With COVID crisis spread in worldwide,considering of the public safe distance,electric bike has become one of the most popular transportation method,it is environmental as well.People are thinking of converting their bicycle to electrify an electric bike,but facing many things to build an e-bike.We would to guide you choosing the right motor from the following factors,quick to select your motor.
Motor Location(front wheel,rear wheel,middle place-bottom bracket)
Motors can typically be fixed in three different places on an bike: 1. Front wheel, 2. Rear wheel, or 3. Bottom bracket (Mid-drive motor). The front and rear wheel motors are known as hub motors because they take over the hub of the wheel. The primary advantage of these types of motors (such as TDCM or Aikema motors),they are relatively simple and straightforward to do a conversion once you get a wheel built around the motor - just replace your wheel, connect the battery,and you're off! The mid-drive motors (such as Bafang maxdrive,Bosch Active line,Tongsheng TSDZ-2) replace your crank and chain ring through your bottom bracket. The advantages of these motors are they end up taking advantage of your gears and keep the weight distribution low and near the center of your bike.
Voltage and Power Matters
It's easy to get lost in these numbers since everyone will try to sell you on "more performance." But you really need to assess your riding to figure out what you need. First of all, neither of these numbers will necessarily get you faster speed. Top speed is generally capped at 20 or 28 mph depending on the system and this is a government regulation. Lower power motors are perfectly suitable for relatively flat, around town riding and you'll still be able to hit 20 mph or more! More power is best if you're towing a load or are a larger rider. It will also accelerate a little faster and will go faster uphill. A higher voltage motor will allow you to use fewer cells in your battery because the current draw will be less for the same power. As such, it won't run as hot either, which will minimize potential overheating problems. If you don't need to sustain maximum power though, a lower voltage (such as 36V 500W Aikema 128 SX) system will work just fine.
Price always the concerns
Of course one of the biggest determining factors in many people's decision to convert to an e-bike is price. Front hub motors like our Aikema kit are generally the least expensive and are great for leisurely rides around the city. They're the easiest to work with since you don't have to deal with the gears and drivetrain at all when doing the conversion.
Rear hub motors like TDCM kit,MAC kit would be the next step up. These have a freewheel attachment for the rear cogs and provide 500W of power to tackle the odd hill.
The mid-drive motor system TSDZ-2/3 is our premium motors but provide access to gears giving more torque assist.With double side detection torque sensor is the highlight of this central motor kit.
