A good course of action might be to think about all these aspects, do a bit of research, and then visit a good bike shop for a chat and view bikes you're interested in 'in the flesh'. Assuming of course you can find a retailer with any stock - or have they managed to catchup after the run on sales ...

Instead of brute force, might be worth heating it. I had a bottom bracket that was seized, and wouldn't budge. Heated with a blow torch, and it undid as if fitted yesterday. Guessing unequal expansion of various parts / differing metals just broke all the seized interfaces apart. May be worth a try....

Just bought a Ravemen front light - comes with USB C, and can be charged (via external battery pack such as a power bank) whilst also being used, in the event that the internal battery runs low. Has 2 leds - flood and dip (specifically for on road use to reduce glare) - covers all bases for me.

How bright? How long do you want the battery to last? How much are you looking to spend?

Apologies if it’s been posted already but from the website. Battery runtime extension with USB C charging port Extend the runtime of the battery by connecting with external power source for emergency lighting when the light is in low power, no worry to be left in darkness Thanks for the reply. My q...

The OP's original message asked why nobody wanted old maps, and that he had failed to sell any despite advertising on e-bay and elsewhere. That said, I PM'ed asking which ones were for sale as I could be interested. Nothing!!!! So, do you really want rid? I want rid of all not piecemeal and was pre...

Wonder how long it takes a battery powered angle grinder to arrive on the scene?

Thanks for all the replies, plenty of ideas to have a go at.

I'm putting the data in the thread in case someone knows the answer. The best that I can do at the moment is: * USB voltage is invariant. * In the absence of one of the high-current control protocols (which aren't mentioned in the instructions) the only other property is the current. * So the next ...

From the instructions: Screenshot 2020-12-05 at 21.40.11.png http://www.ravemen.com/upload/file/1576632855.pdf Jonathan Not sure what you are saying. I've read the instructions (they are the same as those that came with the light) and already know that it will be limited to running at 800 lumens wh...

OK - thanks.

Whatever it is, it doesn't seem up to the job. Should it be?

(I'm trying to work out what current is needed.)

I've had it a while, but think it's this here

I use one of these in my velomobile, running two 50 lux headlights and some tail lights. Would need to be out of the weather, though. Thanks for the info. Will have a look if they do anything more than 3000ma, which would be ok in emergencies, but even on med power would only give me up to an hour ...

Don't understand the question. Do you mean 32v?
