Safe Cycling and Safety Tips

Pre-Ride Check Points

Before you ride your pedal electric assistance bicycle always make sure it is in a safe operating condition. Particularly check that your:

• Nuts, bolts, quick-release and parts are fastened tight, not worn, or damaged.
• Riding position is comfortable and unencumbered.
• Brakes are operating effectively.
• Steering is free with no excessive play.
• Wheels run true and hub bearings are correctly adjusted.
• Wheels are properly secured and locked to frame/fork.
• Tires are in good condition and inflated to correct pressure (tire pressure in on tire sidewall - do not exceed max tire pressure).
• Pedals are securely tightened to pedal cranks.
• All reflectors are in position and secure.

After you have made any adjustment to your electric bicycle, check that all nuts and bolts are securely tightened and cables are free from kinks and fixed securely to the electric bicycle frame. Every six months, your electric bicycle should be professionally checked to ensure that it is in correct and safe working order. It is the responsibility of the rider to ensure all parts are in working order prior to riding this electric bicycle.

What Never To Do When Riding

NEVER ride without wearing an approved helmet, which must meet USA/ European (CPSC/EN) standards. Always comply with the local laws and ordinances.

• NEVER ride on the same side of the road as oncoming traffic.
• NEVER carry a passenger, this bicycle is designed for a single rider only.
• NEVER hang item(s) over the handlebars, this could interfere with steering or catch in the front wheel causing a crash.
• NEVER hold on to another motor vehicle or bicycle.
• NEVER ride too close to another vehicle - keep your distance and awareness.

Wet Weather Riding: Your bike's brakes do not work as well under wet or icy conditions as they do under dry conditions. The braking distance in wet weather will be longer than that in dry conditions. Take special precautions in wet weather to assure safe stopping. Ride slower than normal and apply your brakes well in advance of anticipated stops.

Night Riding: Do not ride at night. If you have to be on your e-bike at night or in low-light conditions, always comply with laws and regulations (local and otherwise) for bicycle lighting. Use approved headlights (white), taillights (red) properly affixed to your e-bike in addition to all-around reflectors. For additional safety, wear light colored clothing with reflective stripes, or safety yellow or safety orange clothing. Check that the reflectors are firmly secured in the correct position and clean and not obscured. Damaged reflectors must be replaced immediately.

Routine Maintenance Check and Lubrication

As with all mechanical components, your bicycle is subjected to wear and stress. Different materials and components may react to wear or fatigue in different ways. If the design life of a component has been exceeded it may suddenly fail, possibly causing injuries to the rider. Any types of cracks, scratches, or change of coloring in highly stressed areas indicate that the life of the component has been reached and it should be replaced immediately.
Always inspect your bicycle before every ride.

Use only genuine replacement parts, particularly for safety-critical components, installed by a professional bicycle mechanic. To keep your electric bicycle functioning well, the following routine maintenance lubrication is necessary (refer to Fig. 2):

Assembly Instructions

Following is important information and instructions for assembling and maintaining your new electric bicycle.

Step 1: Unpacking Your Bike

1. Remove your e-bike from the box.
2. Watch-out for staples and sharp edges as you lift the bike out of the box. A friend can make this easier. Do not lay flat and cut-out the bike from the box - you may damage the bike.
3. Cut all of the packing zip ties. Detach all parts that are tied to the frame. Be careful not to cut/scratch the bike, particularly the tires and cables when removing the ties.
4. Do not attempt to rotate the handlebar/ fork until you are sure all zip ties and packing have been removed, otherwise you may damage the bicycle. Carefully examine the carton for loose parts and make certain that no parts are remaining in the box.
5. Rotate the handlebars (and fork) to face forward.
6. Examine your new bike for any visible damage which may have occurred during shipping.

