Sur-Ron light bee has a certain waterproof ability when it is designed. It is recommended that the wading depth should not exceed the motor, and the chain and bearings should be maintained in time after riding in water.

Brake power-off protection, tipping power-off protection, side bracket power-off protection, over-current protection, over-voltage protection, over-temperature protection, over-discharge protection, over-charge protection, locked-rotor protection, steering wheel speed protection.

Due to regulatory requirements, the lights have no on/off switch and are always on. Regards to the overall power consumption is very low and it can be ignored.

Due to regulatory requirements, It is not recommended to turn off.

It is recommended to use it in the range of 0 degrees above and below 40 degrees. Too high or too low is easy to damage the battery or activate the protection function.

The original manufacturing belt can be used for more than 15,000 kilometres under ideal conditions. Considering the unpredictability of the usage scenario, it is recommended to check every 500 kilometres and replace it every year. In the case of more off-road use, check each time and replace it every six months.

With regular maintenance and lubrication, the chain has a longer service life. The chain will gradually become loose with the wear and tear during use, it is necessary to adjust the position of the rear wheel to adjust the tension of the chain, and keep the top and bottom free range of the chain at 1-2 cm. It is recommended to replace it every 10,000 kilometres.

The power system design of the two models are different, and it is strictly forbidden to use different types of batteries.

The original manufactured front fork has the same specifications as the straight-tube front fork used in downhill mountain bikes. The length of the rear shock absorber is 267 mm, and the size of the bushing is 24*8 mm. The original shock absorber has a special modification, please make sure to fully understand the risks brought by the modification if you are going to modify it yourself.

Compatible with four-piston brakes of downhill bike specifications, the original manufacturing brakes have a special modification. Please be cautious while planning for modification.

The original manufactured handlebars use a 31.8mm mounting specification. Please do not use a handlebar that is lower than the strength of a downhill bike.

The original manufactured tyre size is 70/100*19 and is a customised specification tire. Replacing other tyres may affect the performance.

The power supply of the original lamp is 12V30W. Please do not exceed this specification as it will damage the original cable.

The original manufactured frame, power system, battery, controller, and motor are strictly prohibited to be modified. Any related modification will automatically waive the manufacturer’s warranty, any risks shall be borne by the user.

Please contact the distributor if is not the case.

Please contact distributor immediately. Possibly oil leaking inside the brake pump.

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.

Please check if the spokes are loosened and if the axle is locked as specified. Also, please check bearings condition.

Please check the condition of the belt, it might be the timing teeth of the belt are damaged or the belt is broken.

Please adjust the tension of the chain properly to ensure that the free range of the chain is 1-2 cm length.

Please make sure the chain is properly lubricated and inspect each link for deformation or damage.

Please replace damaged spokes and have them re-adjusted by a professional.

Please make sure that the sides of the fork are parallel. Loosen spring preload, turn down compression damping.

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.

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 there is no other source of oil stains, please contact the distributor regards to the issue. Please note that it is normal for a thin oil film on the shock absorber inner tube.

Please check if the battery support base is damaged, the front support plate of the battery compartment is deformed, the battery compartment cover is damaged, or the rubber spacer is missing or displaced. 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.

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. Also, please check if the accelerator handle is damaged or smooth. Lastly, turn on the key to check if the vehicle is working properly.

Please loosen all the front fork’s screws, then loosen screws on the side of the handlebar, and tighten the screws of the upper cover to ensure that there is no obvious resistance to turn the handle, and then lock the middle of the upper connecting plate’s large screw, then tighten all the fastening screws.
