Halfbike 3 - Gear Hub Adjustment
For adjusting the gear hub of your Halfbike 3 you can check this tutorial:
Move the shifter to gear number 2.
Check if the two yellow lines are aligned well. *
Rotate the shifter cable adjuster to align them.
Select gear 4 and then change back to gear 2.
Rotate the pedal cranks a full turn and then check again to ensure that the two indicator marks are still aligned.
Repeat the above steps until the yellow indicators are aligned.
* Please note that the two lines are not 100% accurate on all hubs. Some do shift better when the lines are slightly out of position and it takes a bit of experimenting to find the optimal position.
Thanks for the tip Martin.
Thank you very much Martin.

Hi guys, tried several times the tutorial but althought the yellow lines are aligned, switching from second gear to third or fourth, I keep hearing a cranky noise. is there any other check/adjustment I should try? Many thanks
I’ve tried to adjust the gear hub at least 50 times following the instructions on this tutorials. I tried multiple settings, leaving the lines slightly out of position or perfectly aligned, but the result is always the same: the only gear that works is second. When shifting to third, it momentarily engages, only to go back to second and make a cranky noise. Same thing happens when shifting to fourth.
I have used this half bike for about two months and only sporadically, so it has no more than 40 miles of use. It’s really frustrating to realize that I might have just wasted the $750 I spent on it because it appears the gear hub has a design flaw.
Is there anything else I can do to get the gear hub to work properly?
Just sent you an email :) We'll o our best to help out.

I'm having the same exact issue. I just got my half-bike today and put it together. Without even riding it I hear this annoying noise. At first I couldn't understand what it could be. Then, after looking over this "thing" I dis-engaged the gear cable and it didn't make anymore noise. However, once I engage the gear cable back to the main wheel the damn stupid noise came back.
Do I have a defective gear hub right out of the box??????? This sucks!
Just replied to your email. You've placed your gear cable on the wrong side, that's all :)
i seem to have issue too, the 2 yellow marks are about 4mm off and i cant adjust them anymore, and when i switch to gear 3 , there is always this weird cranking sound, only gear 2 doesnt have this sound. can anyone help me>?
