A. Assembly Instructions
This bike should be assembled and adjusted by a professional trained bicycle mechanic
Most of the critical components on the Beach Bum eBike will come pre-assembled. This
includes the rear wheel, motor, gear system, and all cabling. The following steps are the best
practices for completing the assembly.
Note: With the exception of the pedals, all fasteners are tightened with a clockwise motion, and
loosened with a counterclockwise motion.
Required Tools For Assembly:
- M4 Hex Key/Driver
- M5 Hex Key/Driver
- M6 Hex Key/Driver
- Pedal Wrench
- Adjustable Spanner/Wrench
- Calibrated Torque Wrench
A.1: Handlebars
- Open the top of the shipping carton and carefully remove the frame.
- Remove all of the protective paper and foam packaging from the frame. Carefully cut the
zipties where necessary.
- Prop the bike up on the rear tire and front forks. Insert the handlebar post into the
headset. Make sure that the post is inserted past the minimum insertion mark (Fig.
1.1). Tighten the stem in a with a M6 hex wrench (Fig. 1.2) until the recommended level
of torque is reached. (Fig. 6.1)
Figure 1.1
Figure 1.2
- Loosen the bolt on the front of the handlebar stem
(Fig. 1.3), then rotate the handlebars towards the
cockpit until the leather handlebar grips are
parallel with the ground. Ensure that the
handlebards are still centered, then tighten the bolt
to secure the handlebar system in place.
Figure 1.3

A.2. Front Wheel
- Remove all packaging from the wheel and front fork.
- Loosen the nuts on the wheel axle, so that it can easily fit onto the fork.
- Insert the wheel into the fork so that the rotor slides into the caliper. (Fig 1.4 &1.5)
- Evenly tighten the nuts on the wheel axle to secure the front wheel.
- Lift and spin the front wheel to make sure there is no friction against the disc brake.
- Tighten the nuts until the recommended level of torque is reached. (Fig. 6.1)
Figure 1.4
Figure 1.5
A.3: Pedals
- Look over the pedals before installation; they are threaded specifically to only fit on one
side of the bike. (“L” for rider’s left, “R” for rider’s right)
- Begin the installation by twisting the pedal into the correct pedal arm by hand.
- Once the pedal becomes too difficult to twist, use a pedal wrench to tighten the bolt.
-Important: The left pedal is threaded in the opposite direction, and needs to be
tightened by twisting counterclockwise. This is standard on most bikes.
A.4: Lights
- Loosen and remove the nut, bolt and washer from the fork (right above the wheel).
- Thread the bolt through the hole on the headlight and secure with the washer and nut.
- Tighten using a wrench and a M6 hex driver to ensure a secure fit.
- There will be one loose cable hanging near the headset. Connect the light to the power
supply using this cable.(all three prongs must line up for this connection).
B. Installing / Removing the Battery
B.1: Installing the Battery
- Ensure that both the battery and dock are dry before the installation.
- Remove the battery from all packaging. (The key will be taped to the bubble wrap)
- Insert the battery into the frame from the left side to avoid the chain (with the on/off
switch facing out to the right side of the bike).
5
- Insert the battery at the top of the dock and slide it down into the locked position.
- Once the battery is in the dock, insert and turn the key to lock the battery in place.
- The key should have 180° range of motion. If the key can only turn 90°, the battery is
not correctly housed in the dock, and will need to be re-installed.
B.2: Removing the Battery
- Rotate key to unlock the battery from the dock.
- Use one hand at the bottom of the battery to lift it from the base position of the dock.
- Pull the battery out to the left of the bike frame/battery dock.
C. Saddle Position
A correctly positioned saddle will make the riding experience more comfortable, controlled and
efficient. It is important to spend time finding the correct saddle position. Tower Electric Bike
saddles can be adjusted in 3 ways:
- Height, Angle, Front/Back
C.1: Saddle Height:
- To check the saddle height, begin by sitting on the saddle.
- Place one foot on the center of a pedal and the other on the ground for stabilization.
- Rotate the pedal until it is in the lowest position (Fig 1.6).
