The rear suspension on my red delta has developed some sideways play. The brackets for the suspension were taken off the donor bike and the trike now has prob a few thousand km's on it. Grabbing the seat back it is possible to induce some sideways motion. I did take the pivot point apart, found no noticeable wear. So it got a light coat of grease and was reassembled. Just wondering if anyone here with a delta has had the same issues. Mine is based on the Aurora plans. On another note it just had the previous mid drive motor removed and a 500 watt front geared hub installed. On it's first ride this spring I must say I'm liking the front motor.
