FAQ
-
What do I do if my fork is no longer performing to the level it was when new?
Please have your local bicycle retailer perform a quick diagnostic check on your fork.
-
What type of lubrication should I use on the forks wipers?
SR SUNTOUR recommends our factory Conpanna grease or a Teflon-based lubricant after every 25 hours of use.
-
My fork is leaking oil.
All SR SUNTOUR forks are lubricated from our factory using proprietary grease. This grease can break down over time and have an oil-like appearance. It should be wiped away from the stanchion tubes with a clean, dry rag. Over the course of time, new grease should be applied at 50 hours of use or sooner.
-
Air releases out of my fork or shock when I remove the pump. How do I know the air pressure has been set to my sag adjustment?
This is normal and the air is actually coming from the pump, not the shock or fork. When re-attaching the pump, it can take 10-15 psi to pressurize the pump causing the gauge to display a lower pressure than what was in the air spring.
-
What is sag?
Sag is the initial amount of fork travel when you are resting on the bicycle with riding gear. This adjustment allows for optimal performance and travel of your fork or shock.
-
How much sag should I have?
Generally speaking, forks that have less than 120mm of travel should strive for a 15–20% sag adjustment. Suspension forks with more than 120mm of travel should be set at 25–30% sag.
E-BIKE SYSTEM (HESC) SUPPORT
-
What is the meaning of the word hesc?
HESC means "Human Electro Synergy Components".
-
What is the battery charging time?
The batteries need four to five hours to fully recharge. This process may vary according temperature and air moisture.
-
What is the best way to store the batteries?
Preferable storage condition is 40~50% charge level at 15~25℃. If the battery level becomes less than 40% of its capacity, it is recommend to re-charge the battery. It is recommended to check the battery every three months in order to keep the battery capacity at the minimum 40%.
-
How long will the battery last?
Battery life is influenced by the number of charging cycles and storage conditions. Store and re-charge the battery at a temperature between 15~25℃. See the manual for more details.
-
How many times can a battery be re-charged?
Minimum 500 times. See the manual for more details.
-
How do I know when to replace the battery?
When battery gauge on the display doesn't reach100%, even if re-charging for long periods.
-
Is it possible to re-charge the battery without first using up the full capacity?
Yes it is possible without harmful effects.
-
Which type of battery is used with the SR Suntour ebike system?
It is a Li-ion type battery. The benefits of Li-ion batteries are: 1) Holds a charge longer in storage. 2) Minimal "memory effect" (additional repeating charging is possible). 3) Compact, yet larger capacity is possible. 4) Light weight.
-
The pedaling feeling is suddenly heavy. What is wrong?
1) Check Assist mode in order to make sure that the correct Assist mode is selected. 2) Check the battery level. When battery level becomes too low, the Assist feeling might be reduced according to the battery level. In that case, re-charge the battery.
