Please accept our sincere gratitude for your purchase from all of us at Burromax.

A Note about the Model you Purchased

The HRH and HRS share similar components apart from the handlebar, tires and gear ratios but we had two very different ideas for use.

The HRH was intended as a Trail Bike with dirt knobbie tires, slightly lower speed and higher torque allowing for low-speed riding in hills and wooded areas where Trail Riders and Hunters might find themselves. We have Racks, Saddlebags, Coolers Bags and other accessories to help make this a great part of the outdoor Trail Riding/ Hunting Experience.

The HRS has a Pavement tire with higher gear ratio and favors lighter riders where it has a slightly higher top speed and smoother all-around performance where Pit Bikes might be handy at tracks and events where pavement is abundant. This bike performs excellent as a base for media folks and photographers who will also like our many accessories for hauling stuff around. The HRS is also a great ride as a pit bike for racers, of course.

Both bikes are very customizable in performance and are tuned to provide a reasonable performance/range combination.

If you have additional questions about performance upgrading or range extending call us at 18007421189 and we will do our best to help you personalize your bike and experience to fit your needs.

Carton Contents

Located within top of the packing foam you will find the Battery Charger, Front Fender, Rear Fender, Right and Left Footrest assemblies, Handlebar Clamps, all hardware and Tool Kit. The Front wheel is located at the bottom of the packaging.

OPEN THE TOP OF THE SHIPPING BOX and Remove the contents from the top of the foam inserts. Inspect and confirm that you have all parts and Hardware. Remove the foam separators that protect the components from damage during shipping. Remove the Front wheel and brake rotor. Inspect the contents of the box for scratches in the paint, dents or kinked Brake lines that may have occurred during shipping. Because these vehicles are 90 percent assembled and packed at the factory, there should not be any problems, even if the box has a few scars or dents.

Allow up to 30 Min for assembly.

Check for all parts and hardware before beginning assembly. Follow these instructions carefully, Checking all bolts, Nuts and screws for tightness during the assembly process. DO NOT Squeeze the brake levers until the brakes have been fully assembled

Set the bike on a stable platform at least 18” off the ground.

Position the front fork so that it hangs off one end of the platform to facilitate front wheel and brake assembly installation.

Enjoy the process and take your time to ensure all components are secure. Checking all bolts, nuts and screws for tightness during the assembly process

Attaching the Handlebars and Wiring

Tools required: 6mm, 5mm, 3mm,2.5mm Allen wrench

Place the handlebars in the Lower handlebar clamps on top of the Front fork. Make sure brake lines are not twisted or kinked and wires are free from the clamps. Loosely Install 2 top handlebar Clamps and (4) 8mm allen Bolts.

Center handlebar in clamps and position straight up or slightly forward to fit rider height. Tighten the bolts using a 6mm Allen wrench. When properly tightened the handlebars should not move forward or back.

Attach the wires

The wires have color coded ends and will only fit to the same color connector. Put the wire ends together and rotate slowly until you feel the connectors align with each other. Then gently push together until you feel the connectors snap into place. Do this with all wire connections for each side of handlebar

Brake levers and throttle

DO NOT Squeeze the brake levers until the Front Brake has been fully assembled to the bike.

Install the front and rear master cylinders onto the handlebars using a 5mm allen wrench taking care not to twist the brake hoses.

Rotate the throttle to a good operating position and tighten using a 3mm allen wrench. Rotate the headlight and horn switch to a comfortable position and tighten using a 2.5mm allen wrench. Turn the front fork from side to side making sure that the wires and brake lines are free from binding and clear of the fork stop located behind the headlight. Use wire ties supplied to group wire together. -Do Not Tighten wire ties too much or you can break the small wires inside.

Installing the Front Fender

Using (3) 6mm allen bolts, attach the front fender to the bottom of the lower fork clamp above the front wheel and tighten securely with a 5mm allen wrench. Remember the fender is plastic so do not over tighten bolts.

Installing the Front Wheel

Install the front axle into the left fork leg far enough to install the first wheel spacer. Hold the front wheel up with the Brake rotor to the brake caliper side of the front fork and insert the axle into the wheel. Twist the axle back and forth to slide it through the bearings and spacer in the wheel. Install the 2nd wheel spacer between the fork and wheel on the opposite side. You may have to spread the forks slightly to get the spacer in between the axle and fork. Slide the axle all the way through the forks and install the axle nut. Tighten Securely. Make sure the front wheel spins freely after you have tightened the axle nut.

Installing the Front Brake Caliper

DO NOT Squeeze the brake levers until the brake has been fully assembled to the front fork and brake rotor.

