3. How TO ASSEMBLE THE EBIKE
Before Installation
When unpacking your e-Bike, please verify that the above items are included in the package. If you are missing any components,
please contact your dealer for support. After verifying that all components are present and in good condition, you can
assemble your new e-Bike.
Please keep the box and packaging materials for a while in case you need to ship your GM30 in the future.
Step 1. How to assemble the front wheel
1) ) Remove the front fork protector from the front fork. (Please note: front fork protector is used to prevent the fork
from being deformed during transport. It belongs to the packing material. You can throw away it!)
2) locate the front wheel and front wheel axle.
3) Lift the frame/fork and place the front wheel in the bike’s fork.
4) Make sure that the disc brake is well placed in the middle of the brake caliper.
5) Insert the axle all the way through.
6) Hand tighten or loosen the thumb screw to the proper position, then close the Axle latch. Test and make sure the wheel does
not wobble.
If something appears to be wrongly assembled - even if you have followed the instructions, please contact us before riding your
GM30
, or take to your local shop to have it thoroughly checked.
IMPORTANT: Attach the wheel securely. A loose or detached wheel can cause you to lose control of your GM30 and fall, and
could cause you serious injury.
