Just got mine but the chain keeps poping out of the rear gear. Why??

I have not had any issues.... I would loosen the back tire and check the alignment and re-tighten.

I've never had that problem, we put a lot of miles on our co-pilot. Maybe it's a defect?

I Haven't had any issues . Might need to adjust the back axel . Loosen the back tire so the chain gets tighter make sure the gap is the same on both sides so the chain travels true.

You may have to change the bottom bracket to get the right chain alignment. Also I'm sure you will have to lower the the front derailuer. If your trying to lower the gearing of your road bike it may be easier to change the chain rings and rear cassette.

Make sure the gears are seated correctly. Mine did not work at first because I did not have the vertical gear pushed down far enough. I doubled checked my work by forcing the gears to turn using my fingers so I could see if everything was in the correct position.

Could be the chain brake is on- pull the hand guard to the rear to release. Or the chain is dry of oil & too tight. Or the chain was tossed off the bar and had drive links buggered. Loosen it some, move by hand, and find source of problem. All else fails, read the manual.

I have the same problem with the chain coming off. When I used it I spent far more time putting the chain back on than I was able to use the machine. Should have taken it back. Not usefull at all.

Is the chain off the sprocket? Is it your first time riding the zike. I thought mine was jamming up, but I found out my muscles were not used to a stairstepper motion ,so it was my leg muscles that needed fixing not the zike, now I can peddle 45 minutes at a time .You have to change gears 1 gear at a time. You cannot go from 1 to 6 all at once.I once had the chain come off the sprocket. I got it back on by rolling the bike backward, it was the only way. It would not go on rolling it forward. Not happy with the gear shifter. I shift from 4 to 5 and it goes to 6. Hard to get it in 7th. I love the zike. I have 2 other bikes , a GT and a nishiki, and I only ride the Zike.

I found that you have check every so often that bits of wood/branches do not get into the back of the chain, if you stop every once in awhile to pull out the accumulation that makes a big difference. Also you have to adjust the chain if it is too loose that will make the chain slide off.

Maybe a few things. Chain to tight. Shaft cable broke or binding(cable inside the long metal shaft) . Maybe the keyway on the engine crankshaft spline sheered. Debris jamming the chain under the chain cover. Good luck. Hope this helps.

There is also a little button on the side, that when put in the off position, may solve the problem. Also, while you are at it check to see if the rear holding bracket is not loose.

You must take apart the handle and adjust the gear by spinning it clockwise, then replace the little washer, put the crank handle back on and test it. If it is grinding very easily then your gear is too loose.

I don't think I had the same problem. Use an appropriate sized bronze bushing or even a few washers on either side of the clutch-it doesn't matter really just make sure it doesn't slide around. Or you could cut the end of the crank shaft, but I wouldn't unless you know what you're doing.

just get a new chain and you should be ok if you have a good tech. It shouldnt impact it. I have a 105 group with Ultegra cassette and dura-ace chain.

I have no issues with the bike except it could have a tighter seat. Call a local bike company and maybe they could help you.

If you are having this issue, go to Walmart or an auto parts store and buy a small tube of lock tight. This will stop that from happening. I have put over a thousand miles on my bike and the pedals have never needed to be tightened.

I see you've been waiting for an answer for a long time. I have the very same question. It looks like on all the units I've seen that you have to thread the chain through them, which would be easy for chains on geared bikes. I'm gonna guess that it would be a problem using one of these which would be a shame.

Mine is slightly out of true laterally. Freewheel ready. Just have a chainwhip.

I am so sorry, I have never had that problem. I would have a Schwinn expert help you with that. Sorry, and best wishes.
