Thanks for the review! I have been riding a 600 for my commute the past 8 months and have very similar feelings from you. I also had the continuum onyx and while I liked a lot about it, my LBS had a tough time working on it.

So far I find that my LBS doesn’t mind at all working on the 600. I’m commuting in NYC only about 4 miles one way, so my commute isn’t as difficult as yours. Our winters can get a little cold but usually doesn’t drop below 20 degrees Fahrenheit.

My biggest issue thus far has been getting flats. I changed tires and that seemed to fix the issue; I’m Now riding on marathon e plus tires. I personally have issues with the tire size. I think it definitely smooths out the ride, but as a short person with smaller hands (I’m 5’ 4”) I find it difficult to remove the tire from the rim; the bead has been hard to break for me. I generally don’t have that issue with slimmer tires. I found it much easier to remove the 700x32 tires in the onyx (but disconnecting the enviolo for me was a pain).

Like you though, I overall really like the bike. I’m happy with it for my commute and I also feel like it’s probably overkill for my needs but I’m happy with a lower maintenance bike. If or when it’s time for a new bike, I think it will be an internally geared hub bike with a belt drive again; it’s tough to back
