Here's that knowledgeable young chap again giving a comprehensive presentation on what causes ebike fires.
He gave one on regenerative braking once before where he shows an impressive knowledge of electro - mechanical stuff ( I've posted here before somewhere )
I thought he was bang on the money with this one.

Re: Cycle Retail In Meltdown.
I Googled where Pinnacle bikes are made -- Ans -- Taiwan but what was more interesting was that the forum I found that on were having the same sort of discussion as we are on this forum 14 years ago and it's not even a bike forum.

Re: Servicing Union SP-808 or Wellgo LU868 pedals
You'll need this
For adjusting cup and cone ball bearings in pedals. The 9 mm socket fits inside the 11mm socket to lock one against the other. -- couldn't get mine locked so bought this DMR V8 pedal tool which fits my XLC pedals for £10.99 off eBay -- works perfect.
The 1/4" ratchet and 13mm spanner is not supplied just the two sockets but most spanner friendly bikers will have these common tools.
Edit -- just used it today on my wellgo pedals.

Re: Night p*nct*re scenario comes to pass
I've never had a front light fail either but have had a battery run out cos I was testing how many commutes I could do on one charge when I first got the 400 cateye.
The cateye 400 was more powerful than the 100 lumin cateye I'd had before but did less time surprisingly even though it is much heavier.

Re: Night p*nct*re scenario comes to pass
This is one of the reasons I singled out the unilite because of it's more focused beam which is good enough to light a pitch dark road well enough to get home ( did 20 miles with one of my head torches I bought about 3 more of the H2 's they are just that good -- all of them still work perfectly -- I lend them out to sons various times but always make sure they return. )Pebble wrote: ↑11 Mar 2024, 12:24pmaye - but it might mean you can continue to ride on an unlit road if the main light fails and you are miles out in the countryside. (you can always stop and get off if a car comes along)mjr wrote: ↑11 Mar 2024, 10:42amJust carry a back-up light. Headtorches are never suitable for riding by, because they show a white light, which means front, to the rear when you look backwards. Most of them also dazzle whoever you are looking at, which is illegal whether or not the light is attached to a bike, and a really dumb idea when the victim can injure or kill you.
I got a little head torch in poundland a few years ago, (£1.50 or something) I was so impressed I went and bought half a dozen of them, have them in the van and car and tool box, bike as emergency ights... fantastic little lights, I think they all still work.
It's always the front cycle lamp that gives up first cos you need it to see the road/lane so it's on continuous -- the rear is blinking and only there for your visibility reasons so it lasts for days. So it's vital to carry a back up or a good head torch.

Re: Night p*nct*re scenario comes to pass
The best head torch in my long experience with them ( I've had many different makes since the 1980's ) is Unilite but I buy the one with the single AA battery because it's a lot less fiddly than a 3xAAA when changing the battery in complete darkness ( which happens although with the Unilite you get plenty of warning as the light gets gradually dimmer near the end of the battery) one AA lasts a full day of non stop working in darkness ( I've done it many times )
I change my bicycle bag head torch battery once a year just before my first cycle / camp excursion of the year.
Also it's extremely lightweight

It's not the best Unilite torch -- it's no longer available -- slightly heavier but extremely robust is my old Unilite waterproof shock proof one in which the battery was even easier to change ( I can change it just by feel -- have done many times and demonstrated this to many friends )
Edit -- found one -- https://www.pewelectrical.com/site-esse ... -uk172.htm?
The new H2 is very good too because of it's much lower profile but the old one was bullet proof.

You could sell the op one of yours and buy a new one.djnotts wrote: ↑10 Mar 2024, 12:31pmHold my hands up to that! Last 5 years? I don't keep count... 20 - 25 maybe. 5 in garage, between them cover any sort of ride/terrain that I can still ride. And 2 Bromptons.
My point about 2nd hand is different really - can easily save at least 50% on a bike that is so near to new that will still run for decades.

