Hi Chaps,
my somewhat more than 2 penn'orth follows. It got longer as I went on!!
I recently got an eQ Xduro FS SE (
Haibike °eQ Xduro SE° E-Bike Elektro-Fahrrad Pedelec Bosch Rh 56 | eBay) from Germany for E2700. It's the same spec exactly as the FS RX, but black and red colour scheme which, IMHO, is much better.
I've only had it a couple of (crappy weather) weeks so haven't given it a proper workout yet, but so far, I'm very pleased with it.
It's got a really handy instant saddle height drop lever for serious downhilling, which is sprung so will go back to normal height without having to stop and mess about. Once the shocks are properly set to your weight, the ride is fantastic - way smoother than either my Cannondale or Kalkhoff, and it doesn't seem to waste too much leg power in bouncing the suspension up and down, which was always my reservation about full-sus. It's a high quality frame with very good quality kit. My only mods so far have been
1. to replace Presta tubes with Schrader (Schwalbe) tubes that only needed minimal reaming of the valve hole in the rim, and
2. swop the Fizik Tundra 2 saddle for a Brooks B17. It doesn't look so groovy, but it feels great.
I've still to get fully acquainted with it, but the Bosch system appears to knock spots off the Panasonic on my Kalkhoff in terms of adjustability and flexibility - it sailed up a very steep and slippery track through our local woods which had defeated the Kalkhoff, although to be fair, the Kalkhoff's not a full-on MTB, and I've put a 14t motor sprocket on it, which increases top end assistance at the expense of the bottom end.
Still, the Bosch is really impressive on hills. The only drawbacks I can find are two;
1. There's no easy way to increase top end assistance as with the Kalkhoff, so I'm stuck with the 15 mph cut-off. that said, the Haibike feels a good bit lighter than the Kalkhoff so it's not so hard to keep speed up beyond the assistance level.
2. Top gear is too low so I can't keep up with the pedals over about 27-28 mph. I'm trying to rectify that by putting on a 42t chainring instead of the existing 38t one. It'll hit the bottom end a bit, but the gearing's so low that I think it will actually make it more usable right across the range.
However (if anyone's made it this far

), I had to remove the chainring lockring with the aid of a Birmingham screwdriver as I couldn't track down the right size extractor tool, and as a result, whilst it all works fine, I now have a somewhat battle-scarred lockring

. The ring is about 5 cm diameter, and I'd be really grateful if anyone could point me to a source of both lockring and tool. I have hunted the web without success so far, and Bosch's website seems to have bits that are only accessible to trade users.
Here endeth the sermon..........
