8. Now plug the charger into a power point and turn on the power at the wall. Lastly, switch on
the charger (the charger’s I/O switch is next to the 110/240v power input cable). One light
will show red, and the other will show orange (charging). The orange light will turn green
when the fast ‐ charge cycle is complete. It is best to charge overnight for the first 3 charge
cycles, as detailed in the user guide.
Note: When charging, always the last step is to switch the charger switch on. This
allows the charger to properly sense the battery charge levels.
9. Slide the seatpost into the frame and tighten the quick ‐ release lever. If the seat is not firm
with the lever fastened, fully fold the lever back again, then tighten the adjustment nut
clockwise a half turn. Fold down the lever again and retry. Repeat until the seatpost is held
firm.
10. Slide the plastic cap off the handlebar headset stem ‐ post ,
then slide the stem ‐ post into the bike.
11. Lift the quick ‐ adjust lever on the headset and alter the
headset angle until you can fit the supplied largest allen
key into the nut on the top of the stem ‐ post. Make sure
that about an inch of silver stem ‐ post is showing (you can
adjust the final height later) and that the handlebars are
aligned with the forks, then tighten this nut until the stem ‐
post is held firm.
Note : recheck and tighten this very firmly, once
the front wheel is installed later.
12. Depress the quick ‐ adjust lever to lock it in place again.
13. Carefully turn the bike upside ‐ down and lay it on a rug, or soft surface to avoid damage.
Lean it against a chair or wall to avoid it tipping over.
14. Remove the plastic axle rest from the base of
the front forks.
15. Remove the disc brake plastic gap spacer
from inside the front disc brake unit.
16. Remove the protective end ‐ caps from the
axle of the front wheel and loosen the axle
nuts until they are near to coming off the
ends of the wheel axle.
