DISCLAIMER
Maximum rider size
Correct assembly is essential to ensuring your safety and Rhino’s performance. While
you can assemble Rhino yourself, ZuGo Bike always recommends having a certified
bike mechanic check the bike before riding. If you do not have the necessary skills to
assemble your bike, please have a certified bike mechanic assemble and adjust it for
you.
Assembly and fit
The use of any accessory, component, or spare part that has not been approved by
ZuGo Bike may jeopardize the safety and performance of your Rhino, void your
warranty, and result in damage to your bike or significant injury. Doing so is at your
own risk.
Non-ZuGo Approved Accessories and Components
Please consult your State and local e-bike laws regarding any minimum age
requirements, maximum speeds, required safety equipment like helmets, and specific
road rules.
State and local laws
Always check the condition of your Rhino before you ride using the ZuGo Pre-Ride
Safety Checklist. Ensure you perform regular maintenance activities in accordance
with the suggested maintenance schedule outlined in this manual (see section 7:
Maintenance)
Safety checks and maintenance
Your Rhino is fitted with a powerful electrical system to help give you the best riding
experience on and off the road. Please familiarize yourself with all aspects of your
Rhino’s electrical system to include the battery, the display, the throttle, lights, and the
brakes. If any of these components are not functioning properly, please stop using
your Rhino immediately and contact ZuGo Customer Happiness Team.

BE ORE YOUR IRST RIDE
Rhinos are powerful e-bikes and they need to be operated with the same level of care and
attention as a motorized vehicle. Please do not ride your bike until you have obtained
adequate knowledge of your bike’s controls and functions. We want to make sure you ride
safely and have the best experience out there on the roads and trails!
Ensure you have completed all of the assembly steps in this manual
Double check your handlebars to ensure they have been pushed down to the insertion
line and the bolts are very tight
For your first ride, choose an open flat area with no obstacles or pedestrians. Start with
your setting as PAS 2, then apply a little throttle before starting to pedal (remember to
never push the throttle to full power from a complete stop!) . Play around with the different
ride modes, speeds, and turns. Once you are comfortable with the bike, there's no limit to
your adventures!
Refer to your state and local laws related to operating e-bikes (especially if you have
unlocked your bike to a Class 3 or 4) and ensure you have all of the recommended and
mandatory safety equipment (e.g. a well-fitting helmet) and meet any state and local
minimum age requirements
With the bike off, familiarize yourself with the bike’s features and components,
especially the battery, keypad, display, brakes, and throttle
Conduct a pre-ride safety check of your bike using ZuGo’s Safety Checklist

What to check before EVERY ride
Always remember to ride safely, follow local traffic laws, and wear a helmet!

RIDING S A ELY
2
Familiarize yourself with your local traffic laws. Abide by these laws and respect traffic lights
and signs
Always wear a helmet and any other necessary safety equipment
While on the bike and at a complete stop, you only need to gently press the throttle to
accelerate. If you push the throttle to full, you run the risk of injury
When braking, apply more pressure to the rear brake than the front brake. When braking on a
steep incline, squeeze the back and feather the front. The front is more likely to cause an error if
over-braked
Remain alert and look around for any hazards, including vehicles, cyclists, and pedestrians.
Respect pedestrians right-of-way
Ride single-file in the direction of traffic and avoid vehicle blind spots. If you need to pass
another cyclist or pedestrian, alert them before doing so
Use hand signals when turning and use extra care at intersections
Do not drink alcohol or take drugs before operating your bike
Using your phone or listening to music while riding is discouraged
Be considerate when parking by not blocking paths and building entrance points
Secure any loose clothing and wear reflective clothing if riding at night or in bad weather
Avoid riding in salt water or off of jumps to avoid damaging your bike’s components
Always carry identification, a phone, cash, as well as any emergency repair supplies

