Folding bikes have smaller triangles ( which means the frame is stiffer ) and smaller wheels ( which absorb less road shock ). This forces the rider to absorb all the imperfections in the road which is not "fun". hence folding bikes need more suspension than regular bikes and we listened. Wwe are now introducing the Downtube 8FS (8 speed full suspension) folding bicycle! The suspension is super soft and comfortable to ride....everyone loves this bike. The suspension is preload adjustable in the front and rear. It shares the same frame and fork as our top selling 9FS, but we configured it with less expensive components to keep the price under $350. It is one of the few folding bikes under $400 with an 8sp cassette, most folders use freewheels in this price range. Freewheels are not at the same quality level, so make sure to get a bike with a cassette to get better shifting.

You can take this bike on long rides without needing any more than eight speeds! The bike’s build quality is amazing and solid as a rock! The wide handlebars make it easier to maneuver, and the angle adjustable stem allows a custom fit for both tall and short riders. 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 8FS bike 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 Microshift, which we added. In addition to the top notch frame with comfortable suspension, we added many 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.

We also offer standard upgrades for free such as the headtube bag interface pump interface, and water bottle braze-on, but pump and cage are not included.

AND that’s not all!

With its adjustable suspension, it is so much easier to go up the hill. It also comes with a front derailleur braze-on with cable routing, which allows you to easily turn this bike into a 24 speed bicycle in a snap. The angle adjustable stem, and bar ends are a great addition to allow an easily customizable fit.

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

    Wonderful bicycle - Better than expected

    Posted by Don Herfert on Sep 4th 2017

    Great bicycle. The suspension functions quite well, brakes function well. The gearing is just right. Build quality is excellent. Easy to fold and lift. Highly recommended. Am looking for a rear rack - any suggestions?

    Smooth on bumpy surfaces

    Posted by Alex Korolev on Sep 4th 2017

    Just have bought 8FS. It is my second bike from Downtube. Riding on bumpy surface I can feel a difference. It's worth it for me to have a full suspension bike. Although for my girlfriend Nova is better because of a lighter weight to carry.

    Good Bang for the Buck for My Purposes

    Posted by Jim on Sep 4th 2017

    I'm not a bike expert but I am quite satisfied with the 8FS. Bought this bike for casual recreational cycling. My observations after owning 2 weeks are as follows: Fast seamless delivery. Fairly easy and minimal assembly Great quality for the price. Looks pretty cool, modern and 'hip'. Rides very nicely with the the front/rear suspension. Seat is comfortable for me. (Apparently some owners change the seat however.) Gears work fine. Not exactly ultra light-weight for a folding bike but acceptable I guess. Compact - Fits into my mid-size SUV with tons of room to spare. My rear brake needed adjustment as it was rubbing agains wheel. Folds ok. Good customer communication service with the Downtube company. So, overall I'm pretty impressed with the 8FS. I think it was a good investment for my situation. If you purchase, I highly suggest bringing your new 8FS to a bike mechanic immediately after assembly for a safety check, minor adjustments and peace of mind. I did this and it ran even smoother after it got the professional once-over. Tip - Surprising to me.....my bike mechanic said that the 8FS bicycle chain did not need to be oiled/greased when I brought it to him after assembly. Apparently the chain already comes coated with a special wax. Good luck with your research! It sure pays to do your homework when purchasing a folding bike..

    Best Bike for the money

    Posted by Paul L on Sep 4th 2017

    I found this manufacturer by accident while looking for reviews of other bikes. I was surprised how reasonable the price was for a light weight alloy bike with good quality components. I need the bike in a rush fora trip and they shipped right out. compartment. The full suspension gives it a soft ride nice for us old guys. Everything was adjusted and worked great, no fussing with derailleurs, shifters, or brakes! Fit nicely in the motor home storage. It does not come with a kick stand and they were out of stock at Downtube but the local bike shop had an EVO adjustable one that works fi ...Read More

    Loving my Purchase

    Posted by Kathleen B on Sep 4th 2017

    I was hesitant to spend so much on something like this online, but I'm glad I took the risk! I've been wanting a bike for awhile but never went through with buying one bc of storage issues. When I found out there were folding bikes in my price range, I thought it would be fun to finally buy one. This bike suits my needs very well. I mostly use it for pedaling around my college campus. It's small and maneuvers well around people and pathways. I can pedal very slowly and still stay upright with the lower gear settings. It's also performing well on the hillier bits of campus and the bumpier stretches of road. It's easy to shift and pedal and the small size gives it a certain element of safety in busy places and at crosswalks. It also folds small enough to fit in the trunk of my mid size sedan, where it stays most the time. This bike is sleek, comfortable, sturdy and feels well made. (Had it about a week and been riding everyday) The reason I gave the bike only 4 stars is the ease of folding. I was frustrated at first with the difficulty in folding and unfolding. I have now gotten the hang of it, when opening, I have to use my weight as leverage to get the lock to shut, and when shutting I have to use a small object (I've been using a car key) to pop the latch back out. (This probably isn't such a bad thing overall bc it seems like it would be almost impossible for the bike to collapse while riding.) The bike is heavy and shifty and doesn't seem to lock in the folded position, so moving it around can be bothersome. Since I can easily latch up the unfolded bike to any rack around campus, this hasn't really been a problem. However I would not recommend this for an older person or someone planning to fold it up and port it around by hand. Maybe there is a way to lock it shut, which is another complaint I have, the bike came with almost no instructions and tells you to check you tube for details. One more thing to take into consideration is that I am about 200lb and it's seems just about at the weight limit for this bike. Still, it rides great for me. All in all for the price this bike serves its purpose and has been a helpful and fun asset to my everyday wanderings. I can't wait to take it to the beach and Cyclavia!

    Love my bike!

    Posted by Henry on Jul 31st 2016

    Never had a folding bike, but this bike rocks! Materials are high quality and the full suspension make the ride very smooth around our nation's capital. Definitely recommend this bike to all those that are looking for an alternative commuting option. The bike will for itself in about three months!

    It fits in my car!

    Posted by Lance W on Jul 31st 2016

    I have a Smart car, which is as small as they come. And I was so glad to discover that the 8FS fits in the very tight space behind the seats. I emailed DOWNTUBE/Yan a photo to prove it, and it's now included in the photos here. See above. I am very happy with the bike. Other than the seat--which I immediately replaced--the bike is everything I wanted.

    Great bike!

    Posted by Michael Marble on Jul 31st 2016

    My bike arrived in less than a week. I've never owned a folding bike, but it was pretty simple to figure out the folding and unfolding after following the links here to the videos online. I brought it to the bike shop for the initial set up, and I was good to go. Due to the full suspension, the ride was very smooth on my test drive; and the gear shifting was smooth, too. Seat and handlebars adjust easily. It seems to be a fine bike so far. It's sturdy, and it looks cool, too. I look forward to using it a lot as soon as winter's over here in Minnesota (so, yeah, around June).

    great bikes, amazing customer service

    Posted by Sandra Evans on Jul 31st 2016

    We ordered two bikes, received them in less than a week, and they are beautiful. I had some questions regarding one of the bikes, so I left a voice message for Yan. I also sent an email, so I could send photos of the issue in question. It was late afternoon on a Friday (even later for Yan, since he's on the east coast), so I figured I'd hear back sometime the following week. He called back the same night! He answered all my questions, gave me much needed advice (I'm quite new to biking), and was great to talk with. Exceptional customer service.

    We are so happy with our bikes. They fit exactly what we wanted. Highly recommended.
