Electric trikes can be dangerous to use. The user or consumer assumes all risk of personal injuries,
damages or failures of the tricycle or system and all other losses or damages to themselves and
others and to any property arising as a result of using the tricycle.
As with all mechanical components, the tricycle is subjected to wear and high stresses. Different
materials and components may react to wear or stress fatigue in different ways. If the design life
of a component had been exceeded, it may suddenly fail possibly causing injuries to the rider. Any
form of crack, scratches or change of colouring in highly stressed areas indicate that the life of the
component has been reached and it should be replaced.
For replacement parts, technical information and warranty assistance,
please contact Jorvik Tricycles on 01904 848988 or email [email protected]
Warning
DO NOT DISASSEMBLE, MODIFY OR REPLACE ANY OF THE ELECTRICAL PARTS.
Your insurance policies may not provide coverage for accidents involving the use of the electric
tricycle. To determine if coverage is provided, you should contact your company or agent.

Assembly Instructions
Your trike has been pre-assembled. It requires only a few simple steps to get
it ready for your rst ride.
1. Remove the outside carton after cutting the nylon bands and taking off
the lid. Carefully remove your trike from the box and gently rest it in place.
2. Remove all of the inside cardboard protection and bubble wrap.
3. Locate and set aside the kit box containing the battery charger, pedals,
this user’s manual, and tool kit.
4. Install the front wheel by lining up the disc brake and place the fork of
the trike onto the front wheel.

5. Insert the quick release skewer & turn the skewer adjusting nut
clockwise to tighten it. Keep turning the adjusting nut until you see or
feel the nut contact the face of the dropout.
6. Next, try closing the lever. Your goal is to tighten the adjusting nut
enough so that the lever can be fully closed and closing it requires
signicant force. You want it to be hard to close, you want to see a
lever mark on your hand. If the lever is not hard to close, hold the lever
and further tighten the adjusting nut, try again. If not possible to close
or its very, very hard to close, hold the lever and slightly loosen the
adjusting nut, try again. Towards the end of the adjustment process,
quite small changes, like ½ turn, of the adjusting nut are necessary.
Your goal is to tighten the adjusting nut enough so that the lever can be
closed but requires signicant force to close. You want it to be hard to
close, you want to see a mark on your hand.
7. Also, be sure the movement of the lever isn’t restricted by contact with
the fork.
8. All wheels may need to be trued using a spoke key.

Disc Brakes
Your Jorvik trike is equipped with disc brakes for maximum reliability. Applying hand pressure to the brake levers will
engage the brake pads against the brake rotor, creating friction and slowing down the wheel. The more hand pressure
applied to the brake lever, the faster the trike will come to a stop.
The rear brake should always be applied before and while the front brake is applied. Applying only the front brake to slow
or stop at high speeds may result in the rider being ejected from the saddle and continuing forward over the handlebars.
It is best to apply even pressure to both brake levers when slowing or stopping.
Tricycles equipped with disc brakes will occasionally make a slight scraping noise when the wheels are turning without
the brakes being applied. This is normal.
How To Assemble This Tricycle
WARNING:
Disc brake rotors become hot during use. Do not touch or come in contact with the disc rotor shortly after use.
Wet weather will require a longer distance to stop. Brake earlier and avoid sudden stops when riding in wet conditions.

Assembly Instructions
Make sure that the brake lever does not contact the
handlebar when full hand pressure is applied. The contact
point should feel rm and solid. If the lever travels all the
way to the handlebar or feels spongy, they may require
service by a qualied bicycle technician.
If the brakes are still not operating correctly, they may
require further adjustment by an experienced bicycle
mechanic.
New Brakes Bed-in Procedure
New brakes will require a “bed-in” procedure prior to
your rst ride, which will ensure the most consistent and
powerful braking feel.
1. Find a safe riding area that will allow for moderate
speed. Remain seated during the entire procedure for
optimal results.
2. Accelerate the trike to a moderate speed, then rmly
squeeze the brake levers until you are at walking
speed. Repeat this process about twenty times.
3. Accelerate the trike to a faster speed, then rmly
squeeze the brake levers until you are at walking
speed. Repeat this process about ten times.
IMPORTANT NOTE:
Do not lock up the wheels at any point during the bed-in
procedure.

Front Fender And Light Assembly
Please attach the new easy t front fender using the bolt already located at the rear of the forks or in the hardware box,
also attach the front light using the same bolt/bracket as shown in the images. (There is now no need for the fender
support bars.)

