    The Alpha Murf is the ultra-fast electric bike (28 MPH)


    30-50 Mile Range *

    The Alpha Murf features a 20 Amp Hour battery. That means you'll get roughly 30-50 miles per charge depending on your riding style. If you pedal with the bike you'll get closer to the high end of the range.

    * Rider weight and terrain are a factor.


    52 Volt Battery

    A 52V battery is able to deliver the same amount of power using less current, this means you'll get awesome power from your fast electric bicycle while generating less heat in the motor and controller. A higher voltage e-bike also allows you to get more range out of your electric fat bike before you notice any decrease in power.


    28 MPH *

    The Alpha is Murf's fastest electric bike. You'll reach speeds of 28 MPH (legal limit) with ease. Pedal with the bike and faster speeds are available.

    * Depending on rider weight.


    2 Year Warranty

    This covers both bike and battery from any manufacturing defects. If you have a problem schedule a service appointment on our website or reach out to us via phone or email and we'll have you back up and running in no time.


    One of the main questions we get here at Murf is "what's the difference between the Alpha and the Fat Murf"? The Alpha Murf has a higher top speed (28MPH vs 25MPH). The Alpha Murf is a single speed bike while the Fat Murf is a seven speed (we're talking gears and not pedal assist levels here). The Alpha Murf features a super bright, off road style headlight along with an integrated rear/brake light. The Alpha Murf also features an upgraded color display. Over all the Alpha is our fastest e-bike available, more powerful bike, with a much brighter headlight, an upgraded screen, and a built in rear rack.
