The chain
It is subjected to even greater stress when e-biking. A dry chain loses efficiency, causes increased wear, jumps and is more likely to break. Caution: With certain Bosch motors, the crank can only be turned forwards. So: Turn the bike upside down or hang it on the assembly stand.
How often to lubricate?
Principle: Clean the chain first, then oil it! After every ride in the rain and after washing. Otherwise every four weeks at the latest. Rub a slightly dirty chain with a cloth, then oil it. After a few minutes or the next day, rub off any excess.
Check!
The chain becomes longer and longer during operation. If a certain length is exceeded, the chainring and sprocket will be severely worn. A Gauge reveals excessive elongation. If the chain jumps, look for stiff links and make this point flexible by bending it sideways back and forth.
The circuit
The cleaner, the better the gears slip. Press the rollers with a soft object (Tyre lever) from dirt. Then treat their bearings and the joints of the derailleur cage - including the derailleur, if still present - sparingly with silicone oil. Do not use grease or resinous oils, as these will only attract dirt.
How often to lubricate?
After riding in the rain and after washing. Wipe dry with a soft cloth. When treating with spray, take care not to spray anything onto the brake disc. Interval in dry conditions: six to eight weeks, clean the brake discs every week depending on use.
Check!
If the derailleur hanger is slightly bent, the gears will jam. At axle height, check from behind whether the derailleur cage is exactly perpendicular (parallel) to the sprockets.
