    Grenfell Tower

    the police knows everyone is watching their every move and press release. why should anyone trust you more than me? and you and me more than the police?

    250w BBS-HD?

    I think they just made a shroud for a BBS motor to make the bike looking like a MaxDrive or a Bosch. The fundamental issue with bottom bracket type CD motors is the poor support for the bottom bracket compared to the Bosch or Maxdrive motors. The non drive side is supported by two M6 bolts, no...

    Grenfell Tower

    The number 600 residents is a guestimate, I could have said 300 or 400 for 106 flats. With London being a 24 hours a day city, in the summer, people were on holiday, go out to work or for other reasons. Who can guess the number who are not in? I could say 100 or 200. Do you know how many walked...

    1st ebike conversion road bike or MTB with skinny tires? which starter for 20 mile commute each way

    I have placed an initial order for 48V kits which should be compatible with the Q128H but running at 17A instead of 20A. It's meant to be used with the SWX02C rather than Q128H. The 48V kit should arrive in September and priced to compete with bmsbattery.

    Halfords Carerra crossfire e

    the motor may have speed sensor. How can you tell the speed sensor wire from the hall sensors? how can you tell which wire is the torque signal and which is the PAS?

    250w BBS-HD?

    it looks definitely a bottom bracket motor added to a bottom bracket shell.

    Grenfell Tower

    oldtom, I know where you stand on the political spectrum but your last post was blatantly OTT. The police do what they can to identify the victims so please, do refrain from trying to make out that our police is incompetent or worse, politically motivated to minimize the number of casualties...

    Brexit, for once some facts.

    Liam Fox was there at last night QT. He didn't do very well.

    250w BBS-HD?

    thanks BE. I tucked the motor originally between the seatpost and chainstays in this original Woosh CD bike that I took to Redbridge in 2013.

    250w BBS-HD?

    the motor looks like a Bafang BBS01B. They may have borrowed my idea to place the motor inside the triangle like the Woosh Krieger:

    Halfords Carerra crossfire e

    you need the pin-out of the Suntour motor cable before considering a new controller. You will also lose the torque sensor and the pedal sensor.

    Brexit, for once some facts.

    JC does not want the brexit row to divide the Labour votes. He much prefers to talk about austerity, disparity in wealth etc for understandable reason. JC wants to avoid the brexit subject altogether.

    Brexit, for once some facts.

    as I understand it, Labour does not have a target on EU immigration but wants to control it. Labour does not mind the superiority of the ECJ in some area but still would like a mechanism where the head judge is jointly selected by the UK and EU. Labour also favours remaining in the EU customs...

    Brexit, for once some facts.

    I watched Caroline Flint (Don Valley Labour) confirmed today when interviewed by Andrew Neil at lunch time that the brexit position of Labour front bench is to leave the Single Market and possibly staying in the customs union.

    Most powerful eBike for long uphill journeys?

    torque multiplier = power multiplier because power = torque * rotational speed as you already said. You and the motor turn the same chain wheel, therefore bound to the same rotational speed so the function can be simplied to just assist ratio = motor's torque / rider's torque. The cadence is...

    as much as I can be from what I have seen and read, yes.

    Motor reliability

    at least in the first 1-2 years. my personal experience seem to correlate to the following general rules: - the lower power, the more reliable your motor will be. - front motor on a suspension fork seems to be more reliable than unsuspended rear motor on the same controller. - internal...

    Most powerful eBike for long uphill journeys?

    I understood what you said, you change the way you input your power by changing gear and pedaling faster. But that doesn't change the assist ratio between user input and motor output. That is the important point. The system still gives you the same assist ratio. In turbo, that's *3. If you...

    Help us build a better Ebike battery

    No, I don't give out that advice. Nor do I tell people how to reduce the shunt resitors' value.

    Help us build a better Ebike battery

    I read the same posts from Basicasic like everyone else, I did not find his posts misleading in the slightest. Like in most situations, the devil is in the details. How, for example, do you know you are charging your battery to 80% of its full capacity? For me, it's easy, that is to charge it up...
