It’s the energy capacity of battery. Wh=Ah x V. For example a 48V, 8.8Ah battery gives you 48V 8.8Ah = 422.4Wh energy which ideally means you can draw 422W power for 1 hour. The equivalent battery in 36V standard will be about 11.7Ah

It’s the current capacity of the battery. The maximum current the battery can be discharged at continuously for 1 hour. For example; you can draw 10A continuously from a 10Ah battery for 1 hour or 5A for 2 hours.  This is a parameter that gives you a range. However, the energy density of a battery [...]

Power equals Voltage by Current: The higher the voltage, lower current is necessary to get the same amount of power (P=VI).  The voltage should be managed by compromising safety and current rating of component. This is a parameter which is set based on electrical characteristics of the motor/controller and wiring.  Voltage has no mechanical effect [...]

The amount in Watts shows the power (P) of motor. The power is important for riding faster both on flat or slope. There is a rated power definition for electric motor, which is the nominal power that the motor is designed to work to deliver efficiency and long life. Usually maximum or peak power is [...]

Here is an estimated cost of brand new battery packs or refurbishing the battery with new LG, SAMSUNG or Panasonic cells and BMS: Voltage & Capacity cells BMS Estimated Price in C$ 48V 17.5Ah 18650 LG or Panasonic 30A rated 895.00 48V 13Ah 18650 LG or Panasonic 30A rated 695.00 48V 10.4Ah 18650 LG [...]

We will have various solutions for older ebikes battery replacement; either by installation of cased battery packs or refurbishing the existing battery case. You need to send us the existing battery and charger so that we test and refurbish with a similar or better capacity and performance using 18650 Li-Ion Cells from LG or Panasonic. [...]

Repairs will be charged on an hourly rate of 75C$. We will let you know the rough estimate in advance. We will also keep open communication throughout the entire process to ensure the services and replacements kept in budget.

Basically all generic BLDC motor controllers should match one another; however there is no protocol for wiring and connections. One should figure out the wiring pin by pin if a wiring diagram is not available. There is always a way to put the broken motor or controller back to work; we should work out the [...]

Yes. All hub motor kits have disk brake standard 6 bolt pattern mounting flange.

No, Motors are considered maintenance free unless something happens.
