    UNBOXING/SETUP
    Now before you act like a 5year old on Christmas and unbox it and assemble it there are some thing you should know! You really need to watch the following video before trying to unbox your bike, trust me it can save you time and money. but before you do there are different versions of the front fork, in the video we cover the RST fork only so please make sure that you read the appropriate section first. Be careful when removing the axle lock nut, some are reverse threaded so look at the bolt it will show you the direction, if you turn the wrong way around the bolt will snap without much force.


    For the New RockShox RC Boxxer please click to download the installation manual as the axle is a little different and need to be tighten properly.

    SUPPORT NOTES: This new fork uses the new axles system called "Boost axles" So for the Sur-Ron front wheel to fit this fork there is a disk brake spacer installed.. So if you replace the front disk or the front wheel make sure to re-install the disk spacer. Click here to see the difference between boost axle VS the normal axle

    DNM USD8S fork. Make sure the axle bolts and the pinch bolts are tightened correctly, before each couple rides, If you loose or break them you will likely have to source them on the web as we do not always have replacements for these in stock, can take several weeks to get them from the factory.

    For the RST Just follow Matt's unboxing video down below!






    BEFORE RIDING

    1. Charge your Battery
    2. Go over all the bolts before your first ride, especially the axle bolts and the fork bolts on the crowns to hold the fork legs in place. please refer to the torque setting chart down bellow.
    3. Use that cardboard box as a stool and put the bike on it, check if both brakes work fine and if the pads dont rub too much on the disks. If the brakes are spongy or if you have too much drag you will have to so a brake adjusment or bleeding.
    4. Check the tire pressure, too low and you can pinch the tube or rip the valve off due to slippage. Too much pressure and it wont ride good off road. Anywhere between 18-30psi on the stock off-road tires is good.
    5. Chain tension, it seems like they ship the bikes with lots of chain tension but you might find that loosening it up will get you less noise and less drag, This is unlike any motorcycle were the chain tension gets higher when the suspension compresses so it's easier to figure out the right tension from the start. You should be able to move it up and down half a inch up to an inch, if it's too tight you will put too much tension on the drive train and also it will not ride as smooth. Too loose and the sprockets will wear off faster, way too loose and you can lock up your wheel while riding (not fun at 40mph).Please click this link to know how to setup the chain tension properly.
    6. If you have the pedal kit install, make sure you checks each bolt/nut on the freewheel and bottom bracket assembly.
    7. Move over to the rear and check if the rear axle is solid & suspension components are secured. If the rear spring is loose then you much tighten the lock nut (click here)
    8. Check Spoke tension and recheck them after a few rides, they can come loose and you can rip nipples out of the rim or worst. If unsure how to properly tighten spokes and true a wheel, please take the wheel to a trusted motorcycle or MX shop or even a local bicycle shop can do it.
    9. Oil the chain, it should be lubricated from factory but it' always better to check. If the chain is too dry lube it with motorcycle chain lube, dry or wax type lubes are good for dry/sand offroad or street riding. Wet lube is best for wet/muddy trail riding environment. If you have the gold O-Ring chain then it's all good.
    10. Check the front fork, lock the front brake and put your weight over the handle bar to compress it, make sure you can at least go half way in. Adjusting the compression knob (top right blue knob) will change that so you can add more if you are a heavy rider or someone that jumps alot! If the fork does not come back up fast enough from a compression or too fast, then you can adjust the rebound (blue knob under the right fork leg)


    And please wear a proper helmet (DOT full face dirt bike and goggles) and protection gear, this is a 40+ mph fun bike and last thing we want is for you to get hurt!

    SUPPORT NOTES:

    Some Light-Bee X (LBX) were shipped in street legal mode , So if you bike is slow can't go any faster please check out this link to unlock the offroad mode

    To change from KM/H to MPH please turn off the key switch and press the little red button beneath the display and hold while turning the key swtich continue to hold the button for 3 sec and release.

    Road salt and saltwater
    As with any electric vehicle, saltwater can be damaging as it affects the electrical conductivity of circuits which could short circuit. You should not expose to saltwater. To protect against this you can use dielectric grease on any electrical connector. It is an easy addition and recommended if exposing to water in general.



    MAINTENANCE:
    It's an electric bike so not much with the motor and battery!