Remove the caliper mounting screws from the brake caliper or caliper mount bracket on the front fork. Remove the plastic spacer located in between the caliper brake pads. Install the caliper over the Brake Rotor, align the mounting holes and install the mounting bolts (Fig 1) hand tight. Before tightening the mounting bolts, loosen the caliper adjusting bolts (Fig 2) 1/2 turn so that the caliper is loose on the mounting bracket. Once the caliper adjusting screws are loose, you can now tighten the caliper mounting bolts.

Adjusting the Brake Caliper

After you have tightened the brake mounting bolts, squeeze the brake lever a couple times to set the position of the caliper. Squeeze the brake lever one more time and hold pressure on the lever while tightening the caliper adjusting bolts (Fig 2). This will align the caliper and brake pads. The rotor should be running parallel and central to the caliper body. When depressed the brake lever should be approximately 1 inch or more off the hand grip and have a firm feel. The front wheel should roll freely without dragging on the brake when this operation is completed.

Installing The Rear Shock

The Rear shock is mounted to the upper frame mount under the seat. Lift the back of the bike up enough to swing the shock down into place and install the special 2-piece lower shock bolt provided in your hardware package.

Install the Rear Fender

Using (3) 6mm allen bolts, attach the Rear Fender to the top of the Rear Fork just behind the rear shock. Tighten securely with a 5mm allen wrench. Remember the fender is plastic so do not over tighten bolts.

Checking the Tire Pressure

Both tires should be set to 40-45 PSI. We strongly recommend 45 PSI for persons over 175 lb. when riding this product. Proper Tire pressure is VERY IMPORTANT. Do not squeeze the tire and assume it is correct.

For the best performance and range this must be checked regularly. Low tire pressure reduces range, speed, and all-around performance.

Please Note: There is a tire information label located on the left side of the rear fork with this information as well.

Installing the Footrests

The footrests are made to fit on the right and left. MAKE SURE YOU ATTACH THE FOOTRESTS SO THAT THEY FOLD TOWARD THE BACK OF THE BIKE. Using (4) 10mm Hex bolts and lock nuts attach the footrests and brackets to the bottom of the frame just below the battery box. Using 14mm/17mm wrenches Tighten the bolts and nuts securely.

Operation and Functions

Key Switch Operation

All HR Series minibikes come with keyed switches so that use can be restricted to owners and parental control is available. We send 2 keys with each unit, and we highly recommend you save one of these keys in a safe place. The HRH/HRSA has a three (3) position switch. The first position (1) is OFF, the second position (2) allows all lights and USB ports to operate without power to the motor. This is useful when using the lights, charging cell phones and using other accessories without the possibility of the vehicle taking off due to someone accidentally twisting the throttle. In the third position (3), Lighting, USB port and Motor are all ON and the Bike is Fully Functional

Two Position Switch

The charger has a small window with one LED to indicate the charge status. A Green Light indicates the charger is on or ready and a red light indicates the charger is charging. When the battery is fully charged the indicator will change from a red light to a green light signifying the battery is fully charged. The charger will get warm during use, this is normal and is no cause for concern. These chargers are equipped with a small fan to keep it cool during operation. Do not store or use this charger in areas where dirt or debris can get into your chargers' fan. These chargers will often keep running the cooling fans even after the battery has reached full charge. This is normal operation and if your charger does not get warm during use, it does not mean that it is not working properly.

Charging the Battery

Your HRH/HRS has a charging port located on the left side of the battery box as shown below. To access the plug, rotate the charger port cover away from the Battery box housing. This plug must be orientated properly for the plug to connect, and the charger plug can easily be turned until the charger port pins align allowing the connection to be made.

For the first 5 charge cycles we recommend that you discharge the battery to 47- 45 volts when vehicle is at rest and then fully recharge, uninterrupted until the battery is full. Typical recharge time: up to 4 hours, depending on level of depletion and quality of power source. After the first 5 discharge cycles, shorter charging times or partial charging is okay. You will get over 75% charge in 3 hours. There is no need to fully cycle the battery every time you ride with Lithium batteries. You can ride for an hour and charge to full again if you like. When the minibike is not in regular use, store the battery at 50-70 percent full. Turn power switch “OFF” before charging and conducting any maintenance procedures. Expect up to 400 charge and discharge cycles. Charging and discharging the battery in extreme temperatures above 110° F and below 32° F can cause damage to the battery.

The Burromax Li-ion battery and charger are to be used together. Do not use chargers from other model bikes—USE ONLY Burromax battery chargers at the correct rated voltage.

