Frequently Asked Questions about the Gazelle Ultimate C8 HMB

1. How Does An Electric Bike Work?

An electric system consists of several main components:

• The Battery: integrated into the luggage carrier or integrated with the frame (depending on the model)
• The Motor: built into the frame at the bottom bracket
• The Display: fitted on the handlebar
• Sensors: Every electric system has a speed sensor, which measures how fast the bike moves. In addition, pedaling input is determined by a rotation sensor or a pedal force sensor, depending on the model. The Impulse system has a fourth sensor, namely the shift sensor. This sensor cuts out assistance for a quarter of a second while you are shifting, enabling you to pedal while shifting.

Together the sensors determine the amount of assistance provided by the motor based on your assistance level setting and the pedal force you are applying. You set the assistance level yourself using the handlebar grip control.

3. Which Factors Affect Range?

The range is dependent on various factors. Thus, the speed at which you ride the bike will have a major impact. See below for the average range at various speeds. In addition to speed, other external factors affect the range. The range advertised in our brochures and manuals is based on averages. Thus, it is assumed that the average rider weighs 70 kg or 155 lbs, cycles on relatively flat terrain, and shifts gears actively. Below you will find the leading factors that affect the range:

• Weight: The total weight of the bike, the rider, and the load will affect the range.
• Gear-shifting behavior: Actively shifting gears increases the range. Like a car, you should start in the lowest gear when setting off from a standstill. Never start in the highest gear; this will adversely affect your range.
• Type of sensor: eBikes are fitted with a pedal force sensor or a rotation sensor. A pedal force sensor amplifies your own effort, whereas a rotation sensor only assists while pedaling. In other words, the rider will always get maximum assistance with a rotation sensor, which results in less range.
• Type of road surface: The surface over which you are cycling substantially affects your range. Thus, cycling along an unpaved road surface will reduce your range.
• The weather: Cycling with a tailwind or into a headwind will increase or reduce your range. The temperature will also affect it. Thus, at extremely low temperatures (< 32 degrees Fahrenheit), the battery can store less energy, which reduces the distance you can ride. 
• Hilly terrain: You can cycle further on flat terrain than on hills. The magnitude of the impact will also depend on the type of electric system. Thus, a mid-mounted motor is better suited to hills due to the motor’s thermal stability.
• Tire pressure: Under Inflated tires increase rolling resistance, which draws more power from the motor.

Considering that you will probably experience a number of the abovementioned factors, here are a few examples of the magnitude of their impact:

• For example, a rider weighing 210 lbs (95 kg) cycling on the good pavement in hilly terrain may find the battery range reduced by up to 20% compared to what is shown for the average range.
• If you are cycling into a strong headwind, it can make a difference of up to approximately 40%.
• If you are cycling along an unpaved road, your range will be reduced by approximately 30% compared to cycling on the pavement.