    Once every 60 miles or so (may depend on your use) it may seem a lot but this is a 45mph bike and the maintenance should not be any different than a gas dirt bike:

    Long term maintenance:

    • The fork, shock, pivots, motor mounts, belt tension should be inspected after a couple months or few hundred miles ... all bolts and nuts inspected basically.
    • For a hydraulic bleed kit this will work (The hydraulic brakes use mineral oil)

    Storage of the battery
    • The battery will self discharge ( the smart BMS remains active). So if you leave it unplugged for a few weeks then it's your duty to check the battery level at least every month to be sure that it's around 40-60%. If you let it drain to 0% it can be jumpstarted back to life. It can take a few jumpstart to get it to charge normally.

    Battery maintenance

    IMPORTANT: NEVER LEAVE THE BATTERY CHARGING UNATTENDED OR OVERNIGHT WHILE SLEEPING! Li-ion is safe to use but like any energy storage device there are some risks associated. If you would like to know more safety concerns with Li-ion click here

    VERY IMPORTANT: Never ever attempt to charge a frozen Li-Ion battery that is under 32 deg F (or 0 deg Celcius) Below freezing permanent damage will occur if you try to charge your battery pack. If your pack is frozen bring it inside your house and let it sit for a few hours till the battery is over 50F (10C) READ MORE HERE.

    IMPORTANT BUT NOT CRITICAL ;) : The battery needs to be charged prior to the first ride. The packs are shipped with 30-50% state of charge only! Always plug the charger in the AC outlet before connecting the charger to the battery.
    Please fully charge the battery to 100% for the first few cycles(3-5), leave it on till the charger stops...can take up quite a few hours ( anywhere from 2 hours to10 hours, depending on the capacity and charger rate). Remember to charger the battery when it's at room temp (not hot or freezing).

    Simple charging FAQ's (if you don't' want to read all the rest)
    -After a bike ride do not charge the battery yet, let it cool down for an hour or more.
    -After a charge, let the battery rest for an hour or two to cool down but also to let the BMS balance the cells.
    -Charging 80% and discharging to 20% are best for a long live!
    -It's OK to charge it to 100% to get more range, just don't let the battery sit at 100% for more than a day for no reason.
    -Standard BMS only balances to 100% (top balance), only really expensive smart BMS can balance at any voltage so far only the Luna APEX has one.
    -Balancing is slow so that's the reason to let the battery sit after a charge
    -Balancing can take a couple 100% charge cycles to complete.
    -When new a battery may take 6 to 8 charge discharges to ballance. Possibly more if you push the pack hard.
    -When new its always advisable not to discharge the pack at high amps until its balancing well.
    -Don't leave the charger unattended, charge in a safe place and unplug the charger when done to avoid a drain on the battery.
    -100% is about 58.8V on a 52V...if yours charger charges to 58.6 or 58.9V it's fines no worries.
    -Its also important that when running the battery to 10% or lower you risk tripping the BMS. When this happens the charger may not want to start. If this happens then you will need to Jump start the pack. Refer to this link if you charger fails to start.

    NOTE: this manual may be out of date and not
    reflect the newer models with different shocks/fork


    Sur-Ron front suspension additional info:

    The
    Sur-Ron light bee came from the factory with many different forks, 4 models so far.

    The first shipment of Sur-ron came out with a Fastace Air inverted fork, this is the manual for it:

    Support note: This manual only covers the dual air chambered FastAce fork that came in with the first batch of Sur-Ron in 2017. If you have a FastAce fork from 2018+, chances are that you have the spring version and you won't have air filling valves on the right leg.

    FAST ACE FRONT SUSPENSION MANUAL

    The Fast-Ace axle end bolts are hard to get if you loose them , they are M14x1.5 and thread length is 25mm.

    Make sure to buy a Grade 12.9 bolt to make sure you get a hard bolt. eBay has a fantastic selection of nuts and bolts if needed.


    The Second wave of Sur-Ron have the RST Killah fork, simple anad effective fork, maintenance free with external compresion and rebound adjustment. Just need to clean and lube the stanchions and dust seals For The RST axle and lock-nut replacement please see this link

    The 3rd wave of bikes came in with DNM USD-8 forks, they will require maintenance over time depending on your use, Your local mountain bike shop can probably do that for you!

    The Sur-Ron X black edition came with the RockShox Boxxer RC 2019 fork, so for setup and maintenance please refer to the SRAM website were you will find all the info on it :
