    Great bike, smooth and comfortable... heavy but once rolling it moves like a bowling ball without even needing to keep pedaling.

    Great bike. Had it professionally assembled for only $50. Great for gravel and road cycling.

    Great bike!
    This is a well designed, comfortable and fast bike. It's my daily commuter and I plan to tour with it. Well worth what I paid.

    Doppler Pro does the job.
    I am in love with my new Doppler Pro. Smooth riding, good overall components and parts. Hydraulic disc breaks as very responsive. Like others have mentioned, it is not the lightest in this category, but it rolls very nice on hard surface once it gets speed. I like the retro look. Have received lots of praise from friends. It has its own vibe. It is my daily commuter and will take it out on short multi-day gravel trails.

    Perfectly adequate for solo riding.
    The Good:
    Came almost fully assembled, and it was easy enough to get the brakes and shifting dialed in with the help of some youtube videos. I was pleasantly surprised at the performance of the Hy-Rd brakes. Not a grabby as straight hydraulics, but noticeably better than mechanical discs I have ridden, and way easier to adjust.

    The not so good:
    The chainrings had extra material leftover from manufacturing that had to be removed with a file before it was in riding shape (possibly why it was a deeply discounted warehouse sale).

    There's a good number of mounting points on the front, but it lacks the braze-ons for a conventional rear cargo rack. You can double-up on the rear fender mounts, but make sure to account for the extra height when buying the rack. A rack for 26" wheels would probably give the right clearance, but my old road rack sits too high to load up without seriously throwing off the balance of the bike.

    The personal opinions:
    The frame fit is a little odd. Breezer markets this for gravel, commuting, and bike packing, but it's a challenge to get the bars up where they should be (i.e. above the seat). At 30+ lbs, this rig isn't going to keep up with many racing pace lines, so Breezer should leave a few extra cm on the steerer tube so I rise up out of the sport racing position without getting into the world of wacky after-market riser stems.

    Great value
    Had the bike assembled by the LBS. I wanted steel, ability to pull a trailer without worrying about breaking anything, and needed to be able to bike over grass and crappy Wisconsin roads without worrying.

    This checked all my boxes, the 650b wasn't something I was seeking, but I've really enjoyed the horizon tires it came with.

    Only minus is the brakes. I took the hy/rd to two different bike shops trying to get them to work properly. The original shop that assembled them I'm convinced messed them up in some way messing around with them so many times. I bled them, re-adjusted, took them back to LBS. The front one just never worked properly. The rear one I could lock up at any speed. I ended up replacing with a full hydraulic system.

    What parts are not assembled?
    SIDNEY W on Apr 21, 2020
    BEST ANSWER: Not to sell you something else but we do have an $99 assembly fee that gets the baike 99% of the way done so its easy for you to finish it when it arrives. This also includes to shipping which is great because bikes are not included in or free shipping promotion. Plus with all of the bikes stores closed because of the pandemic this can be invaluable right now.
    The description says hydraulic disc brakes but the photo shows mechanical disc brakes. Can you confirm what is actually offered on this build?
    Kinsey V on Feb 17, 2020
    BEST ANSWER: They are actually the excellent TRP HyRd. They are cable operated hydraulics, and work flawlessly. The best of both worlds, in my opinion!
    What will need to be assembled once delivered to me?
    Shane C on Apr 3, 2020
    BEST ANSWER: If you don't mind voiding the warranty (if it even applies to warehouse stock) home assembly is definitely do-able. I had to right the stem, tighten the stem cap, attach the handlebars (already cabled and wrapped), install the front fender, and put the wheels on. Also had to spend a little time dialing in the derailleurs and brake cable tension, both of which were super easy with the help of a YouTube video or two. All told, it took a little over an hour to get it road ready. New brake cables will always stretch a bit, so you'll need to readjust them after your first couple of rides until they settle in.
