The cable or lever was only if it had reverse. It won't have one.

So now it's in neutral, but it only pushes backwards, right ? You can't push it or drive it forwards..  right ?

I'd guess that would be a brake playing up. You could drop the drive chain off it and try turning the back wheels then. Or jack the front end and try turning that wheel.

I forgot to mention that when i'm engaged on any gears other than the netral, I can't move forward and only backward. I don't know if it's possible but maybe the whole gear system is upside down.

i'm pretty sure it's not the brakes, it blocks completly and if I try pushing it forward, it's making a sound like two gears rubbing because they can't support the force a bit like if you put reverse while moving forward. I figured out how to move forward by rocking it back and forward so now it's in neutral i guess because i can move forward and backward. There is still something wierd: the others gears are when i downshift but it's supposed to be the opposite.        Sorry for the wait, I wasn't able to send the message.

It's been a long time since I've seen one of those, but it will be as Gw says and something in the shift mechanism rather than the clutch.

First off I'd check there isn't some lever or cable that has to be used to put it into reverse.. That part might be playing up and stopping the shift lever from moving.. perhaps.

If it's not a designed shift lock, then I'd try rocking it backwards and forwards while trying to get the shift lever to move. Sometimes we have to push the bike quite hard in one direction or the other to get the engine to turn and allow a shift to happen. Decpmpressing the engine will help, or, jack the back wheels up and turn them while trying to move the shift lever.

If that doesn't work, describe how the shift lever behaves/feels.. is it solid and not move at all, does it move freely but do nothing, does it move the usual distance both ways, does it self center ?

I succeeded to put it in neutral but i'm still not able to go to the 1's, 2's, .... 5's speed.

I've looked at several years now and no reverse..  Seems more likely it can only be pushed backwards, which could be because it's in gear and the over-run/sprag clutches won't let it go forwards, or, the brake is playing up, loose lining on the shoe perhaps..

lIndeed, there is no reverse. I'm pretty sure it's not the brake that is playing up,  the wheels are completely blocked when i try to move forward. Where is the over-run/sprag clutch and what is it's fonction?

where would this lever/cable be if there is one?

Oh..  The manual I just looked in says that bike doesn't have reveres. Does it have reverse gear?

And are you saying it drives in reverse ? Or that you can only move it backwards ?

I can only move it backwards but I manager to put it in neutral. You’re right, there is no reverse, I checked in the user’s manual but how is it possible that it does not move forward but can move backwards?

Can somebody help me? I am actually working on my three wheeler and I don’t know what to do: I can’t shift gears. I think it’s in reverse (because I can’t move forward but I can move backwards) but I can’t shift to any other speeds not even the neutral.