● In this position, the leg on the pedal should be almost straight, with a slight bend
in the knee. The rider should also be able to reach the lowest part of the pedal’s
rotation comfortably, without needing to shift any weight.
Figure 1.6
6
- If the saddle height needs to be adjusted, follow these steps:
● Loosen the seat post clamp. (Fig 1.7)
● Increase or decrease the height to a comfortable position.
● Confirm that the saddle is parallel with the bike frame and the seat post is not
past its minimum insertion mark. (Fig 1.8)
● Tighten and close the seat post clamp to secure the seat in place. (Fig 1.9)
Figure 1.7
Figure 1.8
⚠ Warning: Securing the seat post with the “Minimum Insertion Mark” exposed may
cause the seat post or eBike frame to break.
Figure 1.9
C.2: Saddle Angle:
- The saddle angle can be adjusted to provide maximum comfort while riding. The majority
of cyclists prefer their saddle to be horizontal, as it arrives in the box.
- When adjusting the saddle angle, be sure to loosen the clamp sufficiently so that the
teeth in the mechanism have space to rotate. When securing the clamp, tighten it to the
recommended torque (Fig 6.1) to prevent clamp slippage while the bike is in use.
7
C.3: Front and Back Position:
- Adjusting the saddle in this manner will be down to personal preference and will often be
related to rider’s height and arm length. When tightening the front/back position, ensure
that the clamp mechanism is not on the curved part of the rail.
⚠ Warning: After making and changes to the saddle position, ensure that each clamp is
tightened to the recommended torque (Fig 6.1). Loosely fitted clamps may wear the
thread on the movable components. The threading is there to help the components stay
in place by providing resistance. Without this, it may be difficult to maintain saddle
position.
D. Start Up Procedure
⚠ Warning: Do not use this product before reviewing the safety instructions included in
Chapter 2 of this user manual.
- Insert and rotate the key to lock the battery in place.
- Remove the key and confirm that the battery is locked correctly.
- Turn the battery on by flicking the red switch to the on position (-).
- Hold down the [M] button on the LCD display for 2 seconds, to turn on the eBike and
display.
- Use the [+] and [-] buttons to select the desired pedal assistance level. Level 1 is the
lowest level of assistance and Level 5 is the highest. (Fig 6.2)
- Ride safely and have fun!

2. Safety
A. Safety Basics
⚠ Warning: It is the responsibility of the rider to know the local laws and rules of the
road. These laws may be different in each area and extend to safety equipment, lighting,
licensing, areas to ride and specific bike traffic laws.
⚠ Warning: Always wear a helmet. Having an accident while not wearing a helmet may
result in serious injury or death.
- This electric bike is designed for use by riders of age 18 and over.
- Riders should have the mental capability, reaction time and physical condition to ride
and manage themselves and this eBike in traffic and other road conditions.
- Ensure that the eBike is the correct size before riding. Control may be compromised if
the eBike is not fitted correctly.
- Perform a quick mechanical safety check before every ride. (Section 2.E)
- Tower Electric Beach Cruisers are not designed for jumping or off-road use.
- The Beach Bum is pre-governed at 18 mph. This can be adjusted in the advanced
settings. Contact Tower customer support for instructions on how to remove the speed
limit. The governor should only be removed for use on private property.
- Always ride at a comfortable speed, and obey local traffic laws.
B. Riding Safety
- When possible, ride in bike lanes or to the far right side of the street. Always ride in the
same direction as the flow of traffic.
- When riding on the street, use hand signals to indicate turns and slowing/stopping.
- Do not ride with objects that may impair vision or control of the eBike.
- Do not hitch off the back of another vehicle.
- Do not ride while under the influence of alcohol or drugs.
- Do not ride at dawn, dusk or in complete darkness without adequate lighting.
C. Wet Weather
⚠ Warning: Wet conditions are a source of many bicycle accidents. Visibility, braking
distance and traction all become impaired.
- When the road surface is wet, the stopping power of all vehicles will be reduced and all
tires will lose grip much more easily. Apply the brakes earlier and more gently in order to
avoid wheel lock and safely stop in wet conditions.
