This 16 inch mini folding bike is our smallest and lightest bike making it perfect for travel. It is super compact to fit in the trunk of a vehicle or into a standard sized suitcase. You will fall in love with the 11sp Shimano internal hub which is paired with a Gates CDX belt drive system. The gear range on the 11sp has a whopping 408% gear range which is perfect for any terrain. The internal hub/belt system is new to the bicycle industry. The mini 11 also adds light action trigger shifters, 2.2" wide tires for comfort, and crank/BB system with external bearings for high efficiency and stiffness. 

It is super lightweight because everything on the bike is aluminum and the miniB (Belt) employs a Gates Carbon belt and cogs. You will really fall in love with the idea of having frames made from lightweight aluminum and an integrated headset, and bag interface on the headtube ( we have custom bags on the way ). We are now including free accessories on all miniB's: a rack, kickstand, and rear fender. The rack is perfect to carry loads, and the rear fender will keep you clean even when the terrain gets dirty. A font fender is not necessary since the frame will act as a front fender.

The Tekro V brakes in combination with the machined-sidewall rims are quality and make the bike stop super fast. 

Rear derailleurs are known to be the weakest link on a bicycle, removing it makes the entire system stronger and more vibrant. Additionally, by using a belt system it is grease-free, hence there can never be a black streak on your leg, and you need not worry about messing up any place you leave your bike. Shifting will be butter smooth as is standard with Shimano's high end internal hub systems. Overall, this mini bike is really small, light and the drive train is nearly maintenance-free. This is the ideal bike for a boaters, RV'rs, rail and for airport travel.

    Great Bike and amazing price

    Posted by Donald on Jun 10th 2017

    I ordered two mini11's. They came very well packaged, in perfect condition, and were easy to assemble. Excellent recommendations and service from Yan.

    Only one trivial recommendation: manual reads "calibrate with shifter in 4th gear" but for 11 speed, it should be in 6th gear. Also, manual could use more photos.

    But they are beautiful bikes, well made, the ALFINE gearing us vastly superior to a derailleur for a folding bike, and so is the Gates belt drive. Totally clean, no oily, dirty or greasy chain, no derailleur to get bent or broken.

    These bikes will be stored in the engine room on our boat. The small size, foldable pedals, belt drive and Alfine gears make it clean and safe to store with minimal maintenance.

    Alfons is also much easier to use for less-technical people ( wife) than derailleur gearing.

    I was going to order a similarly equipped bike from a competitor. It would have been twice the price. Fortunately, they were out of stock, so we ended up getting the Downtube mini11's, at essentially two for the price of one, and am totally satisfied.

    I ride two Cervelos, two Montagues and a host of Treks for other purposes. This is PERFECT for the boat, car or plane.
