Thanks all.

How about the PAS sensor. Has anyone got it to work on a Thorn using either the left or right side version?

The axle reacts the electric motor rotation and it is imperative that it can not spin in the fork (or the wiring will twist badly and get wrecked).  ‘Torque brackets’ are available in stainless steel on ebay that go on the axle and bolt to the mudguard stay holes, but are probably only made for a 10mm axle.

Rather than modifying the fork, I'd be inclined to try filing flats on two sides of the axle, where it protrudes past the bearing locknuts. If you measured carefully to make sure they were in the same plane side-to-side, I think removal of only the threads (0.5mm each side) would fir the dropouts while still leaving adequate full threading for locknuts.

Best, Dan.

Thanks. Could do yes. I’d rather avoid either!

Filing down is something I could live with.
I’m less convinced that the PAS sensor will fit and there doesn’t seem to be a way to check

On my wife’s hybrid I had to file the front fork dropout to 10mm to take the hub motor axle.   Could you find an older / cheaper fork?

Electric Conversions of "Manual" Bikes / Bafang PAS senso

Hi. Has anyone recently converted their Rohloff-equipped Thorn with a Bafang front motor?
There’s a couple of issues Id like to understand.

The online sales stores (Amazon, etc) offer a left side and right side PAS sensor, neither of which seem very compatible with Thorn’s BB. Has someone fitted either of these successfully?

Also the Thorn dropouts are 9mm. I can’t tell but I imagine the Bafang kit requires 10mm. Has anyone successfully installed this and what was the solution?

Thanks!

As in title. Seller is very keen.

I don't think I'd try and cycle up something that long and steep nowadays. I did go back to the Lakes in 2001 with my wife and one daughter during the foot and mouth epidemic (not so many people about), and went up Hardknott in a hired left-hand drive Citroën ZX with a fairly big diesel engine.

As I had already been living in France for several years and there were no other vehicles on the road at the time I drove the car up the pass the French way, relatively fast, with gear changes before and after the bends to keep the revs up, and was surprised to see walkers near the road clapping, maybe in irony.

My "overkill" setup did, however, enable me to cycle up Hardknott pass in the English Lake District, the steepest bit on that hill is supposed to be about 30%.

Alas! We were all younger and fitter c1977. Congratulations.

I've been over the Hardknott Pass on foot (conclusion: machismo is stupid) and twice in Range Rovers I was testing for various magazines thirty years apart. I much preferred the Range Rover Way...just saying.

Anyone tempted to emulate Martin's Epic Transit of the Hardknott should note that it may be hours, perhaps even days, before a car comes along, so make sure your bike is in good order and you have enough spares with you.

And mind the feral sheep. There was this ram, who apparently thought we coveted its females, who head-butted the door of the Range Rover, through which I'd just escaped its enraged attentions, so hard that it got stuck by its horns sticking through the aluminium doorskin. I climbed over the centre console and my companion, and gave the jack another couple of strokes so that the ram's front feet we're off the muddy road and it hung from its horns at an angle where it couldn't release its horns by scrabbling in the slippery mud with its hind feet. Then I packed the flat wheel away neatly, checked the wheel nuts, and stood for a couple of minutes fixing angles and distances in my mind while the bloody ram stared at me with bloodshot eyes, probably trying to convey, 'Are you dissing me by working right here in my personal space?' I said to my companion through the sunroof, 'Wind down the rear passenger window on my side.' Then I grabbed the ram by the lowest joints on its rear legs and lifted its back end so it could free its horns from the door. It twisted around with unbelievable speed, presumably hyper-motivated by my impertinence in coming so near its only reason for existence, but I was already twirling like a Scottish rugby forward tossing the caber at the village sports day, and when the animal was high enough and I was moving fast enough, let it go to fly over the roof of the car to land about fifty feet on the downside of the mountain to give me time to salvage the jack, which I thought, correctly, we would need again, throw it through the back window, get into the car and get it moving. That ram was incredibly fast because in the less than the ten seconds it took me to let down the car and throw the jack into the car and me through the driver's door, it reached us and, as the car passed it, used its horns to score the rear quarter of the car.

I've been convinced ever since that you can't hate sheep enough.
