speed wobble?
Tryed googling this but didn't really get an answer.
Basically whenever I start up my handle bars wobble, sometimes I can get to full speed but hit a crack or go over a sewer and it'll do it too. Just kind worried.
I have a gio 500w +. goes up to 32km. What I wanna know is how to fix this problem? Can I? Or do I need a new part? which part?
Thanks in advance

Need more infomation. You should be worried. Close up pictures of the install would help.

The topic is hotly debated, but these are good summaries ...

This might or might not be what you're experiencing, but it's a good place to start.

Sounds like your front wheel is not attached tight enough..
Didn't you check that first? Sounds reasonable..
How about some more info as to what you've checked so far.

Could it be that round donut thing that tightens your handle bars on? What year was your bike made? My bike was made in 1999 and is a GT Outpost trail and any bike made pre-2000 have these inferior donut things right below their handle bars that tighen them but they were found to be inferior and have been re-designed since 2001 and I wonder if maybe you have one of those older bikes. Mine doesn't wobble but I'm always very careful with it.

I think it's called a headset and they've been redesigned. https://en.wikipedia.org/wiki/Headset_(bicycle_part)

Threaded headsets are not really "inferior". Threadless headsets have some relatively minor advantages, but none of these have anything to do with how effective or tight the steering is.
It's hard to tell what's wrong with your bike without having it front of us. You could make sure everything is properly tight to start with, and if that doesn't help ... take it to a bike shop or to a local friend who can fix his own bike and have him check it out.

A whole lot of mechanical snafus can contribute to “speedWobble”. Looks like you added a e-drive system to the bike. Adding a front hub motor and its weight on asketchy stock fork can be anything from annoying to death defying. I would havea local bike shop make suggestions. It’s always a good idea when adding a hub motor, to make sure thefork and dropouts are Chrome Moly Steel with a good quality, well adjustedheadset. Cheap suspension forks can also add to the problem.-CC
