Koa (750W Hybrid Cruiser)

The Koa

The Hawaiian meaning of Koa is brave, bold and fearless which is why it's the perfect name for this bike! We were asked to make a bike that looked like a Mountain bike, but rode like a beach cruiser/commuter bike and the Koa is just that. Featuring a 750W Geared Hub motor providing high torque and high capacity along with a 7-speed gear shift system, you can ride up to 45+ miles and barely break a sweat. Cruise in comfort with front wheel suspension, 4" fat tires and an oversized gel seat. Mechanical disc brakes will safely bring you to a stop and the sleek designed frame will have people asking you all about your new bike. The handlebar mounted control screen offers you 5 different levels of pedal assist so that you can dial in the perfect amount of power. You can also use thumb throttle and ride the Koa e-bike like a moped.

Just the right Power

The high quality battery for the Koa comes in at 48 Volts and 14 Amp Hours. What does that mean? Simply put, a higher voltage battery is able to deliver the same amount of power using less current, this means you'll get awesome power from your bike while generating less heat in the motor and controller. A higher voltage also allows you to get more range out of your bike before you notice any decrease in power. Amp hours can be thought of as the amount of gas your battery can hold. A higher amp hour number means you'll get more range per charge. We regularly have customers tell us they're able to ride up to, and even over, 45 miles per charge.

Bang for the Buck

You can find a cheaper electric bike, and you can definitely find a more expensive electric bike, but when it comes to value, you'll have a hard time finding something better than a Black Rock Bike. When you compare design, components, battery specs, reliability and included warranty, a Black Rock electric bike offers the best value for the money. 

The Black Rock Bikes Difference

As a bike tour operator in Maui, Black Rock Bikes has researched and vetted over 100 brands of bikes including E-Bikes. We realized very quickly that high quality, economical electric bikes didn't exist. With all of the knowledge and first hand experience we receive on a daily basis, we knew we could fill the void and decided to manufacture our own line of electric bikes. With overwhelming amounts of ecstatic renters coming back each day after using our Black Rock Bikes, we decided to open up sales to the general public. We attribute our success as a company to our unmatched passion to serve our customers and that shows in the number of people that refer their friends and relatives to us. We honor our 1 year warranty without hesitation and strive to offer the best customer service in the electric bike industry.