WARNING: Rechargeable batteries are only to be charged under adult supervision. Always disconnect your electric minibike from the charger when the battery is fully charged and before cleaning. Do not use chargers that have similar plugs and assume it is OK. USE ONLY Burromax CHARGERS WITH Burromax PRODUCTS

Modes of Operation:

3 Speed Throttles

All HR and XR model Burromax electric bikes use a new speed selection arrangement where the Black button on the handlebar controls the 1rst -2nd speed selection (low speed and medium speed) and a hidden switch on the side of the battery compartment on the left side of the bike controls 3rd speed (or maximum Speed) (See Fig 5A)

All bikes come shipped in Low Mode (1-2 speed mode) and we suggest this mode for general use for most people. If you choose to use the bikes in the 3rd speed mode, you will deplete the battery very quickly and the bikes are very powerful in this mode. We have included a fuse in these bikes that automatically shuts the bike off after approx. 30 seconds of maximum effort operation. This allows for 15-30 second burst of speed and will keep you from overheating the battery/controller or motor. Do not repeatedly use this bike at maximum effort or you can overheat the battery and cause it to shut down, or, you will have to wait for the battery to cool before recharging the battery.

There is a small hole in the battery side cover Allen bolts (fig 5 A) and with the key switch in the on position you can insert a small tool and depress and release the switch. Look at the gauge for a change in the lower center area for an ‘S” to identify that all 3 modes are available. If you repeatedly hit the speed button in will provide 1-2-3-1-2-3 operation and it's no problem to go to any speed setting while moving.

The 1-2 and hidden 3 speed setting was designed for people who want others to ride and not be able to easily reach a switch that drastically improves performance and top speed. Low speed (1) has a soft and easy throttle mode and will have the longest riding range. The Medium Speed (2) increases torque but still a limited top speed for additional power when pulling hills. The High Speed (3) switch should only be used with experienced riders for burst speed and power needs sparingly. This mode will deplete the battery quickly and is the most stressful for all components. Heat in the Battery, Controller and Motor components can rise quickly in this mode.

Side Light Operation

Your Burromax is equipped with LED side lights for rider safety, and they are very useful in pit areas or camping to provide light for the area. To turn these lights on and off you can depress the hidden switch located in the center bolt of the controller cover housing (Fig 5B) using a supplied key blank on your key set. This is a push button switch so press once for on and once for off. Your setting will remain until changed.

Throttle programming :

3 Speed throttle Speed alteration

All HR and XR model Burromax electric bikes come with a programable speedometer that allows you to changing gearing and tire size substantially and still be able to set the correct speed on the throttle. We have many people who enjoy being able to customize the gear ratios or tire sizes and this allows speed calibration. This does require downloading an APP (such as --Pedal Speed Machine) or checking speed with another method

1. Ride the bike with the altered gear ratio or tire size and using a pedometer APP, GPS or other method, compare you actual GPS speed to given speed on the gauge-make note and Calculate change needed-Example: You ride the bike and the Speed given was 33 but actual speed was 30 (10 percent difference will be the change)
2. Begin program process—Install the small key blank provided with key set into the hidden speed selection hole (fig 5A above) in the battery box.
3. From the off position, turn the key to run position and quickly press the hidden speed switch (described fig 5A above) 6 times (within approx. 5 seconds) watching for the gauge readout to change—make note of the initial number shown as soon as it enters program mode.
4. The gauge will switch into program mode and begin counting by 2 from the base programmed number it was installed with from the factory (somewhere between 86-100) depending on the model, gearing and tire.
5. The throttle will count to a maximum of 150 and then go back and begin at 50 (minimum). These numbers represent a percentage of change.
6. Once you have entered program mode the throttle will count until you stop it by pressing the hidden speed selection button (Fig 5A) --to stop counting simply hit the hidden speed selection button again. If you made an error, resume counting by hitting the button again (if you miss your number).
7. Once you have stopped at the desired number, stop and wait about 10 seconds for the throttle to reprogram--Turn the key off. Your throttle has been recalibrated.

In the simple example given, to change the gauge from 33 to 30 MPH would require a 10 percent change or 10 number change from the base setting (started with 100-change to 90) See our online video as well at www.burromax.com.

MPH to KPH- Hold rear wheel off the ground while accelerating to 6 (mph or Kph) hold for 1 min at speed for change to occur from one standard to the next

Features and Controls

The HRH/HRS is equipped with Hydraulic brake systems front and rear using Mineral Oil fluid. These Brakes should be inspected every month or 100 miles and replaced when the pad is getting thin. Pads are inexpensive, replace when they are under 1/16 thick. Burromax stocks replacement brake pads and they are relatively easy to replace. It's important to check the pads regularly – if they wear out right down to the backing plate, metal-on-metal contact will destroy brake rotors very quickly.

You also need to check for leaks, loss of fluid. If you are unfamiliar with hydraulic brakes, you may find it better to have a good bike repair shop do the inspection if needed.

If you need to replace the brake pads, start by removing the caliper from the brake mounting bracket. With a large flat head screw driver spread the pads apart until both caliper pistons are fully pushed back into the caliper and the pads are as far apart as possible. Remove the split retaining pin holding the brake pads in place. Remove the pads and spring using needle-nose pliers. At this point it's a good idea to clean the inside of the caliper and rotor with a little brake clean degreaser and paper cloth, to remove any brake dust or dirt build-up. Install the new pads along with the retention pins and spring clip.

