Setup (Assembly)
Your MBM Boulevard bike may require some assembly upon arrival. Follow these steps carefully. It is recommended to have this assembly performed by a qualified bicycle mechanic if you are unsure.
- Unpacking: Carefully remove the bicycle and all components from the packaging. Retain packaging for potential returns or future transport.
- Handlebar Installation: Insert the handlebar stem into the fork steerer tube. Ensure the handlebar is centered and aligned with the front wheel, then tighten the stem bolt securely.
- Front Wheel Installation: If not pre-installed, attach the front wheel to the fork dropouts. Ensure the wheel is centered and the quick-release or axle nuts are tightened firmly.
- Pedal Installation: Identify the left (L) and right (R) pedals. The right pedal threads clockwise, and the left pedal threads counter-clockwise. Apply a small amount of grease to the threads and tighten them securely with a pedal wrench.
- Seat Post and Saddle: Insert the seat post into the frame's seat tube. Adjust the saddle height to a comfortable riding position where your leg is slightly bent at the knee when the pedal is at its lowest point. Tighten the seat post clamp securely.
- Brake Adjustment: Check that both front and rear brakes engage properly and provide adequate stopping power. Adjust cable tension if necessary.
- Gear Adjustment: Verify that all 6 gears shift smoothly and without hesitation. Fine-tune the derailleur if needed.
- Tire Inflation: Inflate tires to the recommended pressure indicated on the tire sidewall.
Operating Instructions
Riding Your Bicycle:
- Starting: Mount the bike, place one foot on a pedal, push off with the other foot, and begin pedaling.
- Steering: Use the handlebars to steer. Lean gently into turns.
- Braking: Apply both front and rear brakes simultaneously and smoothly. Avoid sudden, hard braking, especially with the front brake, to prevent skidding or losing control.
- Shifting Gears: Your bike is equipped with a 6-speed Revo shifter. To shift, twist the grip shifter on the handlebar. Shift to a lower gear for climbing hills and a higher gear for flat terrain or descents. Shift gears smoothly while pedaling.
Maintenance
Regular maintenance ensures the safety and extends the lifespan of your bicycle.
Daily Checks (Before Each Ride):
- Tires: Check tire pressure and for any cuts or punctures.
- Brakes: Ensure brake levers are firm and brakes engage effectively.
- Quick Releases/Bolts: Verify all quick releases and bolts (wheels, seat post, handlebars) are tight.
Weekly/Bi-Weekly Checks:
- Chain: Clean and lubricate the chain.
- Gears: Check for smooth shifting. Adjust if necessary.
- Brake Pads: Inspect brake pads for wear. Replace if worn.
- Bolts: Check all major bolts (crank, stem, seat post) for tightness.
Cleaning:
Clean your bike regularly with mild soap and water. Avoid high-pressure washers, which can force water into bearings. Dry thoroughly and re-lubricate the chain.
Troubleshooting
| Problem | Possible Cause | Solution |
|---|---|---|
| Flat Tire | Puncture, low pressure, valve issue | Inspect tire for punctures, repair or replace inner tube, inflate to correct pressure. |
| Gears not shifting smoothly | Cable tension, dirty chain, bent derailleur hanger | Adjust shifter cable tension, clean and lubricate chain, check derailleur alignment. |
| Brakes feel spongy or weak | Loose cable, worn pads, air in hydraulic system (if applicable) | Tighten brake cable, replace worn brake pads, bleed hydraulic brakes (professional service recommended). |
| Squeaking/Grinding Noises | Dry chain, loose components, brake rub | Lubricate chain, check and tighten all bolts, adjust brake calipers to prevent rubbing. |
