I have an ST-2 that is in excellent condition with approximately 3000 miles or so. Stromer folks helped me to add the new Omni C which my engineering son installed it for me. My saddle has a Brooks brother saddle as well as the Cirrus suspension on the seat suspension. I have treated it extremely well, never ridden it in the rain and polished it up on a regular basis. My local dealer went over the whole bike towards the end of this November when I put the bike up for the winter coming and says it is running perfectly. He cleaned up the cassette, derailleur and chain while re-lubricating it, so it is good to go for this coming Spring. I turn 83 tomorrow and would like to pass the bike on to someone whom might be interested in a beautiful Stromer ST-2. It is up for sale at $3000 which I paid $6999 for it in 2017.
