of all the different frames that are a v shaped , mountain bikes , cruisers ; I would like some input on the different ways the chengines have been installed to reduce vibrations! I have done three builds. my first build was a little rough at first but with 1400 miles on it now it runs real smooth. I did put a 1/4" piece of rubber on the rear mount between the seat post and motor anf on the front mount (oversized down tube) I used a adapter plate and a u-bolt with a thin piece of fiber rubber and have very little vibes. the second build was a hybrid trek used the same mount technique for the rear and the front , I was able to use the motor mount directly to the frame and used the thin piece of rubber. at about 26-28 mph there was alot of vibration. and on my latest project on a cruiser I used a thin piece of closed cell rubber foam sticky back tape to mount the rear and a piece of 1/4" fiber rubber in the front . I have some vibrations at low speeds and alot of vibes at higher speeds. Iam hoping after a few 100 miles on it it will calm down. so I was just curious as to what kind of mounting methods are really out there, and a census as to what works best. ( a good seat will work wonders also)
