25-40 Mile Range

Our high quality Samsung cell batteries will get you between 25-40 real-world miles per charge. This depends on rider weight, terrain, and riding style.

28 MPH

This thing's a beast. You'll reach a top speed of 28 mph using throttle only. If you pedal with the motor you'll go faster.

2 Year Warranty

This covers both bike and battery from any manufacturing defects. If you have a problem bring your Murf by the shop or give us a call and we'll have you up and running in no time.


We redesigned the frame of our Fat Murf to accommodate a high torque mid-drive motor. With the motor connected directly to the cranks you'll notice an increase in power as soon as you push on the pedals. We've set the top speed at 28mph (the legal limit for CA). Climb steeper hills, get up to speed faster, and have more fun on this beast of a Murf.


After three years of riding our Fat Murfs we realized that we rarely changed gears...so we ditched the seven speed and went with one. The increased torque of the mid-drive motor is matched perfectly to the new gearing so you'll still be able to climb hills like Lance without breaking a sweat.


The new full color display provides you with more information on a brighter and easier to read screen. We've also included a USB port so you can charge your phone...if you're in to that sort of thing.
