Pre-ride safety checklist
Safety Check Basic Steps
1. Brakes
Ensure front and rear brakes work properly.
Check brake pads for wear and ensure they are not overworn.
Ensure brake pads are correctly positioned in relation to the rims.
Ensure brake cables are lubricated, correctly adjusted, and display no obvious wear.
Ensure brake levers are lubricated and tightly secured to the handlebar.
Test that the brake levers are firm and that the brake, motor cutoff functions, and the brake light
are functioning properly.
2. Wheels and Tires
Ensure tires are inflated within the recommended limits posted on the tire sidewalls and hold air.
Ensure tires have good tread, have no bulges or excessive wear, and are free from any other
damage. Ensure rims run true and have no obvious wobbles, dents, or kinks.
Ensure all wheel spokes are tight and not broken.
Check axle nuts and front wheel quick release to ensure they are tight. Ensure the locking lever on
the quick release skewer is correctly tensioned, fully closed, and secured.
3. Steering
Ensure the handlebar and stem are correctly adjusted, tightened, and allow proper steering.
Perform a handlebar twist test (see assembly step 4) to ensure the stem riser clamp bolt security.
Ensure the handlebar is set correctly in relation to the fork and the direction of travel.
4. Chain
Ensure the chain is clean, oiled, and runs smoothly.
Extra care is required in wet, salty/otherwise corrosive, or dusty conditions.
5. Bearings
Ensure all bearings are lubricated, run freely, and display no excess movement, grinding, or
rattling. Check headset, wheel bearings, pedal bearings, and bottom bracket bearings.
6. Cranks and Pedals
Ensure pedals are securely tightened to the cranks.
Ensure the cranks are securely tightened and are not bent.
7. Derailleur and
Mechanical Cables
Check that the derailleur is adjusted and functioning properly.
Ensure shifter and brake levers are attached to the handlebar securely. Ensure all shifter and
brake cables are properly lubricated.
Notice: Before every ride, and after every 25-45 miles (40-72 km), we advise following the pre-ride safety checklist.
