    Hub or Mid Drive? Any views?

    I've just been through some guidelines for approval that give clear guidance on all the requirements and standards. I can't find anything in there that says anything about batteries. I did find that the low voltage directive applies to anything over 50v AC and 75V DC. Normal Li-ion 48v...

    Hub or Mid Drive? Any views?

    The low voltage directive says 50v AC and 75V DC. I can't believe that the machinery directive would do anything other than point to the low voltage directive. My guess is that you've been misinformed. Can you tell us the source of your information?

    Hub or Mid Drive? Any views?

    You have to specify the conditions. Do you want maximum torque at the back wheel that you can't actually use, stall torque, torque at 8 mph in bottom gear, max torque at normal pedal cadence, torque at 15 mph or what? A hub-motor gives much more measurable and meaningful torque figure because...

    LCD S866 + Brainpower controller

    Good point. They need to change it to something with a more obvious answer, like "What sort of person would vote for remain in the EU referendum?"

    Have I got too many spacers in?

    Screw all the cable adjusters right in. Undo the cable clamp screw. Put the chain on top gear and the shifter in top gear. Adjust the position of the derailleur using the top gear adjuster screw. Pull the cable to take out any free-play and clamp it with the clamp screw. Use the shifter to pull...

    Hub or Mid Drive? Any views?

    With a crank motor, the torque at the back wheel depends on which gear you're in and the actual gearing. You can change it with different sized chain-wheels or bottom gear sprockets. You can get 1000Nm if you want. Also, it depends on your pedal speed. You only get max torque at low pedal speed...

    Battery charger

    IIRC, one red light shows that the charger is switched on. The other behaves conventionally, i.e. off when disconnected, red when charging and green when charged.

    Bike great for 6 months now LCD claims no charge on charged battery, motor doesn’t work

    All your symptoms point to water in the LCD has destroyed it. Test by disconnecting it, then short the red to the blue wire and short the two data wires (not red, not black and not blue). If it works OK on the throttle, you need a new LCD.

    Professor Hugh Jardon says the opposite, and he's the one that's right.

    Brexit, for once some facts.

    That analysis is incorrect. Labour and Conservative party policies might be remain and leave, but it doesn't follow that all their voters are. Many people vote for a party for reasons other than Brexit.

    They didn't know what they were voting for. We better have another election.

    11 years old changes everything. You should have mentioned that earlier. You can forget everything I wrote above because you have an old fashioned cup and cone BB. See what I wrote in the other thread. Try straightening it first. you have nothing to lose and everything to gain. I successfully...

    Hub or Mid Drive? Any views?

    I think that the companies pushing mid drives are doing it from a motive for profit. Also, false logic persuades people that the crank drive should be more efficient because you can use gears to keep it spinning at optimum RPM, but that's a fallacy that's been exposed by actual tests. It would...

    Brexit, for once some facts.

    John Durham has opened a formal criminal investigation into irregularities that were exposed in the IG's report. Results are expected round about June. Do you want to stand by your beliefs and take a bet with me whether anybody will get prosecuted?

    Brexit, for once some facts.

    Anybody been following the Trump impeachment saga? The IG report seems to have exposed the whole thing as a vicious hoax. Several people are going to get charged with criminal activities for falsifying and falsely representing evidence. It goes right to the top of the FBI. It's not looking good...
