To ensure your safety, please perform the following checks frequently before operation:
- Turn the power switch (located just under the seat) on and check to see if the bike turns on
properly. Lightly turn the throttle to see if the motor is functional. Since the motor is in the
rear wheel, it may be difficult to do a “lift-test.”
- Is the air of the tire normal?
- Are all major screws locked tightly?
- Is the battery charged?
- Are the brakes fully functional? (So that it stops the rotating wheel with comfort)
- Are the handle bars and seat adjusted properly? (And properly tightened)
Battery and Charger
- Only use the battery charger that came with your bike; it designed specifically for your bike
and its battery. Using a charger that was not designed for the New Yorker can cause severe
damage to battery and could potentially become a fire hazard.
- Do not store the batteries in an excessively hot or cold environment for a long period of
time.
- When you are done charging, unplug the charger from the outlet and from the charging port
of the bike.
- Keep your bike charged, whether you are using it or not.
- Please keep the charger out of the reach of children.
- Charge your bike according to how often you use it. The more often you use it, the more you
should charge the bike.
- When charging the bike, please ensure that the power is turned off (and remove the key).
- On the charger, a red light will indicate that power is being supplied to the charger. A green
and red light will be on to indicate that the battery (of the bike) is being charged. The green
light will turn off (leaving the red one on) to indicate that your battery is completely
charged.
- The charging port is on the battery just hidden by the fold-down handle (at the top of the
battery)
- If you notice that the green light has not turned off for a long period of time (8 hours or
more), then please check the following:
o Is the plug to the charging port properly inserted?
o Is the plug to the outlet properly inserted?
o Are the batteries damaged?
o Is the charger damaged?
o Turn on the bike and slowly turning the throttle, does the motor start?
o Bring the bike back to a Daymak store (or your dealer) to get it checked out.
- The battery can be charged in two ways:
o (1) Plugging the charger in to the charging port on the bike
o (2) Removing the battery from the bike and charging the battery directly

General Information
- Before you use your bike, please ensure that the battery is properly installed and that the
battery is connected. You can tell it is connected once battery is locked into place. You can
find the lock at the bottom of the battery, on the actual frame of the bike.
- When taking off from neutral position (and on steep hills), it is advisable that you begin by
pedaling. Since the bike has “power assist,” the bike’s motor will automatically initiate once
you pedal. Doing so will allow you to conserve battery and will ultimately get you more
kilometers between charges.
- Top speed and distance will vary depending on the weight of the rider and the terrain. The
New Yorker (like a normal bicycle) is meant for level, paved surfaces and roads. Please
refrain from riding your bike in mud, snow, over potholes and curbs.
- Do not attempt stunts, jumps, or tricks with your electric bicycle.
- Always wear an approved safety helmet.
- Always be aware of local and road laws to ensure maximum safety.
- Make sure the kickstand has been disengaged before operating the bike.
o The kickstand has a locking mechanism which should be depressed before you can
- The New Yorker is a foldable bike.
o There is a pin in the center of the bike’s frame (directly below the seat) that seems

Once loosened enough, you will be able to fold the handlebars as well.
Maintenance
- Check air pressure in the tires. The optimum PSI is 44.
- Check all nuts and bolts as they can loosen from vibration due to usage. Some examples are:
- Check the brakes for adjustment and make sure that they are fully functional at a
