Either the charger or the battery is faulty. Please contact the distributor.
Dealing with brake noise.
Please check the condition of the brake pads and discs. If they need to be replaced, please replace them in time. Also, please check if the installation position of the callipers is centred, and make sure there are no foreign objects stuck on the brake pads, check whether the discs are deformed, and making sure the discs and brake pads are not stained with oil. Please contact the distributor if is not the case.
Increases brake force.
Please check the condition of the brake pads and discs. If they need to be replaced, please replace them in time. Also, please check if the installation position of the callipers is centred, and make sure there are no foreign objects stuck on the brake pads, check whether the discs are deformed, and making sure the discs and brake pads are not stained with oil. Please contact the distributor if is not the case.
Excessive pedal effort, brake react properly. While slow pedal effort, it feels like have no reserve left.
Please contact distributor immediately. Possibly oil leaking inside the brake pump.
The grip of the tyre decreased.
Please check the wear condition of the tyres. If the tyres wear for too long, the rubber will be aged and It is recommended to replace the tyres after one year regardless of whether they are used or not. Excessive air pressure will also lead to a decrease in grip, please ensure that the air pressure is in the appropriate range (25-32PSI), different ground conditions and temperatures will also affect the friction of the tyres.
Wheels vibrating or rattling.
Please check if the spokes are loosened and if the axle is locked as specified. Also, please check bearings condition.
It does not start despite the switch being on.
Please check the condition of the belt, it might be the timing teeth of the belt are damaged or the belt is broken.
Chain loosen and make grinding noise.
Please adjust the tension of the chain properly to ensure that the free range of the chain is 1-2 cm length.
Chain makes rattling noise.
Please make sure the chain is properly lubricated and inspect each link for deformation or damage.
Broken spokes.
Please replace damaged spokes and have them re-adjusted by a professional.
Front Suspension Fork too stiff.
Please make sure that the sides of the fork are parallel. Loosen spring preload, turn down compression damping.
Back Suspension Fork too stiff.
Please make sure that the rear shock linkage pivot is smooth and spring preload is loosen, but not causing the spring to loosen. Also, turn down the compression damping.
Shock absorbers make noise.
Please check if there is foreign object on the exterior part. If the sound comes from the shock absorber itself, please contact the distributor.

After making sure everything is working perfectly fine, you can add a sponge pad of appropriate thickness to the bottom of the battery to ensure that there is enough pre-pressure on the battery when the battery compartment cover is locked.
What to do after crash riding?
Please turn off the power and check if that the front fork legs are parallel, if the handlebars are aligned or deformed, if the angle of the brake handle has changed, if the brake functions are normal, if the brake disc and chain plate are deformed and if the pedals and the bracket is damaged or deformed.
