VII. Operation
Before you ride:
Use the following checklist to insure that your Ultra Motor electric bike is ready for safe
and enjoyable use.
•
Quick releases
: Make sure that your front wheel quick release and your seat
height adjustment quick release are properly adjusted and tight.
WARNING: Failure to properly adjust and lock your front wheel quick release
may result in the inadvertent separation of the front wheel while you are riding
the bicycle. This occurrence can result in serious injury or death, and property
damage. Please refer to the instructions on beginning on page 14 for the proper
installation and adjustment of your front quick release hub.
WARNING: Failure to properly adjust and lock your quick release seat post
clamp may result in inadvertent movement of the seat while you are riding your
Tres Terra electric bike. This occurrence could result in the loss of control of
the bicycle resulting in an accident that could cause serious injury or death, and
property damage. Please refer to the instructions on Page 17 for the proper
installation and adjustment of your quick release seat post clamp.
•
Wheels
: The front and rear wheels should be centered in the fork and frame.
Wheels should be checked regularly for proper spoke tension and rim alignment.
Do not ride your Tres Terra electric bicycle if it has broken or missing spokes.
Wheels should rotate smoothly without wobbling from side-to-side or up-and-
down. Check the hub bearing adjustment periodically by lifting the wheel off the
ground and spinning it.
Note: The rear wheel turns in the forward direction easily, but with considerable
resistance in the reverse direction. This is normal and due to the gear mechanism
incorporated into the motor hub.
To check the adjustment of the hub bearings, try to move the rim from side-to-
side between the fork or frame. No lateral movement should occur. If you detect
lateral movement, the hub bearings must be adjusted or replaced. The rims must
be smooth, without cracks, bulges or flat spots. Rims should be clean and free
from dirt, grease or other contaminants. Periodically clean the rims with a
solvent, such as denatured alcohol. DO NOT OIL the rims as this will affect
braking performance. Take the bike to a qualified bike mechanic to repair and/or
adjust your wheels if necessary.
•
Tires
: Your Ultra Motor bicycle tires normally lose pressure over time. An
under inflated tire can cause premature tire failure, and will require significantly
more energy (electric and human) to propel the bike. Low tire pressure will have
a significant negative impact on range under electric power. Insure that both front
and rear tires are inflated to the recommended tire pressure indicated on the
sidewall of the tire. Check the tires for any damage or unusual wear. The tire
