SAFETY FIRST
If you are unfamiliar with any aspect of the information included in this manual, it is
recommended that you take your VOLT and this manual to a local bike shop for
inspection, assembly and instructions.
• It is extremely important that you follow the safety guidelines contained in this manual
in order to ensure maximum safety for you as well as maximum durability of your VOLT.
• WARNING: Before you ride your VOLT for the first time, please be absolutely sure that it
has been correctly assembled. You will find step by step instructions in this manual. For
further clarification, you can also visit our website, https://ohwowcycles.com. But if for any
reason you are not completely certain, please bring it to your nearest bicycle shop.
• WARNING: Key assembly steps that must be properly completed with absolute certainty
(to include secure fastening) are pedals, saddle height, handlebar (both rotation and
height) and wheels.
• WARNING: Please ensure all safety latches, including quick releases and rings, are locked
in place and snug without any movement.
• WARNING: Please ensure all bolts (including the front/rear wheels, saddle bolt and brake
rotors) are properly tightened. When securely tightening handlebar bolts, be sure that the
space between handlebar stem and topcap (exposing handlebar) is of even width on
both sides of the handle bar. Failure to do this can lead to stripped bolts, or handlebar
coming loose. Certain components must be tightened to exact specifications using a
torque wrench for safety assurance. Fixed front wheel axlenut: 28-32Nm, Fixed rearwheel
axlenut: 30-35Nm, Handlebar bolts: 6-8Nm, Handlebar stem bolt: 13-15Nm, Barend bolts:
4-5Nm, Saddle bolt: 22Nm.
• If you are unfamiliar with cycling, we suggest that you take a cycling course that
includes safe riding.
• Test your brakes prior to using the VOLT every time. In wet or icy conditions, use extra
caution.
• Frequently check your tire pressures. They should be pumped to 2.0 bar (30 psi).
• Low tire pressures can result in damage to the tires and rims. It can shorten the lifespan
of your VOLT as well as cut your ride short if you suffer from a flat tire. It can also
compromise the handling of your VOLT which can make it more difficult to control.
• We recommend that you always wear a helmet when riding any VOLT.
• Please observe all traffic regulations and other applicable laws, including any lighting
laws.
06

SAFETY FIRST
• Don’t drink and ride. Even a small amount of alcohol can impair your judgement, lowering your
ability to remain safe on your VOLT.
• Weather and night time operation can be tricky in inclement, icy or snowy weather and at night.
Do take necessary precautions.
• Don’t lend your VOLT to anyone who is unfamiliar with it. If you choose to lend your VOLT to
anyone, make sure they have also read and fully understand this owner’s manual.
• VOLTs are not toys. All riders must be at least 16 years old.
• Minimum leg length allowance allows for no less than one inch of clearance between (1) the
top tube of the bicycle and the ground plane and (2) the crotch measurement of the rider.
• All VOLTs are meant to be ridden by a single person. Total recommended weight of rider,
including all items such as backpack, is 150 kg (330 lbs) for the VOLT model.
• Your VOLT is intended for riding on both street and light off-road. It is not recommended to be
used on other surfaces as it can be dangerous and lead to an accident.
• It is advisable to be extremely cautious when riding in traffic. Cars are not used to the speed at
which a VOLT can travel, as compared to a regular bike.
• Since it is impossible to anticipate every situation or condition which can occur while on the
VOLT, this manual makes no representation about the safe use of the VOLT under all conditions.
There are risks associated with the use of any transportation vehicle like a VOLT. These risks
cannot be predicted or avoided, hence they remain the sole responsibility of the rider.
• When you need to replace the battery, please either dispose of it properly or send it back to us
or your local bike shop to ensure that it is properly recycled.
• WARNING: Do NOT take apart OR repair parts by yourself as this can compromise its safety and
will void the warranty. Please go to your local bike shop that has experience with eBikes. If In
doubt, please contact [email protected]

that only assist the rider when pedaling, iii) no throttle function – save for the walking assist
function of maximum 6 km/h), iv) only providing assistance to a maximum top speed of 25
km/h; are categorized as a “powered cycle” pursuant to the Machinery Directive 2006/42 EC.
However, the specific regulation pertaining to powered cycles, other electric bikes and VOLTs
vary from country to country. Therefore, in EU countries the various VOLTs are considered a
bicycle, electric bicycle, moped, (speed) pedelec, motorbike or another separate class of
transportation depending on the country, VOLT model and your specific configuration.
Like all other bikes, each specific transportation category demands for specific requirements
and subjects your VOLT to certain regulations depending on the specific VOLT model and its
specifications. Accordingly, the regulations pertaining to a VOLT will vary from country to country

