Getting started: What do I need to pay attention to before buying an e-bike?

The amount of torque
    In terms of cycling environments, electric mountain bikes require motors with higher torque output, often using torque sensors to accurately detect pedal torque to understand rider intentions, making it easier to ascend steep and complex off-road climbs even at low cadences.
    Therefore, the torque output of electric mountain bike motors is usually between 60Nm and 85Nm. With a 500W power rating and a torque output of up to 120Nm, the M600 drive system maintains strong power in mountain riding.
    The electric power system designed for highway pays more attention to the smooth performance of the pedaling rhythm and the smooth progressive performance of the motor assistance, because the tuning of the power will be different, and the smooth pedaling under high-speed cruising does not require excessive power intervention, so the motor torque output is generally not too large. The Bafang M820 mid-mounted electric power system, specially developed for road cars, weighs only 2.3 kg, but can output 250W rated power and a maximum output torque of 75N.m. The Bafang H700 hub motor has 32Nm of torque, which can easily ensure strong performance in daily commuting and leisure use.
    If you want to take a walk-and-go trip on an electric power, the higher the total weight of the vehicle with full equipment, the more difficult it is to maintain continuous power delivery when climbing, and therefore the greater the need for torque.
    In addition, it is not that the more torque is better, too much torque output will reduce the effort of human pedaling, and on bumpy roads it will become more difficult to control, when the motor has been at 300% auxiliary power output, too easy riding will inevitably make people bored.

Gauge selection
    A high-definition color display can clearly display motor-related data, including battery remaining percentage of battery, riding distance, altitude, sport mode and current speed and other rich information, which can meet our daily outing leisure cycling. Of course, in different riding scenarios, our requirements for instruments are naturally different. Mountain biking has complex road conditions, and has slowly shifted from large-screen meters to integrated meters.
    Road bikes pay great attention to factors such as wind resistance and weight, and just like the enduring 530 yard meters on the market, volume and weight are always important factors for road bikes to consider.
    In the new generation of electric commuter vehicles under the trend of intelligent electronics, simple and easy-to-use embedded instruments are becoming the trend trend of mid-to-high-end vehicles, embedded in the upper tube instrument buttons only through the light color to indicate battery level, gear and other information, greatly simplifying the display information of electric power assistance, while the simple appearance and comfortable linear auxiliary power refresh the riding experience of urban commuting outings.

Battery capacity
    The largest proportion of the weight of electric bicycles is undoubtedly the battery. The battery has experienced a rough and barbaric external plug-in and slowly transitioned to a restrained and simple embedded direction. The battery embedded in the downtube is a common installation method for electric power, and the further solution will completely hide the battery in the frame, which is stable and cleaner in appearance, and can reduce the weight of the whole vehicle.
    Long-distance crossing models demand longer battery life, full suspension mountain bikes are more concerned about strong power output, which requires large-capacity battery support, but larger and heavier batteries will take up more space and require higher frame strength, so the weight of these types of electric models is often not too light. 750Wh, 900Wh batteries are becoming a new benchmark for this type of model.
    Highway, commuting, urban and other models pursue the balance of performance and lightweight, will not blindly increase the battery, 400Wh-500Wh is a common battery capacity, the endurance can usually reach about 70-90 kilometers.
    You know the basics of motor, performance, battery capacity, instrumentation, etc., and you can choose the right electric bike according to your daily riding needs! What else would you like to know about electric assistance?
