The drivetrain is a mechanical system made up of several parts. Its purpose is to transfer power from the engine to the wheels of an e-bike, making the e-bike move forward. The drivetrain usually includes these components:
  • Cassette
  • Derailleur
  • Shift Lever
  • Crankset
  • Chain
Typically, the drivetrain is most prone to getting dirty. These components are closest to the wheels, so they have to endure wear and tear from various terrains. Therefore, regular maintenance can effectively prevent frequent drivetrain replacements, reducing unnecessary expenses.


1. Cassette: SHIMANO 8-speed


2. Derailleur: SHIMANO


3. Shift lever: SHIMANO


4. Crankset: 1/2"*3/32"x46Tx170mm with double cover


5. Chain: KMC 1/2*3/32″*120L

The Shimano cassette on the eXplorer includes eight gears. They are attached to the rear hub, through the cassette body.

Maintenance Tips

A compressed air cleaning gun can remove dust from the cassette, chain, and crankset for routine riding maintenance.
If you ride on gravel, muddy, and weedy trails for a long period of time, you will need to use a water hose to clean your drivetrain on a regular basis to avoid dirt and grime from damaging cogs and chains. We advise not to use a pressure washer for this type of task, as it could damage the bearings in the bottom bracket (for the crankset) and the rear hub. A regular water hose will fork fine.
After cleaning and drying these parts with a rag, chain included, applying a thin film of specific bike-chain oil on the inside of the chain (and wiping off the excess) will effectively protect your drivetrain and reduce wear and tear.
