Throughout the years, ZOOZ has maintained steadfast and scrupulous dedication to improvement and refinement to our core platform -- the UU. Through this quest for perfection and balance, our growing model line-up benefits from new components and other breakthroughs.
The new Ultra Urban represents a large step forward for the UU model, but also for ZOOZ.
The 2024 Ultra Urban features the all new THRILLMATIC motor. This all new, gear-style motor is rated at 750W but peaks at 1800W for periods as long as 6 minutes making the UU the most powerful and the most thrilling Class 2 e-bike experience. For closed course riding, the 2024 UU is able to reach speeds of 34MPH.
The 2024 Ultra Urban also now features our new battery platform, but in a new size of 20Ah (1040Wh) for a real-world range of 25-35 miles when using ONLY THE THROTTLE! While other brands like to over inflate their range claims based on unachievably ideal scenarios, our figures are based our actual testing (and we like to ride the bike at its limit).
Last major change for the UU is that we now have brought he ZOOZ STICKY SWEET tire to the UU in a new size of 24x2.6". All ZOOZ tires are specifically designed and selected for optimal handling performance for each model they are featured on.
Minor updates include the number of bottle cage mounts on the downtube being reduced from four to two. The kickstand has been relocated and improved. The steerer tube has been lengthened for headlight stem clearance and improved handling. Seat foam has been updated and improved.

Heat dissipation and fade resistance are paramount for electric bikes, where hydraulic brakes excel, ensuring dependable performance even during extended downhill rides. Safety takes the forefront with hydraulic disc brakes offering shorter stopping distances and quicker response times, crucial for urban environments. Ultimately, hydraulic disc brakes guarantee an elevated riding experience by combining precision, power, reliability, reduced maintenance, heat management, and enhanced safety. Elevate your electric bike journey with the unmatched benefits of hydraulic disc brakes, where innovation meets performance.

E-bikes have recently become the tool of choice for surfing enthusiasts to get to their favorite surf spot in the minimum amount of time with the maximum amount of accessibility.
But what makes the best ebike for transporting a surfer and their surfboard to the surf spot?! Here are some things to consider:

But what makes the best ebike for transporting a surfer and their surfboard to the surf spot?! Here are some things to consider:
Luckily, ZOOZ Bikes has produced a bike that is perfect for surfers trying to reach the surf spot. The Ultra Flex has all-terrain tires with Kevlar lining, significant power in the motor and brakes, and a tuned suspension to handle the weight of nearly any rider and any size surfboard.
Furthermore, the optional front and rear rack designed for the Ultra Flex are very strong and allow for a large spread to mount the MBB Longboard Rack. Even more importantly, the racks mounted to the frame, which means the rider AND the board benefit from the functionality of the suspension, ensuring you and your bike are confident and secure during transport.
Don't believe us, check out what this surfer has to say about his experience transporting his 9'5" longboard to his favorite spots in Southern California.
Let’s discuss what V x A = W means for power output.
Voltage, measured in volts (V), is essentially the "pressure" that drives the electric current through a circuit. The higher the voltage, the more power the battery can deliver to the motor which will affect both acceleration and top speed.
Another way to think of voltage is in terms of potential energy. Think of a water tower that is full of water. The weight of that water is putting a lot of pressure to flow water through that tube that brings the water to the ground. However, if the water tower was almost empty, the lesser overall weight of the water would mean less water pressure in the tube. Now imagine a waterwheel at the end of that tube… higher water pressure is going to turn that water wheel faster than if the water pressure were low. In electric motor terms, higher voltage will mean more power and speed than lower voltage.
The last thing to note about voltage is that each battery has an operational voltage range. Any battery, both individual cell or a battery pack of multiple cells, will have a voltage range. That is, the maximum a battery can be charged, and minimum charge. Operating outside of this voltage range can damage a battery. Voltage of a battery is classified by it's nominal voltage rating, which is the midpoint between the maximum voltage and the minimum voltage of a battery. For example, a 52v battery will have 58v when fully charged and 46v when fully discharged, 52v being the midpoint. Keep this concept in mind for the end of this blog post.
Now let’s talk about amperage, measured in amperes (A), is the rate at which electric current flows through a conductor. It is a measure of the amount of electric charge passing a point in a circuit per unit of time. The higher the amperage, the more power the battery can deliver to the motor.
Let’s go back to the water tower. Thing of amperage as the width of the tube bringing the water to the ground. If the water tower is full, how fast can you move all that water through the tube? This is the measurement of Amps and it affects how well you deliver the energy stored in the battery to the motor. An ebike will have two Amp figures that are important to note — rated amps and peak amps. Rated amps is how much electrify can flow from the battery, through the controller and into the motor and just keep on going, hypothetically forever. Peak amps is the maximum amount of electrify the system can handle, but only for a short amount of time. Peak amps would be utilized when accelerating, carrying a heavy load or going up a hill. Keep this concept in mind for the end of this blog post.
Wattage, measured in watts (W), is the rate at which energy is transferred or consumed. It is a measure of the rate at which electric power is being used. The wattage of an e-bike battery is determined by the voltage and amperage of the battery. To determine the wattage of your e-bike battery, simply multiply the voltage by the amperage. For example, if your e-bike battery has a voltage of 36V and an amperage of 10A, the wattage of the battery would be 360W.
It is important to note that the wattage of an e-bike battery does not necessarily determine the performance of the e-bike as the wattage is always changing. Remember how a full battery has more voltage than an empty battery? We’ll that means that the first factor of the V x A = W equation will be changing over the duration of your ride. Next, are you cruising on flat land at top speed or are you starting from a stop with a full load at the bottom of a hill? Both conditions will produce a lower or higher number of amps respectively, and will have a massive impact on watts in the V x A = W equation.
Since Volts and Amps are varying throughout the duration of any ride, wattage figures will swing widely which makes the measurement of wattage quite random unless you are trying to determine the maximum power transferred to the wheel, which would logically be done at full charge (maximum Volts) and at peak amperage (maximum Amps).
In the USA, the federal guideline for a class 1, 2 or 3 bike is 750W rated. To get "rated" watts, you use the same V x A = W equation with nominal voltage and rated amps.
This is where ZOOZ stands out against the competition because both volts and amps have been very carefully selected for each of our drivetrains. We have maximized the voltage of each system while still keeping the rated wattage under the legal limit. However, each of our drivetrains are able to reach a much high peak amperage which allows for high wattage output to specifically deliver the best performance and range capacities while still remaining a class 2 bicycle.
]]>These racks are designed to be as sturdy and strong as our bikes and as versatile as possible with the ability to add a wide world third party accessories directly onto the rack such as a basket (we like the Dairyman from Bikase), pannier bag (we like the Chrome Industries Urban Ex 2.0), a skateboard rack (Fairdale makes the dopest one) and more.
Here's a link to see how it seamless installs and integrates into the frame.
