MAINTENANCE AND SERVICING

Belt drive

Your ST7 is equipped with a belt drive (Gates Carbon Belt Drive). The automatic tensioning roller saves you from having to check and retension the belt frequently, making it almost maintenance free.

Please follow the handling instructions be low to help make your belt last longer. Improper handling can damage the belt and may mean that it needs replacing!

• Do not bend or twist the belt.
• Do not turn the belt inside out.
• Do not bunch or coil the belt.
• Do not use as a belt tool.
• Do not use tools or sharp instruments when handling the belt.
• Do not push down on the belt pulley.
• Do not oil the belt.

To extend the lifespan of the belt, we recommend cleaning it with water or a hand brush (e.g. after riding through mud or dirt). Residue left on the belt or belt pulleys can result in increased wear and noise generation (e.g. squeaking or creaking). Use in winter: The belt will not rust but salt crystals may form on the pulley system if salt water is left to dry on it. Even if no dirt is visible, you should wash your bike and belt regularly when using it during winter. Use warm water and a mild detergent or dish soap.

Check your belt drive for damage, deformation or cracks each time you clean it. If you have any doubts, contact your Stromer dealer. If you still notice that the belt system is making noise despite a thorough cleaning, a thin layer of dry silicone spray can be applied to the inside of the belt. This protects it against any further build-up and reduces friction and noise generation.

Gear system

The gears are operated via the Smart. Shift automatic gearshift lever (hereinafter referred to as the "trigger"). The Pinion trigger is an electronic system powered by a BQ1440 battery.

To change gear, press one of the gearshift levers. To shift up a gear, press the front short lever once. To shift down a gear, press the longer rear lever once. You can change several gears in succession by pressing the lever several times. Shifting while pedaling is possible, but not when the load is too high.

You can find more detailed information in the specific user manuals included in the delivery: Trigger: Pinion Smart. Shift user manual; Gearbox: Pinion C-Line user manual; or on the website: pinion.eu/smartshift

You can freely adjust the gearshift lever assignment. Please read the "Trigger setting" chapter for more information.

Belts and pulleys are optimally matched to each other. Do not change the gear ratio. The warranty and guarantee only apply to original components.

Gears are safety-relevant components!
Read the manufacturer's instructions and familiarize yourself with the operation of your S-Pedelec's gears before riding it for the first time. You can find more information at https://pinion.eu.
Leave any gear repairs to your Stromer dealer! Any repair work that is not carried out properly may impact the safety of your S-Pedelec!
If your gears do not shift cleanly, avoid riding any further if possible. Take your ST7 to your dealer to be checked.

You have the option to extend the warranty for the gearbox to five years.
