    Brake cut off query

    Yes, but you will need to source 5V from elsewhere (throttle or PAS) to power the sensor.

    Bosch Active Line Plus versus Suntour Hesc

    Do you have any stats of the total energy used with both bikes?

    Peter Sagan v 81 year old on Gran on an ebike

    Funny advert, but how can they make the claim of "The world's fastest electric bike"?

    I want music on my bike.

    I own a pair of Aftershokz Bluez 2 bone conduction headphones, but they suffer the same issue you describe. Once riding at 20mph+, they are drowned out by wind noise. Also, the sound quality is pretty poor and they're only really suitable for voice audio IMO. I also own a Minirig...

    30 mile each way commute, which bike is best?

    Looks like you got a great deal there! I always enjoy reading about your next mental build. What's your plan for it?

    Heatwave!

    Although excessive levels of heat will affect the longevity of a battery, they will actually deliver MORE power when warm (as opposed to cold) due to increased ionic motion rates. This is why Tesla batteries are preheated when operating in 'ludicrous mode', so to ensure they are able to deliver...

    How to add a throttle to a Carrera Vengeance E Spec

    Okaaaaay, that makes way more sense. I assumed that it was a standard cadence PAS behaviour where the pedal cadence does not affect the motor output and couldn't figure out the mechanism you were using to send a variable signal to the controller. Double kudos to you in that case and the best of...

    How to add a throttle to a Carrera Vengeance E Spec

    Thanks for your reply. So, just to confirm, does the standard (unmodified) PAS behavior on the Carrera Vengeance vary the motor power with pedal cadence?

    How to add a throttle to a Carrera Vengeance E Spec

    Good job! Can you please clarify the end result? Is the throttle output fully variable, or is it single speed, regulated by the current PAS level selection? EDIT: Having re-read the thread and watched your video, it looks like you've achieved variable motor speed using the throttle output, but...

    Brakes acting up yet again.

    Really? You think £30 is expensive for such a job? I'm interested to hear what you think would be a fair charge?

    has d8veh left this time for good?

    Blimey, I think you're right. d8's posts are still present, but they are linked with user 'Deleted member 4366'...

    Traction problem with Big Bear

    I don't mean to burst your bubble, but I think that dual motors makes the bike non-compliant with EU regulations.

    Waterproofing

    Having already stated this multiple times, I couldn't agree more. DD motors are so much better suited for hot-rodding and those that do go this route, tend to want to eek out every last bit of performance. This is where FF + hubsinks shine - I think the phrase is "game changer". The other side...

    Waterproofing

    You're forgetting that FF is magnetic and therefore forms columns between the stator and magnets. It bridges the air gap enough to have a dramatic effect on cooling. If you want greater bridging, use more FF. This will of course increase motor drag though. Also, FF suitable for this application...

    Waterproofing

    Without even looking at your numbers, there's so much wrong with your general understanding of ferrofluid. Firstly, it does bridge the air gap - it is attracted directly to the magnets, that much is plain to see when it's applied. It has been calculated through prior testing and research that...

    Waterproofing

    You show a fundamental misunderstanding about the role ferrofluid plays in hubmotor cooling. It's there purely to bridge the gap (displace the air) between the stator and motor casing, allowing faster heat transfer from where the heat is generated.

    Waterproofing

    Apart from on a low power folder, I've all but given up with geared hubs. I wouldn't want to live with the mess of oil bath cooling anyway. Also, the downside of increased drag negates the advantage of them being able to freewheel. Sorry, that's just plain wrong. By far the greatest heat...
