Addmotor MOTAN M140 Stepthrough Folding Fat Electric Bike



The MOTAN M-140 Folding Electric Bike is the step-through women's version of the Addmotor M-150 ebike and is designed to be easier for women, smaller riders, elderly people, or those with balance issues to mount.

It is designed to fit adults with a height of 5'2"-6'4" close to 300 lbs. 

The luxurious 4-inch fat tires provide extra cushioning and balance while providing better traction, making it especially a great option for sand or snow.

Powered by a 500W rear-drive brushless motor and a 48V lithium-ion battery, it goes up to 23mph with a whopping 40-55 miles per charge, and the pedals are fully functional with battery powered off. 

Features a night mode LCD display screen for excellent night visibility that shows mileage and speed. Includes a USB charging port so you can charge your phone while you ride. 

This sweet bike has mechanical front and rear disc-brake design and a Shimano 7 Speeds TX55 Gears Professional Transmission System to help you move fast and stop easily.

This Addmotor model has recently been upgraded to include a rear cargo rack and iron fenders. Ebike photos do not show the rack for fenders, but it is included with both colors. 

Collapsible top-tube, frame and pedals make it portable and easy to store in your car, boat, airplane, home, or anywhere else you can imagine needing a small, powerful bike that folds away in only 10 seconds.

The long-lasting Samsung Battery ensures that you will have plenty of fun riding it every day. We promise you will love your Addmotor Motan M-140 electric bike.
