These routines require a certain amount of
manual skill and (special) tools. Ask your bicycle
mechanic to explain to you both function and
adjustment of your stem or let them do that
work.
The bolted connections of the stem and
handlebars must be tightened to the
prescribed torque values. If you disregard the
prescribed values, the handlebars or stem
may come loose or break. We recommend
only allowing a qualified bicycle mechanic to
perform any adjustments.
Stems come in very different lengths and
shaft and binder tube diameters. A stem of
inappropriate dimension can become a source
of danger: Handlebars or stems can break,
resulting in an accident. When replacing any
parts, be sure to only use parts that bear the
appropriate mark and, to be on the safe side,
original spare parts. Your FISHAW customer
service representative will be pleased to help
you.
Make sure the handlebar clamping area
is free of sharp edges. Make sure the
handlebar/stem combination is approved to
be used together.
Conventional Stems
Handlebars with conventional stems allow
limited vertical adjustment. This is done by
moving the stem up or down inside the fork
steerer tube. The UB200 Urban model has a
conventional stem.
Release the expander bolt by two to three
complete turns. The stem should now turn
freely inside the fork. If it does not, release the
bolt by tapping it gently with a rubber hammer.
With Allen bolts you need to stick the Allen key
into its head, first, as it is normally countersunk
and therefore impossible to be hit directly.
Now you can move the handlebar/stem unit up
and down as a whole. Be sure not to pull out
the stem too far. The mark on the stem (end,
min, max, stop, limit or the like) should always
remain within the tube. Setting the stem to a
lower position can only add to your safety!
Realign the handlebars with the front wheel.
Retighten the expander bolt with the correct
size Allen key.
Tighten carefully and check the proper fit of
the component in between. Never exceed the
maximum torque value indicated by the
manufacturer! You will find the prescribed
values, directly on the components and/or in
the operating instructions of the component
manufacturers on their respective websites.
Check the seat of the stem by taking the front
wheel between your legs and trying to turn the
handlebars and stem relative to the wheel. If
there is movement, you must tighten the
expander bolt. If the handlebars are still too
high or too low, you can replace the stem. This
can be quite a big job, as it may mean taking
off and remounting all the fittings on the
handlebars. Ask your FISHAW customer service
representative or your bike mechanic for
advice about the different types of stems.
Never ride a FISHAW electric bike with a
stem that has been drawn out beyond the
mark for the maximum permissible height!
Check all bolted connections and test your
brakes before you set off in an area free of
traffic!
Never try to unscrew the top race of the
headset when you only want to adjust the
stem, as you will otherwise alter the bearing
play!
