Understand the performance of the electric bike: speed, range, and wheel size

Power & Speed:

E-bikes usually have motors with power outputs ranging from 250 watts to 750 watts, although some can go up to 1500 watts or more for off-road or high-performance use.The maximum speed of an electric bike depends on several factors, including the power of the motor, the weight of the rider, and the terrain. However, as a general guideline, here are the maximum speeds for different power ebikes:

• 250W:15-20 mph (25-32 km/h)
• 350W:20-25 mph (32-40 km/h)
• 500W:25-28 mph (40-45 km/h)
• 750W:28-30 mph (45-48 km/h)
• 1000W:30-35 mph (48-56 km/h)
• 1500W:35-40 mph (56-64 km/h)

Important Notes: The AU regulations dictate that a kit must not exceed the rated power of 250W to be road-legal. Kindly check with your local authorities for further information regarding road use.

Wheel size:

E-bikes come in a variety of wheel sizes, with 26", 27.5", and 29" being the most common for mountain bikes, and 700c or 28" being common for road bikes. Some e-bikes have smaller wheels, such as 20" or 24" for folding bikes or compact models. It is recommended to use a motor wheel that is the same size as the original wheel of your bike if you'd like to transfer your bike to e-bike.

The recommended wheel size for a person's height can vary depending on the type of bike and riding style. Generally, for road and hybrid bikes, the following wheel size recommendations based on rider height can be used as a starting point:

• Under 5'5" (165cm): 26" or 27.5" wheels
• Between 5'5" and 5'11" (165-180cm): 27.5", 700CC, 28'' or 29" wheels
• Over 5'11" (180cm): 29" wheels

However, it's important to keep in mind that the most important factor is how the bike feels and handles for the rider. It's recommended to test ride different wheel sizes to find the best fit for your individual needs and preferences.

Battery capacity & Range:

E-bike batteries typically range from 250 watt-hours to 1000 watt-hours or more, with higher capacity batteries providing longer range. The voltage of the battery varies as well, with most e-bikes using 36V or 48V systems.

Ah (ampere-hour) and Wh (watt-hour) are both units used to measure the capacity of a battery, but they are different. To calculate Wh, you multiply the voltage of the battery by the Ah capacity. For example, a 48V 10Ah battery has a capacity of 480Wh (48V x 10Ah = 480Wh).

The maximum range with pedal assist on an e-bike can vary depending on factors such as the capacity of the battery, the level of pedal assistance used, the terrain, and the weight of the rider. In general, e-bikes with larger batteries and more efficient motors can travel farther on a single charge. But in general, the max range with pedal assist Mode:

• 10AH: 40 km
• 13AH: 50 km
• 15AH: 60 km
