The King 750 is the most recent fat e-bike from DYU. It’s an aluminum 26er mounting 4″ tires, a proper fat bike able to tackle the sandiest or muddiest of tracks.

Boosting a powerful and recently redesigned 750 W motor, the King 750 can reach a top speed of 28MPH (or 45 km/h) on flat terrain, definitely not bad for a fat bike while hills up to a 15% gradient is easily challenged.

The 20A LG battery Makes you able to ride for 50 miles or 90 km on a single charge and gets fully recharged in about 6/7 hours. Last but not least, the price: at less than 1800$ (1700€) the King 750 by DYU is convenient and very competitive.

Riding Experience

We were impressed by the comfort and rideability of the King 750, for this price range it hits all the sweet spots for fat-bike lovers.

This adventure rig by DYU features a smooth multiple shock absorption system, with suspension forks and suspension seat tubes, making the ride silky on any surface, from snow to hard rocks, from sand to mud.

It is equipped with a torque sensor for a more responsive and intuitive ride, making climbing much easier.

The well-being of your wrists is guaranteed by ergonomic and padded grips for a quite comfortable ride also when vibrations hit the peak.

The Tourney Drivetrain is a staple of reliability for this kind of price range, tested and proofed on gazillions of bikes, it’s a real classic.

The stopping power of the hydraulic disc brakes has proven itself on steep sandy descents and didn’t fail the test.

About the electric part, the DYU King 750 has a 20Ah long-lasting battery coming out from the LG factory. It guarantees to be able to power the 750w high-power motor at an average speed of 22mph for 50 miles on a single charge but can reach as far as 80 miles if the conditions are optimal.

Overall, a great riding experience for such a convenient price tag.

The DYU King 750 design makes it quite a versatile electric bike. The relatively long wheelbase makes it stable under heavy loads, making it a good e-bike choice for big guys, but also for electric bike touring.

The 4″ fat tires, paired with the front suspension and the suspension seat post, make this bike as comfy as a bike can possibly be on mixed or rough surfaces.

Accessories provided are basic but useful: speed sensor, battery display, and most importantly front and tail lights. The battery is detachable for the most convenient charging experience.

The choice of black color and the aerodynamic tube shapes make it look pretty sleek and cool both in an urban context and in nature.
