8.0 Maintenance
Have your A2B checked by an Ultra Motor dealer at least
once a year.
8.1 Wheels
The front and rear wheels should
be centred in the fork and frame.
Wheels should be checked regularly
for proper spoke tension and rim
alignment. DO NOT ride your A2B if it
has broken or missing spokes. Wheels
should rotate smoothly without
wobbling from side-to-side or up-and-
down.
8.2 Hub bearings
Check the hub bearing
adjustment periodically by
lifting the wheel off the ground
and spinning it and try to
move the rim from side-to-side
between the fork or frame.
No lateral movement should
occur. If you detect lateral
movement in either wheel, the
hub bearings must be adjusted
or replaced.
8.3 Wheel rims
The rims must be smooth,
without cracks, bulges or
flat spots. Take your A2B
to an Ultra Motor dealer or
qualified bicycle mechanic
to repair and/or adjust your
wheels if necessary.
8.4 Drive chain
Your A2B has a high
quality chain that
needs to be cleaned
and lubricated
regularly with bicycle
industry approved
synthetic lubricant.
