Folding Adventure Bike

Built for Exploring

Folding adventure bike side green

Flatbike’s own successor to the popular CHANGE 811 rugged hybrid, this folding bike is built on the same ISO 4210-certified rugged folding CHANGE frame with solid carbon fork, but with upgraded specs for ease of use and comfort.These include:

An 11-speed or 22-speed drivetrain with huge gear range: 1×11: From 3.6 (wheel revolutions per pedal revolution) on flats to 0.77 for steep hills–all with just one shifter.2×11: From 4.2 on flats to 0.7 on uphills.

High-performance Shimano 700c 700c wheels, with 38mm Intezzo tires with anti-flat strip and reflective sidewall.

Venzo Venture split seat for comfort, with Ergo GP1 ergonomic grips.

MTB pop-off pedals included by default, unless you want pop-off SPD or pop-off flat pedals

Put it all together, and you’ve got a rugged 27 lb aluminum all-terrain adventure bike that’s ready for paved roads, potholed roads, gravel singletrack, dirt trails, or anywhere else your travels take you. And then … it folds in half in under a minute to 30 inches by 37 inches, fitting easily in your car trunk, RV, or long-haul truck cab to be ready for your next adventure. Now that’s freedom to explore!

A CHANGE Bike...

Fits in tight spaces

Thanks to an amazing patented latch, a CHANGE bike rides like a performance bike then folds down to 30” by 37” in under a minute. Take it in the elevator easily and add bike commuting or adventure biking to your lifestyle, whether you live in a small apartment or even on a boat.

Is more secure

CHANGE bikes can easily come inside, spend the night in your condo or relax securely post-ride in your car trunk, while all your fellow riders are concerned about their exposed bikes in the parking lot. That’s peace of mind.

Makes spontaneous biking easier

A CHANGE bike doesn’t need a big rig or even a rack to go places. Any car trunk or truck cab will do. Your bike rides inside, and you’ll get better gas mileage too. Have bike, will explore. Carpe diem!

Is made for adventure

Look closely at this latch. Teeth on the frame itself hold the frame together. That’s why the CHANGE frame is the only folding bike to pass ISO-4210 certification, three sets of fatigue tests up to 100,000 repetitions. So go wild. Enjoy portable adventure.
