Bullshark m500 is loaded with power, gets me up hills without pedaling. Living in a hilly area, its awesome to get around much easier. Great design, hidden battery clicks into the frame. Looks like a regular bike, more discreet than other brands. Better value for money and quality than other brands..

Bullshark m500 is the perfect bike ive been looking for. Hidden battery clicks into the frame seamlessly. And the power is amazing for a bike with such an awesome price. You cant go wrong with this model. I bought it 4 years ago, and still going strong, without a problem.

Fast delivery, was impressed with the service, put my order in, and the next day the bike was already here. And that was during covid lockdowns too. Really enjoy the ride, so easy to use, heaps of power at your fingertips ready to go. Ride to work everyday now to avoid the traffic, gets me there without a sweat. Best feature is the POWER!

This is my 3rd Reef Bike, first bought the Bullshark mountain, then bought a Bullshark m500 and Bullshark f750 for all my family. Cant get enough of these Reef Bullsharks. Our family loves getting out riding down to the beach on the weekends together. Best Australian electric bike brand. Had my bikes for over 6 years without missing a beat.