A SSEMBLING
YOUR RHINO
Your Rhino is already 95% assembled and only needs a few simple steps to be fully functional. You can
watch our 11 minute assembly video in our online help center or follow the step-by-step instructions below.
GETTING STARTED
WHAT YOU'LL NEED
A friend to help carefully lift the bike out of the box
A knife or scissors to open the top of the box and cut the zip-ties
Your Rhino parts box, which contains:
Pedals
Charger and cord
Toolkit (contains all the tools you need for assembly)
Touch-up paint
Footpegs
Miscellaneous screws
While assembling your Rhino should take no longer than 30 minutes, please take your time with each
step. We want to make sure your Rhino is ready to ride as soon as you’ve assembled it!
If you don't want to assemble your bike yourself, you can also take it to a local bike shop where they
can easily assemble it for a small fee.

Find a space with lots of room to work. Take
pictures of the bike’s box and note any
damage to the outside. Cut off the packing
straps on the outside of the box
Set the handlebars, front fender, cardboard
parts box, and front wheel aside and out of
the way. Cut the zip-tie that holds the front
brake caliper

Place the box upright and open up the flaps
on the top of the box (be careful not to rip
the box!)
Remove the foam packaging and lift the
bike out of the box (you may need a friend
to help) and gently place it on the ground so
it is standing on the rear wheel and fork
Using your hands, scissors, or side-cutters,
remove all of the zip-ties, foam, and
cardboard from your bike. Make sure you
don’t scratch your frame!
Pull the black plastic tab out of the brake
caliper

Slide the rubber boot down to the top of the
crown
INSTALLING THE HANDLEBARS
Pick up the handlebars and find the minimum
insertion line
Slide your handlebars into the two forks until
the minimum insertion line is just covered
With a 5mm allen key tighten the two allen
key bolts on the side of the fork. To tighten,
turn each bolt 1-2 circles to the right,
alternating bolts
Make sure you tighten the bolts until the two
“pinch bars'' almost touch and you cannot
tighten them anymore. Repeat on the other
fork
With your hands on the handlebars, without
squeezing the brakes, check if the levers are
the right height. Adjust them to a more
comfortable position with a 5mm allen
Make sure there is enough space next to the
throttle so it can be pressed to its full range
Do not squeeze the brake levers until your
front brake is installed
Make sure your bike is off when testing
the throttle
Don't leave the rubber boot up!

(continued)
Steps 9-15 relate to models that have a
quick release bolt on the front wheel. If
your bike has a bolt-on front wheel, the
process for inserting and tightening the
front wheel is the same, the bolt will just
look a little different!

With the bike still upside down, lightly press
down the front brake handle with your foot
to center the calipers on the brake before
tightening

While still holding down the brake lever,
tighten the two caliper adjuster bolts until
they are snug (not over-tight). Once they are
tight, you can release the brake
Spin the wheel to test if the wheel spins freely
and does not rub on the brake pads
If it sounds like the wheel is rubbing , loosen
the caliper adjuster bolts and try squeezing
the brake lever again to center the calipers. If
it looks like the disc is not centered between
the calipers, you can gently push the caliper
over with your thumb or finger until it is
centered over the disc. Tighten the caliper
adjuster bolts and release the brake lever
INSTALLING THE FRONT WHEEL
13 14
Screw the quick release cap onto the bolt so
it’s only attached by a thread (it should be
loose)
Slide the wheel with the rotor on the brake
side between the front forks and hook the
tabs at the bottom of the forks onto the
quick release bolt on either side of the wheel
15
While holding the non-lever end of the quick
release bolt steady with one hand, screw the
quick release lever to the right with your other
hand. Tighten it until it is HARD to close. Flip
the lever into the “close position”
Note: if your bike has a bolt-on front wheel, make
sure the nut and washer are on both ends of the
bolt and tighten them with a 15mm wrench
WARNING: An improperly secured front wheel can
cause loss of control, accidents, serious injury, or
death. Check that the front wheel is properly
secured to the bike during assembly and before
each ride.
