DAMN sexy bike and great post!!Answers from my perspective as an owner of a Crosstour with 300miles:
R&M has wonderful bikes. I've ridden many models. Their suspension is amazing. Shifting is sweet with the integrated Bosh/Rohloff system. But the power is lacking, and there's no throttle. Don't think you want/need a throttle? Then you've never had one, lol.
Watt Wagons builds exactly what I was looking for. Bafang 1000 Ultra and Gates, the best breaks, and best... everything. All the components are top of the line.
Pushkar's been wonderful to work with.
Delivery time? Don't know. Worth waiting for.
While it's not as uniform/sleek a style as bikes with proprietary integrated batteries (which can be a problem in servicing anywhere but the manufacturer), the Titanium is gorgeous! The bike is gorgeous.
VERY nice ride on both Crosstour and Commuter. Pro. I've ridden both. I thought I was sacrificing by not having rear suspension, but the top-end Kinekt post is perfect.
The 2000K option? Death wish! I went with the 1000W, and OMG it's definitely more than I need, and I ride fast! I rode my previous ebike in power level 5, 100% of the time. My WW has an ECO and SPORT mode. I ride in 1 or 2 (rarely 3) of Eco. I mean I was going 35 MPH on it recently! Scared the bejesus outa me, LOL. I tried it on 5 Sport once and immediately blurted out "Oh s**t! Oh s**t! Oh s**t!"
It's all about your priorities and what you can afford. I wanted the most powerful motor (with strong torque) available, with a Rohloff hub, a Gates drive and a throttle (and the brakes to stop it). The only folks I find in that market are HPC, FLX, and Luna. There's Optibike too, but they have no pedal assist, it's throttle ONLY). I won't go into my comparison of those, but to say I chose a WW.
Best of luck in your journey.
