noisy EZ3

I own a Sun EZ3 SX. Have had no problems at all with it. I've put about 400 miles on it this past summer and fall. Loved it so much, I wanted a tadpole and bought a Greenspeed Gt-5. But I will keep my Sun and ride it too. It's a great trike, in my opinion.

I did hear when I got mine that older 2005-2006 EZ3's had a bad axel (chinese manufacturing problem). They weren't truly round which caused the ball bearings to get bent out of shape. If you are having the same problem, and it sounds like it, get in touch with the people at Sun and get their advice. Especially do this if your local dealer doesn't have the knowledge to handle the problem.

Could someone please assist me? Two weeks ago, my husband and I bought two Sun EZ-3 SX Trikes. When we test drove mine (it was already assembled at the authorized bike dealership), it was as smooth riding and quiet at a dream. They said they had to assemble my husband's and do a final "tune up" on mine before it was ready for pickup. We came back 2 days later and picked up the 2 bikes. Before we left the parking lot, they had to replace my rear right-hand side bearings due to noise. After only 2 miles of use, we returned to have the rear left-hand bearings replaced. The "reason" they gave us was that the tech tightened the bolt too tight, thus damaging the bearing assemblies. We were told by the Manager that some squeaking and clicking is normal for the recumbants, because of the elongated chain and complex rear gear housing. However, here is my new and rather disturbing problem. The very bike that we had issues with from the beginning is now making a knocking sound AND strong vibration (when it knocks)...the sound is coming from the left rear...but it doesn't make the sound or the vibration if you lift the wheel and spin it. It only happens when someone is actually ON the trike...even if you simply move the wheel 1/5th of a rotation. Sadly, this has come up with only 6 rides totally 90 miles on the trike. My husband's trike is a bit noisy (squeaky) but NOTHING compared to mine. You can actually hear me coming or going without 600 yards. Now, please do not laugh Gentleman...this is NOT a "lady thing"...no matter who rides my trike they get this same situation. We're planning on taking the trike back to the dealer this week, but I'd love to get another mechanic's opinion on this. I know there are Lemon Cars...are there Lemon Bikes??? Or did I simply purchase this trike from a dealer with poorly trained techs? Either way, I'm almost afraid to ride it now...and it's extremely frustrating because I love the way it handles...if I could just get rid of the vibration and noise!
Thanks, in advance, for any assistance I can get on this matter. My husband and I love the bikes...but they aren't doing us any good if one cannot be ridden due to mechanical issues. By-the-way...if I didn't mention it earlier...they are 2005 Sun EZ-3 SX Trikes. We added fenders to them...but the bearing issues arose before the fenders were ever added (they lost the fender order and had to reorder).

The OP who was looking for an answer has not posted on BF since the original post in 2005. The other person looking for help hasn't posted in several years, either. (geeklpc1985)

Wow! Old- so old I forgot I had replied. At that time I had the EZ-Tad SX (yes, chain problem easily repaired) which I still have, and an old delta SX because it stands up on the back wheels easily for storage. No problems with either of these but I also have a Catrike- which has made up for the problem-free times. I got the Cat to use when moving but it is too small, low, crazy twist shifters, unadjustable seat angles; so the trike now makes a nice loaner to visitors!
