Seat (saddle) and seat post

WARNING!

Adjust height, position on rail and tilt of seat to a

comfortable position. Do not continue to ride if you feel pain,
discomfort or numbness while riding.

WARNING!

If seat post is too high and not inserted at least

12cm (4.7 inch) into frame, the frame may break and cause
injury. The minimum insertion mark must not be visible when
seat is inserted into frame. The minimum insertion mark is
printed or engraved on the seat post. You may have to look
closely to identify it.

WARNING!

If nuts, bolts and quick‐releases are not tightened

safely the seat position may change unexpectedly during ride
and cause injury.

Caution!

When you open the quick‐release the seat may drop

down and present a squeezing hazard. Always hold the seat
with one hand to prevent it from dropping and operate quick‐
release lever with other hand.

Headset

The headset is the system of bearings which sits around the
handlebar and fork it needs to be checked every 30 days by
applying the front brake while moving the bicycle back and
forth. To check if steering is smooth, lift front wheel off the
ground and steer left and right. If there is excessive movement
or if steering is not smooth, the headset needs to be adjusted
by a bicycle professional.

Chain

Check chain tension every month. If it is too lose use derailleur
to adjust tension. Check all links of the chain. If there are any
stiff links, apply lubricant and try to move them carefully by
hand or have them replaced at a bike shop.

For bicycles with rear suspension, point the nose
of the saddle down slightly. When you sit on the
seat, the rear shock will compress and the seat will
be level.

Inspection

: Before each ride make sure all nuts bolts and quick

releases are safely installed. Use both hands and move seat left
and right or up and down. If seat moves easily, tighten bolts.
Make sure the seat folding hinge is closed. Inspect seat‐post
every 30 days to make sure it is straight. If it is bent, contact
customer service.

quick‐release mechanism.

The model SuperT does NOT have a folding seat post. The seat
needs to be twisted to remove the battery.

Bike stand (Kick‐stand)

Make sure the stand is fully retracted before riding
the bike. The stand is designed to only carry the
weight of the bike. When you are on the bike, do
not lean against the stand. Do not use the stand if
there is any luggage on the bike. Do not use the
stand if there is a person on the bike. Make sure
that the stand does not hit obstacles while riding. If
your stand hits obstacles while riding, adjust riding
style or remove stand. Every 30 days check if the
stand is attached safely to the bike. Tighten stand
attachment if needed.

WARNING!

Always hold onto

bike when loading bike to prevent falling. Do not
assume that the stand alone supports the bike.
