There are two types of hub motor wheels are used for e-bikes. One type is hub bldc motor , the other is brushed hub motor. Because the brushed motor had some disadvantage of high noise, shorter-use life, low efficiency..
These days hub bldc motor wheels are used for electric bikes widely and had replaced brushed hub motor.
Convert a bike to an e-bike, we should choose a hub bldc motor wheel with brushless controller and throttle, brake lever,on/off switches,disk brake,front&rear lights,horn..etc accessories
European like 250w hub bldc motor and North America prefer 750w / 1000w bldc motor. How to purchase a good brushless controller to drive this bldc motor .
Generally 250w bldc motor need to be driven by 6-MOSFET brushless controller, and a 9-MOSFET motor controller dirves a 750w bldc motor,a 12-MOSFET brushless controller dirves a 1000w bldc motor.
Now nearly all types of brushless controller for e-bikes have cruise, alert, reverse, limited speed..etc. function.
If you buy 1 set 48V DIY kit, you had better to choose 48V 12-MOSFET/15-MOSFET brushless controller. Please don’t order 9-MOSFET motor controller to drive your 1000W brushless controller, it’s the heart of e-bike. 1000W bldc motor will bring larger current and high temperature, 9-MOSFET can’t afford.
For the bulk .of motor controller, larger, better. Larger bulk has better cool system.
In past, there was a guy sold regen motor controller, but nearly all sold regen controllers were broken in 30 days. Because when you brake, this regen controller will bring twice current to stop your e-bike, thus larger current would break MOSFET directly.
Now programmable controller is still showed in market. This brushless controller seem has nice face, but its head is small, can’t stuff more MOSFET. Use this brushless controller to drive 750w / 1000w bike system and break this nice face controller is normal. Don’t be arrest by programmable. You will find nothing for actual use when you use.
We have LCD cruise controller, more MOSFET, don’t worry your motor controller will be broken.
