I took one (M20) for a spin last weekend and really liked it. it is well put together and the new bosch motor felt really good, with quick response time, low noise and the right assist when I needed it. My test was limited to urban trails and a dirt mount, but still, the bike behaved as expected and was relatively light and nimble. I was concerned with the geometry of the front wheel where the angle is more pronounced than my Levo (less slack), but it was still sure-footed and didn't feel I was going to go OTB in any of the steep descents I tried.
Overall, the bike built was of high quality and the addition of the range extender (available in April/may in the USA), is making this bike a compelling contender for my next bike purchase.