WARNING: If you are uncertain about any of the following instructions, or unfamiliar with bicycles or
bicycle assembly, you should take your VOLT and this manual to your local bike shop and have the
assembly performed by a qualified bicycle mechanic. Failure to properly assemble your VOLT could
cause one or more parts of the bike to fail or to operate incorrectly, which could result in your injury
or death.
How to assemble the front wheel
1. Remove the fixed axle (27) by unscrewing the nut on both sides and removing the axle from the wheel.
If tight, it can be loosened with a 15mm crescent wrench.
2. Remove brake pad spacer from brake caliper, then lift the frame/fork (23) and place
the front wheel in the bike’s fork to align the axle with fork dropout slots.
3. Make sure that the disc brake (24) is well placed in the middle of the brake caliper.
4. If your bike is equipped with hydraulic brakes, be sure NOT to squeeze the brake
lever (20).
5. Insert the axle (27) all the way through.
6. Screw the nuts back onto both sides and very securely tighten the wheel using a
15mm crescent wrench. Then with a torque wrench, tighten to 28-32Nm. Be sure to also tighten the fixed
rear wheel axle nut to 30-35Nm.
If something appears to be wrongly assembled - even if you have followed the instructions, please
contact us before riding your VOLT, or take your VOLT to your local bike shop to have it checked,
WARNING: Attach the wheel securely. A loose or detached wheel can cause you to lose control of
your VOLT and fall, and could cause you serious injury.

ASSEMBLING YOUR VOLT

How to assemble the handlebar
1. Lift and straighten the handlebar (19) until it is perpendicular to the ground and lock the handlebar stem
safety locking mechanism in place.
2. Insert the loose handlebar (19) into the handlebar stem (22) with the brakes (20) facing outward, and hold
into place in the handlebar stem groove. Then place the handlebar stem top cap on top of the handlebar.
As you screw in the bolts – one on each side of the bar– be sure to leave the same exact spacing between
the handlebar stem and top cap on both sides of the handlebar. There needs to be the same amount of
handlebar showing on both sides, between the handlebar stem and top cap.
NOTE: if there is not an equal amount of space on both sides of handlebar, then the bar can come loose or
threads stripped due to one bolt not being sufficiently long enough when incorrectly installed.
3. When the handlebar is securely in place, tighten both bolts to 6-8Nm using a torque wrench. In addition,
for further safety assurance, tighten handlebar stem bolt to 13-15Nm and bar end bolts to 4-5Nm.
4. To raise or lower the handle bar to match your body shape and riding style, simply release the quick
release on the handlebar stem, raise or lower accordingly, then flip the handlebar stem quick release
securely back into place. Do not raise the bar above the limit lines printed. Doing so will risk your safety.
WARNING: Make sure that the handlebar fits tightly and securely into the handlebar stem groove
and that there is no movement when firmly pushing/ pulling on the bar. In addition, be sure to push
down on the handlebar to make sure that the handlebar stem quick release is secure. Failure to do
so could result in loss of control of your VOLT and could cause you serious injury.
13

How to assemble the saddle (seat) & seatpost
1. Remove the seatpost wrapping.
2. Loosen the seat post quick release(3).
3. Insert the seat post(2) to the desired height before securing it in place with the quick release (3).
4. For safety assurance, tighten the saddle bolt to 22Nm with a torque wrench before you ride.
WARNING: Do not slide the saddle all the way back on the rails. Specifically, be sure to leave a
minimum of 1cm spacing from the edge of the seatpost clamp to the beginning of the bend in the
saddle rails. In addition, do not raise the seatpost (2) above the “minimum insert” line clearly
printed on the backside of the seatpost (2).
14

Assembling the pedals
1. Each pedal has an “L” sticker or “R” sticker to indicate the left or right side of the VOLT - as you look at your
VOLT from behind. Otherwise, please check the external edge of the pedal body or inside of the pedal axle
where the pedal inserts into the crank arm for the imprinted “L” or “R”.
2. The left pedal is already pre-installed for you. IF you need to remove it, keep in mind that it is removed by
turning clockwise - as you look inward towards the crank-and tightened by turning counter-clockwise.
3. To install the right “ R ” pedal, carefully hand - screw it in , clockwise direction as you look inward towards
the crank. Use the largest of the allen keys(6mm) provided to tighten the pedal in place. Do this by sticking
the allen key in to the pedal via the back side of the crank arm and turning counter-clockwise. Alternatively,
you can use the 15mm crescent wrench to tighten the pedal, turning clockwise (see photo).
WARNING: If the pedal does not turn smoothly into the crank, do not force it as this can strip the
threads of the crank arm. Instead, back it ouvt and try again until it goes in smoothly. In addition, make
sure the pedals are tightly attached to each crank arm. Failure to tightly attach the pedals could
result in the pedals becoming loose while riding as well as strip the threads. A loose or detached pedal
can cause you to lose control of your VOLT and fall, and could cause you serious injury.

How to adjust frame-folding lever
If your folding-frame lever does not strongly snap into place when locked, or is not flush against the frame,
you will need to adjust the locking mechanism and/or lever-to-frame distance.
Locking mechanism
To adjust locking mechanism (perform ONLY if your frame-folding lever does not strongly snap into place
when locked or appears to come loose to allow frame to fold):
· Slide the mini knob on top of the silver frame-folding lever that releases this handle to open it. ·Once opened,
locate the very small black pin that protrudes upwards. It is close to the round silver battery-release button.
· Now that you’ve located the pin, close the frame-folding lever by pushing it back against the frame.
· Grab a small 3mm size allen key and stick it into the tiny hole on the underside of the small black pin. Turn it
clockwise. You’ll know it is the correct direction if the pin protrudes upwards.
· Keep turning until the pin reaches the lever. You’ll know you’re there when you can no longer turn the pin.