Step 2: Front Wheel & Front Fender Installation

1. Installing the Front Wheel
   1. Remove the plastic dropout protector from the metal shipping axle. (Fig. 3)
      
      Fig. 3
   2. Unscrew and remove the metal shipping axle from the fork dropouts. use photo attached. You can discard or save this device in case you ship or transport your bike with the front wheel removed. Suggest you inflate the tire to make centering the wheel in the fork easier (point 4 below).
   3. Loosen the axle nuts on the front wheel. Lift the front of the bike and insert the front wheel into the fork dropouts (a helper can make this easier). Insert the tab of the safety washers into the small holes on the outside of the fork dropouts. (Fig. 4)
      
      Fig. 4
   4. Inspect the wheel to make sure it is centered in the fork. Tighten each axle nut a little at a time (15mm or adjustable wrench), alternating between sides, until each axle nut is properly tightened.
2. Installing the Front Fender
   1. Locate the long bolt, washer, and nut which will either be in the parts bag/box or inserted in the top of the fork.
   2. Slide the fender in place from the back of the fork. Insert the long bolt through the top/center fork hole from the front of the bike. At the rear of the fork hole, place the bolt through the fender mounting tab with the washer and nut. While pushing the fender tab up as far as it will go, tighten the bolt and nut to secure the fender to the top of the fork (Fig. 5)
      
      Fig. 5
   3. Position the fender braces to the mounting holes on the fork dropouts. It's okay to squeeze inward as these braces are designed to be pliable. Partially thread the screw through the fender brace end hole and into the dropout repeat for the other side. When both braces are partially attached, tighten the brace screws to complete the install (Fig. 5)
   4. If the fender is not straight, or rubbing the tire, that's okay! As mentioned above, the fender braces can be bent to center the fender. Gently adjust the fender by hand until it's straight.

NOTE: Rear Fender Adjustment: The rear fender is installed at the factory and should be good-to-go. However, it may require some small adjustment due to shipping. Follow "Installing the Front Fender" step 4 to straighten as necessary or a combination of loosening the brace end bolts, retightening, and centering.

Step 3: Seat Assembly

Refer to Fig. 6:

Fig. 6

1. Installing the Front Light
   1. The light holder is assembled on the bike by the factory.
   2. Take out the front light from the box and check if it is in good condition.
   3. Connect the front light with the light holder with one nuts on each side, tighten each nut properly with 5mm hex key.
2. Connecting the Electric Cable of the Light
   All the electric cables are ready, after "Installing the Front Light", connect the electric cable of the light with the other part, which is left alone, two arrows lined up. (Fig. 7)
   
   Fig. 7
3. Check the Light Function
   Open the electric system to check the function of the front light. Press the button on/ off of the display to control the light. Find more information on electrical components operation.

Step 4: Handlebar Assembly

Your Valen handlebars are installed from the factory. They are in a fixed position and not adjustable.
Please check they are tight and secure before riding.

Step 5: Installing Pedals

Refer to Fig. 8:

Fig. 8

The pedals are marked with either a "R"(Right) or "L" (Left) on the threaded end of the pedal axle.

Screw the pedal marked by" R" into the right side of the crank assembly (chain side of bicycle). Turn the pedal (by hand) in the clockwise direction. Tighten securely with a 15mm open-end, 15mm pedal specific wrench, or adjustable wrench (tighten to torque: 34N.m or 26 lbs). se

Screw the pedal marked by "L" into the left side of the crank assembly. Turn the left pedal (by hand) in the counterclockwise direction. Tighten securely with a 15mm opened, 15mm pedal specific wrench, or adjustable wrench (tighten to torque: 34N.m or 26 lbs).

Installing Rear Pedal Plates

Refer to Fig. 9:

Fig. 9

The rear pedal plates need to be installed on the chain stay by two bolts on each side, tighten securely. These pedal plates can be folded.

Step 6: Brake Adjustments

The brakes on your bicycle should be correctly adjusted from the factory. However, as cables do seat and stretch. It is important to check the function of your brakes after your first ride. Most brakes will need some adjustment after being used a few times.

Basic Disc Brake Adjustment
The following instructions are not exhaustive. We strongly suggest you take your bike to your place of purchase, professional bike shop, or certified ebike mechanic for assembly, adjustment, and maintenance.

1. Brake Lever and and Brake Pad Travel Adjustment
   You can adjust the amount of braking leverage by adjusting the brake lever travel and by the closeness of the brake pads to the brake disc.

Brake Lever/Cable Adjustment: To adjust the travel of the brake lever, loosen the Locking Collar A1 (away from lever body), turn/unscrew the Adjusting Barrel A2 (what the cable enters) left/counterclockwise which tightens cable tension and increase lever travel & leverage, this will bring the caliper brake pads closer to the disc (Fig. 10).

Fig. 10

If the pads are rubbing against the disc, reverse the process. If you have tuned the Adjusting Barrel to its maximum and the lever travel is still excessive you will have to adjust the space between the pads and the disc. Tighten the Locking Collar up to the lever body. Additional adjustments at the caliper (Fig. 11).