Re: Knee protection please
Yes you've already said that but do you know of something with more padding at the knees ? -- I'm not an expert on this sort of stuff.pjclinch wrote: ↑10 Mar 2024, 12:54pmIt doesn't say anything about built in knee pads in the link you shared, it says, "Reinforced 300 Denier polyfabric panels on the saddle area and on the knee for durability. That's a slightly thicker bit of fabric, not a pad. 300 denier is quite a bit thicker than typical riding trousers, but still less substantial than e.g. a typical rucksack fabric. It won't wear out or tear that easily, but it's not padding and will do nothing special to keep padding in placeCowsham wrote: ↑10 Mar 2024, 12:20pmYou're the boy that could give advice on which mtb trousers to use with all years of training and knowledge about mountain biking. There's bound to be something in a Lycra style legging with knee protection as well as the bum padding he could wear under his jeans for example.
The great thing about cycle leggings is that it keeps the padding in place better than just separate saddle pads/ covers so I'd expect built in knee pads have a similar advantage.

Standard risk management, PPE comes at the bottom of what to do, not having the problem in the first place is significantly better.
Reinforced knees on trousers are good against abrasion but don't take much away from an impact, so for some values of "help".

Elbow pads might be good for us of the older variety. MickF could've done with some last year when he went down at a roundabout and scraped his to the bone. The cycling experience he has probably out trumps us all.

Re: Knee protection please
He specifically said he didn't want help not falling off the bike just which knee protection to have. You've heard of unsolicited advice well you've taken that one step further. Falling off happens to everyone except the ones that don't get on a bike to start with.

Re: Knee protection please
He did say he wasn't asking for advice on the not falling off bit but that's exactly what he got reams of.pjclinch wrote: ↑10 Mar 2024, 7:51amI found my thoughts running along the same lines (wrists and collar bones probably most susceptible, and you can't brace your way out of a collar bone fracture). And while it wouldn't necessarily be £0, some training/coaching might be very good value.Psamathe wrote: ↑9 Mar 2024, 7:40pm Or maybe try and solve the underlying problem?
eg if somebody asked me about better seat belts for their car because they kept hitting things then I'd respond that better seat belts won't solve the problem and easier and cheaper to sort out why they keep hitting things.
If you are falling off so often it wont be just your knees that will suffer but other body parts as well as bike damage. In my personal opinion the paths shown are not so challenging as to cause so many falls. Getting distracted? Bike handling sub-optimal?, etc.
ie you can protect your knees for £0 by not falling off.
Does the following seem familiar at all?
I coach (very) beginner mountain biking to kids from "just graduated from balance bikes" level and the most common cause of falls and stumbles is stopping and starting when they can't do what they've been used to and stop sat on the saddle with two feet down flat. If anything seems like it's going wrong default is hit the brakes, stay on the seat and put two feet out. That's great on a balance bike, it's a disaster on a mountain bike set up with the seat for pedalling: no feet on a pedal and there's no power and it's very hard to move weight around for balance, and because a MTB bottom bracket is high it's pretty much impossible to get two feet down at the same time if sat on the seat and one tends to need to lean quite a bit to get one foot down, resulting in much staggering and barely controlled dismounts (and where that's been set in motion by a worried reaction to difficult ground, the staggering may well be in a really awkward place).
We stop that happening by making a default stop a thing where the rider puts all weight on one pedal at 6 o'clock and steps down ahead of the seat, putting the other foot down flat on the ground. To start, pull the pedal up from 6 o'clock to about 2 and stand on it, only getting back in the seat once you're going. And that eliminates the great majority of falls IME.
Get that dialled in as a default and all the silly low-speed tight-turn fiascos simply stop right away with one foot flat down rather than an ungainly dance with two feet flailing about too high above the ground before keeling over sideways.
Here's the one-foot-down. In this pic the rider has pulled their pedal up ready to start, on stopping the pedal with the foot on will be at 6 o'clock. Once stopped you have a triangle for optimum stable support (two wheels on the long side, a foot flat on the ground for the third) and no balancing on tippy-toe needed.
If you're already doing that...
The chair of our local advocacy group took a different method when encountering balance problems as she got older, which was an e-assist trike rather than bike. Once you've dialled in to the steering differences it's much harder to fall off a trike, particularly starting/stopping.
Pete.
