1.3 Before Every Ride.
Your bicycle has undergone numerous tests during production and a
nal check has been carried out by your BMW partner. Nevertheless,
be sure to check the following points to exclude any malfunctioning that
may be due to the transport of your bicycle or to work a third person may
have performed on your bicycle before delivery:
1. Are the quick-release levers of the front and rear wheel properly
closed and the bolts of the seat post and other components correctly
tightened (a)? For more information see chapter “How to Use
Quick-Releases and Thru Axles”.
Improperly closed quick-releases can cause bicycle compo-
nents to come loose. Risk of accident!
2. Are the tyres in good condition and do they have sufcient pressure?
Make a “thumb test“ (b).
For more information see chapter “Wheels and Tyres”.
3. Spin the wheels to check whether the rims are true. Watch the gap
between rim and brake pad or, in the case of disc brakes, between
frame and rim or tyre. Untrue rims can be an indication of tyres with
ruptured sides or broken axles or spokes.
For more information see chapter “Wheels and Tyres”.
4. Test the brakes while stationary by rmly pulling the brake levers
towards the handlebars (c). The brake pads of rim brakes must hit the
rim with their entire surface without touching the tyre. You should not
be able to pull the lever all the way to the handlebars! The same ap-
plies to the brake levers of disc brakes. You should not be able to pull
them all the way to the handlebars! Make sure there is no brake uid
leakage. Also check the thickness of the brake pads.
For more information see chapter “Brake System”.
5. Let your bicycle bounce on the ground from a small height. If there
is any rattling, check where it comes from. Check the bearings and
bolts, if necessary.
6. If you want to ride on public roads, make sure your bicycle is
equipped according to the regulations of your country (d). Riding
without lights and reectors in dark or dim conditions is very danger-
ous, because other road users will see you too late or not at all. A set
of lights that corresponds to the regulations is a must on public roads.
Turn on the lights as soon as dusk sets in.
For more information see chapter “Legal Requirements for Rid-
ing on Public Roads“.
