Perform the following inspections and maintenance when indicated.
CHECK TIGHTNESS
Your new eBike left the shop with bolts and connections properly tightened — but those bolts and
connections loosen over time, and sometimes even during shipping. This is normal. It's important to check
and adjust them to make certain they are tight.
KNOW YOUR TORQUE SPECS
Torque is a measure of the tightness of a screw or bolt. Too much torque can stretch, deform, or break
a bolt (or the part it attaches). Too little torque can allow the part to move and may lead to fatigue and
breakage of the bolt (or the attached part). A torque wrench is the only reliable method of determining
correct tightness. If you do not have a torque wrench, you cannot properly inspect for tightness and
should consult your bike shop. The torque specification is often written on or near the bolt or part. If a
part does not have a specification on it, ask your local bike shop or contact the Bakcou customer service
department. It shouldn't take more than a few minutes to check the following and adjust as necessary to
proper torque specs:
»
Saddle clamp bolt(s)
»
Seatpost clamp bolt
»
Stem bolts
»
Shift lever attachment bolts
HANDLEBAR
Check that the handlebar grips are secure (they shouldn't move or rotate).
WARNING:
A handlebar end that is not plugged or covered can cut the rider in a crash. Inspect regularly.
FRAME AND FORK
Examine your frame and fork, especially near junctions, and clamping or attachment areas. Look and feel
for signs of fatigue: dents, cracks, scratches, deformation, discoloration, unusual noises (e.g. chain slap or
brake rub during acceleration). If you find any, contact your bike shop before riding the eBike.
BRAKES
1. Check the brake pads for wear.
2. On the disc brakes, replace brake pads that are thinner than 1mm.
3. Check the thickness/wear of the rotors.
4. The minimum thickness is often printed on the disc.

WHEELS AND TIRES
Check the tires for damage or a worn area. As a tire wears thin, it may become more susceptible to
puncture. If a cut goes all the way through the casing, or any casing thread shows through the tread,
replace the tire. Your bike shop should fix or replace loose spokes or spokes with damage.
FENDERS
When re-installing a fender, make sure you use the bolt(s) supplied with the eBike or fender assembly.
These bolts have specific sizes and locking capabilities. Failure to use these bolts may result in a loose or
detached fender contacting the tire causing an abrupt stop.
DERAILLEURS
Shift gears through all the sprocket combinations to make sure the derailleurs operate correctly and
smoothly, and the chain does not come off.
PEDALS
1. Wiggle the pedals to make sure they're secure on the crank arms.
2. Rotate the pedals on the crank arm. If the pedals don't rotate smoothly, see your bike shop to adjust
your pedal bearings.
3. If necessary, tighten your pedals. The right pedal is threaded in the usual direction.
The left pedal is left-hand threaded.
CHAIN
1. Check the chain for stiff link pins or wear and dirt.
2. Clean and lubricate the chain.
CABLES
1. Check the cables for problems: kinks, rust, broken
strands, or a frayed end. Cables should have an
end cap to prevent fraying.
2. Also check the cable housing for loose wire
strands, bent ends, cuts, and worn areas. If there
is a problem with a cable or housing, do not ride
your eBike. Unless you feel comfortable adjusting
your wire cables, take your eBike to your bike shop
for service.
ACCESSORIES
Check all accessories to make sure they're correctly
and securely attached.
