dingy. They are made of aluminium and built to withstand the sailing environment. We are no longer relegated to staying only around the marinas, but enjoy a daily bike ride to Light Houses, wharfs, farmers markets or city activities. Everyone that sees them says what a great idea and where did you get those? I tell them you can order them on line. For cruisers it's a great way to get your exercise and enjoy the back road sites of out coast line. Thank you for designing a great bike we enjoy them every time we unfold them.

    Solid and comfortable

    Posted by Chris Ihm on Jul 31st 2016

    When I moved to an apartment in Queens I knew it was time to switch to a folding bike. I did a fair amount of research looking for one that was sturdy enough to carry my weight (225), would fold small and be fairly light to carry, would roll when folded, wouldn't break the budget. The 9FS met those criteria.

    I ordered it last Wednesday and received it on Friday as Yan predicted, and the bike was packed well enough that UPS wasn't able to damage it. In fact, after doing the bike-store-style checkup posted on the Downtube website, I was able to take it out for a quick spin two hours after I opened the box.

    Today I rode ten slightly-hilly miles on a multi-use path. The 9FS continues to feel solid and comfortable, and I'm looking forward to many more miles, and a lot more of the fun I had today. That is, if I can keep my wife off of it - I may need to order another one!
