lock Bolt 2.

15   The front connection box

 

15.1 

The front connection box allows for the easy removal for repair                           
or replacement of any of the electronic components on the handle 
bars. 

 

16   Quick release saddle height adjustment 

16.1 

Your Wisper bike has been fitted with a quick release saddle post collar to 
facilitate the movement of the saddle to remove the battery or to change the 
riding position. 

16.2 

It is important that the nut on the collar is tightened so the post will move in 
the bike tube firmly. Make this adjustment with the quick release lever in the 
open position. 

16.3 

Adjust the seat to the correct height and close the lever. When you sit on the 
saddle there should be no vertical movement at all in the saddle post. 

 

17  Saddle post suspension 

17.1 

For your comfort your bike has been fitted with saddle post suspension it has 
been set for a person weighing 75kg. If you are lighter than this you may not 
feel any benefit and if you are heavier you may feel the suspension bottoming 
out.   

17.2 

The suspension post can be adjusted by removing the whole post with saddle 
attached from the bike. On the bottom of the post you will find an alan key 
adjuster simply turn it clockwise to tension the spring for heavier people and 
anticlockwise to release tension for lighter people. 

 

IMPORTANT never raise the saddle past the point where the maximum marks on the   
saddle post are visible above the quick release collar 

 

18    Rims and spokes 

18.1 

It is essential to get your spokes checked and tightened after 300 miles. This is a 
free service provided by your supplier. If this service has not been undertaken at 
the correct time this may cause damage to the wheels and spokes that will not 
covered under our guarantee.
