This folding electric bike features a single speed drivetrain paired with the Copenhagen Wheel from Superpedestrian, a 350W hub motor with integrated battery. The system which is completely contained in the rear hub provides pedal assistance, allowing you to ride farther and longer without tiring. It’s perfect for long commutes or hilly areas and can bring the joy and simplicity of single speed riding to anyone.

The hub is controlled with a iOS or Android smart phone app* so there are no wires, throttles, or external batteries. Choose your level of assistance with Turbo, Standard, or Eco mode and the hub does the rest, providing extra torque when rider input is detected. And at the end of your ride this e-bike folds in seconds for storage or transport.

*iOS or Android smartphone is required to operate Copenhagen Wheel. See specifications below for OS version.
**Bike and Copenhagen Wheel ship separately and installation is required upon delivery (see details below)

Why a Folding E-Bike?

The biggest challenges with e-bike ownership are secure storage and transportation. A folding e-bike solves them both. It’s too risky to leave your e-bike locked up on the street but having the ability to fold it into a compact package in seconds allows you to store it easily in the home or office, and travel with it anywhere. It can fit in the car trunk, on the bus or train, and is perfect for your next trip.


Why Montague?

We set out to create the highest performance folding bikes in the word. All Montague bikes use full-size wheels, standard components, and a folding design that doesn’t break any of the frame’s tubing. Our focus has always been on perfecting ride quality, handling, and comfort.

“Once I started riding the bike, I quickly understood that the Boston had more going for it than just storage economics. It’s fun, too. On bike paths, around town, and up and down hills, it proved to be a snappy and responsive ride. It’s a bike I’d ride, even if I wasn’t short on space.

Breaking down the bike takes no more than 30 seconds, and in its compact state, it’s easy to carry or stow in the back of a car (in addition to closet).”

Bicycling Magazine

“Though it looks like a simple bike wheel, the Copenhagen packs impressive technology inside. An integrated motor powered by a battery provides the giddyup, a wireless sensor connects to smartphones for data crunching . .  . and regenerative brakes add to the efficiency.

Turns out reinventing the wheel was worth it.”

TIME Magazine

Wheel Installation

Your bicycle and Copenhagen Wheel will arrive separately requiring you to install the wheel on your bike before riding. In addition to the Copenhagen Wheel, your bike will also arrive with a standard rear wheel so you will always have the option of switching to a non-electric version.

The video below shows how to properly install the Copenhagen Wheel on your bike. If you are not comfortable doing this yourself, please have the work done by a professional bike mechanic.
