Two weeks ago I picked up my new Cube Kathmandu. It is perfect for my rides. Unfortunately there is little to no availability of this bike in the U.S. for some reason right now. I had to drive from Seattle a couple of hours north to British Columbia to pick up the bike but it was well worth it. I declared the bike at U.S. Customs on the trip home, and after about a half hour delay, the officer determined no duty was due (as the dealer had predicted). If the bike needs warranty work, I am hoping I can work something out with the local Cube dealer (who was unable to order this model for me). If that fails, I can always make the pleasant drive to Canada for any warranty work. I'm always looking for an excuse to visit BC anyway.
It has the new Bosch Performance CX mid-drive motor and the 625 Bosch PowerTube battery. The smooth torque has been great in my very hilly Seattle neighborhood.
The overall build quality of the bike seems outstanding. It has all the features I was looking for: Latest generation Bosch CX motor, front suspension, large battery, great build quality, integrated lights, suspension seat post, adjustable stem, hydraulic brakes, wheels and tires suitable for pavement and gravel trails, fenders, and integrated rear rack. The shifting is very smooth.
This bike has the Bosch motor that is limited to 20 mph. A more expensive 28 mph speed version is available, but it appears the speed version torque curve is somewhat different with less torque available at lower speeds, at least according to my internet research. Since hill climbing is the primary reason I wanted an ebike, I opted for the lower speed version. I was not able to actually compare the two motors side by side so I have no first-hand experience to test that proposition.
Since my rides are mainly in Seattle on urban streets and multiuse trails, and are for recreation, I felt I really did not want or need 28 mph. Commuters I think might prefer the speed version. For me, 20 mph limit for assist has been fine. For me, it would be absolutely perfect if the maximum were 22 mph, but now I'm quibbling.
I'll post more details as I ride it more, but so far I am thrilled. I can't wait for each daily ride.