Fig. 11

Caliper Adjustment: Insert a hex key into the smaller hole inside hex key hole B (Fig.11). Rotating the allen key clockwise/right pushes the outer brake pad forward by approx.0.8mm. After each turn, check the braking function, so the pads are close, but do not rub the disc.

Once the correct amount of travel has been reached, centre the brake Caliper on the disc by adjusting screw C (Fig. 12).

Fig. 12

When the brake pads are centered on the disc the wheel should spin freely with no rubbing. Upon applying the brake(s), there may be a slight amount of noise until the pads "bed" in, this should stop after your first ride. Make sure there is no oil or grease on your hands or on the disc which can degrade brake performance.

2. Checking Brake Pad Wear, Pad Replacement
   Pads that are 1 mm thick (or less) need immediate replacement (Fig. 13).
   
   Fig. 13

To install new pads, remove the brake caliper from the fork or frame by unscrewing

hex bolts D (Fig. 14).

Fig. 14

Unscrew (left/counterclockwise), the smaller hex bolt inside allen bolt B (Fig.14). Lift up and pull the inner pad downward, using the protruding tab. Slide a thin slot screwdriver under the outer pad and lift it up. Hold the screwdriver in this position and remove the pad with a pair of long- nosed pliers.

Remove the springs from the worn-out pads and fit them onto the new pads. Replace the new pads, keeping them slightly inclined into the seat of the Caliper.

Check that the spring hooks correctly onto the small piston. (When pulling downwards the pads should not come out). Refit the Caliper to the fork (or frame for rear brake).

Turn adjuster screw C (Fig.12) until the pads are centered on the disc and the wheel spins freely. Again, there may be some noise from the brake until it "bed" in. You may have to adjust the cable tension and lever adjustment - follow previous Step A. Brake Lever and and Brake Pad Travel Adjustment.

We strongly advise you have your brakes periodically checked and maintained by your dealer or a professional bicycle mechanic.

Step 7: Derailleur Gears Maintenance and Adjustment

The gears/derailleur(s) on your bicycle should be correctly adjusted from the factory. However, as cables do seat and stretch. It is important to check the function of your shifting after your first ride. It is not unusual for your shifting system to need some adjustment after being used a few times.

We strongly recommend you have your e-bike serviced by your dealer or professional bike shop/mechanic.

To ensure long life and efficiency for your drive train system, it must be kept clean and properly lubricated. Before attempting any adjustments, make sure you understand the drive train components functions and feel confident to attempt such maintenance.

• Left shifter controls the front derailleur and chain wheel(s); Right shifter controls the rear derailleur and rear cogset.
• The largest/ larger rear sprockets on the cogset are the low [speed] gears used for hill climbing and low speed technical riding; the smallest/smaller rear cogs are for cruising and high(er) speed and downhill riding.
• For maximum efficiency, best riding experience, and long life, avoid using "crossover" gears, for example: the large front chainring with the large rear cog, OR or the small front chainring with small rear cog.

NOTE: For good shifting and riding experience, follow these 4 actions:

1. Shift only when pedaling (forward), do not shift when stopped.
2. Do not use hard, aggressive pedal pressure while changing gears.
3. Never back pedal when changing gears.
4. Never force the gear shifting levers.

Rear Derailleur Adjustment:
There are two limit adjustment screws on the rear derailleur - High/ "H" and Low L. Looking from the rear of the bike forward, the limit adjustments center the chain on the high/ large and low/small rear cogs which prevents the chain from going over the large cog and into the wheel/left (the "H" or high adjustment screw) or into the frame/ right (the "L" or low adjustment screw).

First, the derailleur cable tension needs to be correct:
Position the shifter(s) so the chain is on the smallest rear cog and largest front sprocket check for cable slack at point "B" (Refer to Fig. 15):

Fig. 15

If there is slack, loosen the cablenut or hex bolt, pull the cable with pliers and retighten the cable nut/bolt while pulling cable taut (tightening torque: 5-7N.m or 4-5 lbs)

High/ Large Cog ("H") Limit Adjustment
Turn the "high limit" adjust screw marked "H" on the rear derailleur so that, again looking from the rear, the upper guide pulley is below the vertical plane of the center of the top/ large cog.

