Your bike has a rear derailleur that will automatically tension your chain.
However if the chain becomes loose or frequently comes off the front cog, you
can easily adjust the chain tension by loosening the rear axle nuts slightly, and
adjusting the tension bolts. Make sure that the chain runs freely and re tighten
the axle nuts.

The brake leavers should lock the wheels when compressed half way between
their open position and touching the handle bars. When they need adjusting
please follow the instructions on our web site www.wisperbikes.com Electric
Bikes, Manuals.

Warning
Handlebar hand grips or tube end plugs should be replaced if damaged,
as bare tube ends have been known to cause injury.

Warning
If replacing forks they must have the same rake and same tube inner
diameter as the originally fitted to the bicycle.
IMPORTANT braking distances increase on wet or icy roads.
