HOW TO USE THE EXERCISE BIKE

HANDLEBAR OPERATION

You can use the handlebars in the dual-action mode, 
for upper- and lower-body exercise, or in the stationary 
mode, for pedaling exercise only.

Dual-action Mode

To convert the handlebars to the dual-action mode, the 
link arms must be connected to the pedals. 

First, lift the link arms off the lock rods. 

Next, pull the link arms outward against the tops of the 
blue washers, while pulling against the bottoms of the 
blue washers with your 

 ngers as shown. 

Be careful 

not to pinch your 

 ngers. 

Next, slide the link arms 

onto the pedal bushings. Move the link arms upward 
and downward slightly to make sure that they are fully 
seated on the pedal bushings. 

CAUTION: Make sure 

that the link arms are fully seated on the pedal 
bushings. If the link arms are not on the pedal 
bushings, they may slip off during use, resulting in 
injury to the user.

Stationary Mode

To convert the handlebars to the stationary mode, 
the link arms must be disconnected from the pedals. 
Pull the link arms outward against the blue washers 
until the link arms are free of the pedal bushings (see 
drawing 2 at the left). 

Be careful not to pinch your 

 ngers.

 Next, lift the link arms off the pedals, and clip 

them onto the lock rods (see drawing 1 at the left).

HOW TO ADJUST THE SEAT

For effective exercise, the seat must be at the proper 
height. As you pedal, there should be a slight bend in 
your knees when the pedals are in the lowest position. 

To adjust the seat, 

 rst turn the seat 

knob counterclock-
wise two or three 
turns to loosen 
it. Next, pull the 
seat knob, raise or 
lower the seat post, 
and then release 
the seat knob. 

Move the seat 
post upward and 
downward slightly 
to make sure that 
the pin on the seat 
knob is engaged in one of the adjustment holes in 
the seat post.

 Then, tighten the seat knob. 

CAUTION: Make sure that the pin on the seat knob 
is inserted into one of the adjustment holes in the 
seat post. Do not rest the seat post on top of the 
pin on the seat knob.