If you need to replace the brake disc, now is time to remove the wheel and replace it. When reinstalling the wheel make sure that you reinstall the spacer in the correct locations and the wheel rolls freely after the axle has been properly tightened.

Install the caliper over the Brake Rotor, align the mounting holes and install the mounting bolts. Before tightening the mounting bolts Loosen the caliper adjusting bolts (shown in Figure C) 1/2 turn so that the caliper is loose on the mounting bracket. Finish tightening brake caliper mounting bolts. You might have to squeeze the lever several times before the pads engage. Squeeze the brake lever a couple more times to set the position of the caliper. Squeeze the brake lever one more time and hold pressure on the lever while tightening the caliper adjusting bolts. This will align the caliper and brake pads with the rotor face. The rotor should be running parallel and central to the caliper body. When depressed the brake lever should be approximately 1 inch or more off the hand grip and have a firm feel. The wheel should roll freely without dragging on the brake when this operation is completed.

Testing the Brakes

To test the brake, squeeze the lever to increase the pressure on the brake. When depressed the brake lever should be approximately 1 inch or more off the hand grip and have a firm feel. The wheel should roll freely by hand when the brake is not applied, and the brake should lock up when applied with force.

WARNING: Hard Braking or loose terrain can cause the electric motorcycle to skid the tire throwing an unsuspecting rider. Practice in an open area free from obstacles until you are familiar with the brake function. Avoid skidding to a stop as this can cause you to lose control and wear the tire prematurely.

Note: Brakes that are poorly adjusted can be draggy and will cause excessive wear and poor performance.

CHAIN ADJUSTMENT, REAR TIRE AND CHAIN REPLACEMENT

Tools required: 5mm Allen wrench, 2- 10mm wrenches, 14mm, 17mm wrench and Chain Lube.

Set the bike on a stable platform so that the rear wheel is off the ground. To adjust the chain only perform steps 3, 6, and 7

To replace and adjust the Chain perform steps 1, 3, 5, 6, and 7

To replace or repair the rear tire perform steps 1, 2, 4, 6, 7, 8, 9, 10,

Use a 5mm Allen wrench and remove the chain cover screws and slide chain guard to the back of the minibike.

1. If replacing the tire remove the two-brake caliper mounting bolts (5mm Hex Key) and remove the caliper.
2. Adjusting or replacing chain only use 14mm and 17mm wrenches, loosen the axle, approximately 2 full turns
3. Remove the rear wheel, remove axle nut and axle and remove the chain from the sprocket--pull the wheel out. Note the sequence of the hardware for assembly.

1. Install the new chain by lacing the chain around the motor sprocket. Maneuver the chain onto the sprockets on the rear wheel and motor. Pull the chain tight. Place both ends of the chain at 10 o'clock on the rear wheel sprocket. This will make it easier to install the master link. Slide the master link into the chain with the pins out, place the outer side link onto the protruding master link pin. Push the link together so that you can see the retaining clip grooves in the pins. Lay the retaining clip over the pins with the open end toward the back of the bike and slide the clip in place using a pair of pliers. Make sure the clip is locked in place.

Chain and Sprocket Notes:

The chain will typically have a “loose spot” and “tight spot” corresponding with a sprocket rotational position. This is normal and common to all chain-driven products due to run-out tolerances of the sprockets. The chain should be adjusted to the ideal tension with the chain in the tightest spot.

Proper chain alignment must be maintained. The wheel must not be skewed. If the chain is noisy or rough running, check the lubrication, tension and alignment of the sprockets, in that order.

WARNING: To avoid a pinch or injury keep fingers away from moving sprockets and chain.

Battery Replacement

WARNING: Make sure the power switch is in off position before performing any maintenance.

Temp Sensor Protection note: Li-ion battery (1-52v-30ah) contains a non-replaceable internal temperature sensor and will turn off when the internal temperature reaches 75C. The battery will not accept a charge if the internal temperature reaches 55C and will require a cool off period before charging is allowed. This does not mean the battery is defective and is present to keep users from overheating the battery during aggressive use. If you experience cutoff of discharging or charging you need to ADJUST YOUR RIDING STYLE to a less aggressive style

Only use the Burromax Li-ion battery and Li-ion Battery charger together. Do Not attempt to replace this battery with anything other than the OEM battery

1. With the battery cover removed, disconnect the hold down strap.
2. Slide battery set out of mounting tray.
3. Disconnect battery connection and the charging port connection. Re-install new battery and reconnect.
4. When reconnecting the new battery you may get a small spark—this is normal.
5. Tuck in wires and reassemble.
6. See www.burromax.com for ordering.