Low/Small Rear Cog ("L") Limit Adjustment
Turn the "low limit" adjust screw marked "L" on the rear derailleur so that, again looking from the rear, the upper guide pulley is below the vertical plane of the center of the low/small cog.

1. Operate the shift lever to shift the chain from top gear to 2nd gear.
   • If the chain will not move to the 2nd gear, turn the cable adjusting barrel on the rear derailleur to increase the tension (counterclockwise)
   • If the chain moves past the 2nd gear, decrease the tension (clockwise)
2. Next, with the chain on the 2nd gear, increase the inner cable tension while turning the crank forward. Stop turning the cable adjusting barrel just before the chain make noise against the 3rd gear. This completes the adjustment.

Make sure the drivetrain is clean. We suggest "dry" lubricants for most applications.

Step 8: Check Before Riding

Make sure the wheels are tight and secure. Tighten the front and rear hubs nuts securely. (Tighten torque: about 30N.m for front wheel, about 25 ot 30 N.m for rear wheel).

For Quick-Release (QR) hubs/axles, make sure the QR levers are in the locked/closed position. Before riding, lift the front of the bicycle so that the front wheel is off the ground, lightly bounce it to the ground and give the top of the tire a few downward strikes. The wheel should not wobble or come off and there should be no rattling. Do the same for the rear wheel.

Electrical Components Operation, Maintenance, & Safety

The e-bike in this manual features "Start Aid". This electric assistance system will help riders save their energy when starting the bike rolling.

How Start Aid Works: When pressing the Start Aid button, the bike can be started at a speed of -3.5MPH (6km/h). When the bike starts moving forward, start to pedal and release the "Start Aid" button.

Important Safety Precautions

• We strongly advise wearing an approved helmet which meets local safety standards.
• Obey local traffic rules when riding on public roads.
• Be aware of traffic conditions.
• The rider must be over 14 years old.
• Have your bike serviced only by authorized bicycle shops.
• Regular servicing will ensure a better performance and a safe riding experience.
• Do not exceed more than 2201bs (100kgs) on bicycle, including the rider and cargo.
• Never have more than one rider on the bicycle.
• Follow the regular maintenance schedule in this owner's manual.
• Do not open or attempt maintenance on any electrical components yourself.
• Contact your local bicycle specialist for qualified service when needed.
• Never jump, race, perform stunts, or abuse your bicycle.

Using and Maintaining the Electric Hub Motor

Retrospec intelligent e-bikes are programmed to start with the electric assistance ("Start-Aid") after a rotation of the pedals (crankset).

• Do not use this bike in flood waters, heavy rain.
• Do not immerse, submerge the electric parts in water - damage will likely happen.
• Avoid impacts to the hub motor, the aluminum alloy hub cover may break.
• Regularly check the screws on both sides of the hub motor; tighten them as necessary even if they are only a bit loose.
• It is necessary to periodically check the cable connection to the motor.

Maintaining the Controller

Retrospec e-bikes have the Controller (the e-bike "brain"), positioned at the bottom and inside the battery pack holder/ housing. The Controller is a critical component for your e-bike system. It is very important to follow the care guidelines below:

Do not immerse, submerge the electric parts in water - damage will likely happen.

NOTE: If you think water may have got into the control box, switch-off the power immediately and pedal without electric assistance. You can pedal with electric assistance as soon as the controller has dried out.

As with the battery, hub, display and other electrical parts - Never strongly shake, slam/drop, or throw the Controller - damage is likely.

As with the battery, the best operating temperatures for the controller is: 5F-104F (-15ºC to +40ºC).

The controller should be used in normal working temperature range from -15ºC to +40ºC

NEVER open the controller box. Any attempt to open the controller box, modify or adjust the controller will void the warranty. Please ask your local dealer or authorized service specialist to repair your bike.

Maintaining the Power-Off Control of the Brake Lever

This is a very important component for safe riding. Pay close attention to protect it from impact and damage. Regularly check that it is securely fastened to the handlebar.

Maintaining the Throttle Lever

Take care to protect the throttle from impact or damage. If your bikes falls or you are in a crash, make sure to check the throttle function before riding. Periodically check that the throttle cable is securely plugged-in to the throttle body. If not, check and plug it in again.

Simple Troubleshooting

The information below is for diagnosing problems only. It is not a recommendation for the user to carry-out repairs. Any remedy outlined must be carried out by a professional e-bike repair person who is educated on the safety issues with bikes & e-bikes.
