About The Bafang Ultra Mid Drive Motor
The new Bafang Ultra mid-drive motor is one of the most powerful mid drive motors on the market. With 750 watts of nominal power and up to 1500 watts of peak power, as well as 160 Newton meters of torque, this is an electric bike that can climb the steepest hills with ease. Like the Bafang Max drive system, the new Bafang Ultra motors constantly sample relevant information at a frequency of up to 80k Hz via a torque sensor and two speed sensors which are all highly sensitive. The resulting data on crank torque, vehicle speed and the speed of rotation of the pedals is made available to the controller, ensuring precise control of the vehicle while achieving the highest possible efficiency. The Ultra Max Drive System puts the rider in complete control. In spite of a generous power output and a maximum torque of more than 160 N.m, the motor operates in virtual silence.

What size should I get? We recommend customers between 5'8" and 5'11" order the medium frame bike and will find it to be a comfortable ride with optimal stand-over height as long as their inseam on their pants is greater than 28" in length. The large frame bike is best for customers between 5'11" and 6'3".
What is the frame size and stand-over height? The large bike has a bottom bracket to top of seat post length of 19" with a stand-over height of 31". The medium frame has a 18" bottom bracket to top of seat post length with a stand-over height of 29.5".
What is covered under warranty? Our warranty covers the frame, motor, battery, controller and display for one year. The other parts of the bike are subject to wear and tear and are not covered under warranty, but you can expect to receive full support from our customer service team to assist with any and all repairs, including access to replacement parts for the life of the bike.
How long does the battery last? Generally the batteries are rated for 900 charge cycles, which should be 3-5 years for most users. The range per charge can be anywhere from 20-75 miles depending on how hard you pedal, how steep the hills are and how fast you're going. Check out our battery range video for more info.
Is the bike waterproof? While our bikes aren't fully waterproof and should not be submerged in water, generally speaking they are very water resistant and can be hosed down and washed like any other bike. The battery, motor and display are fully sealed and can resist rain, snow and being hosed down after a ride. Like any bike, you'll need to make sure to keep your chain lubed and well cared for to ensure optimal performance.
