Rider Safety Warnings

1. Before riding please read the manual carefully and check if each component is secure to ensure a safe ride. If there are any problems, please contact your nearest dealer.
2. While riding on the road, abide by all local traffic laws. In wet conditions, ride at a slower speed than normal. Do not ride with more than one rider on the e-bike.
3. Store your e-bike in dry, ventilated areas and do not submerge in water. If the e-bike is submerged deeper than the bottom bracket, it can lead to internal circuit short-outs and damage the electrical system.
4. The battery used on this e-bike is a safe power source. To avoid any risk of electrical shock to the rider, the anode and cathode of the battery cannot come into contact with wet hands and metal at the same time. This will generate a large circuit current causing injury to the user. Please exercise extreme caution around this.
5. Do not allow inexperienced riders to ride your e-bike to avoid damage to your bike or injury to the rider. Make sure they are confident riders, and you give them suitable instruction before riding.
6. Select the lowest level of assistance on the display controller before you start riding the bike.
7. Make sure your tire pressure is in the normal PSI range (indicated on the tyre sidewall) before riding.
8. Make sure the screws on each component are tight and secure before riding.
9. This e-bike’s controller has an ‘overload protection’ function. This function will automatically cut-off the power supply when the ebike’s electrical system is overloaded, and automatically resume when levels return to normal.
10. Tum off the power on the display when you finish your ride to avoid damaging the electrical system.
11. Tum off the power when you are walking the vehicle to avoid accidentally pressing the handle throttle or pushing the cranks around. This will cause your bike to start moving and can cause injury. Alternatively, you can use the ‘walk’ function (see pg 18).

E-bike Unpacking and Assembly

Unpack the bike box and carefully set aside any extra accessories.

Remove the e-bike from the box, clipping the ties from the front wheel and handlebar. Next, remove the foam padding attached to the frame.

Fore-bikes that come with mud-guards, assemble the front mud-guard and headlight using an allen key on the bolt at the top of the fork.

Next, secure the mud-guard supports using a Philips head screwdriver on the screws at the bottom of the fork.

Secure the front disc brakes with the inner six screws on the front fork disc brake mount. There are two installation methods: radial mounting and axial mounting.

Attach the front wheel by loosening the quick-release handle, inserting the wheel into the fork so the brake rotor sits in the middle of the brake pads. Finnly tighten the front wheel using the quick release handle on the front fork while keeping the front wheel centered.

Put the kickstand in the down position to keep the bike stationary. Place the knurled part of the handlebar into the stem faceplate and tighten the screws with an Allen key.

A. Make sure that the screws are all evenly tightened, and that there is an even gap on the top and the bottom of the stem faceplate.
B. Ensure that the handlebar is perfectly centred and set to the desired angle.

Grease the seat post, then insert the seat post into the seat tube, adjusting to the appropriate height. Firmly tighten your seatpost using the quick- release lever.

• A). The seat post must be placed into the frame deeper than the MINIMUM INSERT safety line indicated on the post.
• Put the pedals onto the cranks. Ensure that you have the correct left pedal going into the left crank, and vice versa. They are marked with an ‘L’ and ‘R’ accordingly. The left pedal tightens anti-clockwise, and the right pedal tightens clockwise.

E-bike Tuning Instructions

Disc brake Adjusting:

• A). Adjust the amount of space to the right and left of the disc rotor so that the rotor does not rub on the brake pads. This is done by adjusting the position of the brake on the fork/frame by loosening off the mounting bolts, making small corrections and retightening them.
• B). You can adjust the position of the right side brake pad by tightening or loosening the bolt on the side of the brake calliper.
• C). You can adjust the brake cable tension using the micro adjuster on the brake calliper or on the brake lever.
• D). Your wheel should completely stop turning when the brake lever is pulled to the halfway position.

Derailleur Tuning:
The principle of daraillaur tuning: soma a-bikes have a front and rear derailleur – soma models only have one at the rear. Forebikes with both, adjust the rear derailleur first and then adjust the front derailleur.

Tuning the rear derail/eur:

• A) Adjust the upper limit bolt with the chain in the smallest chainring at the back so that the chain cannot move past the smallest chainring.
• B) Shift the chain into the largest chainring at the back.
• C) Adjust the lower limit bolt so that the chain cannot move past the largest chain ring.

• D) Shift the chain into the smallest chainring at the back and then apply appropriate tension to the gear cable using some needle nose pliers.
• E) Fix the gear cable in place by tightening the cable clamp on the derailleur while still applying tension to the gear cable.
• F) Fine tune the cable tension until the gears shift smoothly using the micro adjuster on the derailleur.
• G) Adjust the chain tension screw so that the gears shift smoothly.

A). Display Button instructions

• B). Check that all the bicycle’s electrical connections are in normal condition before the circuit test.
• C). Hold the button for 2 seconds to switch ON the electric bike system and display.
• D). Press the button for 2 seconds to turn ON the DISPLAY BACKGROUND LIGHT (and tum on the headlight if the bike has one)
• Press the button again for 2 seconds to tum OFF the DISPLAY BACKGROUND LIGHT and headlight.
• E). If you are walking your e-bike up a hill for instance, you can enter WALK MODE by holding the button continuously. The bike will power beside you at a maximum speed of 6kmph. “P” is displayed on the screen at the same time. The walk-mode function switches off as soon as you release the button.
• F). Press change between assistance levels. Assistance Level 1 is the slowest level. The higher the number, the faster the assistance.
• G). After switching on the electric Bike system by holding the M button for 2 seconds, the display shows the Current Speed. To cycle through the different metrics, press the “MODE” button multiple times to show the following information: Running Speed (Km/h) – Trip Distance (Km) -Trip Time (Hour) – Average Speed (Km/h) – Max Speed (Km/h).
  Each state will display for 6 seconds and than automatically return to the Currant Speed screen. On the condition that the speed is 0 km/h, Trip Distance will be added to the circulation interface.

E-bike Troubleshooting – Dealers Only

To access the Boulevard settings menu, press the on. Press or to navigate, and use the and the button simultaneously for 2 seconds while the bike is button to select options.
Note : This is for authorized dealer use only. Customers are not permitted to change these settings – doing so will void the warranty and Boulevard will not take any responsibility for any incidents that occur as a result of unauthorized changes.

To check if the motor is working normally, spin the cranks with any assistance level selected (except for zero) while the bike is placed up in a work stand. The indicator light underneath the bottom bracket will light up – This means the motor is working normally. To check if the brake motor-cutout function is working correctly, hold the button (this will enter walk mode and start the motor). At the same time, squeeze the brake to confirm that the motor stops running.