The Seat
Make sure that the seat is tight enough so that you can’t twist it out of alignment. Pull the seat clamp handle away from
the seat post and slide the seat up to down to adjust it. Move the clamp handle inward toward the seat post so it is held
tight by the clamp.
This should require a fair amount of force to ensure the seat post is held tight.
Turning the bolt clockwise will increase the clamping force and counter clockwise will decrease the clamping force.
Make sure the seat is not set with the vertical maximum height marks above the clamp.

Please Note: The pedals are marked “L” for Left and
“R” for right. The left pedal is attached by turning it
counterclockwise and the right pedals are tightened by
turning them clockwise. Make sure the pedals are tightly
attached to the crank arms to prevent slipping.

Front Suspension Travel And Sag Guide
Sag is a measurement of the amount of suspension
fork travel with the rider stationery in their normal riding
position. The Sag depends on the position and weight
of the rider and should be between 15% and 30% of the
fork’s max travel depending on the intended use and
preferences.

Gears
Your Jorvik JMT model trike is equipped with 7 speed nexus hub gear driven system. The rst gear is for easier and uphill
pedalling, and the last gear is for maximum speed on level or downhill terrain. Change gears only while pedalling. When
the grip shift nexus gear selector shows ‘1’ you are in the rst gear, or the lowest gear. When it displays ‘7’ you are in the
highest gear. Adjustments require the ne tuning and should only be made by a qualied technician.
Avoid changing gears very rapidly from rst gear to the last gear or vice versa.

How To Assemble This Tricycle
The keys are used to lock the battery into place. Always
make sure that the key position is in the “unlock” position
when removing or inserting the battery. Move the key to
the “on” position to secure the battery before operating the
trike. Riding the trike with the key is in the “unlock” position
risks allowing the battery to slide out and damage the
battery when dropped. Always remove the battery from
the trike when transporting on a trike rack.
After receiving your E-trike, please keep the keys
separately, in case of losing both keys, Jorvik tricycles Ltd
is not able to deliver replacements.
Appearance Care And Maintenance
Periodically clean your Jorvik tricycle electric trike with a
damp cloth. Avoid spraying the bike with a water hose to
avoid electrical issues. Store your bike in a dry shelter area
away from direct sunlight and wet or damp environments.
It is also recommended to apply chain lube to the
drivetrain of your trike when you clean it or wipe it down to
keep it in good running condition.
Monthly, clean your drivetrain and inspect chain for wear;
re-apply lubricant to the chain and wipe off any excess
with a cloth. Check wheels for loose spokes; tighten if
necessary. Check the tightness of stationery and moving
parts, such as, the crank arms and pedals, stem bolts, axle
nuts, etc. Inspect your braking system, both levers and
callipers to ensure safety while riding. Replace damaged
or worn parts, such as, cables and brake pads
Battery Fuse
The fuse is designed to protect the battery. If the fuse
blows, there will be no power to any of the electrical
components powered by the battery.
You can email Jorvik Tricycles for further advice if required.

Tyres And Inner Tubes
Use a reliable tyre air pressure gauge to check for ination
before every ride. At the same time, inspect tyres for
excessive wear and cracks. Replace tyres if necessary.

When the pedal assist mode so set to “0”, the pedal assist
function(s) do not engage. The throttle control will still
work.
The throttle control is operated on the left-hand side.
You control the throttle by pushing it using your thumb, the
more you press the more power is released. The further
the throttle switch is from its resting position; the more
power is delivered to the motors to accelerate the Jorvik
JMT trike.
When you want to slow down, you simply release
the throttle and let it return to its resting position and
simultaneously apply the brakes.

Charger
Included with your new Jorvik Trike is a lithium ion battery,
along with a charger, which plugs into a standard
household electric outlet.
A lithium ion battery requires specially designed chargers.
You should never charge your battery with a substitute
charger that is not designed for this use. Use of an
unsuitable charge to charge a lithium ion battery could
result in over-heating, re, or even explosion.
Recharging The Battery
The Jorvik battery may be charged while on the trike or
removed and charged at a location away from the E-trike.
The battery is easily removed by turning the key to the
unlock position, grasping the handle of the battery, and
sliding the battery out.
To charge the battery, plug the charger in to an AC outlet.
Then plug the charger in to the charging port located on
the bottom or side of the battery by opening the rubber
charger cover. The LED indication light on the charger
should be green and turn red once plugged into the
battery and charging. It will then return to green again
once fully charged.
