That sounds good thanks, pretty much maintenance free then!!!

That's no problem, the motor cable is a good length & I've installed it with a good drip loop. What about lubrication of hub bearings etc?

As title really. My XF07 front hub has reached about 650 miles now, still less than 6 months old & upto now almost faultless. I say almost, as a couple of months ago I noticed what sounded like a 'plasticky' cheep cheeping kind of sound coming from the front hub after a few minutes of use (only under pedal assist/throttle, not 'coasting.' It cleared itself after being evident for a few days and I haven't heard it since, it may have been something to do with the onset of cooler weather? Anyhow, that's by the by. Back to the original question; is there any specific maintenance which would be beneficial to prolong the life of the hub motor? I am well aware of the old adage "if it ain't broke...." but if there is anything a reasonably competent mechanic could perform then it would be good to know. Cheers, Simon

Just as a follow up, after completing just over 600 miles on the above mentioned configuration (24 inch wheel size entered for 700C tandem) I again noticed a pretty large discrepancy between actual speed & that displayed on the KM529. I therefore entered a wheel size of 700C to the menu &, lo & behold, everything now tallies. The speed & hence distance now correlates with reasonably well calibrated other sensors, very strange but also rather satisfying!!

OK thanks for that, thought maybe I could plug a light in there or something equally useful but probably best not to then!

Would be grateful for any advice on what might this cable be used for?? it comes out of the controller for the XF07 front hub kit with 17Ah battery, Cheers, Simon

Yes. I can understand the tyre size issue. However, my current set up with panaracer ribmos 32mm gives an actual measured diameter of 682mm. The KM529 must be using a diameter of around 786mm........a pretty hefty tyre on that baby!! Now I am being a pedant (but that is the reality).

I have recently purchased the XF07 700c front hub kit with 17Ah battery & fitted to a tandem. The first 100 mile is under the belt & I am more than satisfied with the performance of motor hub and battery so far. The only small niggle, & it is small (but if I were following an Audax route it could be annoying) is the discrepancy with the speed & hence odometer. The speed sensor is fitted to the rear seat stay securely & within 5mm of the spoke magnet. The red led on the sensor briefly illuminates on each passage of the magnet & the speed displayed on the KM-529 LCD display is fairly steady (i.e not erratic). With 700c wheel size option entered into the KM-529 the displayed speed is just over 15% in excess of actual speed - i.e 15mph on the KM-529 equals about 12.6mph. I also checked over a fixed 10 mile course and the KM-529 displayed 11.7 miles. I have just entered a 24 inch wheel size option & that has brought the error down to about 2.5%. Unfortunately there is no wheelsize option for 23.4 inch which would see the meter accurate!! Hopefully I am not coming across as a total pedant!!, but it would be interesting to note what associated wheel circumferences are tabulated against specific wheel diameters in the factory settings. Anyhow, I remain very happy overall and the 24 inch wheel size option gives a sufficiently accurate speed/distance for my purposes, although it would be interesting to establish if anyone else encounters a similar discrepancy. Cheers, Simon

I already tried adjusting the wheel sizes to obtain correct speed although it didn't seem to make much difference. I have an exact-ish 10 mile course local to me so I'll check it on that shortly. I am basing the error assumption on comparison with my originally fitted Speedo (front wheel magnet) which has been on for a few years now and has always been fairly accurate (actual wheel circumference is manually input after measuring). Perhaps the hub motor is making that one inaccurate and the newly fitted rear wheel one is good!! Something to check.

I've had a close look at the disc rotor threaded holes & it looks like they may actually give access to the motor hub internals so I've just ordered a slack handful of M5 grub screws to blank the holes up. The tandem is fairly low geared, think it's a 24 / 30 granny so even on the steepest hill around here I can get a half turn on the crank which should be enough for the PAS to cut in. I can't get the throttle close enough to the bar grips really to facilitate a controlled throttle start, I'll have to practice. But at the end of the day it's no hardship for the wife to jump off if things get too vertical. I actually had to turn the juice off today as the power indicator got a bit low. My fault, I was seeing how far I could go before having to recharge. I think the ODO was reading about 75 miles when I turned it off so that's not too bad - obviously it is all dependent on terrain, all up weight, wind direction etc etc but I'm happy with that as a ball park figure for now (I do however think the speed sensor & hence accumulated distance is reading about 15% high). For interest I was pleasantly surprised that the modified tandem weight is now only 5kg more than it was before, 22.4kg without conversion, 27.6kg after conversion (incl. battery). Anyhow, thanks for the comments, cheers, Simon

Thanks for the response. I can't really see myself using the throttle too much (unless it is to amuse the kids) so will probably try and shroud that in a ziplock bag or something. Basque country a nice place to be based, we used to pull in to Pasajes on the Biscay Coast on a small coaster I used to work one. A beautiful approach from the sea, it looked as though you were heading straight into the cliffs. I'll head back there when all the kids have left home.

I have recently fitted a Woosh XF07 front hub kit with 17Ah battery to a 700c cheapish alloy tandem (cromo forks). Very, very happy so far with the product & the customer service from Woosh. Could anybody here give advice as to any special precautions to take when using these conversion kits in inclement weather. I am resident in the North of Scotland where it has been known to rain every so often. The tandem is used daily for ferrying kids to school (doesn't need the e- assist for this really) & for longer runs with the wife and a nipper in a rear seat at times (all up weight in this instance about 175 kg where the motor comes in handy). I am a reasonably fit cyclist so don't mind giving a fair proportion of the ooomph to save burning out the motor! The LCD display unit looks fairly weatherproof, the controller is protected by the battery (when fitted - pretty exposed otherwise), the cable connections appear pretty tight, the throttle looks like it could suffer from some water ingress. I'm inclined to just 'suck it & see' and just head out into the showers, maybe putting an old bread bag or similar over the display if the rain gets particularly heavy. Attach a couple of images of the tentative conversion (still not fully tidied up), should I be carrying more clingfilm on those rainy days?? Thanks for any advice, cheers, Simon
