Our Flagship Folding Bike

The 11H built with exceptional quality is our 20 inch wheel flagship model. Everything about the 11H is top-tier, from the overall design to the smallest details.

The 11H uses a Shimano Alfine 11sp hub with Gates CDX belt which provides a super-smooth and efficient riding experience. With a 100,000 mile wear rating, replacing that belt is something that you won't ever have to worry about. The bottom bracket has external bearings, and is directly connected to the cranks for hyper-efficiency.

Shifting gears is easy and intuitive with the single, handlebar mounted Shimano Alfine trigger shifter. Aside from the ease of shifting gears and not having to worry about fatiguing the metal chain, this 11-speed gear hub takes maintenance off your to-do list as the internal hub is completely sealed from damaging dirt and grime. Add to that smooth shifting similar to that of standard dérailleur drive train and you have the best of both worlds.
To make the 11H even more comfortable, the 2018 model has a disc front hub, 60T front CDX chain ring and a 22T cog. As the 11H has no rear cluster or chain, you won't have to worry about improper shifting or cleaning the drive train. Get on your 11H, enjoy your ride and don't worry about a thing.

We've added plenty of features that'll make you love your 11H even more: a super-light aluminum frame, suspension fork, quality hubs (disc front), lightweight fenders, and a durable rack and kickstand come pre-installed on the 11H to make your life much easier.

The mini bar ends and high-rise handlebars give you more, by allowing a custom fit without interfering with the fold.

As for the braking system, we settled for nothing less than a top-tier Tektro V-brakes setup. Combined with rough machined-sidewall rims, the 11H is able to stop immediately, as the V-brakes engage the textured surface on the rims. A disc front hub means upgrading is quick and easy.

For commuters, we added an interface for the headtube bag system, a frame quick release, folding aluminum pedals, and an adjustable-height stem. All of those features make the 11H commuter-ready right out of the box.

Designed to excel, and built with high end parts, the 11H provides a flawless riding experience and mobility that'll redefine your perception of the capabilities of a folding bicycle. If you're looking for a top-tier folding bike for your travels or daily commute, the 11H is guaranteed to exceed your expectations.

    Downtube 11-H

    Posted by John on Aug 14th 2018

    The 11-H is all I expected it to be, a great value and a smooth riding bike. I haven't seen a bike with a Shimano Alpine and a belt drive for less than $3,000 until I wandered across Downtube. After a week of ownership I have absolutely no buyers remorse.

    Downtube 11H Rocks!

    Posted by Laurie on Nov 27th 2017

    We purchased an 11H to join the 8H on our catamaran sailboat on our worldwide tour. It is everything that we wanted, easy to fold and unfold, versatile, good tracking on the uneven streets and dirt roads of Mexico, rust free belt drive and maintenance free internal hub. The gears changes are smooth and the panniers can expand to hold groceries or hardware. The carrying bags make it easy to transport the files bikes into our boat or dinghy. Overall, a great purchase and one that is ideal in the confined space of a boat. Thanks, Yan!.
