I bought a Cube LTD 29er earlier this year. I have been very impressed with this brand of bike, the build quality is very good, frame geometry comfortable and it is well equipped.
At the moment, it has 2.00 Schwalbe Big Apple tyres fitted and it makes a great road commuting bike, so much so that my electric bike (Pro Connect) has been redundant for the past three months.
The 29 inch wheels roll very well and the Big Apple tyres are fine for light / moderate trail riding as well as road use. In summary, its a very well made versatile bike. And interestingly, I can cover the 20 mile round trip to work and back quicker on the Cube LTD than on my electric bike. I think this is because the Cube is higher geared and I can pedal it to a higher speed.
A Bosch driven electric version would make a great machine. The 29 inch wheels on a MTB makes a huge difference and I wouldn't consider anything with 26" wheels now.
