Re: Strange way to pay

IMHO it is not necessary to protect your 'contactless' cards with the faraday cage type of containers if you have a number of such cards in your wallet/purse. I base this notion on two things: 1. the contactless cards use, as you know, RFID chips - any such RFID reader 'aimed' at your wallet will ge...

Re: What 18650 batteries for your battery pack?

Thank you to all who have replied so far - I'm learning a lot and each posting prompts me to delve further into the subject. The term 'smaller motors' or 'low power motors' - can someone give me a general idea of what (watt :-) ) is meant here? Are we talking of 500w or less or 250w only. As said up...

What 18650 batteries for your battery pack?

So I'm currently at the research stage of converting the good lady's bike to an eBike (current favourite is one of the TSDZ2 mid-drive units) and have fallen upon the options for battery packs - so some questions if you'll indulge me please? > Firstly, I have read posts on here saying about a UK bat...

Re: Mid Drive motor with Rohloff

Thanks for that TigerBiten Since posting I found a post on this topic on the Endless Sphere forum where someone is comparing the BBS02 against the TSDZ2 and had this to say: Gear sensor: Also, I purchased and installed a gear sensor for the BBS02. Changing gears under power can cause them to grind a...

Mid Drive motor with Rohloff

So a newbie to eBikes but not biking (or the ebike section of this and the Pedelc forums)- > I am looking to convert my wife's steel tourer to an eBike (and likely to go for one of the TSDZ2 units) > The Bottom Bracket is a standard 68mm (not eccentric) > The IGH is a Rohloff with chain tensioner > ...

Re: Hacked Bafang Road bike conversion

Technically interesting of course but idiotic to say the least. Standard brakes I notice - I dread to think what might have happened if an emergency stop was needed.

Re: Naive battery question

That sounds a useful answer to unexpectedly finding a flat battery -open door indicator light not seen in my case. Is it something available on the market or a self assembly set up? Go to eBay or Amazon and search for something like 'car jump starter' to see the massive array of LiPo type starter p...

Re: Bike speedo v GPS

And of course there's the battery management side of things - the Speedo batteries on my kit last at least a year - it's a different story for the batteries in GPS gizzmos. Mind you, many people are ditching their speedos which means they are cheap to buy on ebay 2nd hand and I've got them on all my...

Re: Headset cartridge Bearing-Shimano BC1-help please

I take it that is one of the old threaded headsets in 1" variety? yes If you can't find the same headset or suitable replacement bearings there are plenty of decent quality ISO 1" threaded headsets around. You will have to watch out for stack height though as of 105s are quite short. If i...

Re: Headset cartridge Bearing-Shimano BC1-help please

I believe you need Shimano part number 78V 9803. These are very hard to find because Shimano stopped making them. Cyclebasket had them until recently (just one in stock a couple of months ago) but they’re now sold out. I see it here for £25 , but I have never heard of that shop so can’t vouch it. T...

Re: Galaxy Steel Frame repair advice please

Well, I've learnt a lot about seat stays and their fixing methods from these posts - thank you one and all for sharing your knowledge. As has been said, the particular way Dawes chose to 'attach' the seat stays does leave a lot to be desired in terms of the rather small attachment area - but hey ho,...

Headset cartridge Bearing-Shimano BC1-help please

The lower cartridge bearing in my 1989 Dawes Galaxy has suffered water ingress and requires replacing but I am unable to find anything on the web when I search for "Shimano Cartridge Bearing BC1" or similar phrases. There may be alternatives of course, but I do not know how such bearings a...
