The Downtube 11H is our newest flagship folding bike. The 11H uses Shimano Alfine 11sp hub with Gates CDX belt. The Gates Carbon Drive belt is rust-proof and won’t stretch or slip as you change gears. It uses a proven belt technology more commonly found in motorcycles. The rounded carbon fiber teeth on the new belt is easier to maintain, more reliable, smoother running resulting in a more comfortable, relaxing riding experience.

The 11H multi-speed Shimano Alfine internal gear hub uses a single, handlebar mounted shifter, that’s so intuitive especially when compared to the dual handed, gear shifters that used pulleys to adjust externally exposed gear cassettes and chain-rings.

The “old days” of remembering which combination of front and rear, left and right derailleur gear combinations to use to avoid stretching and fatiguing the metal chain are over. The virtually maintenance-free Shimano Alfine 11-speed gear internal hub is completely sealed from damaging dirt and grime.

The 11H’s solid legacy of bike excellence has been greatly enhanced with additional design upgrades. If you are a boater, RVer and commuter, you will simply adore this model. Nowhere will you find a better bike with Gates Carbon Drive belt comparable to the affordable 11H with Shimano Alfine 11-speedhub!

The 2017's have a disc front hub, 60T front CDX chainring & 22T cog, and no suspension option. What does all of that mean in layman terms? Well, you will have a bike that allows for a comfortable ride. The 8H, 11H have no rear derailleur or external shifter. It has no cogs or gears as well as no chain. That means you don’t have to be concerned about improper shifting or cleaning the drive train. So much work has gone into making this bike of better quality than it was before.

Not that the previous one wasn’t great, but we wanted to make sure that you had more than our expected. The bike is enclosed in a completely sealed and maintenance-free setting. The 11H is very comfy and that is all due to the 20 inch wheels and the suspension fork. If you are a boater, RVer and commuter, you will simply adore this model.

Nowhere will you find a bike with a Gates CDX carbon drive belt paired to the Shimano Alfine  11sp hub!

This bike gives you the sound of a new evolution! It also gives you clean and quiet riding without the chain, lubrication, stretch or maintenance.

So that you could enjoy the ride, we included some excellent features that included the aluminum frame equipped with lightweight fenders. We also added a durable rack and kickstand. Of course, how could we leave out the high quality levers and Tecktro V brakes? We even matched up the levers and brakes with aluminum machined-sidewall rims, which make the bike able to stop on a dime, immediately engaging the textured surface.

If you use your bike to commute, we thought about you too. We added a water bottle braze-on, but the cage is not included. And we also added an interface for the headtube bag. We went further with our upgrades by adding the frame quick release, folding pedals and stem.

We decided to integrate the headset into the head tube. Additional mini-bar ends and high-rise handlebars give the rider more edge by customizing the fit without having to interfere with the fold.
